Obsolescence Solutions

Electronic component obsolescence presents a growing challenge across many industries, particularly within aerospace, defence, rail, medical and industrial applications where equipment lifecycles often exceed the availability of original components.



Charcroft supports customers throughout the product lifecycle, helping to identify replacement solutions, source hard-to-find components and maintain continuity of supply for legacy designs. Through our approved manufacturers, specialist sourcing partners and extensive industry experience, we help minimise the risks associated with end-of-life (EOL) components and supply chain disruption.


Whether you're managing an ageing product platform, supporting long-life equipment or seeking alternatives to discontinued components, our engineering and procurement teams can help identify the most appropriate solution.
