Straight Plug, 16 × #16 Socket, Shell 21, Olive Drab — MIL-DTL-38999 Series III

Specifications

Overview

The D38999/26WG16SN is the straight plug member of the MIL-DTL-38999 Series III family, carrying 16 × #16 socket contacts in a shell size 21 body with insert arrangement G16. Series III is the tri-start threaded generation: a quarter turn with a ratchet anti-decoupling mechanism replaces the finer-thread coupling of Series I and II, which is what makes it vibration-tolerant enough for airframe and engine-bay mounting.

Each #16 contact is rated 13 A, so this arrangement is a power/signal mixed connector rather than a high-density signal part. Plating class W is olive drab cadmium over nickel — nominally 500 hours of salt spray, the standard choice for general airframe and ground-vehicle environments rather than the electroless-nickel (class F) plating used where non-reflective grey is preferred.

Airoadcon builds the same MIL-DTL-38999 Series III QPL configuration under the J599 prefix; the part is form, fit and function interchangeable with Amphenol, TE Deutsch and Souriau equivalents at the same shell size and insert arrangement.
