Is there a pin-compatible replacement for SCR0603F115K?

While no exact drop-in replacement with 115kΩ resistance is listed, several parts like RC0603FR-07113KL are available in the same 0603 package. These are form-fit compatible, but require engineering review due to slight resistance differences.

What risks should I check before replacing SCR0603F115K?

Key risks include the resistance deviation, which can affect circuit timing or gain, and the lack of increased power rating margin in the alternatives. Also, switching from thick film to thin film (RT series) can change noise performance.
