Difference between TPS5633PWP and TPS5633PWPR

I have an old design and TPS5633PWPR appears to be obsolete and I’m told that TPS5633PWP is a direct substitute. Both products point to the same generic product spec, so I can’t tell what the actual differences are between both chips, surely it’s not just a name change.

Any guidance would be appreciated.
