Is there a pin-compatible replacement for CRCW20101M00FKEF?

Yes, several resistors like Yageo RC2010FK-071ML are pin-compatible in a 2010 package. However, they have lower voltage ratings and lack AEC-Q200 qualification, so they are not drop-in replacements for all applications.

What risks should I check before replacing CRCW20101M00FKEF?

The main risks are electrical and qualification-related. Check that your circuit's maximum voltage is safely below the substitute's rating (often 200V). Also, verify if your application requires the AEC-Q200 automotive-grade qualification that the original part has.

Find substitutes for the Vishay CRCW20101M00FKEF, a 1MΩ 1% 0.75W 2010 chip resistor. Key considerations for replacement include matching its 400V rating and AEC-Q200 qualification.

AI replacement insight

Electrical riskhigh

Most alternatives have a 200V rating, half of the target's 400V, posing a high risk of failure if the application voltage is high.

Package risklow

Many alternatives share the same 2010 package, ensuring physical compatibility on the PCB.

Sourcing riskmedium

The target's AEC-Q200 qualification may be difficult to match with readily available commercial-grade parts.

Can it be replaced directly?

No direct, fully-equivalent replacement has been identified from the candidates. All alternatives require compromises on voltage rating or automotive qualification.

Best replacement path

For critical applications, seek another AEC-Q200 qualified 2010 resistor with a ≥400V rating. For general-purpose use, several pin-compatible parts exist but with lower voltage ratings.

Main risk

The primary risk is electrical overstress from using a substitute with a lower voltage rating (e.g., 200V vs. the target's 400V).

Recommended alternatives

Pin-compatible 1MΩ 1% resistor, but with a lower voltage rating and no automotive qualification.

Questions & answers

The best alternative depends on your application. If AEC-Q200 and a 400V rating are mandatory, you must find a part with matching specifications. If not, parts like Yageo's RC2010FK-071ML are physically compatible but have a lower 200V rating.
