Is there a pin-compatible replacement for TD03G2492BT?

Yes, several parts like the Yageo RT series are available in the same 0603 package. However, they are parametric alternatives, not exact electrical matches. The closest is RT0603BRD0725K5L, which has a slightly different resistance value that must be verified for your application.

What risks should I check before replacing TD03G2492BT?

The main risk is the difference in resistance. The target is 24.9kΩ, while alternatives are typically 25.5kΩ or 23.7kΩ. This can affect circuit accuracy. Also, ensure any replacement is a thin-film type with the same low tolerance (±0.1%) and TCR (±25ppm/°C) to maintain precision.
