Catch single-source risk before it hits procurement.
Component selection drives BOM cost more than most engineers realize (Protolabs). A single-source component locked in at design review becomes a production delay six months later. Search 105,000+ suppliers by part number or brand during design — then let our deep research system hunt for more alternatives while you finish the BOM.
How 3E Helps
Design-phase visibility
Don’t wait until procurement to discover a part is hard to source. Verify supplier availability and surface alternatives during design — when changing the BOM still costs nothing.
Beyond Mouser and Digi-Key
Catalog distributors cover standard parts. 3E indexes 105,000+ companies including specialty manufacturers, brokers, and suppliers that don’t list on authorized channels.
Surface alternatives in the background
Our deep research system runs multi-round investigations to verify additional suppliers for the parts on your BOM — turning a single-source dependency into a shortlist before procurement ever sees the file.
Electrical and mechanical in one place
Electronic, mechanical, industrial, and specialty components — ICs, passives, connectors, enclosures, fasteners, sensors, and more. One search, every category.
Example
Design review flags a single-source sensor
During design review, you realize a key pressure sensor has only one known supplier — and the lead time is 22 weeks. Search the part number on 3E: three alternative sources appear immediately, including one authorized distributor with stock. Subscribe to unlock contacts across the whole BOM and leave the searches running. Two weeks later, our deep research system surfaces a fourth supplier offering a drop-in equivalent at 40% lower unit cost.
Frequently Asked Questions
How does 3E help during the design phase?
Engineers typically search distributor sites during design to check availability and pricing. 3E adds 105,000+ companies to that search — manufacturers, brokers, and specialty suppliers that catalog distributors miss. The result is early visibility into sourcing risk and alternatives, before the BOM is handed off to procurement.
Do you cover mechanical and electrical components?
Yes. The 3E network 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 the network — or our deep research system will find it.
Can I search for alternative or equivalent parts?
Search by part number to see every company that carries it. Search by brand to find distributors and manufacturers for a product line. The AI deep research system then investigates and verifies suppliers carrying compatible or equivalent components — so your shortlist grows without manual work.
Why should engineers source components during the design phase?
According to Protolabs, component selection drives BOM cost more than most engineers realize — locking in a single-source component early can create supply chain bottlenecks later. Engineers typically evaluate 3-5 suppliers per component. 3E surfaces alternatives across 105,000+ companies covering electronic, mechanical, and specialty parts, so you can design with sourcing flexibility from day one — and the standing search keeps finding new sources long after the design freezes.
