What risks should I check before replacing FRC0603J115TS?

Key risks include: 1) Electrical Stress: Ensure the replacement's power and voltage ratings meet or exceed your design's requirements. 2) Parametric Sensitivity: If choosing a part with a different resistance, verify your circuit's tolerance to this change. 3) Temperature Performance: Check if the replacement's TCR is suitable for your application.

AI replacement insight

Electrical riskmedium

Candidates match but do not exceed target's power/voltage ratings, violating standard derating rules.

Package risklow

All viable candidates use the same 0603 package.

Sourcing risklow

Multiple manufacturers produce similar 1.1MΩ 0603 resistors.

Can it be replaced directly?

Direct replacement for FRC0603J115TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The most direct path is 0603WAF1104T5E, which matches resistance and package while upgrading tolerance and TCR.

Main risk

The primary risk is the lack of increased power and voltage rating margins in available alternatives, which may be insufficient for designs operating near the target part's limits.

Recommended alternatives

A 1.1MΩ 0603 resistor with tighter tolerance (±1%) and better TCR (±100ppm/°C), but requires review of power and voltage margins.
