Is there a pin-compatible replacement for C3D5UF500V82CB0304?

Several parts share the same Radial package with 27.5mm lead pitch, making them form-fit compatible. However, their electrical parameters, especially capacitance, differ and must be verified for your application.

What risks should I check before replacing C3D5UF500V82CB0304?

The main risk is functional failure due to mismatched capacitance. Candidates have lower capacitance (e.g., 2uF or 3.3uF vs 5uF), which can affect circuit timing, filtering, or energy storage. Always verify performance in your specific application.
