The Hirose DF12B-32DS-0.5V(86) is officially listed as Obsolete. That means Hirose has stopped production — no more factory orders, no last-time-buy window. If this part is on your BOM, you are looking at the surplus and broker channel to fill it.
The DF12B-32DS-0.5V(86) is a 32-position, 0.50mm pitch, dual-row board-to-board receptacle from Hirose's DF12 series. Mated stacking heights are 3.5mm, 4mm, or 5mm, depending on the matching DF12 header height you pair it with. This kind of connector is used in compact portable electronics, camera modules, and any assembly where two parallel PCBs need a low-profile, high-density signal interconnect.
Mated Stacking Heights and Board Layout
The 0.50mm pitch packs 32 signal lines into a narrow footprint — the board layout needs tight routing discipline, but the dual-row arrangement keeps the connector width manageable. The three available mated stacking heights (3.5mm, 4mm, 5mm) give you some z-height flexibility without changing the receptacle. Pick the matching DF12 header with the corresponding height to set the gap between boards.
Contact Plating and Signal Duty
Gold contacts at 8.00µin thickness are a solid choice for signal-level interconnects that mate and unmate over the life of the product — think battery swaps, module replacements, or test headers. For a single permanent install, tin plating would work, but the gold here gives you margin on contact reliability if the connector sees field service.
