Series-level lifecycle status — in Siemens' own PM milestone vocabulary (PM400 phase-out announcement, PM410 type discontinuation, PM490 product cancellation, PM500 end of lifecycle) — published milestone dates, and the OEM's recommended migration path for legacy Siemens automation: SIMATIC S5, S7-200, S7-300, ET 200M/S, MASTERDRIVES, MICROMASTER, legacy SIMATIC Panels, and legacy engineering software (STEP 5, STEP 7 V5.x, WinCC flexible, ProTool).
Siemens publishes lifecycle milestones per family and per article number, and the S7-300 / ET 200M phase-out ladder runs years into the future (PM490 in 2033, PM500 in 2035). Knowing where a family sits on that ladder — spare-parts-only, cancelled, or fully out of lifecycle — is what maintenance and modernization planning for the installed S5/S7 base depends on.
Verification standard: official Siemens sources first (Siemens product and support pages, TIA Portal documentation, Siemens Industry Mall, Siemens news, migration guides and brochures). Milestone dates are reproduced exactly as published and left blank where Siemens published none — no dates, part numbers, or successors are inferred. Records that rest on a distributor/secondary source because Siemens' own pages do not publish the fact in a readable form are tagged [distributor-sourced] and are lower-confidence.
| Product Family | Catalog/Series | Lifecycle Status | Discontinuation or milestone date | Recommended Replacement / Migration Path |
|---|---|---|---|---|
| SIMATIC S5 compact controllers | S5-90U, S5-95U, S5-100U, S5-101U (6ES5) | End of lifecycle — product life cycle ended; spare parts no longer available, repairs no longer possible (Siemens) | September 30, 2020 (Siemens UK article, published October 2020) | SIMATIC S7 — Siemens launched S7 in 1994 as the successor generation to S5; no model-level successor mapping published in the source |
| SIMATIC S7-200 CPUs | CPU 221 / 222 / 224 / 224XP / 226 (6ES7 21x) | Phase-out announced — "declared phased-out products" (Siemens S7-1200 Transition Manual) | Effective October 1, 2013; available as new components for one further year, until October 1, 2014, then as spare parts for an additional 9 years | SIMATIC S7-1200, engineered with STEP 7 Basic (TIA Portal) |
| SIMATIC S7-300 CPUs | CPU 312–319 incl. compact and fail-safe variants (6ES7 31x) | PM410 — type discontinuation (spare parts only) [distributor-sourced] | PM400 phase-out announced October 1, 2023; PM410 type discontinuation October 1, 2025; PM490 product cancellation October 1, 2033; PM500 end of lifecycle October 1, 2035 [distributor-sourced — Critical Spare Parts milestone table; EU Automation corroborates the PM410 date] | SIMATIC S7-1500 (main successor); S7-1200 for smaller installations (per EU Automation) |
| SIMATIC ET 200M distributed I/O | IM 153 interface modules and S7-300 signal modules for ET 200M (6ES7 153 / 6ES7 3xx) | PM410 — type discontinuation; components now only available as spare parts (Siemens Energy migration document) | PM400 phase-out announced October 1, 2023; PM410 type discontinuation October 1, 2025; PM490 product cancellation October 1, 2033; PM500 end of lifecycle October 1, 2035 | SIMATIC ET 200SP HA (successor named for PCS 7 upgrade projects in the Siemens Energy migration document) |
| MICROMASTER 440 | 6SE6440 | Replaced by the SINAMICS family per Siemens ("We have therefore decided to replace our MICROMASTER drives by converters from the current SINAMICS drive family"); no PM milestone dates published in the source | — (none published) | SINAMICS G120C or SINAMICS G120 (modular) (Siemens brochure mapping, by voltage variant) |

Facts compiled from public OEM lifecycle sources; not affiliated with or endorsed by Siemens. Trademarks belong to their owners. This is a migration-planning reference, not engineering sign-off. Siemens issues lifecycle milestones per article number, so family-level records must not be read as per-article dates — verify production-critical selections against Siemens' Product Lifecycle Management data for the exact order number before acting.
