Is there a pin-compatible replacement for FRL1210JR300TS?

Yes, parts like FRL1210FR300TS and 1210W2F300LT5E match the 1210 package, 0.3Ω resistance, and 0.5W power rating, making them pin-compatible.

What risks should I check before replacing FRL1210JR300TS?

Ensure the replacement has the same resistance (0.3Ω), power rating (≥0.5W), and 1210 package. While tighter tolerance (e.g., ±1%) is usually safe, also check the temperature coefficient (TCR) if your application is temperature-sensitive.
