I don't think there is any environment where lead free is as good as "real" solder.

When you say "high vacuum" do you also mean low gravity? i.e. space? If so my understanding is when the tin whiskers short out the vapour does not settle down but instead forms a conductive plasma.

Or are you talking about some terrestrial use of high vacuum?
