The mated stack height is 11.3mm, meaning the mated pair occupies that vertical space above the board. The insulation height of 0.346\" (8.80mm) is the header body height alone; plan your enclosure clearance accordingly. A board guide feature assists alignment during assembly, useful for automated pick-and-place or manual insertion into tight enclosures.","metaTitle":"JST B14B-XASK-1-A(LF)(SN) Header – 14 Position 2.5mm Pitch","metaDescription":"JST XA series 14-position header, 2.50mm pitch, 3A/250V, tin-plated contacts, locking ramp.
