Narrative:
Worked on aircraft X. Aircraft X had previous class 2 faults on elac (elevator aileron computer) 2 that was placed on MEL at a previous station. Per the microphone 77XXXXX; ZZZ requested that elac 2 be replaced. I proceeded to replace elac 2; printed out aircraft maintenance manual reference and made sure that the part is effective for the aircraft. However; I was unaware that there was supplemental information in the aircraft maintenance manual; stating that software configuration checks need to match for elac 1 and 2. I replaced elac 2 with the knowledge that it is effective for the aircraft. I am not qualified; so I asked somebody else to perform the cat 3 configuration test.I think the event occurred because the ipc (illustrated parts catalog) is unclear on the software modification information. Also; the supplemental information does not pop up when opening the manual for the right/right (repair and replace).provide training for personnel about elac software compatibility. Make the information a warning in red letters so the individual can read and understand that the software configuration cannot be different between elac systems.
