Is there a pin-compatible replacement for ERA2AEB431X?

Yes, several 0402 resistors are pin-compatible. However, no direct drop-in with identical 430Ω resistance and 0.1% tolerance was found. Alternatives require engineering review.

What risks should I check before replacing ERA2AEB431X?

Verify if your circuit can accept a different resistance value. If using a lower-spec part, check for impacts from wider tolerance (e.g., ±1% vs ±0.1%), different technology (thick vs. thin film), and higher temperature coefficient (TCR).

ERA2AEB431X Alternatives, Datasheet & Cross Reference | PANASONIC

The Panasonic ERA2AEB431X is a high-precision, AEC-Q200 qualified thin film chip resistor in a 0402 package, offering 430Ω resistance with a tight ±0.1% tolerance.

AI replacement insight

Electrical riskhigh

High risk if using a general-purpose part in a precision circuit.

Package risklow

Standard 0402 package is widely available.

Can it be replaced directly?

No direct drop-in replacement with identical parameters has been found. Alternatives require careful review of resistance value or precision tolerance.

Best replacement path

The best path is to use another part from the same Panasonic ERA2A series, like ERA2AEB471X, if the application can tolerate a 470Ω resistance.

Main risk

Key risks include mismatched resistance values or significant downgrades in precision (tolerance, TCR) and technology (thin vs. thick film).

Recommended alternatives

AEC-Q200 qualified alternative from the same series with identical precision but 470Ω resistance.
