Is there a pin-compatible replacement for CRCW040247K0FKED?

Yes, several 0402 resistors with 47kΩ resistance are available. The Panasonic ERJPA2F4702X is a strong candidate for a pin-compatible upgrade. Always verify datasheets for land pattern compatibility.

What risks should I check before replacing CRCW040247K0FKED?

Key risks include using a part with a lower power rating, wider resistance tolerance (>1%), or one that is not AEC-Q200 qualified if your application requires it. Also, check for technology differences (Thick vs. Thin Film).

CRCW040247K0FKED Alternatives, Datasheet & Cross Reference | Vishay

The Vishay CRCW040247K0FKED is a 47kΩ, 1% tolerance, 0.063W thick film chip resistor in an 0402 package, qualified to AEC-Q200 for automotive use. Finding a substitute requires matching these key parameters.

AI replacement insight

Electrical risklow

Low if power, resistance, and tolerance are matched or improved. High if downgraded.

Package risklow

Low for candidates with the same 0402 package.

Sourcing riskhigh

High if a substitute lacks the required AEC-Q200 qualification for the application.

Can it be replaced directly?

Yes, the Panasonic ERJPA2F4702X is a potential pin-compatible upgrade. Other candidates may have different power ratings, tolerances, or lack AEC-Q200 qualification and require careful review.

Best replacement path

The Panasonic ERJPA2F4702X is a strong upgrade, offering a higher power rating (0.25W) and anti-surge protection while matching all other key specifications.

Main risk

The main risk is using a substitute that lacks the target's AEC-Q200 qualification or has a wider tolerance (e.g., 5%), which could compromise reliability.

Recommended alternatives

Strong upgrade with higher power rating and anti-surge feature, matching all other key parameters including AEC-Q200.
