The sibling DF40TC(3.5)-20DS-0.4V(58) shares the same 20 positions, 0.40mm pitch, gold flash, and dual-row layout, but its mated stacking height is 0.134\" (3.40mm). That 0.40mm difference is the only meaningful delta — the board-to-board z-budget decides which one lands on the BOM. Everything else (footprint, terminal, plating) is identical, so swapping between them is a board stack-up call, not a re-layout. ## Sourced to order — active, no LTB pressure The lifecycle status is Active.","metaTitle":"Hirose DF40TC(3.0)-20DS-0.4V(58) 20-Pin 0.4mm Receptacle","metaDescription":"Hirose DF40TC(3.0)-20DS-0.4V(58) 20-position 0.40mm pitch receptacle, 3mm mated stacking height, gold contacts.
