Is there a pin-compatible replacement for RC-02K4023FT?

Yes, parts like FRC0402F4123TS are pin-compatible in terms of physical package (0402) and footprint. However, they are not electrically identical due to the difference in nominal resistance (412kΩ vs 402kΩ), so they are considered parametric alternatives, not direct drop-in replacements.

What risks should I check before replacing RC-02K4023FT?

The main risk is the change in resistance. A different value can affect the accuracy of voltage dividers, the frequency response of filters, or the gain of amplifier circuits. Always simulate or test the alternative in your specific application before committing to a replacement.

AI replacement insight

Electrical riskmedium

Resistance value differs, which may affect circuit timing, gain, or accuracy.

Package risklow

All suggested alternatives share the same 0402 package and pinout.

Can it be replaced directly?

No direct, identical replacement was found. The closest options have a nominal resistance of 412kΩ instead of 402kΩ.

Best replacement path

Use a 412kΩ 1% 0402 resistor like FRC0402F4123TS, but verify the ~2.5% resistance change is acceptable for the application.

Main risk

The primary risk is the deviation in nominal resistance, which could alter circuit behavior in precision applications like voltage dividers or filters.

Recommended alternatives

Parametric alternative with a 412kΩ resistance in the same 0402 package. TCR data is missing.
