71-528333-04F

Overview

The 71-528333-04F is a circular MIL-spec connector manufactured by Amphenol Aerospace Operations, also identified as JTPQ00RT-12-4SA(003). It belongs to the Series 71 family and complies with MIL-DTL-38999 standards. The component features a Size 12 shell with a straight receptacle mounting style and bayonet coupling mechanism. It utilizes socket contacts and employs crimp termination for wire attachment. The housing is constructed from aluminum alloy with an electroless nickel plating finish. This design ensures reliable performance in demanding environments requiring secure electrical interconnections.

Feature Summary

• Bayonet coupling system provides rapid and secure mating engagement
• Crimp termination method ensures robust mechanical and electrical contact integrity
• Electroless nickel plated aluminum alloy housing offers corrosion resistance

Applications

• Avionics systems
• Military ground equipment
• Marine navigation systems

Procurement Notes

Verify the specific datasheet version for the 71-528333-04F or its equivalent JTPQ00RT-12-4SA(003) to confirm current manufacturing status and compliance certifications. Ensure that the selected cable assembly matches the specified crimp tooling requirements for Size 12 socket contacts. Cross-reference the MIL-DTL-38999 specifications to validate environmental sealing and temperature range suitability for the intended operational conditions.

Selection Notes

Select this component when a Size 12 circular connector with a bayonet lock is required for panel-mounted applications. The straight receptacle configuration suits direct chassis installation. Verify that the socket contact type aligns with the mating plug pin configuration. Consider the electroless nickel finish for general environmental protection rather than high-conductivity gold plating applications.

Part Context

This part falls under the Amphenol Series 71 circular connector line, which adheres to MIL-DTL-38999 specifications. These connectors are engineered for high-density interconnect solutions in aerospace and defense sectors. The Size 12 designation indicates a specific shell size balancing contact count and physical footprint. The product represents a standard industrial-grade solution for ruggedized electronic assemblies.

Replacement Considerations

The part number JTPQ00RT-12-4SA(003) serves as a verified alternative identifier for this component. When substituting, ensure the replacement maintains the same MIL-DTL-38999 compliance and bayonet coupling interface. Verify that the contact orientation and termination method remain compatible with existing cable assemblies.
