Possible NASM form, to verify: MS200051 / NASM200051. If a conversion exists, NASM is the converted form of the MS standard with an identical part number (e.g. MS90353U Notice 1). Not every MS has a NASM successor: verify the NASM document exists; the part may still be stocked as MS. MS90353U Notice 1: canceled and superseded by NASM90353, part numbers identical (everyspec) ↗
