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:
-
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 #8), cadmium (with some exceptions - See # 9), and hexavalent
chromium.
-
Information about the lead-free and RoHS compliant status of most of NKK’s
parts is also available on NKK’s web site (http://www.nkkswitches.com
). Importantly, the web site provides the lead-free solder profiles for the
listed parts.
-
For converted parts, NKK has assigned new part numbers. The new part numbers
will contain a “-RO” suffix to signify RoHS compliance.
Ex: Conversion of a non-complaint part: BB15AH-FA to a RoHS
complaint part BB15AH-FA-RO.
-
Parts that were RoHS compliant from the outset will not be given new part
numbers.
Ex: A12AP has always been compliant so the RoHS compliant
number remains A12AP.
-
NKK has been building RoHS compliant inventory for many of its converted part
numbers, but many of the converted parts may have fairly long lead times. If
RoHS compliance parts are required, it is important to be sure to use the
compliant part number on the purchase order and to be sure that the lead time
has been clearly established.
-
Although NKK’s new production is RoHS compliant, NKK will continue to ship
pre-conversion inventory, while inventory exist, unless RoHS compliant parts
are clearly specified on the customers purchase order. (Refer to #12 for return
policy)
-
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 specific part numbers that are RoHS compliant. It will list the part
number, the compliancy date, and any exemptions associated with the part
number.
-
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.
-
On October 21, 2005, the Commission of European Communities issued its decision
to expand the exemptions to RoHS to permit, among other things, the use of
cadmium in electrical contacts (Annex #8). By virtue of this decision, all of
NKK's switches are now RoHS compliant with respect to cadmium for the duration
of the exemption, which could be as long as four years. That exemption will be
listed on the Certificate of Compliance. Even though this exemption has become
effective, NKK will continue the process of removing cadmium from all its
products.
-
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.
-
NKK is also willing to provide the information necessary for end product
manufacturers to fulfill their China RoHS requirements.
-
NKK will be unable to accept returns (including stock rotations) based solely
upon lead-free/RoHS non-compliance.
