The closest functional alternative is the 71991-315LF, which shares the same pitch, row spacing, gold plating thickness, stack height, and housing color — the only difference is 30 positions vs 32 positions. If the BOM calls for 32 positions, this is the exact match; the 30-position sibling leaves two positions unpopulated on a 32-pin header footprint. Through-hole solder termination with 0.118\" (3.00 mm) post length — fits standard 0.062\" PCBs with enough tail for a reliable solder fillet.","metaTitle":"71991-316LF Amphenol ICC Dubox™ 32-Position Female Socket","metaDescription":"Active 32-position dual-row receptacle, 0.100\" pitch, 30 µinch gold mating finish, 11.04 mm stack height.
