UNI-ROYAL
A 1MΩ, 1W resistor in a 2512 package, but with a wider tolerance (±5%) and lacking automotive qualification.
Yageo's AC2512FK-071ML is a 1MΩ, 1W, ±1% tolerance automotive-grade (AEC-Q200) chip resistor in a 2512 package, ideal for high-reliability applications.
Tolerance downgrade from ±1% to ±5% can impact circuit precision.
Lack of AEC-Q200 qualification makes substitutes unsuitable for automotive applications.
No direct, drop-in replacements have been verified. Alternatives exist but have wider tolerance and lack automotive qualification, requiring careful review.
Search for other AEC-Q200 qualified, 1MΩ, 1W, ±1% resistors in a 2512 package from manufacturers like Vishay, KOA, or Panasonic.
The primary risk is using a non-AEC-Q200 qualified part with a wider tolerance (±5%) in an application designed for a ±1% automotive-grade component.
