71-529701-98R

Overview

The Amphenol Aerospace Operations part number 71-529701-98R corresponds to the JT08RP-8-98PB(318) circular connector. This is a MIL-DTL-38999 Series III plug with a self-locking mechanism, designed for socket-type contacts using crimp termination. The assembly features a 99-position configuration (comprising 97 signal pins and 2 coaxial contacts) within a shell size 25-7 housing. Constructed from aluminum alloy with a cadmium finish, it provides environmental sealing and shielding capabilities. Rated for 400VAC/500VDC operation and capable of handling up to 65A current, it functions reliably across a temperature range of -65°C to +175°C.

Feature Summary

• Self-locking coupling mechanism ensures secure connection in high-vibration environments
• Integrated shielding provides electromagnetic interference protection
• Environmental sealing design offers resistance to moisture and contaminants
• Crimp termination method supports reliable electrical contact stability

Applications

• Military avionics systems requiring MIL-DTL-38999 compliance
• Harsh environment defense communication equipment
• Naval and ground vehicle electronic assemblies
• Radar and missile system interconnects

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm exact contact arrangements and plating specifications. Ensure compatibility with mating receptacles regarding shell size and pinout configuration. Confirm that the self-locking feature aligns with the mechanical constraints of the installation panel. Cross-reference the environmental sealing requirements with the operational conditions of the target application to ensure adequate performance.

Selection Notes

Select this component when a high-density circular connector with self-locking capability is required for shielded applications. The 99-position layout suits complex signal routing needs. Verify that the operating voltage and current ratings meet the circuit demands. Consider the thermal range limits during selection for extreme temperature deployments. Ensure the crimp tooling matches the specified contact types for proper assembly.

Part Context

This connector belongs to the Tri-Start series, characterized by its self-locking interface which simplifies mating procedures compared to traditional threaded couplings. It falls under the MIL-DTL-38999 Series III classification, indicating a lightweight, high-density design suitable for modern aerospace and defense platforms where space and weight are critical factors.

Replacement Considerations

Direct replacements must match the MIL-DTL-38999 Series III standard, shell size 25-7, and 99-position configuration. Verify that substitute parts maintain the same self-locking mechanism and shielding characteristics to ensure interchangeability without modifying the host enclosure or wiring harness.
