The 15 µinch gold plating on the mating face handles moderate mating cycles — think 50 to 100 mates in a clean environment — without the fretting corrosion you'd see with tin on tin in a high-vibration board. The tin-lead post finish (100 µinch) is a legacy solder alloy; confirm your assembly line's compatibility with lead-bearing solder. The insulation height of 0.090" (2.29mm) gives clearance for routing traces under the header body on the board.

Frequently asked questions
Is 4-103185-0-33 shrouded or unshrouded?
Unshrouded — the pins are exposed with no plastic shroud around them. The mating receptacle must provide its own alignment and polarization.
