Maybe it has not been an issue. If the part is replaced with the same part number, revision level should not make a difference to a certifying authority. Especially so if Foxboro did not change the specifications according to the PSS sheet. Typically, Foxboro issued a new part number if the functionality and/or specifications changed.

Riccardi Sent: Monday, March 16, 2015 10:40 AM To: foxboro@xxxxxxxxxxxxx Subject: [foxboro] "Like for Like" kind FBM100 series REV-0L Folks, We recently had an FBM01 REV-0L fail and replaced it with a REV-0P version. In the Nuclear, Pharma, and I am sure other industries that require validation, the documentation required to support replacement parts of a "Like for Like" kind is simpler. I cannot find any reference in the GCS web site that would point me to documentation for the various hardware revision levels that would support this "Like for Like" kind. Does one exist? What do other Nuclear, Pharma, and other industries that require validation do in this case? Thanks Joseph M.
