Procurement Notes

Verify the specific suffix codes against official datasheets to confirm exact contact arrangements and environmental sealing ratings. Ensure compatibility with mating plugs regarding shell size and keying options. Confirm that the crimp tooling matches the specified contact sizes. Cross-reference manufacturer part numbers with legacy equivalents to prevent procurement errors during system upgrades or replacements.

Selection Notes

Select this component when a high-density circular connector is required for panel mounting applications. The size 20 shell accommodates 39 positions, balancing space constraints with connectivity needs. Verify that the operating environment aligns with the material specifications of the aluminum housing and gold contacts. Consider the bayonet lock requirement for quick engagement cycles versus screw-thread alternatives.

Part Context

This part belongs to the extensive 38999 series of circular connectors manufactured by Amphenol Aerospace. The series is widely recognized for its interchangeability with other manufacturers' products meeting the same MIL-DTL-38999 standards. The 71- prefix typically denotes specific commercial or military grade variations within the broader product line, emphasizing standardized dimensions and performance characteristics.

Replacement Considerations

Cross-reference with legacy part number 88-528267-39W for potential functional equivalence. Verify dimensional compatibility and electrical ratings before substituting. Ensure that any alternative source meets the original MIL-DTL-38999 specifications to maintain system integrity and certification requirements.
