Is there a pin-compatible replacement for GRT155R61C105KE01D?

Yes, GRT155C81E105KE13D is a potential pin-compatible replacement. It shares the same 0402 package and pinout. However, its dielectric material (X6S) differs from the original's (X5R), which requires engineering validation.

What risks should I check before replacing GRT155R61C105KE01D?

Key risks include: 1) Application Mismatch: Using a non-AEC-Q200 part in an automotive circuit. 2) Electrical Mismatch: A different dielectric (like X6S vs. X5R) will change the capacitance over temperature. 3) Tolerance: A wider tolerance (e.g., ±20%) may impact circuit stability.
