The 0.016\" (0.40mm) pitch and 2-row layout pack 40 I/O into a narrow footprint, suited for compact portable electronics, handheld devices, and camera modules where board real estate is tight. Gold contact finish at 1.97µin covers the mating surface for reliable low-current signal connections. The housing includes pick-and-place features and solder retention pads for automated SMT assembly. ## 40 Positions at 0.40mm Pitch — What the Density Means At 0.016\" (0.40mm) pitch, the DF40TC(3.0)-40DS-0.4V(58) demands fine-line PCB routing — trace widths and spaces below 0.20mm are typical to escape the connector footprint. The 40 positions in two rows keep the body width narrow, but the tight pitch limits per-contact current to signal-level duty; this is not a power interconnect. ## Comparing Position Counts and Stack Heights The DF40TC(3.0)-30DS-0.4V(58) shares the same 0.016\" (0.40mm) pitch, 2-row layout, 3mm stack height, and gold flash plating — only the position count drops to 30, making it the choice when the I/O requirement is lower. For the same 40 positions but a taller board gap, the DF40TC(3.5)-40DS-0.4V(58) offers a 0.134\" (3.40mm) mated height, which adds clearance for thicker components on the underside of the top PCB. All three are active and RoHS compliant.","metaTitle":"Hirose DF40TC(3.0)-40DS-0.4V(58)","metaDescription":"Hirose DF40T series receptacle, 40 positions, 0.016\" (0.40mm) pitch, 2 rows, gold contacts, 3mm mated stack height.
