Obsolete Siemens Parts Sourcing

End-of-life Siemens models, sourced globally and tested before shipping.

Overview

Siemens retired the SIMATIC S7-200 platform in 2017 and phased out large parts of the S7-300 catalogue after the S7-1500 launch — yet S7-200 and S7-300 racks still control countless packaging machines, HVAC plants and production lines in China and worldwide. TGK Parts sources obsolete Siemens parts through a global surplus network of verified dealers, factory decommissioning stock and integrator inventories.

Send us the complete MPN (order number) or a nameplate photo. We reply within 12 hours with availability, condition grade, price and lead time — and every sourced unit is bench-tested before shipping.

FAQ

Is the Siemens S7-200 still available?

No — Siemens officially discontinued the S7-200 in 2017. We source S7-200 CPUs and modules from global surplus and decommissioned stock, tested before shipping.

Can you source S7-300 modules Siemens no longer lists?

Yes — S7-300 I/O, CPs and PS modules are a core sourcing line for us. Send the full order number (e.g. 6ES7 322-1HH01-0AA0) for a quote.

What is the difference between an obsolete part and a refurbished part?

Obsolete means the OEM no longer produces it; refurbished describes the condition. Our obsolete S7-300 stock is typically used-but-tested or refurbished to grade A standard.

Do you supply the MICROMASTER 440 BOP/AOP panel?

Yes — MM440 panels and complete drives are in regular sourcing rotation, with alternatives via SINAMICS G120 retrofit where needed.

How fast can a discontinued Siemens CPU ship?

In-stock units ship within 24-48 hours; sourced units typically close in 3-10 days with updates every 48 hours.
