Catalyst recognizes the need for manufacturers to quickly and easily discriminate between RoHS and non-RoHS-compliant devices. We meet this requirement through the use of a unique package ID to denote RoHS-compliant packages. Each package has one ID for conventional non-RoHS-compliant versions and a separate ID to denote RoHS compliance.
We provide further traceability of the actual lead finish used on RoHS-compliant parts. When NiPdAu lead finish has been used, “-G” is added after the part number. RoHS-compliant parts that do not have the “-G” after the part number have matte-tin lead finish. An example of this number convention is given at the bottom of this page.
