Procurement Notes

Verify the exact suffix codes against official manufacturer documentation to ensure correct plating and environmental ratings. Confirm that the supplier provides traceability certificates matching the specific lot numbers. Cross-reference the commercial code with the military specification to validate compatibility with existing panel cutouts and mating connectors before finalizing procurement orders.

Selection Notes

Select this component when a Series II circular connector is required for box-mounted applications. Ensure the design accommodates the size 20 shell dimensions and 39-position layout. Verify that the crimp tooling matches the specified contact sizes. Consider the aluminum housing material for weight-sensitive aerospace applications where anodic coating provides sufficient corrosion resistance.

Part Context

This component belongs to the Amphenol 38999 Aluminum series of circular connectors. It represents a standard interface solution within the MIL-DTL-38999 family, widely adopted in defense and aerospace sectors.
