RoHS Compliance

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, polybrominated diphenyl ethers or restricted phthalates.

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.

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.

EU RoHS versus China RoHS

What is China RoHS?
The Measures for Administration of the Pollution Control of Electronic Information Products (commonly known as “China RoHS”), was issued by the Ministry of Industry and Information Technology of the People’s Republic of China. It aims to restrict the use of toxic and hazardous materials in electronic equipment.

China RoHS affects all Electronic Information Products (EIPs) that are manufactured on or after March 1st, 2007 and sold into China.

What is an “Electronic Information Product” or EIP?
There is no broad definition of what encompasses an EIP, but the China RoHS explanatory note includes components as well as finished products. Any product listed in the Key Catalogue is considered an EIP.

Does compliance with the EU RoHS Directive, also mean compliance with China RoHS?
The China RoHS is similar to the EU RoHS in that it restricts certain hazardous substances in consumer products and in packaging materials. However, the China RoHS was developed entirely separately from the EU regulations. China RoHS includes automotive, medical devices, manufacturing equipment, components, electronics, radar equipment, certain raw materials, and packaging materials.

China RoHS does not acknowledge EU RoHS exemptions. Only those products which are added to the Key Catalogue are subject to material restrictions. If a product is not listed in the Key Catalogue, it is “exempted”. So China RoHS does not need to contain exemption rules, as exemptions are granted automatically unless being explicitly revoked.

How can I determine if a product is China RoHS compliant?
If an EIP does not contain any hazardous substances (Pb, Hg, Cd, Cr6+, PBDE, and PBBE) above the maximum concentration values, then the following symbol must be applied on the EIP or the product instructions.

What are the Maximum Concentration Values (MCVs)?
China RoHS provides for three different classifications for MCVs:

  • EIP-A Each Homogenous Material
  • EIP-B Metal Plating
  • EIP-C Small Components/Materials (generally less than 4.0mm3)

China uses the same MCVs as EU RoHS except for metal plating:

  • 0.1% for Pb, Hg, Cr6+, PBDE, PBBE
  • 0.01% for Cd

How do I know if a Wavelength product is China RoHS compliant?
Our products are labeled with both the RoHS and the China RoHS icons. If the China RoHS icon is not shown, the product is NOT compliant.

Additionally, in the table above, if the product is listed as COMPLIANT, then it complies with BOTH the EU RoHS and the China RoHS. If the product is listed as COMPLIANT BY EXEMPTION, then it is ONLY compliant with the EU RoHS, but not the China RoHS. Currently, only our thermistors fall into this category.

Please contact Technical Support if you have any questions concerning compliance.
