Richtek Date Code YMDNN

I didn't find how to decrypt the date code but I googled a little bit and I think the years are encrypted like this :
from 2010 til 2013 - letters from C til F
from 2014 til 2022 - numbers from 1 til 9

I hope it may be useful in order to avoid bad batches

Re: Richtek marking code

Hi friends, cant find this one...
G0=
If someone can help me, thanks in advance

Maybe too late, but...
RT3612EB 5V=
RT3612EG G2=
RT3613EE 8D=
RT3613EJ G0=
RT3614EE 7Z=
RT3614EJ [UNKNOWN]=

Pairs of ***2/***3/***4 maybe pin2pin compatible with each other. At least in sch text says PU3500 is RT3613EE (HS45A/HS55A NMD461 MB Schematics Document 2020-04 REV:0.1) but as fact on board is RT3613EJ (on quoted post photo).

Wouldn't it be fabulous if all Manufacturers would provide Decrypting / Decoding information available for Top Markings. The biggest challenge that I find is trying to decode various alpha-numeric date codes into an actual Date or Week of Manufacturer. Cross-referencing to YYWW from Richtek 7CX0A (for example).
