Is there a pin-compatible replacement for AR03BTCX2003?

While several resistors share the 0603 package, no direct pin-compatible replacement with identical 200kΩ resistance and 0.1% tolerance was found. Alternatives require parametric review.

What risks should I check before replacing AR03BTCX2003?

The main risks are changes in resistance value, tolerance, and temperature coefficient (TCR). Using a resistor with a different value or wider tolerance can affect circuit accuracy and performance.

Electrical riskmedium

Resistance value mismatch requires circuit analysis.

Package risklow

Standard 0603 package is widely available.

Can it be replaced directly?

No direct, drop-in replacement for AR03BTCX2003 has been identified. All suitable candidates require engineering review due to differences in resistance value.

Best replacement path

Find a thin-film 0603 resistor with 0.1% tolerance and ≤25ppm/°C TCR. The closest options may have slightly different resistance values and require circuit validation.

Main risk

The primary risk is a shift in circuit behavior due to using a resistor with a different resistance value, even if other precision parameters match.

Recommended alternatives

A precision thin-film resistor with matching tolerance and TCR, but a lower resistance value of 182kΩ.
