AI replacement insight
Electrical risklow
Low for thick-film to thick-film swaps. Medium if changing to thin film.
Package risklow
All candidates share the same 0402 package footprint.
Sourcing risklow
Multiple vendors offer compatible parts, improving availability.
Can it be replaced directly?
Direct replacement for CR-02FL6--100K should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Upgrade to a higher power part like Yageo RC0402FR-7W100KL for increased robustness, or select a direct pin-to-pin match like VO SCR0402F100K.
Main risk
The main risk is overlooking secondary parameters like TCR or pulse withstanding capability, especially when switching between thick and thin film technologies.
