When a manufacturer discontinues a VFD or HMI series, they usually publish an official successor and a model cross-reference — but "successor" is not the same as "drop-in replacement." Each guide below summarizes the manufacturer's own migration path, the model mapping, and what to verify before you order.
Every guide here is built the same way: the manufacturer's official successor platform, an official model cross-reference table, the option/fieldbus changes that come with it, and the specific checks worth confirming before you commit — current rating, dimensions, communication, encoder feedback and more. None of these treat "successor" as an automatic one-to-one replacement — where the manufacturer doesn't guarantee interchangeability, we say so.
These six cover the migrations we're asked about most. If your discontinued model isn't listed, send us the type code or nameplate photo — we'll tell you the manufacturer's official successor path (if one exists) and what to verify before ordering, the same way we do for every guide above.
Tell us the brand, type code and application — within 48 hours you get an honest migration judgment. Official successor path, model fit, and anything we think you should verify before ordering.
