CEL Pb-free products have the same base part number with a suffix added. The suffix –A indicates that the device is Pb-free. The –AZ suffix is used to designate devices containing Pb which are exempted from the requirement of RoHS directive (*). In all cases the devices have Pb-free terminals. All devices with these suffixes meet the requirements of the RoHS directive. This status is based on CEL’s understanding of the EU Directives and knowledge of the materials that go into its products as of the date of disclosure of this information. Restricted Substance per RoHS Concentration Limit per RoHS (values are not yet fixed) Concentration contained in CEL devices -A Not Detected Lead (Pb) < 1000 PPM Mercury < 1000 PPM Not Detected Cadmium < 100 PPM Not Detected Hexavalent Chromium < 1000 PPM Not Detected PBB < 1000 PPM Not Detected PBDE < 1000 PPM Not Detected -AZ (*) If you should have any additional questions regarding our devices and compliance to environmental standards, please do not hesitate to contact your local representative.
