RS definition of RoHS Compliance:

  • The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
  • and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering

The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:

SubstanceConcentration
Lead0.1%
Mercury0.1%
PBB (Polybrominated Biphenyls)0.1%
PBDE ( Polybrominated Diphenyl Ethers)0.1%
Hexavalent Chromium0.1%
Cadmium0.01%
DEHP (Bis (2-Ethylhexl) phthalate)0.1%
BBP (Benzyl butyl phthalate)0.1%
DBP (Dibutyl phthalate)0.1%
DIBP (Diisobutyl phthalate)0.1%

The supplier of the item listed below has informed RS Components that the product is "RoHS Compliant".
