Is there a pin-compatible replacement for 25121WF3002T4E?

Yes, alternatives in the same 2512 package exist, making them physically compatible. However, their electrical parameters like resistance and tolerance may differ, so they are not drop-in replacements and require review.

What risks should I check before replacing 25121WF3002T4E?

Before replacing, verify that your design can tolerate a different resistance value (e.g., 33kΩ vs 30kΩ) and potentially a wider tolerance (e.g., ±5% vs ±1%). Ensure the power rating is at least 1W.
