Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix code against official Molex/AirBorn documentation to confirm termination type and jackset configuration. Ensure compatibility with existing PCB layouts regarding tail length and row spacing. Confirm RoHS status as indicated in current datasheets, as some variants may not be compliant. Cross-reference part numbers carefully to avoid confusion with similar R Series receptacles differing only in circuit count or mounting features.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a high-density, vertically mounted MIL-spec receptacle is required. The 47-position capacity suits applications needing substantial I/O in a compact footprint. Verify that the through-hole termination method aligns with assembly capabilities. Consider the fixed jackset design for secure mating in vibration-prone environments. Ensure the operating temperature range meets system environmental requirements.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the AirBorn R Series, a line of rectangular connectors known for meeting stringent military standards. The series offers various configurations including plugs and receptacles in different row counts and orientations. The RM342 prefix typically denotes a specific housing style within the R Series family, characterized by its plastic body and board-mount capability.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the MIL-DTL-55302 specification, 47-position count, 3-row layout, and 1.91 mm pitch. Verify identical termination style and contact plating. Equivalent parts from other manufacturers must meet the same electrical and mechanical parameters.
