Is there a pin-compatible replacement for FRC0402F1133TS?

Yes, several candidates like FRC0402F1203TS and RT0402BRD07120KL share the same 0402 package and 2-pin layout, making them physically pin-compatible. However, their electrical parameters, especially resistance, differ and must be verified.

What risks should I check before replacing FRC0402F1133TS?

The main risk is the resistance difference; no candidate is exactly 113kΩ. You must verify your circuit can tolerate values like 120kΩ or 102kΩ. Also, check for technology differences (Thick vs. Thin Film) and tolerance downgrades (e.g., to ±5%).

AI replacement insight

Electrical risklow

Resistance value differs. Verify circuit tolerance. Some options have different technology (Thin Film).

Package risklow

All viable candidates share the same 0402 package, ensuring physical compatibility.

Sourcing riskhigh

Using a part with different resistance may not be acceptable. One option is a significant tolerance downgrade.

Can it be replaced directly?

There is no exact drop-in replacement in the provided list. All candidates have different resistance values. FRC0402F1203TS is the closest functional match.

Best replacement path

The best replacement path is FRC0402F1203TS, which is from the same manufacturer series and has identical core specifications, differing only in resistance (120kΩ vs 113kΩ).

Main risk

The primary risk is the resistance deviation. The closest options are 120kΩ (~6% high) or 102kΩ (~10% low). This must be validated against the circuit's sensitivity.

Recommended alternatives

Parametric alternative from the same series with a lower resistance of 102kΩ.
