Texas Instruments LM4562 NA vs LM4562NA/NOPB

[KKumar]

Hi, is there any difference between the TI LM4562 NA and the TI LM4562NA/NOPB?

It is to be used in a Elekit TU-8500's phono stage. The TI LM4562NA was highly recommended however Mouser only has the
TI LM4562NA/NOPB.

Thank you.

The NOPB presumably contains no lead (the heavy metal with chemical symbol Pb).
