15-Position Panel-Mount Housing for the Commercial .093" Series
The TE Connectivity 770103-1 is a 15-position receptacle housing from the Commercial.093" Pin and Socket series, arranged in three rows on a 5.03 mm pitch.
Sizing the Housing: Position Count and Pitch
At 15 circuits, this housing matches a 15-position BOM line. If your harness calls for 12 circuits, the 770099-1 panel-mount variant drops right into the same cutout pattern; the 770105-1 swaps the snap-in mount for a free-hanging (in-line) body, which changes the strain-relief approach on the harness side.
