Is FS-2 compatible with FS-22???

I cant find an answer anywhere!! :wall:
I am about to go to the hardware store and wanted to know if in case they dont have FS-22 fluorescent starters would an FS-2 work?

If memory serves, it should be OK but I am no electrician. If unsure, take the whole fixture to supplier and ask about the difference?

I have both of them in my fish junk drawer, so they must be interchangeable since I only use one kind of starter.
