YEONHAB Precision — YH-38999 Series III Style
YH-38999 is kept as a commercial Series III-style engineering alternative. It is not presented as a QPL replacement.
Published style coverage
The reviewed catalog covers MIL-DTL-38999 I / III / IV style families, MIL-STD-1560 insert arrangements, /20 wall mount, /24 jam nut and /26 straight plug styles, plus normal/A/B/C/D/E polarization.
Qualification status
The source explicitly identifies the YH-38999 commercial family as Non-QPL. ConnectorAtlas therefore keeps it in an engineering-alternative lane rather than a qualified-source lane.
Boundary: technical similarity is not an interchangeability approval. Verify drawing, program requirements, qualification and sourcing before substitution.
