AI replacement insight
Electrical risklow
Exact-value candidates match key specs.
Package risklow
0603 and 2 terminals are listed.
Firmware risklow
Passive resistor; no firmware.
Sourcing riskmedium
Cross-vendor availability varies.
Can it be replaced directly?
RC0603FR-0740K2L and FRC0603F4022TS are the closest catalog matches, but final PDF review is still required.
Best replacement path
Prefer exact 40.2kΩ ±1% 0603 thick-film parts before relaxed 40kΩ or 39kΩ options.
Main risk
Equal 100mW power rating and unreviewed PDFs require derating and footprint confirmation.
