(Component Obsolescence Group) Deutschland e.V. The company's aim is to actively work on the establishment of guidelines and measures to prevent the consequences of components being unavailable for products. Moreover, within the scope of ongoing research and development, Würth Elektronik eiSos wishes to avoid this scenario for its own components.

As the largest European manufacturer of passive components it is one of the company's main aims to ensure component availability. This is also reflected in the company strategy, which guarantees all products in the catalogue to be ex stock.

The product life cycles of high-tech components and finished products have opened up more and more in the last decades. Modern components are at times superseded after only 6 months by replacements that are not always compatible.

Nevertheless, in the automotive industry, in space, military, railway, power generation and automation technologies, and in many other sectors, it is necessary that products can be supplied over many years with as little change as possible. When components of a product or system are no longer available, the term obsolescence is used. At the industry association COG (Component Obsolescence Group) Deutschland e.V. many operators work together on equal terms on the topic of obsolescence management.

The COG serves also as an information platform so that participants can exchange information. It also creates an awareness of the growing problem, leading to the advancement of proactive approaches. By following an adequate obsolescence strategy, the possible effects of a product discontinuation are kept to a minimum.
