Is there a pin-compatible replacement for FRC0603F2261TS?

Yes, several 0603 package resistors are pin-compatible. FRC0603F2211TS and RC0603FR-072K21L are excellent candidates with nearly identical specs, differing only slightly in resistance value. Always verify the resistance change is within your circuit's design margins.

What risks should I check before replacing FRC0603F2261TS?

The main risk is the change in resistance value; ensure your circuit tolerates the new value. For candidates with different technology (Thin Film vs. Thick Film), also verify pulse/surge withstanding capability, as it can differ.

AI replacement insight

Electrical riskmedium

Resistance values differ by up to 7.5%. Technology change to Thin Film affects pulse handling.

Package risklow

All candidates share the same 0603 package, ensuring form-fit compatibility.

Sourcing risklow

Multiple alternatives are available from different manufacturers like Yageo and FOJAN.

Can it be replaced directly?

No exact direct replacement with 2.26kΩ resistance was found in this batch. However, FRC0603F2211TS is a very close functional alternative from the same manufacturer.

Best replacement path

Use a thick film resistor with a close resistance value, such as FRC0603F2211TS (2.21kΩ) or RC0603FR-072K21L (2.21kΩ).

Main risk

Slight deviation in resistance value is the primary risk. A secondary risk involves changing from thick film to thin film technology, which affects precision and pulse handling.

Recommended alternatives

Strong alternative from the same manufacturer with a slightly lower resistance of 2.21kΩ.
