Board Layout Fit: Pitch, Positions, and Footprint
The 4-647168-0: Surface-mount solder tails: the SMD termination keeps the component on the same side as the header body, which simplifies the reflow profile and frees the opposite side for passives.
Tin-plated solder posts: the tin finish on the termination side matches standard lead-free solder processes and provides a reliable intermetallic bond.
Locking and Environmental Ratings
Friction lock on the shroud — the mating receptacle clicks into the single-wall shroud and resists vibration-induced disconnect without a secondary latch.
ROHS3 compliant: the part meets the current EU RoHS exemption rules.
