Is there a pin-compatible replacement for WR04X4702FTL?

Yes, several 0402 package resistors are pin-compatible. Yageo RT0402BRD0747KL is a strong match, while others from FOJAN are options if a slight resistance change is acceptable.

What risks should I check before replacing WR04X4702FTL?

The primary risk is a mismatch in resistance. Verify that your circuit can tolerate any deviation from the original 47kΩ value. Also, consider technology differences (thin vs. thick film) for pulse-handling needs.
