Earl, I read your question incorrectly. When you said equate to, I read that as in having a similar component, not as in being compatible with fluxes. I think the best answer is that it is something that needs to be tested on a case by case basis.

I'm sure the OSP chemistry is compatible - no kidding - with current flux chemistries or how could it work When we used "SealBrite" it was essentiall a flux. Does someone out there know the answer to my question concerning flux composition in terms of Jana's answer?
