Finding a substitute for the ARG02BTC2493, a 249kΩ 0.1% precision resistor, involves balancing resistance value with performance. While no exact match exists, several parametric alternatives are available that require careful review.

AI replacement insight

Electrical riskmedium

Resistance change requires validation. Downgrades to tolerance/TCR will reduce circuit precision.

Package risklow

All suggested alternatives share the same 0402 package, ensuring physical compatibility.

Can it be replaced directly?

No exact drop-in replacement was found. The closest options are parametric alternatives that require engineering review of the resistance change.

Best replacement path

Prioritize thin film 0402 resistors like the Yageo RT series with ±0.1% tolerance and ±25ppm/°C TCR, accepting a minor resistance deviation.

Main risk

Change in resistance value, which could alter circuit timing, gain, or bias points.
