Notes: 

1. Part labels are RoHS compliant by exemptions 7(a) and 7(c)-1 as listed. Solder is 93.5Pb5Sn1.5Ag at a higher melt point than the Pb-free version.  For use for optimum low temperature performance, where resistance to higher temperatures may be required and for applications where requalification with different solders is not an alternative. 

2. Please add the suffix “N” to the part label for RoHS complaint by exemption 7(c)-1. Example: TK95F103VN. Solder is 97SC Pb-free. 

*Note: Both parts are classified RoHS compliant.
