Is there a pin-compatible replacement for 126RV0015?

Yes, the KNSCHA 189RV0037 is a pin-compatible upgrade. Other parts like XT470UF35V90RV0080 share the same package but have different capacitance and require engineering review before use.

What risks should I check before replacing 126RV0015?

Key risks include mismatched capacitance (e.g., 220uF or 470uF instead of 330uF) which can affect circuit stability, and lower ripple current ratings which can lead to premature failure. Always verify these parameters for your application.
