The solder tails are 0.120" (3.05 mm) long, which fits typical 1.6 mm thick PCBs with enough protrusion for a reliable fillet.
ROHS3 compliant, sold in bulk packaging.
The only difference between this 3-position header (0022284034) and the 4-position sibling (0022284035) is the pin count — everything else (pitch, plating, housing material, termination style) is identical. For a direct form-fit-function swap, stick with the exact position count your mating half requires.
The mating half must have a full shroud to protect the exposed pins.
