Source components while you design

Component selection drives BOM cost more than most engineers realize. Search 105,000+ companies to find suppliers early — before procurement bottlenecks hit.

Design-Phase Discovery

Don't wait until procurement to find out a part is hard to source. Search during design to verify supplier availability and find alternatives before they're needed.

Beyond Authorized Distributors

Mouser and Digi-Key cover catalog parts. 3E covers 105,000+ companies — including specialty manufacturers, brokers, and suppliers that don't list on standard platforms.

AI Finds Alternatives

Our research system discovers additional suppliers for the parts on your BOM — giving you options before a single-source dependency becomes a production delay.

Mechanical + Electrical

Not just ICs and passives. Search for mechanical, industrial, and specialty components in the same place — connectors, enclosures, fasteners, and more.

BOM review reveals single-source risk

During design review, you realize a key sensor has only one known supplier. Search it on 3E — find 3 alternative sources immediately. Subscribe to unlock contact details across your entire BOM. Our AI keeps searching in the background.

How does 3E help during the design phase?

Engineers typically search for parts on distributor sites during design. 3E adds 105,000+ companies to that search — including manufacturers, brokers, and specialty suppliers. This helps identify sourcing risks and alternatives before handoff to procurement.

Do you cover mechanical and electrical components?

Yes. Our database spans electronic, mechanical, industrial, and specialty components. If it has a part number and someone supplies it, there's a good chance it's in our database — or our AI will find it.

Can I search for alternative or equivalent parts?

Search by part number to see all companies that carry it. Search by brand to find distributors and manufacturers for that product line. Our AI research system also discovers suppliers carrying compatible or equivalent components.
