Confused on tube types. Can someone help me out?

My amplified needs a tube that is 12AU7 compatible. Is the SIEMENS CCA a 12au7 tube? I can't find any information.

If it isn't 12au7, than what is it? Someone please help me.

The "CCA" designation is a 6922 (6DJ8, 7308) type tube. NO you can't use it.

My favorite 12AU7 is a Mullard CV4003:

Of course, there are many options.
