What is the difference between U.FL, UMC and UMCC connectors?

What is the difference between the U.FL, UMC, UMCC and other similar looking SMT coax connectors?
Are they mating-compatible?

Hi Beunos,

U.FL & UMCC - Both are miniature RF connectors for high frequency signals upto 6 GHz. These connectors are used in the applications where the space is of critical concern.

But can we plug them together?
I didn't ask what is common between those 3 types, but what is different?

Yes. You won't need to ask if you read the datasheets thoroughly.

Pls see the datasheets for the same...
