Procurement Notes

Verify the exact datasheet version and current manufacturing status directly with Amphenol Aerospace Operations or authorized distributors. Confirm that the bayonet receptacle configuration matches your system requirements. Ensure compatibility with corresponding plug assemblies regarding contact type and shell size. Request official documentation to validate EREL certification and material specifications before integration into critical designs.

Selection Notes

Select this component when a durable, MIL-spec circular receptacle is required for wall mounting. The aluminum construction offers weight advantages over steel alternatives while maintaining structural integrity. The bayonet interface suits applications needing frequent connection cycles. Verify that the specific contact arrangement and current ratings align with the circuit design needs. Consider environmental sealing requirements if operating in extreme conditions beyond standard housing capabilities.

Part Context

This part belongs to the broader family of MIL-DTL-83723 connectors, widely used in defense and aerospace sectors. Amphenol Aerospace Operations produces these components to meet stringent reliability standards. The 71-series designation typically indicates specific shell styles and coupling methods within the manufacturer's catalog. These connectors are integral to ensuring signal and power transmission integrity in high-vibration and temperature-variable environments typical of aviation platforms.

Replacement Considerations

Cross-reference with other MIL-DTL-83723 III compliant receptacles from different manufacturers if supply constraints exist. Ensure identical shell size, contact count, and bayonet coupling geometry for direct substitution. Verify that alternative parts maintain the same EREL qualification level and material specifications to preserve system performance and regulatory compliance.
