Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure compatibility with required sealing options and contact plating variations. Confirm that the procurement source provides original manufacturer documentation or authorized distributor certification to guarantee authenticity. Cross-reference the full part string including environmental qualifiers to match exact application requirements before finalizing orders.

Selection Notes

Select this connector based on the requirement for a size 18 bayonet-coupled receptacle within the MIL-DTL-38999 Series III family. Ensure the mating interface matches the corresponding plug housing and backshell components. Evaluate environmental sealing needs, such as IP ratings, and verify that the contact configuration aligns with the specific circuit layout requirements of the target assembly design.

Part Context

This component is part of the extensive JT series portfolio from Amphenol Aerospace Operations, which serves critical interconnect needs in the commercial and military aerospace sectors. The series is engineered for reliability under extreme vibration, temperature fluctuations, and moisture exposure. It represents a standardized solution for high-density wiring applications where space constraints and ruggedness are primary design drivers.

Replacement Considerations

Compatible substitutes include equivalent MIL-DTL-38999 Series III connectors from other qualified manufacturers such as TE Connectivity or ITT Cannon, provided they meet the same size 18 bayonet specifications. Verify cross-compatibility of mating interfaces and environmental seals when considering alternative sources.
