The 1724470604: This is a 4-position, dual-row through-hole header from the Mini-Fit Jr 172447 series, with a 4.20mm pitch that sets the board footprint and the per-contact current ceiling — the current rating varies by wire gauge on the mating side, so the limiting factor is the terminal and wire, not the header pin itself.
The housing is molded from UL94 V-0 rated PA66 nylon, which means the material stops burning within 10 seconds after the flame is removed — required for equipment that must pass flammability testing under UL 60950 or IEC 62368. Glow wire compliance means the connector passes the IEC 60695-2-11 glow-wire test at 750°C — a safety requirement for appliances and telecom gear where a hot component could rest against the connector housing.
