Compatibility between Flash

[diyre]

Good evening everyone, a technical question that goeth about my head.
If I have a flash AM29F400BT -70SE, according to the dataseet, the T is top sector.
Would support AM29F400BB -90SE ??
According to that, the Sector B is Botton, but the capacity is the same and the pinout too.

Are compatibles at read level. Maybe you have problems if you try to program OBD after swap. But for repair an ECU with broken flash IC is not problem swap, but need to be programmed before soldering to ensure you have no trouble after.

Thank you very much for your reply, that is if one takes the ecu BT, I can read it for OBD and programmer, if BB could only lead by programmer when implementing OBD could not make any reading and writing.
