Anyone tried using an LM4871 instead of an LM9022?

TI confirmed some time ago that these are actually the same chip but with a different marketing spin, e.g. see  https://e2e.ti.com/support/power-management/f/196/t/289255?lm9022-similar-solution-

Has anyone actually used one of these in anger in place of an LM9022? (as opposed to just theorising about it, that is...)

Just wondering...

Pharma Nick and I have a trial planned but we are a little while from making it up and testing it.

As I'm making up 3 of those VFD about clocks at the moment, I might give a LM4871 a go (although I have enough LM9022s)... I've done a full Farnell BOM for all the bits... a few of the original parts are no longer manufactured, so I've selected replacements (e.g. for the LM9022)

Just to confirm that as expected, the commonly available LM4871 works perfectly as a replacement for the discontinued LM9022. They are, after all, the same device but with different labels...
