It uses a 0.50mm pitch dual-row layout with gold-plated center strip contacts, surface-mounted to the PCB. The mated stacking heights span 3.5mm, 4mm, and 5mm, giving the board layout engineer flexibility in z-height budget for parallel PCB assemblies. A built-in board guide aids alignment during mating, protecting the fine-pitch contacts from shear damage. The 0.50mm pitch is fine enough to route signals between the pads on a standard PCB without resorting to micro-vias, but it does demand careful trace-width planning — a 0.50mm pitch leaves about 0.25mm between pad edges for a single trace between rows. The listed mated stacking heights of 3.5mm, 4mm, and 5mm correspond to specific header variants in the DF12 series, so the header selection locks the final board spacing.","metaTitle":"Hirose DF12A-20DS-0.5V(80)","metaDescription":"Hirose DF12A-20DS-0.5V(80) 20-position receptacle, 0.50mm pitch, gold contacts, SMT.
