Procurement Notes

Verify the specific suffix codes against official datasheets to confirm contact plating and termination type accuracy. Ensure compatibility with mating receptacles regarding shell size and position count. Confirm regulatory compliance status for the intended deployment environment before finalizing procurement orders.

Selection Notes

Select this component when high pin counts are required within standard MIL-DTL-38999 form factors. Evaluate the need for crimp termination capabilities versus solder alternatives. Consider the aluminum shell material properties regarding weight and corrosion resistance relative to other housing options.

Part Context

This part belongs to the JT series of circular connectors manufactured by Amphenol Aerospace. The JT series represents a lightweight, high-performance alternative to heavier military connector families, offering similar electrical performance in a reduced physical footprint. It is widely utilized in aerospace and defense applications requiring reliable signal and power transmission.

Replacement Considerations

Cross-reference with equivalent MIL-DTL-38999 Series III connectors from other manufacturers. Verify that substitute parts match the 56-position layout and shell size 24 dimensions precisely to ensure mechanical fit and electrical continuity.
