These are low-cost, frequently replaced parts.<\/li>\n<li><strong>Thread breaking or loose stitches<\/strong> \u2014 check the thread tension assembly and needle plate for burrs first; a bent or wrong-type needle is another common cause.<\/li>\n<li><strong>Machine not starting or running erratically<\/strong> \u2014 on computerized F4\/F5\/F6-type models, check the error code on the display first (see above); it often points to the motherboard PCB or speed control pedal rather than the motor itself.<\/li>\n<li><strong>Bobbin winding unevenly<\/strong> \u2014 the bobbin winder assembly or its rubber wheel.<\/li>\n<li><strong>LED work light flickering or not working<\/strong> \u2014 a straightforward replacement on models with a built-in light, and worth checking before assuming a bigger electrical fault.<\/li>\n<\/ul>\n\n<h2>Is Jack a Good Sewing Machine Brand? Jack vs Juki<\/h2>\n<p>Jack (China) and Juki (Japan) are two of the most common industrial sewing machine brands found in Indian garment units. Juki has a longer manufacturing history and is often seen as the more established name for heavy, continuous-duty production; Jack has built its reputation more recently around energy-efficient direct-drive motors and computerized features like the F4\/F5\/F6 series at a generally more accessible price point. In practice, both brands are widely used side by side in Indian factories and tailoring shops, and the right choice usually comes down to your specific machine type, budget, and what your local mechanics are most familiar servicing. Either way, keeping genuine or well-matched compatible spare parts on hand matters more for uptime than the brand name alone.<\/p>\n\n<h2>How Much Do Jack Spare Parts Cost?<\/h2>\n<p>Pricing varies a lot by part type. On our site, feed dogs start from \u20b935 and presser feet are \u20b980 for the original Jack foot, needle plates and tension sets are usually mid-range, and electronic components like motherboard PCBs and control boxes cost significantly more since they're precision electronics rather than simple mechanical parts. Browse the specific model category above for exact current pricing on the part you need.<\/p>\n\n<h2>Original vs Compatible Parts<\/h2>\n<p>For everyday wear parts \u2014 presser feet, feed dogs, needle plates, bobbin winders \u2014 a well-made compatible part performs the same as original and is the more economical choice for routine maintenance. For electronic components like motherboard PCBs, sensors, and speed control pedals, matching the exact connector type and part number reduces the chance of a fitting issue, since these can vary between production revisions of the same model.<\/p>\n\n<h2>Who Buys Jack Spare Parts From Us<\/h2>\n<p>Tailors and alteration professionals, boutique owners, garment manufacturing units, sewing machine mechanics and technicians, dealers, and training institutes running Jack machines across India \u2014 whether it's a single replacement part or ongoing stock for a repair business.<\/p>\n\n<h2>Ordering Jack Spare Parts from StitchPartner<\/h2>\n<p>We deliver Jack sewing machine spare parts across India with <strong>Cash on Delivery available on eligible orders<\/strong>. If you're unsure which series or part your machine needs, send us a photo of the machine's data plate or the worn part, and our team can help confirm compatibility before you order.<\/p>\n\n<h2>Frequently Asked Questions<\/h2>\n<h3>How do I know which Jack model I have?<\/h3>\n<p>Check the data plate on your machine, usually near the handwheel or on the machine arm \u2014 it shows the exact model number. Several Jack models look visually similar, so relying on the printed model number is more reliable than appearance alone.<\/p>\n<h3>What should I do if my Jack machine shows an error code?<\/h3>\n<p>For F4, F5 and F6 models, check the code against our <a href=\"https:\/\/stitchpartner.com\/jack-f4-f5-f6-error-codes-guide\/\">JACK F4\/F5\/F6 error codes guide<\/a>, which covers E1 through EZ with causes and fixes. For other models, note the code and your exact model, confirm the power supply and connectors, then restart the machine.<\/p>\n<h3>Is Jack a good brand for industrial sewing machines?<\/h3>\n<p>Jack is one of the most widely used industrial sewing machine brands in Indian garment units, known particularly for energy-efficient direct-drive and computerized models. It's generally viewed as a solid, accessible option alongside brands like Juki, Brother, and Siruba \u2014 reliability in practice depends more on proper maintenance and genuine or well-matched spare parts than the brand alone.