If you have received the Molex connector (part number 5031491200) and noticed small burrs inside the connectors, please see the clarification below:
After consulting with Molex, it has been confirmed that the Molex manufacturing plant has concluded based on the Molex Cosmetic Specification that these are burrs and classified as Class C surface.
Class C surfaces are non-decorative, meaning the burrs are not visible when the parts are mated and have no impact on the connector’s functionality, fit, or form.
Molex has assured us that the connectors are fully usable, and their performance is not affected in any way.
