Are those the same reasons for including servers and storage? I suspect a lot of RoHS compliant parts will make it into exempted equipment just because of availability and difficult quality control but I would not expect this to cause any significant problems. I have not seen an exception for CdS photocells although many manufacturers have petitioned for one. Unfortunately there are a lot of esoteric applications for which they have no substitute short of complete reengineering and in some cases not even then. I expected at least the hermetically sealed ones to be exempted. http://sales.hamamatsu.com/en/products/solid-state-division/compound-semicond uctors/cds.php
