AI replacement insight
Electrical riskhigh
±5% option downgrades precision.
Package riskmedium
2512 option needs PCB change.
Firmware risklow
Passive resistor; no firmware impact.
Sourcing risklow
Kept candidates are active catalog parts.
Can it be replaced directly?
No confirmed pin-compatible replacement is verified.
Best replacement path
For same footprint, review FRC1210J101 TS only if ±5% tolerance is acceptable; for redesign, consider 25121WF1000T4E.
Main risk
Tolerance, power derating, and package changes are the main risks.
