4.20mm pitch, 2-position header for wire-to-board
The 1724470602: This is a 2-position, dual-row header from the Molex Mini-Fit Jr 172447 series, with a 4.20mm mating pitch and 4.20mm row spacing.
Tin plating and current rating by wire gauge
Both the mating contact and the solder post are finished with 100.0µin of tin over brass. Tin is a cost-effective finish for moderate mating cycles (50–100 mates) in controlled environments; it is not recommended for frequent disconnect or corrosive atmospheres. The current rating is not a fixed number — it varies with the wire gauge of the crimp terminal used in the mating receptacle. For a given wire size, the Mini-Fit Jr terminal datasheet provides the derated current at the operating temperature.
Board-to-cable style, mates with Mini-Fit Jr receptacles
The connector style is Board to Cable/Wire, meaning this header mounts on the PCB and mates with a crimp-terminal receptacle housing.
