Procurement Notes

Verify the specific ordering suffix to confirm exact contact arrangements and plating specifications before procurement. Ensure that the selected variant matches the required shell size and mounting style for your application. Cross-reference the manufacturer's datasheet for precise dimensional tolerances and material certifications. Confirm compliance with current export control regulations if applicable. Request official documentation to validate part authenticity and traceability.

Selection Notes

Evaluate the required number of contacts to ensure the 99-position configuration meets system needs without excess bulk. Consider the operating environment to determine if the standard cadmium plating suffices or if alternative finishes are necessary. Assess the cable diameter to select the appropriate strain relief and entry gland options. Verify compatibility with existing mating connectors and receptacles in the assembly. Review thermal and mechanical stress requirements to confirm suitability for the intended operational lifecycle.

Part Context

This component belongs to the MIL-DTL-38999 Series III family of circular connectors, widely used in aerospace and defense industries. The series is known for its small form factor and high density compared to earlier generations. Amphenol Aerospace Operations manufactures this line to meet stringent military specifications for reliability and performance. The 71-series designation typically indicates a plug configuration with specific contact layouts optimized for complex wiring harnesses.

Replacement Considerations

Compatible substitutes include equivalent MIL-DTL-38999 Series III plugs from other qualified manufacturers such as TE Connectivity or LEMO. Ensure that any replacement maintains the same shell size, contact count, and termination type. Verify that the substitute part meets all original military specification requirements for environmental sealing and mechanical strength. Check for cross-reference availability through authorized distributor channels.
