Is there a pin-compatible replacement for FRC0402F1742TS?

Yes, several 0402 chip resistors are pin-compatible in form factor. However, no exact parametric match was found. Alternatives like RC0402FR-0718KL have slightly different resistance values that require engineering review.

What risks should I check before replacing FRC0402F1742TS?

The main risk is the change in resistance value. The target is 17.4kΩ, while alternatives are around 17.8kΩ to 18kΩ. Ensure your circuit's performance is not adversely affected by this change. Also, verify the temperature coefficient (TCR) if not specified.

AI replacement insight

Electrical riskmedium

Resistance value differs from target; circuit tolerance must be verified.

Package risklow

Alternatives share the standard 0402 package.

Sourcing risklow

Alternatives are widely available from major manufacturers.

Can it be replaced directly?

No direct, drop-in replacement with the exact 17.4kΩ resistance was identified. The closest options are parametric alternatives with slightly different resistance values.

Best replacement path

Use a parametric alternative like Yageo's RC0402FR-0718KL, which has a slightly higher resistance of 18kΩ.

Main risk

The primary risk is the deviation in resistance from the original 17.4kΩ, which could affect circuit timing, biasing, or feedback loops.

Recommended alternatives

A 0402 chip resistor with the same package, power, and tolerance, but with a slightly higher resistance of 18kΩ.
