The 0.50mm pitch sets the pad layout on both boards — the footprint is non-negotiable; any replacement must match that centreline spacing exactly. If your enclosure or mezzanine card cage was designed for that gap, a taller or shorter header won't fit without reworking the standoffs or card guides. ## Mounting and board retention The board guide aligns the header during reflow and takes the shear load when the mating half is inserted — keeps the solder joints from taking the full insertion force.","metaTitle":"Hirose DF12(3.0)-20DP-0.5V(80) Header, 0.50mm Pitch, 20 Pos","metaDescription":"Hirose DF12 series 20-position header, 0.50mm pitch, 3mm stacking height.
