Good afternoon Joe,
I'm going to try and answer your question...
The CC364X denotes a high-yield version of an HP toner in this case it's 24,000 page yield.
I am not familiar with an HP SKU for CC364XC although some remanfactured companies have used a "C" on the end in my experience to note a compatible cartridge.
The CC364XD denotes a high-yield version sold as a 2-pack at more competitive pricing.
I hope this answers your questions. Feel free to let us know if we can do anything further to help.
Thank you!
