MIL-DTL-38999 Series IV uses a breech (Breech-Lok) quarter-turn coupling instead of the threaded Series III coupling. It is scoop-proof, tolerant of blind mating, and qualified for high-vibration environments — which is why Series IV is specified where a threaded connector would back off or where the mating interface cannot be seen. The D38999/47 slash sheet is the straight plug in the Series IV family and mates with the Series IV plug styles D38999/46 and D38999/47. Cross-reference values above are form, fit and function equivalents, not price comparisons.
