Mitsubishi J3-C20A is a servo amplifier control PCB supplied as a replacement board for compatible Mitsubishi drive assemblies. The photographed board carries the additional identification BC386A471G52 and a MADE IN JAPAN marking.
Mitsubishi Electric's official spare-parts catalogue lists J3-C20A as a printed circuit board for a servo amplifier. For replacement selection, compare the complete board identification, connector layout and original amplifier model. The J3-C20A marking alone does not establish compatibility with every MR-J3 amplifier.

J3-C20A and BC386A471G52 Identification
Use J3-C20A as the main product model and BC386A471G52 as an additional matching reference. The reverse side also shows a J3-C20 base marking. This shorter marking is insufficient for selecting a replacement or establishing interchangeability with J3-C20C or another J3-C20 variant.
Connector Layout and Display Daughterboard
The photographs show two metal-shielded connectors, two black connector housings, a D-sub connector and a brown board-to-board connector. An upright daughterboard carries the digital display. Compare these positions, mounting points and fitted parts with the original assembly, and confirm whether the display daughterboard is included in the quoted supply.
Replacement and Configuration Checks
Send clear photographs of both sides of the original PCB, its labels and the complete servo amplifier nameplate before ordering. Confirm the board version, amplifier specification and any firmware or configuration requirements with a qualified technician. Follow the amplifier maintenance instructions for power isolation, capacitor discharge and anti-static handling during replacement.
