The 0022182031: Board hooks on the housing lock the part into the PCB during wave solder, taking shear off the solder joints when the cable is tugged or the board is handled.
Push-pull fastening with no secondary lock means it's best in low-vibration environments or where the harness is strain-relieved externally.
The exact mating part depends on your orientation and mounting — typically a Molex 6373 or 6410 series header with matching circuit count and pin length.
Yes, it carries ROHS3 compliance, meeting the latest EU restriction levels.
