The Hirose DF12A-32DS-0.5V(81) is a 32-position, dual-row receptacle with center strip contacts from the DF12 series, designed for board-to-board mezzanine stacking at a 0.50 mm pitch. The 32 positions match a 32-circuit BOM line for parallel data buses or dense I/O arrays. Gold plating at 8.00µin on the contacts is adequate for signal-level duty in controlled environments, but not rated for the high mating-cycle counts of a field-service connector.
Mated stacking heights: 3.5mm, 4mm, 5mm
This receptacle supports mated stacking heights of 3.5mm, 4mm, and 5mm when paired with the matching DF12 header. The 3.5mm option is the lowest profile in the DF12 series, suited for tight z-height budgets in portable or embedded designs.
Obsolete — plan for a replacement or surplus sourcing
No official successor from Hirose is listed. For a new design, consider current-production DF12 series variants at the same 0.50 mm pitch and 32 positions, but verify stack height and footprint compatibility.
Mates with DF12A-32DP-0.5V(81) header
This receptacle mates with the Hirose DF12A-32DP-0.5V(81) header, which is the 32-position, 0.50 mm pitch, dual-row, surface-mount plug with center strip contacts. The mated pair achieves the stacking heights listed above. Confirm the header's plating and stack height variant match your assembly height requirement before committing the BOM line.
