Is there a pin-compatible replacement for FRC0402F18R0TS?

Yes, any 18Ω, 1%, 0.0625W (or higher) resistor in a 0402 package is pin-compatible. However, you must also verify the temperature coefficient and voltage rating for your application.

What risks should I check before replacing FRC0402F18R0TS?

Key risks include using a resistor with incorrect resistance, lower power or voltage ratings, or a higher temperature coefficient (TCR), which can affect circuit performance and reliability.

FRC0402F18R0TS Alternatives, Datasheet & Cross Reference | FOJAN

FRC0402F18R0TS is a general-purpose 18Ω 1% 0402 chip resistor. Finding a direct, drop-in replacement requires matching resistance, power, voltage, and package size.

AI replacement insight

Electrical riskhigh

Candidates have incorrect resistance or lack power/voltage safety margins.

Package risklow

All candidates share the same 0402 package.

Can it be replaced directly?

No direct drop-in replacement was found in the provided candidates. The closest option has double the resistance and requires significant design review.

Best replacement path

Search for a 0402 chip resistor with exactly 18Ω resistance, ±1% tolerance, and a power rating of 0.0625W or higher.

Main risk

The primary risk is functional failure due to incorrect resistance values in the proposed candidates.

Recommended alternatives

A 0402 resistor with double the resistance (36Ω) and same power/voltage ratings. Requires careful review before use.
