The 0.016\" (0.40mm) pitch on two rows packs 100 circuits into a compact footprint — the tight pitch demands careful trace escape routing and via fanout on the PCB, especially for dense signal layers. ## Stack Height Options and Mating Flexibility This plug supports six mated stacking heights: 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, and 4mm. The height is set by pairing the plug with the matching receptacle (DF40C-100DS-0.4V(51) or equivalent) — the same PCB footprint works across all heights, so you can change board spacing without a layout revision. For applications requiring frequent field reconnection, a thicker gold layer would be preferable; here the thin flash keeps cost down while maintaining corrosion resistance in the mated state. ## Position Count Comparison Across the DF40C Subfamily Within the DF40C subfamily, the 100-position DF40C-100DP-0.4V(51) sits at the top of the position range.","metaTitle":"Hirose DF40C-100DP-0.4V(51) Plug, 100 Pos, 0.40mm Pitch","metaDescription":"Hirose DF40C-100DP-0.4V(51) 100-position plug, 0.40mm pitch, gold contacts, SMT.
