Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix codes against official datasheets to confirm termination type and plating. Ensure compatibility with mating plugs regarding row spacing and contact gender. Confirm RoHS status if required, as some variants may not be compliant. Cross-reference manufacturer part numbers to avoid substitution errors.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when MIL-DTL-55302 compliance is mandatory for the application. Choose based on the need for 40-position density in a dual-row configuration. Consider the through-hole mounting style for robust mechanical retention. Evaluate the operating temperature range requirements against the PPS material limits.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the AirBorn R Series, designed for high-reliability interconnect solutions. The series is widely used in aerospace and defense sectors where vibration resistance and environmental sealing are critical. The R Series maintains strict dimensional tolerances to ensure interchangeability with legacy MIL-spec designs.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible substitutes include other MIL-DTL-55302 connectors with matching 40-position dual-row layouts. Verify that alternative parts maintain the same 0.075-inch pitch and through-hole termination style. Ensure mating interface dimensions align perfectly to prevent connection failure.
