Is there a pin-compatible replacement for FRC0603F1151TS?

Yes, several 0603 package resistors are pin-compatible. However, no exact 1.15kΩ 1% match was found. Alternatives have slightly different resistance (e.g., 1.1kΩ or 1.2kΩ) and require engineering review.

What risks should I check before replacing FRC0603F1151TS?

The main risk is the resistance deviation from 1.15kΩ. Verify if your circuit can tolerate a ~4% change. Also check for differences in technology (Thin vs. Thick Film) which can affect noise and stability.

Electrical riskmedium

Resistance differs by ~4%, requiring circuit analysis.

Package risklow

All viable candidates share the same 0603 package.

Sourcing risklow

Alternatives are from major manufacturers like Yageo.

Can it be replaced directly?

No direct, drop-in replacement with the exact 1.15kΩ resistance and 1% tolerance was identified. Review of parametric alternatives is required.

Best replacement path

Parametric alternatives with slightly different resistance values (1.1kΩ or 1.2kΩ) are the most viable path.

Main risk

The primary risk is the resistance value mismatch, which could affect circuit performance in precision applications.

Recommended alternatives

AEC-Q200 qualified 0603 resistor with slightly higher resistance (1.2kΩ) but otherwise matching parameters.
