The Hirose DF12NC(3.0)-10DP-0.5V(51) is a 10-position, dual-row header from the DF12 series, using outer shroud contacts in a surface-mount package. It's designed for parallel board stacking at a fixed 3 mm mated height, with the 0.50 mm pitch keeping the footprint compact for dense PCB layouts.
Position Count and Stack Height Drive the Fit
The 10 positions match a 10-circuit BOM line exactly — no spare or missing contacts. The 0.50 mm pitch also dictates trace routing width between pads — standard 0.25 mm traces with 0.25 mm clearance fit, but anything wider needs a pitch bump to a 0.80 mm or 1.00 mm series.
The DF12NC(3.0)-10DP-0.5V(51) shares the same 0.50 mm pitch, 3 mm stack height, and gold plating with the 30-position DF12NC(3.0)-30DP-0.5V(51) and 50-position DF12NC(3.0)-50DP-0.5V(51). No other spec changes across the range, so the footprint scales linearly with position count.
