Only 2 of the 3 positions are loaded with male pins, a common configuration for cost-sensitive applications where the third position is a keying or polarization feature. The tin-plated contacts suit moderate mating-cycle duty in general-purpose and industrial environments.
The 641937-2 is a 3-position header with 2 positions loaded, while the 641937-3 is a 3-position header with all 3 positions loaded. The housing and pitch are identical; the difference is the number of populated contacts.
Yes, the 641937-2 is ROHS3 compliant per the current directive.
