71-432653-34S

Overview

The Amphenol Aerospace Operations part number 71-432653-34S is a circular MIL-spec connector assembly. It functions as a receptacle with a wall mount installation style and straight orientation. The unit features a size 22 shell constructed from aluminum with cadmium plating. Internal contacts are silver-plated copper alloy sockets arranged in a 22-21 insertion pattern for 3 positions. Termination is achieved via solder connections. This component complies with the MIL-DTL-22992 standard.

Feature Summary

• Wall-mount receptacle design for panel integration
• Threaded coupling mechanism for secure engagement
• Cadmium-plated aluminum housing for corrosion resistance
• Silver-plated copper alloy socket contacts

Applications

• Avionics systems
• Defense communication equipment
• Radar systems
• Naval instrumentation

Procurement Notes

Verify the manufacturer date code and lot traceability against the original equipment manufacturer specifications. Confirm that the physical condition of the contacts shows no signs of oxidation or mechanical damage. Ensure the packaging integrity remains sealed to prevent contamination prior to installation. Cross-reference the specific suffix codes to confirm exact mating compatibility with existing cable assemblies.

Selection Notes

Select this component when a MIL-DTL-22992 compliant wall-mount receptacle is required. The size 22 shell accommodates specific pin-and-socket configurations suitable for moderate current applications. Verify that the solder termination method aligns with the available board space and thermal constraints of the host system. Ensure the threaded coupling style matches the mating connector interface requirements.

Part Context

This part belongs to the Amphenol 22992 series, which provides high-performance interconnect solutions for harsh environments. These connectors are engineered to withstand vibration, pressure, humidity, and severe temperature changes typical in aerospace and defense sectors. The series offers reliable signal transmission for critical avionics and control systems.

Replacement Considerations

The part MS17343C22C21S is a confirmed equivalent designation for this component. The alternative part number 88-456022-21S also serves as a valid substitute. Verify dimensional tolerances and contact alignment before substituting.
