1.25 mm pitch, 7 positions, right-angle SMT
Molex Micro-Lock PLUS 5055670781 is a 7-position single-row header on 1.25 mm pitch, terminated by surface-mount solder in a right-angle orientation. The shrouded-4-wall housing protects the male square pins, and the locking ramp secures the mating receptacle against vibration — no separate latch hardware needed.
Footprint and board-fit decisions
The 1.25 mm pitch and single-row layout keep the PCB footprint narrow — the insulation height is 0.154" (3.90 mm) above the board surface, which sets the mated stack height with the matching receptacle. The glass-filled nylon housing (UL94 V-0) withstands reflow temperatures and provides flame retardancy.
ROHS3 compliant per Molex. No direct pin-compatible replacement listed within the Micro-Lock PLUS 505567 series; the 7-position count is specific to this order code.
