Mitsubishi J4-P9M7.5A is a servo drive power board assembly offered for replacement enquiries involving compatible Mitsubishi drive equipment. The photographed assembly combines a main PCB, a raised upper PCB, screw terminal blocks, capacitors and insulated wire links.

The upper PCB carries the full J4-P9M7.5A marking, the number BC386A861G51 and a separate D marking. It is also labelled as the upper board. Keep these identifiers separate from the complete drive model and confirm the required assembly scope before ordering.

J4-P9M7.5A Product Information

Upper PCB vs. Complete Power Board Assembly

BC386A861G51 identifies the photographed upper PCB. A request for this board alone may have a different supply scope from a request for the assembled power section shown. Confirm whether the quotation includes both PCBs, terminal blocks, capacitors, wire links, mounting hardware and the metal-base component.

Terminal Blocks and Internal Connection Layout

The terminal-side photographs show a row of partitioned screw terminals. Other views show the upper-board fixing points, insulated wire routing and tall capacitors. Compare these features, the board outline and mating connectors with the original assembly. Use the exact drive documentation for terminal assignments, tightening requirements and electrical ratings.

J4-P9M7.5A Replacement Checks

Retain the decimal point and A suffix in J4-P9M7.5A. Provide the original drive nameplate and clear photographs of both PCB sides and all identification labels. The model characters alone do not establish the assembly's electrical ratings or compatibility. A qualified technician should check the original fault, power components, wiring and mating connections before replacement.

Follow the drive's power-isolation and capacitor-discharge procedures, verify absence of voltage and use anti-static protection during handling. For a quotation, send the required quantity, preferred condition and delivery country. Actual-unit photographs and testing details can be confirmed before shipment.
