GE Fanuc PLC Spare parts

[kietntdq]

Dear all
Anyone can help me to clarify the below:
Recently, we purchase some spare parts but the Model number is not the same with current system parts (a little bit difference)
The difference as below:

IC693CHS391 and IC693CHS391 N
IC200CHS022 and IC200CHS022 L
IC698CHS009 and IC698CHS009 A
IC697ACC644 and IC697ACC644 A
IC200CHS001 and IC200CHS001 N

So please help me to clarify the deviation of model.
Are they compatible with existing system ? Can I simply replace without any other modification ?

Thanks

The letter at the end of those part numbers designates a revision of the hardware. There will be no difference in their operation or configuration.

If there are two letters it usually is that one letter is firmware the other hardware.
