The real selection variable here is the mated stack height: this plug supports six different heights (1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, and 4mm) depending on which receptacle height variant you pair it with. That range covers everything from ultra-thin phone-style stacking to slightly taller mezzanine gaps where components sit under the board pair. The plug itself sits 1.14mm above the board — that's the z-height of the component on the top side, before the receptacle adds its own height.","metaTitle":"Hirose DF40C-44DP-0.4V(51) Plug, 44 Pos, 0.40mm Pitch","metaDescription":"Hirose DF40C-44DP-0.4V(51) plug, 44 positions, 0.40mm pitch, 1.14mm height, gold contacts.
