71-433338-55Z

Overview

The 71-433338-55Z is a circular MIL-spec connector manufactured by Amphenol Aerospace Operations. It serves as an alternative designation for the JT06RP-22-55SD(003)(LC) receptacle, complying with MIL-DTL-38999 Series III standards. This component features a size 22 shell with 55 socket positions arranged in a 22-55 insertion configuration. The contacts are designed for crimp termination and utilize gold plating over copper alloy substrates. Rated for 400 VAC and 500 VDC, it supports a current rating of 3 A. The housing is constructed from aluminum with electroless nickel plating, ensuring durability in harsh environments.

Feature Summary

• Complies with MIL-DTL-38999 Series III environmental and performance specifications
• Features a straight wall-mount receptacle design with bayonet coupling mechanism
• Utilizes gold-plated copper alloy contacts for reliable signal transmission
• Constructed with aluminum alloy housing for structural integrity and corrosion resistance

Applications

• Avionics systems requiring high-density interconnects
• Radar and communication equipment installations
• Harsh environment defense applications subject to vibration and humidity
• Ground vehicle and naval electronic subsystems

Procurement Notes

Verify the exact manufacturer part number against the distributor listing, as 71-433338-55Z functions as an alternate identifier for the primary Amphenol part JT06RP-22-55SD(003)(LC). Confirm that the ordering suffix matches the required contact type and termination style. Ensure the supplier provides traceability documentation consistent with military specification requirements. Cross-reference the shell size and position count to guarantee compatibility with mating plugs and panel cutouts before finalizing procurement orders.

Selection Notes

Select this component when a MIL-DTL-38999 Series III compliant receptacle is required for size 22 shells. The 55-position capacity suits high-density wiring needs within constrained spaces. Verify that the crimp termination method aligns with available wire gauge options and tooling. Consider the straight mounting orientation and bayonet lock style for installation constraints. Ensure the voltage and current ratings meet the specific circuit demands of the target application without exceeding limits.

Part Context

This connector belongs to the extensive family of circular MIL-spec interconnects produced by Amphenol Aerospace. These components are engineered for reliability in demanding operational conditions, including extreme temperatures and mechanical stress. The series offers various shell sizes and contact arrangements to support diverse signaling and power distribution requirements across aerospace and defense sectors.

Replacement Considerations

The part number 71-433338-55Z corresponds directly to the Amphenol model JT06RP-22-55SD(003)(LC). Substitution should involve verifying identical MIL-DTL-38999 compliance and physical dimensions. Ensure mating plug compatibility regarding contact arrangement and coupling nut style before replacement.
