AI replacement insight
Package risklow
Multiple candidates with identical 2512 packages are available.
Electrical riskmedium
While primary specs match, TCR is unknown. Parametric alternatives have different resistance or tolerance, requiring circuit validation.
Sourcing risklow
This is a common resistor value and package, with alternatives available from major manufacturers like Yageo and UNI-ROYAL.
Can it be replaced directly?
Direct replacement for FRC2512F2201TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
The Yageo AC2512FK-072K2L is the strongest candidate, offering identical core specs and an upgrade to AEC-Q200 automotive qualification.
Main risk
The primary risk is mismatch in secondary parameters like Temperature Coefficient (TCR), which is unspecified for the target part.
