AEC-Q200 qualified alternative with matching specs but a 4.8% higher resistance of 6.8kΩ.
Explore alternatives for the FRC0603F6491TS 6.49kΩ 1% 0603 resistor. While no direct drop-in replacements are listed, several parametric alternatives with similar packages and ratings are available for review.
Resistance value mismatch is the primary electrical risk.
All candidates share the same 0603 package, ensuring physical compatibility.
No direct, drop-in replacement with the exact 6.49kΩ resistance has been identified. All candidates require engineering review due to different resistance values.
The closest alternative is FRC0603F6341TS from the same manufacturer, with a 2.3% lower resistance. All other parameters match.
The primary risk is the deviation in resistance value, which can range from 2.3% to 9.1% across candidates. This may affect circuit performance, especially in precision applications.
