20-Position SliderZ Header at 0.050" Pitch
The Molex 442450020 is a 20-position header from the SliderZ 44245 series, using hermaphroditic contacts so the same part serves both mating halves. The 0.050" (1.27 mm) pitch packs 20 circuits into a dual-row footprint that saves board space but demands precise alignment during assembly — the tight pitch leaves little room for registration error.
At 0.050" (1.27 mm) pitch, the 442450020 uses a denser grid than the 0.100" pitch common in wire-to-board headers. The dual-row 20-position layout requires a PCB footprint with 1.27 mm row-to-row spacing — confirm the board layout matches before committing the BOM line. The hermaphroditic contact design means the same footprint works for both header and receptacle halves, simplifying the PCB layout for board-to-board or cable-to-board applications where both sides are on the same board.
