The SMT termination suits automated pick-and-place assembly. ## 4mm Stack Height — Board Spacing Constraint This is a fixed value for this variant — the DF40 series offers other heights (3mm, 4.5mm) through different suffix codes. If your enclosure or module height budget is tighter than 4mm, check the DF40 family for a lower-profile option. ## Position Count vs. Siblings At 90 positions, this is a high-density member of the DF40 series. If your BOM calls for 80 signals, that part saves 10 positions of board area; if you need 90, this is the one.","metaTitle":"Hirose DF40HC(4.0)-90DS-0.4V(51), 90-pos, 0.40mm pitch","metaDescription":"Hirose DF40 receptacle, 90 positions, 0.40mm pitch, 4mm stacking height.
