Part Numbering for SRAM Memory Integrated Circuits from Renesas

We often get questions regarding slight differences in part numbers on memory ICs from Renesas Electronics Corporation. Take for example the part numbers shown on this table (snip below).

As seen on the chart the parts are very similar, so what do the numbers mean?
R1RW0416DSB-2PI#D1
R1RW0416DSB-2PI#D0
R1RW0416DSB-2PI#B0

By consulting the SRAM part number guide from Renesas we can see that the difference in suffixes calls out the packing and environmental factors of the part, functionally they are the same.
