0.50mm Pitch Board-to-Board Header — SMT, 30 Positions, 3.5mm Stack
The Hirose DF12B(3.5)-30DP-0.5V(86) is a 30-position, 2-row header with outer shroud contacts from the DF12 series. It mates to a matching DF12 receptacle to form a board-to-board mezzanine connection with a fixed 3.5mm mated stacking height.
At 0.50mm pitch, the trace escape from the inner rows requires a via-in-pad or fine-line PCB process.
Obsolete — Sourcing and Replacement Planning
The DF12B(3.5)-30DP-0.5V(86) is marked obsolete by Hirose. An engineer or sourcing agent evaluating a replacement should look for a pin-compatible Hirose DF12 series header with the same 0.50mm pitch, 30 positions, 2 rows, and 3.5mm stacking height — the DF12 family includes multiple stack-height variants, so the (3.5) suffix in the order code is the dimension that locks the mezzanine gap.
