Difference between OP97EPZ and OP97FPZ

Hello

I was going to get OP97 for an educational tutorial but then realized there are multiple versions available on sites like Digikey.

There is a substantial price difference between OP97EPZ and OP97FPZ but I couldn't find any difference in parameters in the data-sheet.

Does anyone know what is the difference between the two?

Best regards
