Mitsubishi K-Type Escalator Module Board J631726B000G01 J631726B000G51

Mitsubishi K-Type Escalator Module Board J631726B000G01 / J631726B000G51 is used in Mitsubishi K-type escalator electrical control and drive cabinet applications.

In the escalator spare parts market, this board may be described under several different names, including Mitsubishi escalator PCB, K-type escalator module board, module drive board, capacitor board, or escalator control cabinet PCB. Because the market naming is not fully consistent, the exact board model printed on the original PCB should be used as the main confirmation reference.

This page covers the following model references:

• J631726B000G01
• J631726B000G51
• Mitsubishi K-Type Escalator Module Board
• Mitsubishi Escalator PCB Board
• Mitsubishi Escalator Module Drive Board
• Mitsubishi Escalator Capacitor Board

Public product listings show J631726B000G51 as a Mitsubishi escalator PCB, and trade data also records J631726B000G51 as a P.C. board for Mitsubishi escalator spare parts. Domestic market listings also describe J631726B000G01 as a Mitsubishi K-type escalator module drive board / capacitor board.

Why This Board Should Be Confirmed Carefully

For Mitsubishi K-type escalators, several PCB boards may be installed in the same control cabinet or drive cabinet area.

A technician may call this part:

• Module board
• Drive board
• Capacitor board
• Escalator PCB
• Control cabinet board

These names may refer to the same board area, but they are not enough for accurate replacement. The safest confirmation method is to match the old board model number and compare the PCB layout.

Before ordering, buyers should check:

• Complete J631726B000G01 or J631726B000G51 marking
• Front and back photos of the PCB
• Connector quantity and direction
• Capacitor or module area on the board
• Installation position inside the escalator cabinet
• Nearby board numbers if visible
• Existing escalator fault description

This is especially important because other Mitsubishi K-type escalator boards, such as J631720B000G01 / G02 / G51 / G52 and J631722B000G01 / G02 / G51 / G52, also appear in the spare parts market as K-type escalator board or control PCB references. These models should be treated as related K-type escalator PCB references, not direct replacements for J631726B000G01 / G51.

Practical Maintenance Notes

J631726B000G01 / J631726B000G51 may be inspected when the escalator control cabinet shows abnormal drive response, module-related fault indication, capacitor board damage, visible PCB failure, or unstable control behavior.

Before replacing the board, technicians usually check the surrounding cabinet condition, including power input, wiring terminals, connected modules, fuse or protection circuit, cabinet ventilation, and signs of overheating.

If the old board was damaged by an external short circuit, unstable power, damaged module, or wiring fault, replacing only the PCB may cause repeated failure. For this reason, old-board photos and cabinet photos are very useful before shipment.

FAQ

Is J631726B000G01 the same as J631726B000G51?
They appear as closely related Mitsubishi escalator PCB references, but they should not be treated as automatically interchangeable. The original board label and connector layout should be confirmed before replacement.

Is this a control board or capacitor board?
Market descriptions are not fully consistent. Some sources call it an escalator PCB or module board, while some listings describe J631726B000G01 as a K-type escalator module drive board / capacitor board. The actual function should be confirmed from the old board and cabinet position.

What photos are needed before ordering?
Front and back PCB photos, the printed model number, connector area, capacitor or module area, and installation position inside the escalator cabinet are recommended.
