Sumida RoHS compliance product: Non-intentional containing of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBB) and polybrominated biphenyl ethers (PBDE) in the product do not exceed the below threshold.

Cadmium: 0.01% wt (max. concentration by weight in homogenous materials)
Lead: 0.1% wt (max. concentration by weight in homogenous materials)
Mercury: 0.1% wt (max. concentration by weight in homogenous materials)
Hexavalent Chromium: 0.1% wt (max. concentration by weight in homogenous materials)
PBB: 0.1% wt (max. concentration by weight in homogenous materials)
PBDE: 0.1% wt (max. concentration by weight in homogenous materials)
* Deca-BDE is included in PBDE.
* The use exempted from RoHS Directive is excepted.

FAQ:

  1. What is the best preservation condition for keeping the RoHS compliant product?
    The preservation environment must be controlled to prevent any caustic substance/effect (including airborne) or dew condensation. The expected ambient temperature should be between 5 and 40° C and relative humidity of 20 to 70%.
  2. Are there any differences between Lead Free products and RoHS compliant products?
    Previously listed "lead free" products were studied and considered compliant, in regards to lead content only for lead-free soldering of terminal connection, case, and hoop. At that time, Cadmium, Mercury, Hexavalent chromium, PBB, and PBDE were not studied. So we can not say "lead free = RoHS compliance". In fact, only a few products reviewed their constituents on the six hazardous substances and eliminate them.
  3. When is the expected date of full conversion of Sumida products to RoHS compliant products?
    After January, 2006, SUMIDA only manufacture RoHS compliant products.
    NOTE: Regarding customized products, we will follow the date of specific customer requirements.
  4. How can customer distinguish the RoHS compliant devices from the non-compliant parts?
    SUMIDA standard products (S-074-XXXX specification sheets): A RoHS logo will be added on specification and on the reels & boxes.
    Customized products: We basically change the part name in conversion from lead free to RoHS compliance. Actually, we follow the customer’s requirement.
  5. Can customer order those non-compliant RoHS products?
    SUMIDA does not manufacture non-RoHS compliant standard products (S-074-XXXX) after January, 2006. Regarding customized products, when non-RoHS compliant products are needed by all means with products having you place an order conventionally, we shift it to customized products handling and the present production is possible. It becomes the other controlled production as non-standard products.
