Wearnes Cambion WEEE and RoHS Statement

Wearnes Cambion is making every effort to meet our customer’s demand for lead free products to meet the WEEE 2002/96/EC and RoHS 2002/95/EC directives

Definition of "Lead Free"
Wearnes Cambion have adopted as it’s standard the Restriction of Hazardous Substances directive generally known as RoHS 2002/95/EC Directive

Status of product families
None of our components contain any of the following materials and it is our company policy not to introduce them into new designs.

Polybrominated biphenyls (PBB)
Polybrominated diphenyl ethers (PBDE)
Hexavalent chromium
Mercury

Leaded and Cadmium containing materials or material finishes will continue to be offered to customers supplying products into market areas exempted from the RoHS regulations

Pin and connector products currently offer lead free alternatives in most cases. Where no current alternative is available an additional plating specification will be offered. This is expected to be complete by late 2004

For products offering mixed plating specification a new part numbering system is to be introduced (see sheet 2) which shows both materials. Allowing customers engineering departments to specify both lead and cadmium free products.

As for our coil product range components that are already lead free there will be no change to the part numbering system. Where both Lead Free and Leaded components are offered then a new part number will be issued to the Lead free component. It is anticipated that all Cambion coils will be available with lead free alternatives by late 2004.

For custom products please contact our engineering department to discuss your requirements.

Due to new legislation due to come into force (July 2006) regarding the use of Cadmium, some part numbers will have to be amended slightly.

Note that all the existing Cadmium parts will still be available, with no changes to the part numbers, as Cadmium will still be allowed in some applications.

Alternatives to Cadmium are available, Nickel or Zinc would be the obvious ones, but any finish could be accommodated. It shall be the Customers responsibility to ensure that the alternative finish is suitable for their application, Wearnes Cambion will support technically as requested to achieve a mutually beneficial solution.

Most parts can just have the new finish code substituted for the –07 Cadmium code, such as 350-1300-02-07-00 plated with Nickel, would become 350-1300-02-02-00.

Other parts, assemblies, do not specify the Cadmium finish in the top-level part number, such as 570-1945-01-04-19. This has an Electro-tin plated terminal, and a Cadmium stud.

It is proposed that the 0 of –04 is used to signify the stud finish on none Cadmium plated parts only.

For instance, if Nickel were required on the stud the above part number would become 570-1945-01-24-19. Nickel being finish code –02, you drop the 0 to leave 2, then put that into the top level part number.

Other examples would be as follows:-

-21 Nickel stud, Silver terminal

-23 Nickel stud, Gold terminal

-24 Nickel stud, Tin terminal (as above)

-91 Zinc stud, Silver terminal

and so on.
