80-Position, 0.40mm Pitch — Tight-Density Board-to-Board Receptacle
The Hirose DF30FC-80DS-0.4V(82) is an 80-position receptacle from the DF30 series, designed for high-density board-to-board stacking.
Stack Height and Z-Height Budget
The 0.02mm difference between the component height and the mated stack means the plug side sits nearly flush against the board surface — a critical dimension when the enclosure gap is under 1.0mm. The 0.9mm mated stack height is the final z-height after full engagement, so the board-to-board spacing is fixed once the pair is mated.
Gold Plating — Signal Duty, Not Repeated Mating
The contacts carry 2.00µin of gold plating.
The (82) suffix in the order code indicates a specific packaging or revision variant; the base product number DF30F covers the series platform.
