Is there a pin-compatible replacement for TD03G7501BT?

Yes, many 0603 resistors are pin-compatible in physical form. However, for a precision part like this, true electrical 'drop-in' compatibility requires matching the ±0.1% tolerance and ±25ppm/℃ TCR, which is critical.

What risks should I check before replacing TD03G7501BT?

The main risk is substituting with a lower-precision resistor. Using a part with higher tolerance (e.g., ±1%) or a worse Temperature Coefficient (TCR) can degrade circuit performance. Also, ensure the replacement is a thin film type for stability.
