The 0022288023: The mating contact surface carries 15.0 µinch (0.38 µm) gold over nickel — this plating grade is rated for repeated mating without the fretting corrosion that tin contacts exhibit in low-energy signal circuits.
Yes, it carries ROHS3 Compliant status per Molex's compliance documentation.
This unshrouded header mates with KK254 series crimp receptacle housings (e.g., 002202 series) or IDC sockets that accept 0.100" pitch, 2-position male pin headers.
The 3-position sibling 0022288032 uses the same pitch, orientation, and plating — if your circuit count allows an extra position, it is a drop-in for the same board footprint with one unused pin.
