Mitsubishi RM165C-SP-M is a spindle drive power / driver PCB assembly offered for replacement enquiries involving compatible Mitsubishi drive equipment. The photographed board has an extended profile with a transformer, electrolytic capacitors, heat sinks and multipin connectors.

The complete marking on this unit is RM165C-SP-M, shortened to RM165C-SP in this enquiry. Its additional PCB number is BC886A021G51, with a separate A marking beside the number. Retain the final M suffix when matching the replacement.

RM165C-SP-M Product Information

RM165C-SP vs. RM165C-SP-M Identification

For the photographed unit, RM165C-SP is a shortened reference; the full board marking includes -M. Compare RM165C-SP-M, BC886A021G51, the separate A marking and all other labels with the original assembly. A board with a different suffix or revision requires its own compatibility check.

Transformer Section and Connector Layout

One end of the populated board carries the transformer, tall capacitors and heat sinks. The extended section carries long black and white multipin connectors and smaller components. Compare the connector keying, plated connection positions, PCB outline and component clearance with the original board. Visible P, N, BA1 and FG labels should be checked against the exact drive documentation for wiring and electrical requirements.

Replacement Scope and Installation Checks

Confirm that the quotation covers the populated PCB and the fitted components shown. Send the complete drive nameplate, photographs of both sides of the original board and details of the fault. A qualified technician should check the mating connections, wiring and associated power components before installation.

The PCB carries a high-voltage caution label. Follow the drive's power-isolation and capacitor-discharge procedures, verify absence of voltage and use anti-static protection when handling the board. Provide the required quantity, preferred condition and delivery country for a quotation; actual-unit photographs and testing details can be confirmed before shipment.
