Sewing Machine Motherboard Price List (Live Catalogue)

A sewing machine motherboard, also called a PCB, control board or circuit board, runs motor speed, needle position, auto-trimming and pedal response. Price depends on the machine model, not the brand name alone. Here is the current price range by board type.

Which Motherboard Fits Which Machine

Do not choose a board by how the machine looks. Choose it by the part number on your old PCB. Here are the boards we stock for common industrial machines.

How to Choose the Right PCB for Your Machine

1. Read the part number on the old board

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 Jack sewing machine part numbers lookup.

2. Check the generation of the board

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.

3. Compare connectors and voltage

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.

4. Send us a photo before you order

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.

Motherboard, PCB, Control Board and Control Box: What Is the Difference?

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 direct drive servo control board.

Signs Your Sewing Machine PCB Has Failed

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 servo motor problems and error codes and Jack error codes for all models help you tell a board fault from a motor fault.

Sewing Machine Motherboard FAQ

What is the price of a sewing machine motherboard in India?

Main PCB control boards in our catalogue cost between ₹1,500 and ₹4,650, depending on the machine. Jack A2B is ₹2,900, Jack 781G is ₹4,650 and Qi Xing QD8633 is ₹3,100. Display panels and pedal boards cost less, from ₹300. Prices on this page are live catalogue prices and COD is available.

How do I know which PCB fits my sewing machine?

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.

Can I use a universal or generic PCB instead of the original?

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.

How do I know if the PCB is faulty and not the motor?

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.

Are Jack A2B and Jack A2C PCBs the same?

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.

Do you deliver sewing machine motherboards across India with COD?

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.
