Is there a pin-compatible replacement for 0402WGF1543TCE?

Yes, several parts like Yageo's RC0402FR-07162KL and AC0402FR-07150KL share the same 0402 package and pinout. However, their resistance values differ, so they are parametric, not direct, replacements.

What risks should I check before replacing 0402WGF1543TCE?

The main risk is the change in resistance. Verify if your circuit can tolerate values like 150kΩ or 162kΩ instead of 154kΩ. For high-frequency or noise-sensitive applications, also compare the characteristics of thick film vs. thin film technology if considering an upgrade.
