The Hirose DF12NB(3.0)-36DS-0.5V(51) is a 36-position receptacle with center strip contacts from the DF12 series, designed for parallel board stacking at a mated height of 3mm. The 0.020" (0.50mm) pitch packs 36 circuits into a dual-row footprint that fits tight board layouts where routing density matters more than per-contact current — the narrow pitch limits current per circuit, so this is a signal interconnect, not a power rail.
Stacking Height and Board Clearance
The mated stacking height is 3mm, and the receptacle itself sits 0.087" (2.20mm) above the board surface. That 2.20mm height sets the keep-out zone for components on the underside of the mating board — anything taller than about 0.8mm clearance between the bottom of the header and the receptacle body risks interference. The 3mm stack is the standard DF12NB(3.0) height variant; the "(3.0)" in the order code directly encodes that dimension, so swapping to a different DF12NB height variant changes the board gap.
Position Count Comparison Across the DF12NB(3.0) Sub-Series
The 36-position DF12NB(3.0)-36DS-0.5V(51) sits between the 32-position DF12NB(3.0)-32DS-0.5V(51) and the 40-position DF12NB(3.0)-40DS-0.5V(51) in the same sub-series. All three share the identical 0.50mm pitch, 3mm stacking height, 2.20mm above-board height, and gold-plated contacts at 8.00µin. A 30-position DF12NB(3.0)-30DS-0.5V(51) is also available for lower-density boards.
