The 643405-1: The tin finish is well suited for moderate mating-cycle duty (50–100 cycles typical) in equipment that is assembled once and rarely field-serviced. The UL94 V-2 nylon housing provides basic flame retardance for general-purpose applications.
The insulation height of 0.550" (13.97 mm) leaves clearance for mating connectors and wire dress above the board.
Tin on both the mating face and the solder tail — no gold or precious-metal plating option is listed for this position count in the series.
