The 6-103673-6: With 17 positions loaded in a single row, the connector spans 1.700" (43.18 mm) along the board edge, plus the shrouded housing overhang.
Current and contact interface
Mechanical retention and keying
A keying slot in the shroud prevents mismating with receptacles that lack the matching key — a practical safeguard in multi-connector panels where identical-looking headers sit side by side.
RoHS compliant per current directive.

For applications requiring gold-plated mating contacts and the full 17-position count, 6-103673-6 is the correct choice; the tin-plated sibling suits lower-cycle-cost designs where corrosion resistance is less critical.
