Parametric alternative with different resistance (2.49kΩ vs 2.4kΩ) and is not AEC-Q200 qualified.
Finding a substitute for the AT0603BRD072K4L, a 2.4kΩ 0.1% automotive resistor, requires careful review of resistance, TCR, and AEC-Q200 qualification.
Resistance and TCR mismatches require circuit validation.
All reviewed candidates share the same 0603 package.
Lack of automotive grade is a critical feature gap for intended applications.
No direct, drop-in replacement is identified. All candidates have parametric differences or lack automotive qualification.
Search for an AEC-Q200 qualified, thin film, 0603 resistor with 2.4kΩ resistance and ≤±25ppm/°C TCR.
The primary risk is using a non-automotive grade component in an application requiring AEC-Q200 reliability.
