It uses a 0.40mm pitch and a dual-row layout with center strip contacts, designed for parallel PCB stacking at a fixed mated height of 3.5mm. The 0.40mm pitch packs 80 circuits into a narrow footprint, which means the board layout needs fine trace routing and via clearance. The receptacle is surface-mount only, so the solder paste stencil and reflow profile must be matched to the 0.40mm pitch to avoid bridging between adjacent contacts. ## Position Count vs the 60-Position Sibling The DF40HC(3.5)-80DS-0.4V(51) shares the same 0.40mm pitch, 3.5mm stack height, gold plating, and SMT termination as the 60-position DF40HC(3.5)-60DS-0.4V(51). If your BOM calls for 60 I/O lines, the 60-position variant saves board space and cost; if you need the full 80, this is the part. No other spec changes between the two. ## Mating Half and Assembly This receptacle mates with the corresponding DF40 series header that has the same 0.40mm pitch and 3.5mm stacking height specification. The header is also a surface-mount, center-strip-contact design. When ordering, match the header's position count to this receptacle's 80 positions. The gold flash on both halves is adequate for the few mating cycles a mezzanine connector sees in production — the contacts are not designed for repeated field disconnect.","metaTitle":"Hirose DF40HC(3.5)-80DS-0.4V(51) Receptacle, 80 Pos","metaDescription":"Hirose DF40 series receptacle, 80 positions, 0.40mm pitch, 3.5mm stacking height.
