15 Circuits, 3 Rows at 4.14 mm Pitch
The 770190-2: This is a 15-position, 3-row header from the Mini-Universal MATE-N-LOK series, on a 4.14 mm pitch. The 3-row arrangement means the mating receptacle must also be a 3-row, 15-circuit housing; the row spacing is 4.14 mm as well, so the PCB layout is a clean 3×5 grid.
