Supply Chain Alert: Siemens Announces Official Phase-out Date for SIMATIC S7-1200 G1 – What You Should Do Now

The industry’s most reliable workhorse is entering its final chapter. Siemens has officially announced the phase-out schedule for the SIMATIC S7-1200 First Generation (G1) series, with total production set to cease by November 2026.

While the new G2 series is on the horizon, the sudden announcement has triggered a "stock-up" trend across global markets. For many manufacturers using G1 in existing machine designs, the window to secure long-term spare parts and maintenance inventory is closing faster than expected.

According to the Siemens lifecycle management plan, the S7-1200 G1 series will move from "Active" to "Phase-out" status. This means:

• Escalating Prices: As production scales down, unit costs for the remaining stock typically rise.
• Extended Lead Times: Market reports already show delivery times stretching from weeks to months as large-scale integrators begin "panic-buying" to protect their existing projects.
• Transition to Spare Part Status: Post-November 2026, these units will only be available through limited spare-part channels, often at a premium price.

The phase-out impacts the entire first-generation lineup, including the most popular CPUs and modules:

• CPU 1211C, 1212C, 1214C, 1215C, and 1217C (e.g., 6ES7214-1AG40-0XB0, 6ES7215-1BG40-0XB0).
• SM Digital/Analog Modules (6ES7221, 6ES7222, 6ES7223, 6ES7231, 6ES7232, 6ES7234).
• Signal Boards and Communication Modules (SB 1221, CM 1241, CP 1243).

Engineers are faced with a dilemma: while the S7-1200 G2 offers superior performance, migrating an existing machine design requires updated TIA Portal versions, potential wiring changes, and extensive re-validation. To avoid the high cost of engineering redesigns, many companies are choosing to bulk-purchase G1 units now to cover their production and maintenance needs for the next 3 to 5 years.

How should your procurement team respond?

1. Inventory Audit: Identify how many G1 units are currently deployed in your facility and calculate your annual failure/replacement rate.
2. Safety Stocking: Secure at least 24 months of critical inventory before the lead times become unmanageable.
3. Migration Planning: Start evaluating the S7-1200 G2 for all new machine designs to ensure you aren't building "legacy" systems into your future products.

In this volatile market, having a reliable sourcing partner is essential. Shanghai Fradwell Industrial Automation has pre-emptively secured a robust inventory of the most critical S7-1200 G1 components to support our global partners during this transition.

• Immediate Stock: We currently hold inventory for high-demand models like the CPU 1214C and 1215C.
• Global Sourcing Power: If we don’t have it in our Shanghai warehouse, our network can track down the exact part number you need.
• Migration Advisory: Our engineering team can help you determine which G1 modules can be directly replaced by G2 or if a hardware redesign is necessary.
