Chemistry selection

Dear all,

In october 2012 I have asked wich ID chemistry I do select for a Samsung SDI cell ICR18650-26F.

        e2e.ti.com/.../219226

The aswer was ID0192, the ID1165 is for a special case.

Now I see in "sluc138cw.zip --> chemistry_selection_table.xls"  that the ID0192 is obsolete and replaced with ID1165.

My questions :

1) Why the ID0192 is now obsolete?

2) Is there a big difference between this two Chemistry ID?

Thanks for your answers and best regards
