Hi, I'm trying to replicate the following circuit diagram, but I can't seem to find any sites/stores that are still selling the ceramic filter that they use (SFZ455F), so I was just wondering if its possible to replace it with some other ceramic filters.

And just another question, what does SFZ actually mean? I've tried googling for the datasheet and I just can't seem to find any revelent stuff.
Thanks in advance.
