The devices that are "NRND" are the old non-RoHS (Pb) versions. We are not obsoleting the LP339-N, only the non-ROHS package versions.
Unless you have specific need for the old lead finish, then switch to the "new" RoHS compliant versions with the /NOPB suffix. These are electrically the same (same die, same testing), but have RoHS "green" compliant package materials.
So if you were ordering the LP339MX, you would now order the LM339MX/NOPB.
Note that there is a difference in the solder profiles for old Pb and newer RoHS, so manufacturing soldering reflow may need to be updated when switching to /NOPB.
