Procurement Notes

Verify the specific suffix codes against official Amphenol documentation to ensure correct contact arrangement and environmental sealing options. Confirm that the crimp tooling matches the specified contact size requirements. Cross-reference the MIL-DTL-83723 Series III designation with the latest revision levels to guarantee compliance with current military specifications before finalizing procurement orders.

Selection Notes

Select this model when a high-density 55-position interface is required for wall-mounted applications. Ensure the system environment supports the thermal and mechanical characteristics of aluminum housings. Verify that the bayonet locking style aligns with the mating plug's operational requirements. Consider the 7.5 A current rating relative to the total pin count and duty cycle to prevent overheating during continuous operation.

Part Context

This component belongs to the MIL-DTL-83723 Series III family of circular connectors, widely used in defense and aerospace sectors. It represents a standard solution for robust interconnect needs where vibration resistance and environmental sealing are critical. The series provides a modular approach to connector selection, allowing for various shell sizes and contact arrangements.

Replacement Considerations

Compatible substitutes include MS3471L22-55S and M83723/71R2255N. Verify dimensional compatibility and contact configuration before substitution. Ensure the replacement part meets the same MIL-DTL-83723 Series III specification to maintain system integrity.
