Procurement Notes

Verify the exact mating interface and contact orientation against the system schematic before procurement. Confirm that the housing style matches the panel cutout requirements. Ensure compatibility with specified cable assemblies or wire termination methods. Cross-reference the revision level to guarantee interchangeability with existing infrastructure components.

Selection Notes

Select this component based on its specific wall-mount geometry and required pin count. Evaluate the environmental sealing needs against the operational altitude and temperature range. Consider the mechanical retention method suitable for the installation surface. Validate that the contact plating meets the conductivity and wear requirements of the intended circuit.

Part Context

This part belongs to the Amphenol Series 71 family of circular connectors, widely utilized in ruggedized electronic enclosures. The series is characterized by its robust metal construction and reliable locking mechanisms. Components within this lineage are typically specified for critical flight hardware where failure is not an option, distinguishing them from commercial-grade alternatives through rigorous testing protocols.

Replacement Considerations

Direct substitutes must match the shell size, number of contacts, and mounting style. Verify that any alternative maintains the same contact arrangement and polarity. Ensure the replacement meets identical MIL-spec or equivalent military standards for environmental sealing and mechanical strength.
