Mitsubishi Drive Board P203794B000G11 G01

Mitsubishi Drive Board P203794B000G11 / P203794B000G01 is a drive-related PCB board used in Mitsubishi elevator control cabinet and inverter drive applications.

This board is usually requested by the printed PCB number rather than by the complete elevator model. In the elevator spare parts market, customers may describe it as a Mitsubishi elevator drive board, elevator PCB drive board, LEHY-III drive board, drive control PCB, or inverter cabinet PCB.

For this product, the key references are:

• P203794B000G11
• P203794B000G01
• P203772B000G21

These numbers should be used for search and quotation confirmation. However, the final replacement should still be confirmed by the original board label, connector layout, and drive cabinet configuration.

Why G01 and G11 Should Be Checked Carefully

The suffix at the end of a Mitsubishi PCB number may indicate a different board version, production revision, or application configuration.

A board marked P203794B000G01 may look similar to P203794B000G11, but the connector position, component layout, or cabinet wiring requirement may not be exactly the same.

For this reason, maintenance teams usually do not confirm this type of board only by appearance. A clear photo of the old PCB label is the safest starting point.

Photos Needed for Confirmation

For accurate supply, please provide:

• Full front photo of the PCB
• Full back photo of the PCB
• Close-up photo of the P203794B000G11 or P203794B000G01 label
• Connector area photo
• Drive cabinet installation photo
• Nearby inverter or module board photo if available

If the board is installed in a Mitsubishi LEHY-III elevator system, please mention this during inquiry. It helps confirm whether the required board is P203794B000G11, P203794B000G01, P203772B000G21, or another related Mitsubishi drive PCB.

Practical Replacement Notes

This board is part of the elevator drive cabinet environment, so replacement should be handled carefully.

Before installing a replacement board, technicians usually check:

• Cabinet power supply condition
• Inverter or drive module condition
• Connector oxidation
• Wiring terminals
• Fuse or protection circuit
• Cooling condition inside the cabinet
• Signs of overheating or short circuit

If the original board was damaged by unstable cabinet power, IGBT/module failure, wiring short circuit, or poor cooling, replacing only the PCB may cause the new board to fail again.

Supply Reminder

P203794B000G11 / G01 should be matched by the original PCB number first, then by the connector layout and drive cabinet position.

For overseas buyers, sending complete old-board photos before ordering can reduce the risk of wrong supply and shorten confirmation time.
