I don't believe the PIC18F4620 and the PIC18F2331 are pin for pin compatible. If you already have a PCB made then the new part probably won't fit. The PIC18F2431 is the step up from the 2331 in memory. The PIC18F2525 might match up pin for pin but you definately need to check.

RAM capacity isn't your problem. ROM capacity is. See the above comments by several people.
