The Hirose BM28B0.6-10DS/2-0.35V(53) is a 10-position receptacle with center strip contacts from the BM28 series, designed for board-to-board stacking at a mated height of 0.6mm.
The 0.35mm pitch is the tightest selection parameter here — it dictates the PCB footprint's trace-and-space capability and the mating half's contact layout. At this density, a standard FR-4 board with 1oz copper may need controlled impedance routing for signal integrity above a few hundred MHz.
The BM28B0.6-10DS/2-0.35V(53) shares the same 0.35mm pitch, 0.6mm mated height, and gold plating with the 16-position BM28B0.6-16DS/2-0.35V(53) and the 20-position BM28B0.6-20DS/2-0.35V(51). All three use the same footprint pitch and stack height, so a board laid out for one can accept the others if the position count matches.
