Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix to confirm contact plating and termination style, as variations exist within the R Series. Confirm that the required polarization guide set matches the mating plug configuration. Ensure the vertical mounting orientation aligns with the PCB layout constraints. Cross-reference the manufacturer datasheet to validate environmental ratings against application requirements before finalizing procurement.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a vertical, multi-row MIL-Spec receptacle is required for board-level integration. The 23-position capacity suits moderate-density interconnect needs. Gold plating ensures low contact resistance for sensitive signals. Verify that the 1.91 mm pitch accommodates the available PCB trace spacing. Consider the thermal limits of the PPS housing if high-temperature soldering or operation is anticipated.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the AirBorn R Series, a line of rectangular connectors known for high density and reliability. The series is widely used in aerospace and defense sectors where strict adherence to MIL-DTL-55302 standards is mandatory. The RM322 prefix indicates a specific housing size and row configuration within the broader product family.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 23-position count, 3-row layout, and 1.91 mm pitch. Compatible alternatives include other MIL-DTL-55302 compliant receptacles from qualified manufacturers. Verify that any replacement maintains the same vertical orientation and gold-plated contact specifications to ensure electrical continuity.
