The Amphenol FCI 68695-148HLF is a 48-position, dual-row unshrouded header from the BERGSTIK® II series, designed for board-to-board interconnect on a standard 0.100" (2.54mm) pitch grid.
The 0.100" (2.54mm) pitch is the industry-standard grid — the footprint matches any 0.100" dual-row through-hole pattern, so board layout is straightforward with no special keep-out zones. The 48 positions loaded all give you the full circuit count, which is the primary BOM match criterion; if your design calls for fewer circuits, the unshrouded design lets you depopulate pins on the mating receptacle side, but the header itself is fully populated. For a board-to-board interconnect that may see field service or multiple reconnections, that gold thickness buys you reliable contact resistance over the life of the assembly. The 0.090" (2.29mm) post length is short, designed for standard PCB thickness; check your board stack-up if you're routing through a thick backplane.
