Is there a pin-compatible replacement for R06B1B221KN0B0S0N0?

While several candidates share the same 'Disc' package, no direct pin-compatible replacement with identical key electrical parameters was identified. All reviewed options require engineering validation due to parametric differences.

What risks should I check before replacing R06B1B221KN0B0S0N0?

Primarily, verify your circuit's tolerance to capacitance changes. The available alternatives have higher capacitance (270pF or 470pF), which can alter circuit performance, especially in timing, filtering, or resonant applications.
