Siemens’ products and<br>solutions constitute one element of such a concept. Customers are responsible<br>for preventing unauthorized access to their plants, systems, machines and<br>networks. Such systems, machines and components should only be connected<br>to an enterprise network or the internet if and to the extent such a connection is<br>necessary and only when appropriate security measures (e.g. firewalls and/or<br>network segmentation) are in place. For additional information on industrial<br>cybersecurity measures that may be implemented, please visit<br>www.siemens.com/cybersecurity-industry. Siemens’ products and solutions<br>undergo continuous development to make them more secure. Siemens strongly<br>recommends that product updates are applied as soon as they are available<br>and that the latest product versions are used. Use of product versions that are<br>no longer supported, and failure to apply the latest updates may increase<br>customer’s exposure to cyber threats.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
