It mates with the corresponding Micro-Lock PLUS receptacle (crimp or IDC) to form a board-to-wire connection. The 1.25mm pitch keeps the PCB footprint compact while still allowing manual routing on two-layer boards. ## Board mounting and footprint details Pick-and-place compatible packaging (Tape & Reel) means the header can be loaded directly into a placement machine for high-volume assembly. No official second-source or cross-reference is listed, so stick with the Molex part number for BOM consistency.","metaTitle":"Molex 5054332091 Micro-Lock PLUS Header, 20 Pos, 1.25mm, SMT","metaDescription":"Molex 5054332091 Micro-Lock PLUS 505433 header, 20 circuits, 1.25mm pitch, shrouded, gold plating, SMT, active production.
