Custom components service

From obsolete parts to bespoke designs, we deliver the components others can't.

When standard components are no longer available, don't quite meet your specifications, or create supply chain challenges, Farnell's Custom Components service provides a smarter alternative. We work with customers to identify, source, engineer and deliver bespoke component solutions tailored to specific technical, commercial and lifecycle requirements.

Whether you need a replacement for an obsolete part, a modified version of an existing component, or a fully custom-designed solution, our experienced team helps reduce redesign costs, minimise supply risk and accelerate time to market. Leveraging a global network of manufacturers and engineering partners, we can support a wide range of applications across industrial automation, test and measurement, power management, connectivity, electromechanical systems and more.

Our service is designed to solve complex sourcing and product development challenges. We help customers extend the life of existing equipment, improve product performance, optimise costs and secure long-term supply continuity. From concept through to production, we provide expert guidance, technical support and quality-focused solutions that align with your project objectives.
