Replacement paths, side by side

The decisive attribute in this vertical is software and runtime compatibility, not electrical specs. Read the compatibility column before the price column.

Route	What	Price band	Availability	Compatibility — the dealbreakers
Official successor	SIMATIC Unified Comfort Panel (MTP series) Siemens	€3,134–3,375 across 2 EU distributors RS, 2026-09-04	In stock at RS (8 pcs)	Runtime changes from WinCC Advanced/Comfort to WinCC Unified. Existing TP1200 Comfort projects do not load unchanged; scripting moves from VBS to JavaScript. Why this matters ⌄
Caveat: The forum thread comparing TP1200 Comfort with MTP1200 Unified is explicit that the migration, not the hardware, is the decision. discussed on SPS-Forum →
Compatible third party	INSEVIS panel PC INSEVIS	Quoted on request; no public list price.	Direct from vendor	Different manufacturer, different engineering toolchain - the panel project is rebuilt, not converted. Named in the 74-reply Comfort Panel discontinuation thread as a working cross-vendor route. Why this matters ⌄
Caveat: Cross-vendor here is a rebuild project, not a swap. discussed on SPS-Forum →
Compatible third party	ADM Smart Panel ADM	Quoted on request; no public list price.	Direct from vendor	Requires runtime and licence conversion. Raised in the 'Replacement for Comfort Panels' thread - note that mention was a vendor post, so treat the compatibility claims as vendor-stated, not community-verified. Why this matters ⌄
Caveat: Source is a vendor advertisement in the forum's ad subforum. discussed on SPS-Forum →
Used / refurbished	Used / refurbished Comfort Panels Broker market	Not established in research	Broker and refurbisher stock, thinning as the guarantee window runs down	Identical hardware - the existing WinCC project loads unchanged. This is the only path with zero engineering effort. Why this matters ⌄
Caveat: Buys time to 2033 at most; the migration decision returns.

Where the research did not establish a figure, this page says so rather than estimating one. A number you cannot defend is worse than no number.
