Leaded components in a no lead process

Expert Panel Responses
It isn't going to be an issue of lead contamination so much as it might be an issue with reliability. We have seen issues with cracking when the lead gets above .4% in the solder joint. Our suggestion would be to wait to go to lead free until you have all leaded components switched.
