How do you expect this forum to help?

You need to take this up with your supplier, if you think it's an unacceptable substitute

Or are you just asking what's the difference between STM32F205RFT6 and STM32F205RET6 ?

The answer to that is in the datasheet:

GAzen.1 · ‎2022-07-05

Yes i know that, i tell about the marking code device

GAzen.1 · ‎2022-07-05

i have a E on the component but a R on the label

Again, if you think your supplier has sent you the wrong part, then you need to take that up with them.

Was it a reputable supplier...?

Or, if your not sure about the markings, and want confirmation of what you think you're seeing, then you need to post some good, clear, in-focus pictures of what you have - we can't see it any other way!
