tube question

I just got a preamp that uses a 5y3WGTA tube. I'd like to experiment with some other tubes. When looking at possible tubes, can I use any 5y3 tube or must they have the WTGA designation as well?

Sorry for such a newbie question.

Thanks.

The 'W' in WGTA indicates it's a ruggedized military version.

I have seen the tube substitution handbook from the above link. Interesting read.
