Mitsubishi Drive Board P203726B001G01

Mitsubishi Drive Board P203726B001G01 is a drive-related PCB board used in Mitsubishi elevator systems, especially in applications connected with IGBT driver module control.

This board is commonly identified in the elevator spare parts market as:

• P203726B001G01
• Mitsubishi Elevator Drive Board
• Mitsubishi Elevator IGBT Driver Module Board
• Mitsubishi LEHY-III-3 Elevator PCB
• Mitsubishi Elevator Driver PCB

For this product, the printed board number P203726B001G01 should be the main reference for replacement. Public supplier information describes it as a Mitsubishi LEHY-III-3 elevator IGBT driver module board PCB, so it should be treated as a drive cabinet board rather than a general control board.

In actual spare parts supply, this type of board is usually not ordered by elevator model alone. Most buyers provide a photo of the old PCB, because the same elevator series may use different drive cabinet boards depending on the system configuration and production version.

A technician checking this board normally pays attention to:

• the complete P203726B001G01 marking
• connector quantity and direction
• drive cabinet installation position
• IGBT module connection area
• visible burn marks or component damage
• board revision and mounting holes
• surrounding drive circuit condition

This is important because drive boards and IGBT-related boards are sensitive to external faults. If the original board was damaged by an IGBT module problem, unstable cabinet power, wiring short circuit, or cooling failure, replacing only the PCB may not solve the problem.

For replacement confirmation, please provide clear front and back photos of the original board. A close-up photo of the label area and connector side is especially useful. If possible, also provide a photo of the drive cabinet where the board is installed.

Before installation, the related drive circuit should be checked carefully. The maintenance team should confirm the condition of the IGBT module, cooling fan, wiring terminals, fuse or protection circuit, and cabinet power supply. This helps reduce the risk of damaging the replacement board after installation.

P203726B001G01 is suitable for buyers who need a Mitsubishi elevator drive PCB replacement based on the original board number. If the old board marking is unclear, photos of the complete drive cabinet and nearby PCB boards can help confirm whether this is the correct Mitsubishi drive board.
