Hi Paul -

We asked this same question of our connector suppliers about a year and a half
ago.  We also asked the question of compatibility with bare copper (for OSP
coated boards).

Both of the responding suppliers were able to tell us that they had performed
Bellcore outdoor environmental testing on their products using these finishes,
and passed the test series.  The specimen reportedly had heavy levels of
"corrosion" buildup visible where the pins entered and exited the plated thru
holes.

I was never able to get a fully detailed report or photos to be able to
differentiate between finishes.

Would recommend you get with applications engineering at your supplier to see
what data they are able to provide, first hand.

Regards - Kelly
