The DF12(5.0)-60DP-0.5V(81): This is a 60-position header from the Hirose DF12 series, a board-to-board mezzanine connector with a 0.50mm pitch and a 5mm mated stacking height. The dual-row layout and outer shroud contacts are designed for parallel PCB stacking in compact electronics.
The DF12(5.0)-60DP-0.5V(81) is marked obsolete by Hirose. That means no further production runs from the manufacturer, and stock is limited to whatever remains in distribution channels.
Finding a replacement or alternative
Because this part is obsolete, the first step is identifying a pin-compatible alternative within the DF12 series. The 60-position, 0.50mm pitch, 5mm stacking height footprint narrows the search to other DF12 headers with the same (5.0) stack height code and 60 circuits. No direct successor is listed. A cross-reference against the full DF12 series catalog is needed to find a current-production part that matches the board layout and mating receptacle.
