RoHS Status Report
Updated: September 2009

RoHS Part Search
RoHS directive became effective July 1, 2006. This directive requires that any new electrical and electronic equipment put on the market after that date in the European Union may not contain or severely limits any of the six substances: (lead, cadmium, hexavalent chromium, mercury, PBB, and PBDE), unless the equipment falls outside the scope of RoHS or unless one of the RoHS exemptions is satisfied. NKK's had implemented the following to support that effort, prior to the July 1 due date:
  1. All standard switches and accessories manufactured during April of 2006(date code 64) or later are RoHS compliant.

  2. Most of NKK's parts were RoHS compliant from the outset. Full compliance has required conversion of the remaining parts by removing lead (with some exceptions – See #7), cadmium (with some exceptions - See #8), and hexavalent chromium from the manufacturing process.

  3. Information about the lead-free and RoHS compliant status of most of NKK’s parts is available on NKK Switches web site ( http://www.nkkswitches.com ). The remainder can be requested from the factory. Importantly, the web site provides the lead-free solder profiles for the listed parts.

  4. For converted parts, NKK has assigned new part numbers. The new part numbers will contain a “-RO” suffix to signify RoHS compliance.

    1. Ex: Conversion of a non-complaint part: BB15AH-FA to a RoHS complaint part BB15AH-FA-RO.

    2. Update: The "-RO" suffix is being phased out with April of 2006 identified as the date of complete compliancy of all manufacturing. All standard switches with date code or later are compliant. All standard accessories manufactured on or after that date are compliant.

  5. Parts that were RoHS compliant from the outset will not be given new part numbers.

    1. Ex: A12AP has always been compliant so the RoHS compliant number remains A12AP.

  6. NKK welcomes written requests for RoHS compliant status of NKK’s parts. Upon written request, NKK will issue a Certificate of Environmental Compliance for the switch series. These series wide C oc C's are also posted on the NKK Switches' web site ( http://www.nkkswitches.com ). It will list the part number attributes, the compliancy date, and any exemptions associated with the part number.

  7. Some parts do use the Lead in Copper alloy exemption, Annex #6, to be RoHS compliant. That exemption will be listed on the certificate of compliance.

  8. Some parts do use the Cadmium plating on contacts exemption, Annex#8, to be RoHS compliant. That exemption will be listed on the Certificate of Compliance. Cadmium is more resistant to pitting from electrical arching during switch actuation. Even though this exemption exists, NKK will continue the process of removing cadmium from all its products.

  9. On 1 April, 2008 the European Court of Justice made a judgment to annul the RoHS exemption of “Deca-BDE in polymeric applications” starting 1 July, 2008. RoHS compliant parts sold by NKK Switches prior to the anulment are still in compianc. None of the switches and accessories manufactured by NKK Switches contain Deca-BDE.

  10. Homogeneous percentage, ppm, substance weight, etc of non RoHS related substances are proprietary information. For RoHS related substances the certificate of compliance will declare that the six RoHS substances, if present within the part, are below the max ppm requirements of RoHS. Full material declarations are not required for RoHS compliance.

  11. NKK is also willing to provide the information necessary for end product manufacturers to fulfill their China RoHS requirements. This information can be found on NKK Switches' web site( http://www.nkkswitches.com ) or by contacting the factory.

  12. NKK will not accept returns (including stock rotations) based solely upon lead-free/RoHS non-compliance.

  13. Anyone who has any questions should feel free to call or e-mail Engineering at 480-991-0942 or engineering@nkkswitches.com .
