Cross-Brand Compatibility

Overview

The D38999/20KA98SN is a MIL-DTL-38999 Series III wall mount receptacle in shell size 9 with insert arrangement A98 carrying 3× #20 socket contacts, in Passivated Stainless Steel finish with N 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 J599/20KA98SN with QPL-grade materials and free samples for qualification testing.
