0.100" Pitch Breakaway Header — 3 Circuits, Right-Angle
Molex 0022288031 is a 3-position, single-row breakaway header from the KK254 series (42377 family). Unshrouded means no keying rib; orientation is set by the PCB layout and the mating housing's polarization. That saves vertical clearance in tight enclosures but demands board-edge clearance for the mating connector. Breakaway construction means the header ships as a longer strip; you snap off the exact number of positions needed. For a 3-position order, you get a pre-snapped 3-circuit piece — no waste, no extra inventory.
Tin Plating and Mating Life
That's a thick tin layer — it handles moderate mating cycles without galling, typical for a connector that gets mated once or twice in the field and then stays connected. The housing is glass-filled nylon (PA) rated UL94 V-0.
