The Molex 1727620112 is a 12-position, dual-row plug housing from the Mini-Fit TPA2 series, on the standard 0.165" (4.20mm) pitch that defines the Mini-Fit footprint. The locking ramp fastening means the plug audibly latches into the matching receptacle housing, giving the harness builder positive retention feedback during assembly.
Contacts are not included. This is a housing only — you must source the matching male crimp terminals separately. The 12-position count and dual-row layout at 4.20mm pitch match the standard Mini-Fit TPA2 receptacle housing, so the BOM line check is straightforward: confirm the terminal part number for your wire gauge (typically 18-24 AWG in this series) and order those alongside this housing.
