Does the Molex 2mm Dual Row Receptacle Have an Orientation?

If you have any doubts about whether the Molex 2mm Dual Row Vertical Receptacle has a specific orientation, please refer to the details below.

Based on the Molex datasheet — the answer is yes, this part does have a specific orientation.

The datasheet clearly highlights:

  • A Row A and Row B layout, with circuit numbering starting from Row A, Circuit 1 and proceeding left to right, as mentioned in the note:

“CKT LOCATIONS ARE NUMBERED FROM LEFT TO RIGHT WHEN VIEWING ASSY FROM TOP WITH THE GATE RECESS ON THE RIGHT AS SHOWN.”

This means the connector’s orientation is defined by the position of the gate recess — a molded feature that helps identify the correct alignment during PCB placement and mating.

Also, the housing recess is used for the packaging orientation.

Note that this orientation is not the same as electrical ‘polarity’. This connector is a passive device with no internal circuitry, and will not malfunction the same way a polarized device installed in the incorrect polarity will. The connector will function either way around, but Molex’s pin numbering only applies if the device’s orientation is correctly observed.
