Procurement Notes

Verify the specific datasheet revision and contact arrangement against the official Amphenol documentation before procurement. Ensure that the mating connector counterpart matches the pin/socket configuration and shell size exactly. Confirm environmental sealing requirements align with the intended operational conditions. Cross-reference the manufacturer part number with any applicable military specifications to guarantee compliance with project standards.

Selection Notes

Select this component when a single-position straight cable plug is required within a MIL-DTL-38999 compatible ecosystem. Consider the aluminum construction for weight-sensitive applications where moderate shielding is sufficient. Evaluate the crimp termination method against available assembly tooling capabilities. Ensure the operating temperature range meets the specific mission profile requirements.

Part Context

This part falls under the standard circular connector family produced by Amphenol Aerospace. It complements receptacles and wall-mount variants within the same shell size series. The design supports high-density interconnect needs in aerospace and defense sectors. It serves as a critical interface point between cable assemblies and panel-mounted hardware.

Replacement Considerations

Check for cross-referenced parts such as PT08CP-22-21P(LC) which may share similar form factors. Verify compatibility with existing mating connectors before substitution. Ensure that any alternative maintains the same electrical ratings and mechanical dimensions.
