RM121B-3E2 Control PCB Identification

The photographed Mitsubishi PCB carries the fixed marking RM121B- and the configuration suffix 3E2. Its complete board identification is therefore RM121B-3E2, with PCB number BC886A099G51.

The separate A label visible beside the board marking is not part of the model number. The board should not be identified as RM121B-3E2A, RM121B-3A or RM121B-302.

RM121B, RM121 and RM121B-3 Search Variations

Customers may search for this PCB as RM121B, RM121B-3E2, RM121, RM121B-3, RM121B3, RM121B3E2, RM121B-3 E2 or BC886A099G51. These variations cover shortened, spaced and punctuation-free searches.

RM121B-3 is commonly used as a shortened market reference, but it omits the E2 suffix shown on this board. RM121B-3E2 and BC886A099G51 should be used for the final replacement check.

Compatibility Checks Before Replacement

Compare the complete model marking, PCB number, connectors, component layout and every configuration or revision label. The separate equipment or drive-unit nameplate should also be checked because the internal PCB marking alone does not confirm the complete host model.

RM121B-3E2 must not be treated as interchangeable with RM113B-3, RN113A-NS-E or another board carrying a different BC number. Similar RM or RN references do not establish replacement compatibility.
