Yes, the R0G bit is just a packaging code (R0 for reel which doesn’t matter unless you buy 10,000 of them, G for halogen free). Any 2 V zener will work here (1N4615, 1N4679, BZX55C2V0, BZX79C2V0, …) or if you cannot find 2 V anything from 1.9 to 2.4 V or so should be fine (and the diode will usually don’t do anything, it’s there’s to keep the CV to the chip within spec, in case you try to overwhelm the circuitry…)
EDIT: Added some alternatives.
