Tube types


Hi all
My Octave HP700 pre uses, amongst others, a Telefunken ECC88. Can I use an E188CC? 
If not why?
Am I right in thinking the E88CC is far superior to the ECC88?

Thanks

Here ya go!
The 6DJ8 is a dual triode preamp tube. ECC88 is the European designation for this tube. 6922 and its European equivalent E88CC are premium versions of the 6DJ8. 7308 and E188CC and the CCa are super premium versions.  
@yogiboy  thank you. I wasn't aware of the CCa version. I see they're expensive!
