The 0.016\" (0.40mm) pitch and dual-row layout pack 40 signals into a compact footprint, making this part a fit for dense handheld or portable device PCBs where z-height and board area are both constrained. ## 0.40mm Pitch and 1.5mm Stack Height The 0.40mm pitch drives the PCB routing — traces between pads need controlled impedance design rules and a fab capable of fine-line etching. The mated stacking height of 1.5mm (0.057\" above board on the receptacle side) sets the z-budget between parallel boards; confirm the mating header's height sums to this total.","metaTitle":"Hirose DF40TC-40DS-0.4V(58) 40-Pos 0.4mm Receptacle","metaDescription":"Hirose DF40TC-40DS-0.4V(58) 0.4mm pitch receptacle, 40 positions, 1.5mm stack height, gold contacts, SMT with pick-and-place.
