Cross-Brand Compatibility

Overview

The D38999/24WE26SN is a MIL-DTL-38999 Series III jam nut receptacle in shell size 17 with insert arrangement E26 carrying 26× #20 socket contacts, in Olive Drab Cadmium finish with Normal keying. Series III is the highest-specification member of the 38999 family: a Tri-Start threaded coupling with an anti-decoupling ratchet, scoop-proof shell-to-shell engagement and a mated IP67 seal. It is the connector specified for airframe, engine-bay, ground-vehicle and naval harnesses that must survive continuous vibration and high mating-cycle counts, and it interchanges on a form, fit and function basis with the Amphenol, TE Deutsch and Souriau part numbers shown above. Airoadcon builds the cross-brand equivalent J599/24WE26SN with QPL-grade materials and free samples for qualification testing.
