24-Pin 2.00mm Pitch Unshrouded Header — Board Fit and Routing
The 57102-F08-12LF: The 0.157" (4.00mm) mating pin length and 0.118" (3.00mm) solder post length set the board-to-board stack height and the through-hole depth — a standard footprint for 2.00mm pitch dual-row receptacles. Rated 2A per circuit at 200V AC/DC, with gold flash on the mating interface and tin-plated solder posts at 2.00µm thickness. The tin posts solder reliably into standard plated through-holes.
