Compared to the 32-position sibling 71991-316LF, this 48-position version adds 16 circuits in the same dual-row footprint — the extra positions extend the board edge length by about 1.6\" (40.6mm) at 0.100\" pitch. All positions are loaded, so no blank cavities to work around.","metaTitle":"71991-324LF Amphenol ICC (FCI) Dubox™ 48-Position Female","metaDescription":"71991-324LF: Amphenol ICC Dubox™ 48-position, 0.100\" pitch, through-hole female socket receptacle. 30µin gold mating finish, 11.04mm stack height.
