Product details

Mezzanine Board-to-Board Receptacle for 0.50mm Pitch Stacks

The Hirose DF17(3.0)-20DS-0.5V(57) is a 20-position receptacle with center strip contacts from the DF17 series, designed for board-to-board mezzanine stacking. The surface-mount termination suits automated reflow assembly, and the 0.138" (3.50mm) height above board works with three mated stacking heights — 5mm, 5.5mm, and 7mm — giving board layout engineers flexibility in z-axis spacing between parallel PCBs.

Solder retention features anchor the part during reflow and improve shear strength from cable or board handling after assembly.

Mating Compatibility and Stacking Heights

The three supported mated stacking heights — 5mm, 5.5mm, and 7mm — are set by the header height variant chosen.

Frequently asked questions
