Board-Stacking Selection: 1.5mm Mated Height, 0.40mm Pitch
The Hirose DF37NC(1.5)-30DS-0.4V(53) is a 30-position receptacle from the DF37 series, designed for parallel board-to-board stacking at a fixed 1.5mm mated height. The 0.016" (0.40mm) pitch and dual-row layout pack 30 circuits into a compact footprint — typical for smartphone, tablet, and wearable PCBA stacking where z-height is tight.
What the 1.5mm Stack Height Means for Your Board Stack-Up
The 1.5mm mated stacking height is the dimension between the top of the bottom board and the bottom of the top board when mated. That 1.5mm envelope includes the connector body height plus the clearance for the mating header — no additional standoffs needed. If your design has a tighter or looser z-budget, the DF37 series offers other stack height variants; this specific suffix (1.5) locks the height at 1.5mm.
This receptacle mates with the corresponding DF37 series header (the plug side) at the same 0.40mm pitch and 1.5mm stack height. Both halves use surface-mount termination — no through-hole soldering.
