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.","metaTitle":"Hirose DF17(2.5)-26DP-0.5V(57) Header, 26 Pos, 0.50mm Pitch","metaDescription":"Hirose DF17 series header, 26 positions, 0.020\" (0.50mm) pitch, gold-plated contacts, SMT.
