Does iPhone SE use the same case no matter which generation?

IPhone SE will it use the same case no matter the generation or have some of the features changed enough to require the specific generation in order to fit the phone? I’m truly sorry I’ve had to ask such a ridiculous question but it seems I’m unable to find the answer myself. I tend to make things so much more difficult than they are and I see right passed it.
