The 2080353031: This is a Molex CONNTAK50 208035 series header, 3 positions in a single row, with a 1.80mm pitch that sets the board footprint and the per-contact current ceiling. Termination is surface mount, so the part is placed on the PCB and reflow-soldered. The pick-and-place feature means the top of the housing is flat and vacuum-compatible for automated assembly. Typical applications for this connector series include automotive body electronics, infotainment, and other low-voltage signal circuits where a compact, vibration-resistant interconnect is needed.
The insulation material is polyamide PA9T, glass filled, rated UL94 V-0. This means the housing will not support combustion in a fire event inside an enclosure.
Tin is suitable for moderate mating cycle counts (typically 25-50 cycles) in non-corrosive environments. For higher cycle life or corrosive atmospheres, a gold-plated variant would be preferred. In practice, the 1.80mm pitch and tin plating limit continuous current to around 3-5 A per contact in a single-row configuration, but the exact figure depends on the terminal and ambient temperature.
