Product details

0.50mm Pitch Board-to-Board Header for Tight Stack Heights

The Hirose DF17(2.5)-26DP-0.5V(57) is a 26-position header from the DF17 series, designed for parallel board-to-board stacking. The connector supports mated stack heights of 5.5mm or 6.5mm, which sets the board spacing for the assembly — pick the height that matches your mezzanine gap.

26 Circuits at 0.50mm Pitch vs 30-Circuit Sibling

At the same 0.020" (0.50mm) pitch and gold-plated contacts, the 26-position DF17(2.5)-26DP-0.5V(57) shares its footprint class with the 30-position DF17(2.0)-30DP-0.5V(57) — the difference is circuit count, not board real estate. The 26-position member uses a shorter body length, so the decision is purely about matching the BOM position count. Both are active and RoHS compliant.

Frequently asked questions

What is the stacking height for DF17(2.5)-26DP-0.5V(57)?
