For a taller stack, the DF40C(2.0)-20DS-0.4V(51) lifts the mated height to 1.95mm while keeping the same 0.40mm pitch and 20 positions; that variant trades a lower profile for a slightly taller envelope if your board spacing allows. The thin gold layer provides corrosion resistance on the mating surface without the cost of a heavy-gold deposit; it handles the few dozen cycles typical of a board-to-board mezzanine connection during assembly and rework. This is not a connector rated for repeated field disconnect or high-current power delivery — the 0.40mm pitch physically limits per-contact ampacity well below what the plating could sustain.","metaTitle":"Hirose DF40C-24DS-0.4V(51) Receptacle, 24 Pos, 0.40mm Pitch","metaDescription":"Hirose DF40C-24DS-0.4V(51) receptacle, 24 positions, 0.40mm pitch, 1.5mm stacking height.
