What Numbers Have to Match on New ECU

[ata14]

Hi, I am pretty sure that I have a bad ECU so I am going to replace it anyways. My question is, what numbers have to match? On my old ECU the number is 5269730.

I looked at some ecu's on ebay, and a lot of them say that they would be compatible with my car (95 Eagle Talon ESI, with 2.0L DOHC manual), but the last 3 numbers are different.

For example:
95 1995 96 Eagle Talon FWD Transmission Computer ECM ECU Brain Box 5269574 | eBay

Let me know what I should look for when I am buying a new ECU. Thanks in advance!

Any na ecu from a 95 to 99 gs esi manual will work
