In my experience Alternator failures in modern applications come in generally a couple of flavours,
1) Clutch pulley drive or bearing failure:---- this doesn't seem to be a issue here.
2 )They run too hot which causes the solid state components and or the insulation on windings to fail:---- very likely the problem here. This weakness is ultimately resolved by redesign improving internal airflow and improving the design of the in built fan
3) Related to this failure mode is that they are under engineered for the task they are being asked to do. :---- also a likely the problem here. It is also usually resolved by redesigning the alternator.
Are the replacements identical or are they improved? that is a question I would be asking FCA.
