71-433338-32S

Overview

The Amphenol Aerospace Operations model 71-433338-32S is a circular MIL-spec connector belonging to the MIL-DTL-38999 series. It functions as a plug with a straight cable mount style and threaded mating interface. The component utilizes a size 22 shell constructed from aluminum alloy material. Internal contact arrangements are defined by standard 22-01 pin configurations, providing 100 positions for signal transmission. Contacts are manufactured from copper alloy and feature gold plating to ensure reliable conductivity and corrosion resistance. The assembly supports crimp termination methods for secure wire attachment. Electrical ratings include a current capacity of 3 A and voltage specifications of 400 VAC and 500 VDC. This interconnect solution is designed for harsh environment defense applications requiring vibration and pressure resistance.

Feature Summary

• Threaded coupling mechanism provides secure connection in high-vibration environments
• Gold-plated copper contacts ensure low insertion loss and durability
• Aluminum shell construction offers lightweight structural integrity
• Crimp termination style facilitates robust wire harness integration

Applications

• Avionics systems in military aircraft
• Naval communication equipment
• Radar system signal distribution
• Missile guidance control interfaces

Procurement Notes

Verify the specific contact arrangement and shell finish against the official datasheet before ordering. Confirm that the crimp tooling matches the contact size requirements. Ensure environmental sealing needs align with the connector's IP rating. Check for any applicable export control restrictions or compliance certifications required for the intended deployment region. Cross-reference the manufacturer part number with legacy equivalents if replacing existing hardware.

Selection Notes

Select this connector when a high-density circular interface is required for board-to-cable connections in rugged settings. The size 22 shell accommodates substantial pin counts within a compact form factor. Gold plating is essential for applications demanding consistent signal integrity over extended operational lifespans. The straight cable mount orientation suits installations where space allows linear routing away from the mounting panel.

Part Context

This component is part of the broader MIL-DTL-38999 family of circular connectors, widely utilized across defense and aerospace sectors. It complements other Amphenol products like the MB3 series rectangular connectors by offering a specialized circular alternative for high-pin-count applications. The 38999 series is known for its miniaturization and performance in extreme conditions, distinguishing it from older MIL-C-5015 designs.

Replacement Considerations

Legacy equivalent part numbers may include 87-433338-32S. Verify compatibility with mating receptacles and housing components. Ensure that the replacement unit meets the same MIL-DTL-38999 specifications regarding contact arrangement and shell size.
