Is there a pin-compatible replacement for AR05BTS2202?

Yes, several 0805 resistors like Viking's ARG05BTC2202 and Yageo's RT0805BRE0722KL are pin-compatible in package. However, their electrical characteristics, especially TCR, differ and must be reviewed.

What risks should I check before replacing AR05BTS2202?

The main risk is performance degradation due to temperature changes. The target has a very stable TCR of ±5ppm/°C. Many alternatives have a higher TCR (e.g., ±25ppm/°C), which can cause resistance drift in your circuit.

AR05BTS2202 Alternatives, Datasheet & Cross Reference | Viking Tech

AR05BTS2202 is a 22kΩ, 0.1% precision thin-film resistor in an 0805 package. Finding a substitute requires matching its tight ±5ppm/°C temperature coefficient (TCR).

AI replacement insight

Electrical riskhigh

TCR mismatch is the primary risk, affecting circuit accuracy and stability over temperature.

Package risklow

Multiple 0805 package candidates are available, ensuring mechanical compatibility.

Can it be replaced directly?

No direct drop-in replacement has been identified. While some parts match package and resistance, they have a weaker Temperature Coefficient of Resistance (TCR), which is a critical parameter for this precision part.

Best replacement path

Search for 0805 thin-film resistors with 22kΩ, ±0.1% tolerance, and a TCR of ±5ppm/°C or better.

Main risk

Circuit instability or inaccuracy due to the substitute having a higher TCR than the original part.

Recommended alternatives

A pin-compatible alternative with matching resistance and tolerance, but a weaker temperature coefficient (TCR).
