A board-layout engineer evaluating this footprint should confirm the 0.50mm pitch and 3mm stacking height match the application before committing to a last-time buy quantity. ## What the 3mm Stacking Height and 0.50mm Pitch Mean for the Fit The 3mm mated stacking height sets the z-axis gap between parallel PCBs — tight enough for slim handheld devices but requiring the mating board to clear any tall components on the underside. The 0.50mm pitch drives the PCB footprint: each row of ten contacts occupies about 4.5mm of board edge, and the fine pitch demands careful routing clearance between pads. The outer shroud contacts provide mechanical alignment during mating and protect the signal pins from side-load damage during board assembly.","metaTitle":"Hirose DF12B(3.0)-20DP-0.5V(86) Header, 20 Pos, 0.50mm Pitch","metaDescription":"Hirose DF12B(3.0)-20DP-0.5V(86) 20-position 0.50mm pitch board-to-board header. 3mm stacking height, gold contacts.
