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 2). 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.

“Conflict Metals” Commitment
We at Stackpole Electronics, Inc. are joined with our industry in opposing the use of metals mined in the “conflict region”
of the Eastern Democratic Republic of the Congo (DRC) in our products. Recognizing that the supply chain for metals
used in the electronics industry is very complex, we work closely with our own suppliers to verify to the extent possible
that the materials and products we supply do not contain metals sourced from this conflict region. As such, we are in
compliance with the requirements of Dodd-Frank Act regarding Conflict Minerals.
