Is there a pin-compatible replacement for 0603WAF1604T5E?

Yes, several 0603 package resistors are pin-compatible. However, available alternatives have different key electrical parameters like resistance or tolerance, so they are not direct functional replacements without design validation.

What risks should I check before replacing 0603WAF1604T5E?

The main risks are electrical. Check if your circuit can function correctly with a wider resistance tolerance (up to ±5%) or a different nominal resistance (e.g., 1.5MΩ instead of 1.6MΩ). This is critical for precision circuits.
