    Electronics supplier or co-design partner? 7 situations that show the difference

    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

    Catalog supplier

    Found only at the PO. Find, validate, re-qualify — production stops.

    Co-design partner

    Alerted months ahead. Validated alternatives ready — production never stops.

    2 · Design change mid-project

    Catalog supplier

    Redesign, re-quote, re-prototype, re-qualify. Months lost.

    Co-design partner

    Impact checked in days. Updated prototypes within the timeline.

    3 · Thermal or EMC issue at certification

    Catalog supplier

    Back to design: find the cause, fix, rebuild, retest. Weeks of delay.

    Co-design partner

    Risks found at the schematic review. Pass certification the first time.

    4 · New product variant needed

    Catalog supplier

    Start from zero: new spec, supplier, qualification. 12–18 months.

    Co-design partner

    Shares the platform. Qualified in much less time.

    5 · Field failures in a shipped batch

    Catalog supplier

    Traceability takes days or weeks — if records exist at all.

    Co-design partner

    Full traceability in hours. Root cause found the same day.

    6 · New regulation affects your product

    Catalog supplier

    Supplier doesn’t monitor new regulations — it’s your problem.

    Co-design partner

    Regulations monitored. Design updates before the deadline.

    7 · BOM costs more than it should

    Catalog supplier

    Built from a reference schematic — you pay for unused features.

    Co-design partner

    Designed for your application. Every component is needed.
