Mezzanine Board-Stacking Receptacle at 0.50mm Pitch
The Hirose DF17(4.0)-80DS-0.5V(57) is an 80-position receptacle from the DF17 series, designed for parallel board-to-board stacking. It uses a 0.020" (0.50mm) pitch across two rows of center strip contacts, packing 80 circuits into a compact SMT footprint. The gold contact finish suits repeated mating cycles typical in production and field-service environments.
Stacking Heights and Z-Height Budget
This receptacle supports three mated stacking heights: 6mm, 6.5mm, and 8mm. That range gives the board designer flexibility to fit the interconnect into different z-height envelopes between stacked PCBs.
SMT Assembly and Board Retention
The board guide aligns the receptacle during placement, and the solder retention pads hold it steady through reflow, reducing tombstoning and misalignment risk. Tape & Reel packaging (Cut Tape option available) feeds directly into standard pick-and-place machines.
Active lifecycle status — no end-of-life or last-time-buy concerns on this part. No official cross-reference or second-source is recorded; the DF17 series is a Hirose proprietary design.
