There’s NO difference between those two SMD Comm X5R series parts: C1206C226M8PAC7800 and C1206C226M8PAC from KEMET ?
Both are referring to C1206C226M8PACTU indicating MLCC CAP CER 22µF 10V X5R 1206.
In the datasheet there’s only the reference for 7081 as Packaging C-Spec Ordering Option for 7" Reel/2mm pitch vs Unmarked allowing for double the packaging quantity of capacitors on a given 7 inch reel size with an order quantity of 2000 pcs for the complete Tape & Reel.
