71-433338-02X

Overview

The Amphenol Aerospace Operations part number 71-433338-02X is a circular MIL-specification plug connector belonging to the 38999 Aluminum series. It features a straight cable-mount installation style with a size 22 shell and utilizes a threaded mating interface. The connector supports 100 positions using male pin contacts arranged in insertion configuration 22-01. Contacts are crimped, gold-plated copper alloy components rated for 3 A current at 400 VAC or 500 VDC. This component serves as an alternative designation for JT06RP-22-1PA(LC) and 1178-JT06RP-22-2SC(003)(LC).

Feature Summary

• Provides high-density interconnect capability with 100 positions within a size 22 aluminum shell.
• Ensures reliable signal transmission through gold-plated copper alloy crimp contacts.
• Offers secure mechanical coupling via a threaded mating interface on a straight cable mount.

Applications

• Harsh environment defense applications requiring vibration resistance.
• Avionics systems operating under severe temperature changes.
• Naval and ground vehicle communication equipment.
• Radar systems and missile guidance electronics.

Procurement Notes

Verify the specific suffix and insertion arrangement against the original design specification before procurement. Confirm that the supplier provides traceability documentation for the gold plating and material composition. Ensure the crimp tooling matches the contact size requirements for the 100-position assembly. Cross-reference the part number alias to prevent ordering errors during replacement scenarios.

Selection Notes

Select this connector when a high-pin-count circular interface is required for cable-mounted applications. The aluminum shell offers weight savings compared to steel alternatives while maintaining structural integrity. The threaded coupling provides superior retention strength compared to bayonet styles. Verify that the 3 A per contact rating meets the circuit load requirements for all 100 channels simultaneously.

Part Context

This component belongs to the Amphenol 38999 series of circular connectors, which are designed for military and aerospace environments. The series is known for its small size and light weight. The 71-433338-02X designation specifically identifies a plug variant with a straight orientation. It is functionally equivalent to other manufacturers' equivalents meeting MIL-DTL-38999 standards.

Replacement Considerations

JT06RP-22-1PA(LC) is a confirmed substitute part number. 1178-JT06RP-22-2SC(003)(LC) is also listed as an alias. Verify compatibility with existing receptacles before implementation.
