Grace, Thanks for your prompt response. Do this procedure have to be followed for every alternate part, e.g. a parts shortage of a +24Vdc, 0.15A fan would require us to have to go through CQC change process prior to being able to pick up a fan to the exact same procurement spec from a different vendor? Thanks and regards, Craig

Please let me know if I can be of any further assistance.

These parts are rated +24Vdc or less and the majority of them are supplied for limited power sources. We have been informed CQC will not accept this practice for products which are to be CCC certified. We do not understand what added safety this restriction brings provided the alternate parts are bought to the same spec. Enforcing this rule would have serious implications for us. Before we do it I would like to know: Have you experienced similar issues? If so, how did you manage to comply with it? Any information or advice would be gratefully received.
