Is there a pin-compatible replacement for RS-03K15R0FT?

Several candidates share the same 0603 package, making them physically compatible (form and fit). However, due to differences in electrical parameters like tolerance or resistance, they are not direct pin-to-pin functional replacements without engineering validation.

What risks should I check before replacing RS-03K15R0FT?

The main risks are electrical. Using a part with wider tolerance (e.g., ±5% vs ±1%) can affect circuit precision. Using a part with a different nominal resistance (e.g., 16Ω vs 15Ω) will alter circuit behavior. Always verify these parameters against your design requirements.
