The Molex 504622-2410 is a 24-circuit board-to-board plug assembly on a 0.35 mm pitch. That pitch is the tightest selection parameter here — it sets the PCB pad layout and rules out any standard-pitch mezzanine socket. The 24 circuits match the BOM position count directly. This is an Embossed Tape packaged part, intended for automated pick-and-place assembly.
It is ROHS3 compliant, clearing the regulatory gate for EU and similar markets.
