Hi Mauricio
D1RP3LL is when you are buying a 2.5k EPS expansion for the first time.
D0V5KLL is for reinstating support and subscription (S&S) when this has been allowed to lapse.
So for example two years ago you may have purchased D1RP3LL and missed paying the invoice on the 2nd year S&S (which is an 'E' part by the way). To get back to having S&S entitlements you would purchase the support reinstatement part D0V5KLL.
I hope this helps to clarify those two parts.
