Is there a pin-compatible replacement for GRM188C71A475KE11D?

Yes, GRM188C71C475KE21D is a pin-compatible replacement. It shares the same 0603 package, capacitance, tolerance, and X7S dielectric, making it a form, fit, and functional match with an improved voltage rating.

What risks should I check before replacing GRM188C71A475KE11D?

Before replacing, verify the dielectric material (X7S is specified for -55°C to +125°C), as alternatives like X5R or X6S have lower temperature ratings. Also, check the capacitance tolerance to ensure it meets your circuit's requirements.
