Question What's the difference between Crucial's CB8GS2400 and the CT8G4SFS824A DDR4 - 2400 SODIMM RAM's?

Oct 27, 2020
Recently I ordered the Crucial CT8G4SFS824A 8GB DDR4 - 2400 PC4 - 19200 CL-17 SODIMM RAM from Amazon India. But I don't know why I received the Crucial CB8GS2400 instead of that. Although when I saw the product reviews for CT8G4SFS824A, many others have received the Crucial CB8GS2400 instead. Also, when I checked for the compatible RAM for my laptop HP Pavilion 15-ck069tx on Crucial's Official website, I found the CT8G4SFS824A and the CB8GS2400 was not even on the list. It didn't even appear when I searched it under the "Find Product" section on Crucial's Website.
Please if anyone has information about Crucial memory products, and why the CB8GS2400 is not showing on their website (maybe it's EOL for this product I don't know), and what's the difference between the two then help me to make any further decision, whether I should return it or keep it. Also, I guess the "CB" stands for Crucial Basics but I don't know whether it's genuine or not.
