Direct answer
MC4 compatible connectors are PV DC connectors used for module, string and extension cable connections. Compatibility should be checked by connector family, contact size and cable range, not only by appearance.
Many after-sales problems come from mixing connector brands or using the wrong crimping process. We keep connector selection tied to cable size and project voltage.

Are all MC4 compatible connectors interchangeable?
No. Similar appearance does not guarantee safe mating. Connector family and manufacturer compatibility should be checked.
