15-Position 3-Row Plug Housing for Universal MATE-N-LOK II
Row Spacing 0.250" — 3-Row Footprint
The 0.250" (6.35 mm) row spacing is the defining board-side dimension for this housing. A 3-row, 15-position layout means the mating header's pin field is a 5x3 grid at that pitch.
The crimp contacts — male pin or female socket, depending on the application — are ordered by a separate part number (TE Connectivity's Universal MATE-N-LOK II contact family). The housing accepts both genders, so the same 15-position plug can serve as the male or female half of the wire-to-wire or wire-to-board pair, depending on which contact you load. Confirm the contact wire range matches your harness AWG before committing the BOM line.
Latch Lock — Vibration-Resistant Mate
The latch lock on this rear-section plug provides positive retention against the mating header's locking ramp. No secondary locking device is required for most duty cycles, though the series offers a TPA (terminal position assurance) insert for high-reliability builds.
