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.
