Product details

32-Position Dubox™ Receptacle — Board-to-Board Fit

Mated stack height is 11.04 mm, a common mezzanine spacing that fits many board-to-board applications without requiring custom standoffs.

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.

Frequently asked questions

What is the closest alternative to 71991-316LF?

The 71991-315LF is the same series with 30 positions instead of 32. All other specs — pitch, row spacing, gold plating, stack height, housing — are identical.
