Package risklow
Low only for 0603 candidates.
Firmware risklow
Passive resistor; no firmware.
Sourcing risklow
Catalog matches are active.
Can it be replaced directly?
FRC0603F1802TS is the closest candidate, but PDF and power-margin checks are still required.
Best replacement path
Prefer same 0603, 18kΩ, ±1%, 0.1W, ±100ppm/°C parts before relaxed values or 0805 options.
Main risk
The main risks are footprint mismatch and insufficient power derating.
