Is there a pin-compatible replacement for MFR01SF100JA10?

MF2WS-10Ω±1% T is a potential pin-compatible upgrade. While both are axial resistors, their body dimensions may differ due to the higher power rating, so a physical fit check is necessary.

What risks should I check before replacing MFR01SF100JA10?

Key risks include: 1) Physical size differences, even for axial packages. 2) Worse tolerance (e.g., ±5% vs ±1%) on some alternatives. 3) Different resistor technology which can affect noise and stability.
