71-529706-53E

Overview

The Amphenol Aerospace Operations part number 71-529706-53E is a circular MIL-spec connector receptacle, specifically identified as the JT08RP-18-53PA(318) variant. It features 53 socket contacts arranged in an 18-53 insertion pattern within a size 18 shell. The component utilizes a bayonet coupling mechanism and is designed for wall mount installation. Contact termination is achieved via crimping, with gold plating applied to the contact interfaces. The housing is constructed from aluminum alloy and finished with cadmium plating for environmental protection.

Feature Summary

• Bayonet locking system ensures secure mating and rapid connection/disconnection cycles.
• Crimp termination method supports reliable wire harness integration.
• Gold-plated contacts provide corrosion resistance and stable signal transmission.
• Aluminum alloy housing offers structural durability in harsh environments.

Applications

• Avionics systems requiring MIL-DTL-38999 Series II compliance
• Aircraft power distribution networks
• Military instrumentation and control panels

Procurement Notes

Verify the specific suffix (318) against the manufacturer's current datasheet to confirm material specifications and environmental ratings. Ensure compatibility with corresponding plug housings and contact kits. Cross-reference the commercial part number 71-529706-53E with the military designation JT08RP-18-53PA(318) to validate exact configuration requirements before procurement.

Selection Notes

Select this component when a 53-position circular connector with bayonet coupling is required. Confirm that the application environment aligns with the operating temperature range specified in the official datasheet. Verify that the crimp tooling matches the contact size and type. Ensure the mounting hole dimensions correspond to the size 18 flange specifications.

Part Context

This component belongs to the JT08 series of circular connectors manufactured by Amphenol Aerospace Operations. It adheres to the MIL-DTL-38999 Series II standard, which defines performance and interchangeability requirements for high-density interconnects used in aerospace and defense applications. The series is known for its robust construction and reliability under vibration and shock conditions.

Replacement Considerations

Compatible substitutes include other manufacturers' MIL-DTL-38999 Series II connectors with identical shell size, contact count, and coupling style. Verify dimensional drawings and contact placement patterns to ensure mechanical interchangeability without modification to existing panel cutouts or wiring harnesses.
