Against the 20-position sibling BM20B(0.8)-20DS-0.4V(53), the difference is purely positional — the footprint pad layout changes, but the pitch and stack height are identical, so the board routing density stays the same.","metaTitle":"Hirose BM20B(0.8)-24DS-0.4V(53) Receptacle, 0.40mm Pitch","metaDescription":"Hirose BM20B series receptacle, 24 positions, 0.016\" (0.40mm) pitch, gold contacts, 0.80mm stack height.
