all dseries piston ring the same?

are all d series piston rings the same
i need to get some rings for my pm3's and i wanna know if i can just order z6 rings or should i get the d15b7 rings?
majestic honda has diffrent part number for the two but every other site i have tried they are the same
only reason i ask is its cheaper to get rings and bearings for the z6 then just getting bearings and buying rings seperatly