<\/p>\n<h3>How does Jack compare to Juki?<\/h3>\n<p>Juki has a longer manufacturing history and is often preferred for heavy continuous-duty production, while Jack is known for energy-efficient motors and computerized features at a generally more accessible price point. Both are widely used in Indian factories, and the better choice depends on your specific use case and budget.<\/p>\n<h3>How much does a Jack feed dog (dati) cost?<\/h3>\n<p>Feed dogs for Jack single-needle lockstitch machines start from \u20b935 on our site, depending on the exact model and tooth configuration. Check the category matching your machine model for current pricing.<\/p>\n<h3>Why does my Jack machine skip stitches or break thread?<\/h3>\n<p>The most common causes are a worn feed dog, a burred or damaged needle plate, an incorrect or bent needle, or incorrect thread tension. Check these in order before assuming a more serious mechanical fault.<\/p>\n<h3>Are parts interchangeable between different Jack models?<\/h3>\n<p>Some mechanical parts are shared across similar machine types, but electronic components like motherboard PCBs and control boards are typically model-specific. Always check the category that matches your exact model before ordering electronic parts.<\/p>\n<h3>Do you offer Cash on Delivery on Jack spare parts?<\/h3>\n<p>Yes, COD is available on eligible orders and locations across India, along with prepaid card and UPI payment at checkout.<\/p>\n<h3>Can I order Jack spare parts in bulk for a factory or repair shop?<\/h3>\n<p>Yes, we regularly supply garment factories, tailoring units, and repair shops with multiple spare parts per order.

Read the part number on the old board<\/h3>\n<p>Unplug the machine, open the control box and read the number printed on the green board. Order that exact number. For Jack machines you can also check our <a href=\"https:\/\/stitchpartner.com\/jack-sewing-machine-part-numbers\/\">Jack sewing machine part numbers lookup<\/a>.<\/p>\n<h3>2. Check the generation of the board<\/h3>\n<p>Some machines have an old type and a new type of the same board, for example on the Jack F4 line. Their connectors and firmware can differ, so match the type, not just the model name.<\/p>\n<h3>3. Compare connectors and voltage<\/h3>\n<p>Count the connector sockets and compare their layout with the old board. A board can physically fit and still lose trimmer, foot lifter or display functions if pins are missing.<\/p>\n<h3>4. Send us a photo before you order<\/h3>\n<p>If you are not sure, send a photo of the old PCB and the machine model. We check the match first, so you do not pay for a board that will not work.<\/p>\n<h2>Motherboard, PCB, Control Board and Control Box: What Is the Difference?<\/h2>\n<p>Buyers use these words for the same part, but a control box is the casing that holds the PCB, the power supply and the connectors. A motherboard replacement is only the board inside. If your control box is damaged or burnt, ask us whether you need the board alone or the full box such as the <a href=\"https:\/\/stitchpartner.com\/product\/direct-drive-servo-motor-control-board\/\">direct drive servo control board<\/a>.<\/p>\n<h2>Signs Your Sewing Machine PCB Has Failed<\/h2>\n<p>A failing board usually shows erratic motor speed, no reaction to the foot pedal, a frozen or blank display, or no power despite a good socket. Before you buy, rule out a loose pedal wire or a faulty motor. Our guides on <a href=\"https:\/\/stitchpartner.com\/sewing-machine-servo-motor-problems-error-codes-troubleshooting\/\">servo motor problems and error codes<\/a> and <a href=\"https:\/\/stitchpartner.com\/jack-sewing-machine-error-codes-all-models\/\">Jack error codes for all models<\/a> help you tell a board fault from a motor fault.<\/p>\n<h2>Sewing Machine Motherboard FAQ<\/h2>\n<h3>What is the price of a sewing machine motherboard in India?<\/h3>\n<p>Main PCB control boards in our catalogue cost between \u20b91,500 and \u20b94,650, depending on the machine. Jack A2B is \u20b92,900, Jack 781G is \u20b94,650 and Qi Xing QD8633 is \u20b93,100. Display panels and pedal boards cost less, from \u20b9300. Prices on this page are live catalogue prices and COD is available.<\/p>\n<h3>How do I know which PCB fits my sewing machine?<\/h3>\n<p>Match the part number printed on your old board, not the machine's looks. Then compare the connector layout and the voltage rating, and check whether your board is an old or new type. Our stock list above shows the part number for each board, so you can compare it before ordering.