AEC-Q100 Qualification for Automotive Components
2 resources tagged with "Aec Q100"
AEC-Q100 is the stress-test qualification standard for integrated circuits used in vehicles, defining temperature grades (Grade 0 at -40 to +150°C down to Grade 3 at -40 to +85°C) and a battery of reliability tests. It's the line between a chip that survives an engine bay and a consumer part that won't, which is why it shows up on 77GHz radar transceivers and CAN bus interface ICs sourced from China. The sourcing pitfall is a module built with non-qualified silicon while the datasheet implies automotive readiness — so you verify the grade on the actual part number, not the module brochure.
When AEC-Q100 is required, the trap is assuming the module inherits the qualification — it doesn't; only the qualified component does. We check the specific IC's AEC-Q100 grade against the temperature range your application needs.

FAQ
What do AEC-Q100 grades mean?
Grade 0 covers -40 to +150°C, Grade 1 -40 to +125°C, Grade 2 -40 to +105°C, and Grade 3 -40 to +85°C. Pick the grade that matches where the part lives in the vehicle.
How do I verify AEC-Q100 on a Chinese-sourced module?
Get the exact IC part number and confirm its grade from the manufacturer's qualification data — the module's marketing doesn't count. Substituting consumer-grade silicon into 'automotive' modules is a known shortcut.
