The 2-647127-4: This is a 4-position, single-row header from the MTA-156 series, pitched at 0.156" (3.96mm) for wire-to-board applications. The shrouded 4-wall design and friction lock keep the mating housing seated against vibration—handy in industrial enclosures where a half-turn loose is a dropout.
Within the MTA-156 series, the 4-position shrouded header with friction lock is the direct fit. No pin-compatible alternative from another series is documented.
