Yageo
Needs validationmedium risk
A close parametric match on TCR and tolerance, but resistance is 5% higher and it is not automotive qualified.
Best Alternatives to AT0603BRD07100KL
AT0603BRD07100KL is a 100kΩ, 0.1% tolerance, AEC-Q200 qualified thin film resistor for precision automotive applications. Finding a substitute requires careful matching of its electrical precision and automotive-grade reliability.
AI replacement insight
Electrical riskhigh
Most candidates have worse tolerance or TCR, impacting circuit precision.
Package risklow
All candidates share the same 0603 package, ensuring physical compatibility.
Sourcing riskhigh
Using a non-qualified part in a qualified design can violate compliance and reliability requirements.
Can it be replaced directly?
No direct, fully-qualified drop-in replacement was found among the candidates. All options involve compromises in automotive qualification, tolerance, or temperature stability.
Best replacement path
Search for another AEC-Q200 qualified resistor with 100kΩ resistance, ±0.1% tolerance, and ±25 ppm/°C TCR, such as from Yageo's 'AT' series or a competitor's automotive series.
Main risk
The primary risk is substituting a non-AEC-Q200 part into an automotive application, or using a part with wider tolerance/TCR in a precision circuit, leading to performance degradation or failure.
