The decision is strictly a BOM circuit-count match — the footprint, board keep-out zone, and mating half are identical. If the design calls for 90 I/O, the 100-position part still fits physically but leaves ten contacts unterminated; the 90-position version saves a few cents on the BOM line.","metaTitle":"Hirose DF40C-100DS-0.4V(51) Receptacle, 100 Pos, 0.4mm Pitch","metaDescription":"Hirose DF40C-100DS-0.4V(51) receptacle, 100 positions, 0.4mm pitch, 1.5mm stacking height.
