Is there a pin-compatible replacement for 1206W4F5104T5E?

Yes, several parts share the 1206 package, but they have different electrical parameters. For example, FRC1206J515 TS has a ±5% tolerance instead of ±1%.

What risks should I check before replacing 1206W4F5104T5E?

Key risks include changes in resistance value or tolerance. A lower resistance (e.g., 4.7MΩ) or wider tolerance (±5%) can affect circuit timing, biasing, or accuracy. Always verify against your design's requirements.
