The K103M-R replaces the K103M
The K103M-R is RoHS compliant. It contains less than the Maximum Concentration Values (MCVs) for Lead, Mercury, Cadmium, Hexavalent Chromium, PBB and PBDE per EU directive 2002/95/EC. The following RoHS exemption applies: Lead as an alloying element in copper containing up to 4% (40000PPM) lead by weight.
All materials contained in the "-R" version are identical to the materials contained in the obsoleted part. Only the "-R" suffix was added to signify RoHS compliance.
