Mitsubishi RN481B-SP-160E is a drive power / interface PCB assembly offered for replacement matching. The photographed board carries BC886A145G51 identification and includes transformers, resistor assemblies, a blue LEM current sensor, power connection pads and board-to-board connectors.

An additional EM label is visible in the model-marking line. Include clear photos of this label and the complete model markings when requesting a replacement.

RN481B-SP-160E Product Information

Product Scope

This listing covers the populated circuit board assembly shown in the photos. Multiple connector rows, copper connection pads, white resistor assemblies and transformers provide useful comparison points. Confirm which fitted components, spacers and mounting hardware are included in the quotation.

Model and Board Identification

Match RN481B-SP-160E, the additional EM label and BC886A145G51 against the original board. Mitsubishi Electric Corporation and Made in Japan markings are visible. Keep the complete identification together rather than selecting by the RN481 base marking alone.

Compare both sides of the PCB, including connector orientation, the J2 connector area, mounting posts and power-pad locations. Similar outlines or shared base markings do not by themselves establish interchangeability.

Fitment Confirmation

Send the complete drive nameplate and clear photos of the original PCB and its labels. Confirm the full variant, revision, fitted components, connector keying and installation clearance. Verify the required drive specification with the original equipment before ordering.

Have a qualified technician follow the exact drive instructions for power isolation, capacitor discharge and board replacement. Confirm the testing scope for the quoted assembly; static product photos do not establish operational test results.

For a quotation, provide the required quantity, preferred condition and delivery country. Actual-unit photos, supply scope, a pre-shipment test video and dispatch timing can be confirmed before shipment.
