Lead Free Components
(OP)
We're in the process of converting our components to lead free. Does anybody know the best site regarding lead free components that can help me to start working with our part numbering system? Do I really have to create new parts numbers for all lead free components? I'll appreciate any help. thanks

may be it is your answer.but i donot understand your question.

With a 34C temperature difference for a true lead-free assembly process (so are TI's parts forward compatible?), component packaging and possibly other aspects of certain parts will have to change too. So look for another round of PCNs that focus on the epoxy/filler that's used for plastic packages since current packaging doesn't stand up to the higher heat. Maybe then TI will change part numbers...
By the way, it's not just lead that's the problem...be sure you understand the EU's complete requirements regarding shipments in to/within the EU as of July 1, 2006.

Thanks for the info. Do lead free components have identification when they are already in the power supply? Like if lead free resistors have a different color body part same as with the capacitors. And how about ICs do they have different logo on the package itself to identify lead free?
RE: Lead Free Components
But you raise an interesting prospect. Wouldn't it be nice if mfrs could put something like a "green" symbol on "green" parts? That's just too pie-in-the-sky, I'm afraid. It doesn't buy them anything and isn't useful for their marketing either (and admittedly is of little use by their OEM customers; and what use there would be is limited to between now and July 1, 2006). There are more important identifying marks that don't fit on current parts due to size and cost...SMT resistors/caps/SOT-23 size parts have minimal or no marks whatsoever - you can't even tell who made many 0603 or 0805 caps, or what the value is! Same goes for many parts, I'm sure, you're seeing in your power supply. So I hope you have the BOM for it - that's the place to start.

The way in which we are attacking this is to have a PBF (Pb Free) in our AVL. When we go to PBF we tell the vendors that they can only purchase PBF parts in our AVL.
Creating a new PN causes a load of havock since the design database must also be updated (1 Million parts!). By using the method above, only newer designs get updated (which is how the PBF standard is worded).
