Often times there is the proprietary issue. Component manufacturers make
components for various systems for various manufacturers that are not
available to techs and engineers unless you work for the proprietary
manufacturing company. If you can find the specs of these components then
you can find a close cross reference otherwise you are at their mercy. A .65
component can cost you $75 + dollars. I speak from many years of experience
working with specialzed equipment.
