Genuine Siemens Spare Parts are original components manufactured or approved by Siemens as the Original Equipment Manufacturer (OEM), designed, tested, and built to the exact specifications of the equipment they serve. They function less as a catalogue of individual components and more as the lifecycle backbone that keeps automation, drive, and control systems running at their designed performance after commissioning.

Why genuine parts matter

• Quality, compatibility, and legal assurance. Official-channel parts guarantee quality and reliability, are validated for the specific device, and carry full manufacturer warranty and technical support. Purchasing through Siemens also protects against counterfeit or non-compliant components that may carry similar markings but lack traceability.

• Long-term availability and global logistics. Siemens normally retains spare parts for 10 years after a product is discontinued from active marketing, and in some service arrangements availability can extend further. Spare parts can be ordered 24/7—including weekends and holidays—through emergency logistics, with delivery options ranging from standard shipping to express courier for plant downtimes.

• Exchange and return options. For many products, Siemens offers an exchange model: the replacement part is supplied at a lower exchange price, and the defective unit can be returned for credit, provided it is repairable and the return criteria are met.

The portfolio and how to identify the right part

Genuine spare parts cover Siemens’ core automation and drive families—SIMATIC controllers and I/O, SINAMICS converters, SINUMERIK CNC systems, SIMOTICS motors, and SENTRON/SITOP power and protection components. To find the correct part, Spares on Web allows users to enter an article number and serial number and view the matching spare parts for that specific device; spare-part kits are also available for items such as SINAMICS G120 Control Units.

In short, Siemens' genuine spare parts proposition is about sustaining asset availability across the full lifecycle—through OEM-validated quality, predictable long-term supply, and digital identification tools—rather than simply selling replacement hardware.
