Is there a pin-compatible replacement for RT0805BRD0747RL?

Yes, many 0805 chip resistors are pin-compatible in form factor. However, for a precision part like the RT0805BRD0747RL, you must match key electricals: 47 Ohm resistance, ±0.1% tolerance, and 25 ppm/°C TCR. A simple package match is not enough.

What risks should I check before replacing RT0805BRD0747RL?

The main risks are changes in resistance, tolerance, and temperature coefficient (TCR). The target is a high-precision part (0.1%, 25 ppm/°C). Using a substitute with a different resistance value or a lower-grade part (e.g., 1% tolerance, 100 ppm/°C TCR) can affect circuit accuracy and stability.
