Hello C James, 



Thank you for contacting ON Semiconductor. 



I have no information about the PCN saying that mentioned packages are

not backward compatible. 



ON has conducted reflow tests of Pb-free parts using Pb-containing

solder reflow temperatures and processes to simulate this condition.

Tests have been conducted at 210 to 230?C and results show that there

are no solderability issues. This does not apply to BGA, bumped die or

Flip Chip devices; if the parts are Pb-free they need to use a Pb-free

reflow process: http://www.onsemi.com/PowerSolutions/content.do?id=1282

Subject: Pb-F 



Description of customer request: 



Have you issued a PCN saying your Pb-free TO-3 and TO-92 packages are

not backward compatible and should be used for Pb-free soldering only?
