Cirrus Logic part numbering "R" suffix callout

On Cirrus Logic parts they will have the letter “R” at the end of some of their part numbers. For example: CS8900A-IQ3Z and CS8900A-IQ3ZR
There does not seem to be any indication on the data sheets for the R call out.
According to Cirrus Logic this calls out Tape and Reel. There is no functional difference.

They did give us a piece of information stating it.

The nice thing is this R callout will be for all of their parts. If their is an R suffix at the end of the part number is will be Tape and Reel
