Xbox play and charge USB-C vs Micro USB

I've inadvertently bought a play and charge kits with the wrong connector. I've got the micro USB connector ones rather than the USB-C one.

Are they the same thing apart from the connectors? I notice that the USB-C ones are out of stock everywhere, and one of the boxes has been rather prematurely re-used and I don't have it anymore, so I'm wondering if I just keep them and buy new cables?

Thoughts?
