12 circuits, 3 rows, 6.50 mm pitch — the housing that holds the power pair
The 1747363-1 is a 12-position, 3-row receptacle housing from TE's Dynamic D-3800 series, on 6.50 mm pitch with 5.20 mm row spacing. Three rows mean the mating header must also be 3-row — a 2-row header won't align. This housing ships empty — contacts are ordered separately. The latch lock on the side snaps into the matching header for vibration-resistant retention without screws or clips.
Mating header and compatible contacts — what bolts in
The mating header for this receptacle is a Dynamic D-3800 series pin header with 12 positions in 3 rows, 6.50 mm pitch, and the matching latch lock feature. Confirm the header part number against your BOM — the row count and latch are non-negotiable. The female socket contacts for this housing are crimp terminals from the Dynamic D-3800 contact family.
