71-432591-02P

Overview

The Amphenol Aerospace Operations model 71-432591-02P is a circular connector receptacle belonging to the MIL-DTL-38999 Series III family. It features a size 22 shell with a C (Crimp) coupling method and a straight cable exit orientation. The component utilizes a non-environmental contact arrangement designated as 22-02, which supports two signal contacts. These contacts are specified as size 20 crimp type, designed for reliable electrical interconnection in demanding aerospace applications requiring robust mechanical interfaces.

Feature Summary

• MIL-DTL-38999 Series III compliance ensuring rigorous military specification adherence
• Size 22 shell configuration optimized for compact signal routing
• Crimp termination method providing secure and durable contact attachment

• Radar and navigation subsystems
• Harsh environment control instrumentation

Procurement Notes

Verify that the specific order matches the exact shell size, coupling style, and contact arrangement defined in the official datasheet. Confirm material specifications and plating requirements align with the project's environmental standards. Ensure compatibility with mating plugs regarding keying and contact types before procurement.

Selection Notes

Select this component when a MIL-DTL-38999 Series III standard is required for space-constrained signal applications. The size 22 shell offers a balance of density and durability. Verify that the crimp contact termination suits the available wire gauge and assembly tools. Consider the straight exit orientation for panel mounting constraints.

Part Context

This receptacle is part of the extensive MIL-DTL-38999 connector portfolio from Amphenol Aerospace Operations. The Series III designation indicates a high-density variant within the broader circular connector family. It serves as a critical interface component in defense and aerospace platforms where reliability under vibration and temperature extremes is mandatory.

Replacement Considerations

Direct replacements must match the MIL-DTL-38999 Series III standard, size 22 shell, and C coupling style. Verify identical contact arrangements and pin-out configurations to ensure functional interchangeability without redesigning mating interfaces or harnesses.
