RoHS Compliance

Stackpole Electronics has joined the worldwide effort to reduce the amount of lead in electronic components and to meet the various

regulatory requirements now prevalent, such as the European Union’s directive regarding “Restrictions on Hazardous Substances”

(RoHS 3). As part of this ongoing program, we periodically update this document with the status regarding the availability of our

compliant components. All our standard part numbers are compliant to EU Directive 2011/65/EU of the European Parliament as

amended by Directive (EU) 2015/863/EU as regards the list of restricted substances.
