The 0.016\" (0.40mm) pitch packs 50 circuits into a dual-row footprint that keeps PCB real estate under control. Gold-plated contacts with 2.00µin (0.051µm) thickness handle the mating cycles typical of internal device interconnects — think camera modules, display panels, or battery management boards inside portable electronics. The plug mates with the matching DF40 receptacle to achieve stacking heights from 1.5mm up to 4mm, selectable by choosing the appropriate receptacle variant. That range covers everything from ultra-slim phone builds to slightly taller industrial sensor boards, all from the same plug footprint. ## Stack Height Selection and Board Layout Fit The mated stacking heights — 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, and 4mm — are set by the receptacle height, not the plug. The DF40C-50DP-0.4V(51) plug itself has a fixed 0.045\" (1.14mm) height above the board. When laying out the PCB, the 0.40mm pitch demands careful trace routing between pads; a 0.20mm trace with 0.20mm spacing is feasible on standard FR-4 with a fine-line etch. The dual-row arrangement keeps the connector width manageable at roughly 5.6mm across the outer contacts. The 50-position count is a common density for parallel data buses or LVDS links in compact camera modules and display interfaces. The DF40C-50DP-0.4V(51) sits between the 44-position DF40C-44DP-0.4V(51) and the 60-position DF40C-60DP-0.4V(51) in the same series. All three share the identical 0.016\" (0.40mm) pitch, 0.045\" (1.14mm) plug height, gold contact finish at 2.00µin, and the same stacking height range. The choice comes down to the number of signals your BOM requires — 44 circuits for a narrower bus, 50 for a standard-width interface, or 60 for the densest routing. The footprint grows in length by 0.40mm per additional position pair, so the board layout scales predictably.","metaTitle":"Hirose DF40C-50DP-0.4V(51) Plug, 50 Pos, 0.40mm Pitch","metaDescription":"Hirose DF40C-50DP-0.4V(51) 50-position plug, 0.40mm pitch, gold contacts, SMT, 1.14mm height.