<\/p>\n<h3>Can I use a universal or generic PCB instead of the original?<\/h3>\n<p>A universal board works only where its connector layout and functions match your machine, for example the direct drive servo control board for servo motors. For machines with auto trim and sensors, a model-specific board is safer, because a generic board may not drive every function.<\/p>\n<h3>How do I know if the PCB is faulty and not the motor?<\/h3>\n<p>If the motor runs only at full speed, stops at random, or ignores the pedal while the pedal and wires are good, the board is the usual cause. If the machine has no power at all, check the plug, fuse and power cable first. When in doubt, send us the symptoms and the machine model.<\/p>\n<h3>Are Jack A2B and Jack A2C PCBs the same?<\/h3>\n<p>No, treat them as different boards. Jack A2B uses part number 19510031200, while the A2-CZ board uses 9950014900. Both are in stock here, so compare the number on your old board before you order. Do not swap them just because both belong to the A2 range.<\/p>\n<h3>Do you deliver sewing machine motherboards across India with COD?<\/h3>\n<p>Yes, we ship pan-India and COD is available on these boards. Check the product page for the live price and stock status before you place the order, since stock changes through the day.<\/p>","parent":0,"count":45,"filter":"raw","image":""}],"product_tag":[{"term_id":4082,"name":"19510031200 PCB","slug":"19510031200-pcb","term_group":0,"term_taxonomy_id":4082,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":2499,"name":"Garment Machine Spare Parts","slug":"garment-machine-spare-parts","term_group":0,"term_taxonomy_id":2499,"taxonomy":"product_tag","description":"","parent":0,"count":9,"filter":"raw","image":""},{"term_id":3128,"name":"industrial sewing machine PCB","slug":"industrial-sewing-machine-pcb","term_group":0,"term_taxonomy_id":3128,"taxonomy":"product_tag","description":"","parent":0,"count":13,"filter":"raw","image":""},{"term_id":4083,"name":"Jack A2B controller","slug":"jack-a2b-controller","term_group":0,"term_taxonomy_id":4083,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":4081,"name":"Jack A2B main board","slug":"jack-a2b-main-board","term_group":0,"term_taxonomy_id":4081,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":4080,"name":"Jack A2B PCB","slug":"jack-a2b-pcb","term_group":0,"term_taxonomy_id":4080,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":4086,"name":"Jack A2B spare part","slug":"jack-a2b-spare-part","term_group":0,"term_taxonomy_id":4086,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":3284,"name":"Jack control board","slug":"jack-control-board","term_group":0,"term_taxonomy_id":3284,"taxonomy":"product_tag","description":"","parent":0,"count":3,"filter":"raw","image":""},{"term_id":2518,"name":"Jack sewing machine parts","slug":"jack-sewing-machine-parts","term_group":0,"term_taxonomy_id":2518,"taxonomy":"product_tag","description":"","parent":0,"count":7,"filter":"raw","image":""},{"term_id":3706,"name":"Jack sewing machine PCB","slug":"jack-sewing-machine-pcb","term_group":0,"term_taxonomy_id":3706,"taxonomy":"product_tag","description":"","parent":0,"count":2,"filter":"raw","image":""},{"term_id":3271,"name":"lockstitch machine PCB","slug":"lockstitch-machine-pcb","term_group":0,"term_taxonomy_id":3271,"taxonomy":"product_tag","description":"","parent":0,"count":6,"filter":"raw","image":""},{"term_id":3289,"name":"PCB replacement","slug":"pcb-replacement","term_group":0,"term_taxonomy_id":3289,"taxonomy":"product_tag","description":"","parent":0,"count":3,"filter":"raw","image":""},{"term_id":3130,"name":"sewing machine control board","slug":"sewing-machine-control-board","term_group":0,"term_taxonomy_id":3130,"taxonomy":"product_tag","description":"","parent":0,"count":11,"filter":"raw","image":""},{"term_id":4085,"name":"sewing machine main board","slug":"sewing-machine-main-board","term_group":0,"term_taxonomy_id":4085,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":4084,"name":"single needle PCB","slug":"single-needle-pcb","term_group":0,"term_taxonomy_id":4084,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.8 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Jack A2B PCB Main Control Board 19510031200 - Stitch Partner<\/title>\n<meta name=\"description\" content=\"Buy Jack A2B PCB 19510031200 main control board for single needle lockstitch sewing machines.
