4-position right-angle header
The 1-179277-2 is the 4-circuit member of TE's Dynamic D-3200 single-row right-angle header line. Gold-plated mating contacts rated 600 V, 5.08 mm pitch, through-hole solder termination, shrouded 4-wall housing with detent lock and board lock feature.
Single-row selection within D-3200
The 1-179277-2's 4 positions are the only single-row count in the D-3200 right-angle header family; the 1-1871673-2 is a 4-position dual-row sibling at 2.50 mm pitch with tin-plated mating contacts, so the pitch and plating grade are the primary selection differentiators.
