71-529637-01R

Overview

The Amphenol Aerospace Operations part number 71-529637-01R is a circular MIL-spec connector component, specifically identified as the JT00RT-20-1PB(003)(LC) receptacle. It belongs to the JT series and complies with MIL-DTL-38999 Series III standards. The assembly features a size 20 shell with a threaded coupling mechanism and straight panel mount installation. It utilizes solder termination for contact attachment and includes silver-plated copper alloy contacts. The housing is constructed from aluminum alloy with an electroless nickel surface finish, providing robust environmental protection for demanding operational conditions.

Feature Summary

• Complies with MIL-DTL-38999 Series III specifications for high-reliability interconnects
• Features a rugged aluminum alloy housing with electroless nickel plating for corrosion resistance
• Utilizes a threaded coupling ring for secure mating in vibration-prone environments
• Designed for straight panel mount installation with solder termination

Applications

• Avionics systems requiring certified MIL-Spec reliability
• Ground-based military communication equipment
• Industrial instrumentation subject to harsh environmental conditions
• Defense electronics and radar systems

Procurement Notes

Verify that the specific suffix (003)(LC) matches the required contact arrangement and environmental sealing specifications. Confirm compliance with current MIL-DTL-38999 revisions. Ensure the supplier provides traceable documentation for the electroless nickel finish and material certifications. Cross-reference the internal manufacturer code 71-529637-01R with the official datasheet to validate pinout and termination type before procurement.

Selection Notes

Select this component when a Series III circular connector is required for panel-mounted applications. The size 20 shell accommodates specific contact counts suitable for mixed signal or power distribution. The threaded coupling offers superior retention compared to bayonet styles. Verify that the operating temperature range aligns with system requirements and that the silver contact plating is compatible with the mating interface.

Part Context

This part is manufactured by Amphenol Aerospace Operations under the JT product line. It serves as a receptacle variant within the broader family of MIL-DTL-38999 connectors. The designation 71-529637-01R corresponds to the commercial drawing number for the JT00RT-20-1PB(003)(LC) configuration. It represents a standardized solution for aerospace and defense industries requiring rigorous performance standards.

Replacement Considerations

Equivalent parts include MS3122R20-1P and DT01-20S. Verify that substitute components maintain the same MIL-DTL-38999 Series III qualification. Ensure the replacement matches the shell size, thread style, and contact termination method. Check for any changes in environmental sealing ratings or material composition.
