1.25mm pitch, 20-position SMT header for wire-to-board
The 5054332081 is a 20-position, dual-row header from the Molex Micro-Lock PLUS 505433 series, designed for board-to-cable/wire applications at a 1.25mm pitch. It is a surface-mount, shrouded-4-wall header with a latch holder fastening system, intended for environments where vibration resistance is needed — the latch prevents accidental unmating.
Contact plating and sourcing posture
The insulation height is 0.285" (7.25mm) — account for this above the PCB when planning component keep-out zones. For a given wire size, consult the Micro-Lock PLUS crimp terminal datasheet for the derated current.
