What the 0397199002 Is — a Cover Support, Not a Connector
The Molex 0397199002 is a Type Cover Support — a mechanical retainer or backshell used within a connector assembly, not a header or housing that carries contacts. It ships in Bulk packaging and belongs to the 039719 base product family. If your BOM line lists this as a connector, double-check: it is the secondary part that holds the wire-dress or shields the termination area on a mating interface.
Where It Fits and What It Mates With
The evidence identifies this as a Cover Support, not a connector. The base product number 039719 is shared with several Mini-Fit and other Molex power-interconnect housings. Verify fit against the housing part number on your assembly drawing before ordering.
