71-432479-19P

Overview

The Amphenol Aerospace Operations part number 71-432479-19P is a circular MIL-spec connector plug. It features a size 14 shell with a straight orientation and threaded mating interface. The component utilizes a 19-position arrangement with male pin contacts. These contacts are constructed from copper alloy and feature silver plating for conductivity. The termination method is solder, designed for cable installation. The housing is made of aluminum with cadmium electroplating for corrosion resistance. This connector complies with the MIL-DTL-26482 Series I standard.

Feature Summary

• Threaded coupling mechanism ensures secure connection in high-vibration environments
• Silver-plated copper alloy contacts provide reliable electrical performance
• Cadmium-plated aluminum shell offers structural durability and corrosion protection

Applications

• Avionics systems
• Aircraft power distribution
• Military instrumentation

Procurement Notes

Verify the specific datasheet revision and material certifications against the manufacturing batch. Confirm that the silver plating thickness meets the required environmental specifications for the intended operational life. Ensure compatibility with the corresponding receptacle housing and seal assembly to maintain the designated ingress protection rating during integration.

Selection Notes

Select this component when a MIL-DTL-26482 Series I compliant plug is required for size 14 applications. The solder termination style necessitates compatible wire gauge preparation. Verify that the operating temperature range aligns with the silver plating and aluminum substrate characteristics. Ensure the mating receptacle shares the same shell size and contact arrangement code.

Part Context

This part belongs to the Amphenol MIL-DTL-26482 Series I product line, which provides compact circular connectors for demanding aerospace and defense applications. The series is characterized by its lightweight aluminum construction and robust sealing capabilities. Part numbers in this family typically follow a standardized coding system indicating shell size, contact type, and arrangement.

Replacement Considerations
