The height above board is 0.248\" (6.30mm), so the 7mm stack leaves about 0.7mm clearance between the header body and the opposing board — enough for component keep-outs on the underside. The 8mm stack gives a bit more room for taller passives on the bottom board. Both heights use the same footprint, so you can swap between them without a board respin. The board guide aligns the header during placement so it doesn't skew on the paste; the solder retention pads anchor it to the board during reflow and add mechanical strength against shear forces from the mating cable or vibration. For a 40-position SMT part at 0.50mm pitch, those retention features are what keep the joints from cracking under thermal cycling. It's a current-production part with no announced end-of-life. No direct manufacturer cross-reference exists; the part is specific to the Hirose DF17 series.","metaTitle":"Hirose DF17(4.0)-40DP-0.5V(57) 40 Pos 0.50mm SMT Header","metaDescription":"Hirose DF17 series 40-position SMT header, 0.50mm pitch, 7mm/8mm stacking height.
