16 positions at 0.100" pitch — single-row board-to-board receptacle
The 71920-316LF: It accepts a mating pin header from either the bottom or top entry, giving flexibility in mezzanine or coplanar board layouts.
The square contact shape mates with standard 0.025" square pin headers, common across the Dubox™ and many other 0.100" pitch header families.
Single-row vs dual-row — the 71991 series comparison
If your board has the space for two rows, the 71991-308LF gives the same circuit count in a wider, taller package; if you're tight on width, the single-row 71920-316LF saves board area.
