What changes in your project when your electronics partner co-designs — not just builds to your specification.
On a normal day, both look the same. The difference appears when something changes: a component disappears, a regulation arrives, a certification fails. These are the 7 situations where a catalog supplier stops and a co-design partner continues.
1 · Component reaches end-of-life
Found only at the PO. Find, validate, re-qualify — production stops.
Alerted months ahead. Validated alternatives ready — production never stops.
2 · Design change mid-project
Redesign, re-quote, re-prototype, re-qualify. Months lost.
Impact checked in days. Updated prototypes within the timeline.
3 · Thermal or EMC issue at certification
Back to design: find the cause, fix, rebuild, retest. Weeks of delay.
Risks found at the schematic review. Pass certification the first time.
4 · New product variant needed
Start from zero: new spec, supplier, qualification. 12–18 months.
Shares the platform. Qualified in much less time.
5 · Field failures in a shipped batch
Traceability takes days or weeks — if records exist at all.
Full traceability in hours. Root cause found the same day.
6 · New regulation affects your product
Supplier doesn’t monitor new regulations — it’s your problem.
Regulations monitored. Design updates before the deadline.
7 · BOM costs more than it should
Built from a reference schematic — you pay for unused features.
Designed for your application. Every component is needed.
