How are RoHS compliant electronic components ordered - is there a standard code used to differentiate them from traditional lead (Pb) containing devices?

Unfortunately, there is NO component identification standard. Some manufacturers have generated new ordering codes to designate RoHS compliant product, others employ temporary designators to be utilised during FAB transition, while several IC manufacturers have openly stated there will be no planned component ordering modifications.

This chaotic scenario stimulated the development of CASEC, following customer requests for impartial guidance on a largely ignored aspect of lead-free manufacturing - components. The service provides clear examples of the diverse solutions available on a manufacturer-by-manufacturer basis, ensuring identification is clearly understood. This is particularly important when parallel manufacturing is necessary, ensuring non-compliant components are not allowed to cross-contaminate RoHS compliant substitutes.
