Surface-mount termination with gold-plated contacts (2.00µin / 0.051µm thickness) on the mating interface. The 0.40mm pitch means the board layout needs fine-line routing and micro-vias to escape the inner rows; this is not a connector for coarse 2-layer boards. The 70-position count is the middle option in the DF40C(2.0) family. The 60-position and 50-position versions (DF40C(2.0)-60DS-0.4V(51) and DF40C(2.0)-50DS-0.4V(51)) are also direct drop-in alternatives for lower-density designs, all sharing the same 0.077\" (1.95mm) height above board.","metaTitle":"Hirose DF40C(2.0)-70DS-0.4V(51) 70 Pos 0.40mm Receptacle","metaDescription":"Hirose DF40C(2.0)-70DS-0.4V(51) receptacle, 70 positions, 0.40mm pitch, 2mm stacking height, gold contacts, SMT.
