SMT termination with integrated pick-and-place and solder retention features means this part is set up for automated assembly — no secondary hold-down hardware needed. ## Position Count Variant — 40 vs 30 Positions For a lower circuit count at the same 3.5mm stack height, the DF40TC(3.5)-30DS-0.4V(58) drops to 30 positions while keeping the same 0.016\" (0.40mm) pitch and 0.134\" (3.40mm) height above board. The footprint length scales with position count, so the board layout must match the BOM line count exactly — no depopulating unused positions on a 40-position part to get 30 circuits. No official second-source cross-reference exists; the DF40T series is Hirose proprietary, so the mating half must also be a DF40T header.","metaTitle":"Hirose DF40TC(3.5)-40DS-0.4V(58) Receptacle, 0.40mm Pitch","metaDescription":"Hirose DF40TC(3.5)-40DS-0.4V(58) receptacle, 0.40mm pitch, 40 positions, 3.5mm mated stack height.
