Hello @tnburrow and welcome to the Digi-Key TechForum,
The T&R calls out the packaging. It stands for Tape and Reel. It just means that it comes in reel packing. The part with out the “R” is bulk packaging. The parts are the exact same. Tape and Reel is often used in large production quantities, but you can easily pop the parts out of the Tape and Reel and use them like bulk packaging if you are only needing a few for hand production. Here is a good explanation on Tape and Reel if you are interested.
