32-Position Mezzanine Receptacle at 0.50mm Pitch
The Hirose DF12-32DS-0.5V(86) is a 32-position receptacle with center strip contacts, part of the DF12 series of board-to-board mezzanine connectors. The 0.020" (0.50mm) pitch packs 32 contacts into a compact footprint — tight enough that the board layout needs 0.3mm trace-and-space rules to route the inner rows. The 2.70mm height above board works with the three listed mated stacking heights of 3.5mm, 4mm, and 5mm, so one connector on the BOM can serve different board-spacing requirements in the same assembly.
Obsolete — Sourced Through Surplus Channel
The DF12-32DS-0.5V(86) is listed as Obsolete. No factory orders are accepted; the only supply is through independent distributor surplus and broker inventory. The DF12 series continues in production with other position counts and plating options, so a pin-compatible replacement within the same family may exist — confirm the position count, pitch, and stacking height against the current DF12 catalog before requalifying.
What Mates and Stacks
The three mated stacking heights — 3.5mm, 4mm, and 5mm — are set by the header's own height above board; pick the header part number that gives the board spacing your design needs.
