CHIP DIODES Bourns Manufacturers Representatives Corporate Distributor Product Managers Americas Sales Team Asia Sales Team Europe Sales Team January, 2008 Non-RoHS Compliant Diode Part Number End of Life Bourns has successfully provided RoHS compliant diodes with part number suffix “LF” to our customers since January 2005, with the result that the majority of Bourns customers have already switched to RoHS compliant part numbers during the past 3 years. Due to lack of orders for SnPb models over the past 12 months with customers preferring to use RoHS compliant parts instead, effective immediately Bourns will no longer accept orders for diode part numbers using SnPb termination plating (without “LF” suffix). The affected Bourns® part numbers include the following part number series: CD214A-B Series CD214C-B Series CD214A-T Series CD214C-T Series CD214B-B Series CD216A-B Series CD214B-T Series CD1607-B Series To avoid customer production down time, Bourns is strongly urging and requesting that customers using Bourns® diode part numbers (without suffix “LF”) switch to alternative lead free part numbers using the "LF" suffix with 100 % matte tin plating. The RoHS compliant Bourns® diode part number with the "LF" suffix is backward compatible to the SnPb lower temperature 235 °C ~ 240 °C solder reflow process. I have attached solder bath temperature data to support the backward compatibility. ESD0804 Bourns Inc.
