Replacing a discontinued model
A discontinued model does not force a redesign if mounting, output and accuracy class still match.
When a model is discontinued, the question is not what is new but what still fits.
Start from the constraints
List the mounting thread, the output signal and the accuracy class of the existing unit. These three usually decide whether a drop-in replacement exists.
Use the replacement note
Each discontinued model page lists the recommended replacement path. Follow it before considering a bracket change.
When a change is unavoidable
A thread adapter is usually cheaper than a reweld. An output change may only need a control-input reconfiguration.
Document the swap
Record the old code, the new code and the installation date, so the next replacement starts from that record.
