71-529636-53F

Overview

The 71-529636-53F is a circular MIL-spec receptacle connector manufactured by Amphenol Aerospace Operations. It complies with the MIL-DTL-38999 series standards and features a bayonet coupling style for secure mating. The unit utilizes an aluminum shell with electroless nickel plating to provide environmental protection. Designed for wall mount installation, this component accommodates 53 positions using socket contacts. It supports crimp termination methods for reliable wire attachment.

Feature Summary

• Bayonet coupling mechanism ensures rapid and secure connection engagement
• Aluminum alloy housing provides structural integrity and corrosion resistance
• Wall mount configuration facilitates direct panel integration
• Socket contact arrangement enables compatible pin mating

Applications

• Avionics systems requiring MIL-DTL-38999 compliance
• Military communication equipment interfaces
• Radar system signal distribution panels
• Test and measurement instrument rear panels

Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm exact contact plating, seal options, and mounting hardware configurations. Ensure the ordering part number matches the required shell size and position count precisely. Request current availability status directly from authorized distributors as stock levels fluctuate. Confirm that the intended application environment aligns with the connector's specified temperature and humidity ratings before finalizing procurement.

Selection Notes

Select this component when a robust circular interface meeting military specifications is required for fixed installations. The bayonet style offers faster engagement compared to threaded alternatives while maintaining high vibration resistance. Evaluate the need for wall mount versus bulkhead orientation based on chassis design constraints. Consider the aluminum construction weight benefits against potential electromagnetic interference shielding requirements for sensitive circuits.

Part Context

This model belongs to the extensive family of circular connectors defined by MIL-DTL-38999 standards. These connectors are widely utilized across aerospace and defense sectors due to their standardized dimensions and interchangeability. The 71-529636-53F represents a specific configuration within this lineage, characterized by its particular shell size and contact density suitable for complex signal routing applications in harsh environments.

Replacement Considerations

Compatible substitutes include equivalent MIL-DTL-38999 Series III receptacles from other qualified manufacturers such as LEMO or Glenair. Verify that any replacement maintains identical shell size, position count, and bayonet coupling geometry. Cross-reference contact arrangements to ensure pin-to-pin compatibility with existing cable assemblies without redesigning harnesses.
