Needs validationmedium risk
A 1kΩ 0.1% 0402 resistor from Viking Tech with a higher TCR (±25 ppm/°C) than the target.
Best Alternatives to RT0402BRB071KL
Explore alternatives for the Yageo RT0402BRB071KL, a high-precision 1kΩ 0.1% 10ppm/°C 0402 resistor. While pin-compatible options exist, they typically have a higher temperature coefficient, requiring careful evaluation for your application.
AI replacement insight
Electrical riskmedium
Higher TCR (25-50ppm/°C vs 10ppm/°C) can impact precision in sensitive analog circuits.
Package risklow
All candidates match the 0402 package, ensuring form and fit compatibility.
Can it be replaced directly?
No direct drop-in replacement with an identical 10ppm/°C TCR was found. All candidates are parametric alternatives with a higher TCR, requiring engineering validation.
Best replacement path
Use a candidate with 25ppm/°C TCR like AT0402BRD071KL (AEC-Q200) or TC0225B1001TCC, after verifying temperature stability requirements.
Main risk
Increased resistance drift with temperature changes due to the higher Temperature Coefficient of Resistance (TCR) of the alternatives.
