RoHS Compliance RoHS Compliant
Environmental protection legislation is changing the electronics market for all of us. We are committed to providing you with RoHS compliant products to satisfy these changing market needs.Our products do not contain lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls or polybrominated diphenyl ethers.

We have converted all product families to RoHS compliant assemblies. Part numbers will not change. As they are released, the first compliant lot numbers of each product family will be announced on our website. Our prototyping electronic assembly service is available with RoHS compliant processes. Click on the icon above to download a Letter of RoHS Compliance.
Frequently Asked Questions:
Q: What does Wavelength mean when listing a product as RoHS compliant?
A: First, all component parts used in our products have been certified by our vendors to be RoHS compliant. Second, all soldering and other manufacturing processes at Wavelength do not introduce non-compliant compounds into the product.
Q: Will parts with tin/lead solder still be available after the transition to RoHS compliance?
A: Only by special request. Wavelength is removing the lead from all products. If you have a special need, contact the sales department at sales@teamwavelength.com.
Q: How can I distinguish between compliant products and non-compliant products?
A: Since the part number will not change, the lot or serial number will indicate compliance status. The first compliant lot or serial number for each product family is included in the Certificate of Compliance on this web site. (See chart below.) In addition, the product web pages will be marked with the RoHS icon, and the products will be similarly marked.
Q: Will there be a cost impact associated with the change to compliant products?
A: No. There will be no price changes as a result of conversion to RoHS compliance.
