71-529702-99Z

Overview

The Amphenol Aerospace Operations part number 71-529702-99Z is a circular connector plug classified under the Tri-Start TV series. It features a self-locking mechanism and is constructed with an aluminum shell finished in cadmium with a chromate conversion coating. The connector utilizes a size 25-7 insert arrangement containing 99 positions, specifically configured as 97 signal contacts and 2 coaxial contacts. These contacts are designed for crimp termination and feature gold plating to ensure reliable mating performance.

Feature Summary

• Self-locking coupling mechanism provides secure connection without manual tightening.
• Aluminum alloy housing offers structural integrity with environmental sealing capabilities.
• Gold-plated contacts support low-resistance electrical connections for signal and coaxial lines.

Applications

• Military avionics systems requiring MIL-DTL-38999 Series III compliance
• Harsh environment industrial control interfaces
• Defense communication equipment enclosures

Procurement Notes

Verify the specific suffix codes against the manufacturer's current datasheet to confirm contact configuration and shell finish. Ensure compatibility with mating receptacles regarding thread type and insert arrangement. Confirm that the self-locking interface matches the system design requirements before procurement.

Selection Notes

Select this component when a high-density interconnect solution is required within a compact cylindrical form factor. The self-locking feature simplifies assembly in confined spaces where traditional threaded couplings may be difficult to access. Verify that the operating temperature range aligns with the specific environmental conditions of the installation site.

Part Context

This part belongs to the Tri-Start TV series, which is designed to meet MIL-DTL-38999 Series III specifications. The series is characterized by its lightweight aluminum construction and robust environmental sealing. It serves as a standard interconnect solution for aerospace and defense applications demanding high reliability and durability.

Replacement Considerations

Cross-reference with DigiKey part number 1178-JT08RP-10-99SD(318) for equivalent specifications. Ensure that any substitute maintains the same 99-position insert arrangement and self-locking interface characteristics to guarantee mechanical and electrical compatibility.
