18-position three-row plug for power harnesses
The 176280-9 is an 18-position plug housing from TE's Universal Power series, arranged in three rows with a 0.156" (3.96mm) pitch.
Pitch and row spacing for footprint planning
The 0.156" (3.96mm) pitch and 0.181" (4.60mm) row spacing define the mating footprint. That's a wider pitch than the 0.098" (2.50mm) on the single-row 1-1376477-6 sibling — the 176280-9 suits power distribution where wider traces and higher current per circuit are needed.
