AI replacement insight

Package risklow

All candidates share the same 0603 package, ensuring form/fit compatibility.

Electrical riskhigh

Alternatives may have different resistance values, wider tolerance, worse TCR, or different technology (thin vs. thick film).

Sourcing riskhigh

Substituting a non-AEC-Q200 part for an automotive-grade one is a major compliance and reliability risk.

Can it be replaced directly?

Yes, CRCW060349R9FKEA is a strong candidate for a direct, pin-to-pin replacement for CRCW060350R0FKEA, requiring minimal re-qualification.

Best replacement path

The best replacement is CRCW060349R9FKEA from the same manufacturer (Vishay). It is a near-perfect match with identical package, power, tolerance, TCR, and AEC-Q200 qualification.

Main risk

The main risk when substituting is using a non-AEC-Q200 qualified part in an automotive application, or accepting a part with wider tolerance (e.g., 5%) or different technology (thin film) without analyzing the circuit impact.

Recommended alternatives

A very close alternative from the same manufacturer with nearly identical resistance and all other key specs matching.
