Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix designation against official Molex/AirBorn documentation to confirm exact row configuration and termination style. Ensure compatibility with corresponding plug counterparts in the W Series. Confirm environmental sealing requirements if applicable, as standard MIL-DTL-55302 connectors may require additional gaskets for IP ratings. Validate that the solder cup termination matches the wire gauge specifications in the system design.

Headers, Receptacles, Female Sockets Selection Notes

Select this part when a high-density, ruggedized interconnect solution is required for fixed or semi-permanent cable assemblies. The 2.54 mm pitch allows for compact circuit board or cable management while maintaining robust mechanical integrity. Consider the free-hanging mounting style for applications where the connector is attached directly to the cable rather than a panel. Ensure the mating plug features compatible push-pull latching to maintain the intended mechanical retention.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the AirBorn W Series, a family of high-reliability connectors designed to meet MIL-DTL-55302 standards. The series is characterized by its modular row options and durable construction suitable for harsh environments. As a Molex company product, AirBorn connectors are widely specified in defense and aerospace sectors for their proven track record in critical signal and power transmission applications.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct replacements must adhere to MIL-DTL-55302 specifications. Verify pin-to-pin compatibility with existing mating plugs. Cross-reference with other manufacturers' MIL-DTL-55302 equivalents only if form, fit, and function data sheets confirm identical electrical and mechanical parameters.
