Is there a pin-compatible replacement for CC0603KRX7R9BB393?

No verified pin-compatible replacement is confirmed. The kept parts share 0603 2-pin form but need FAE review.

What risks should I check before replacing CC0603KRX7R9BB393?

Check capacitance tolerance, DC bias, voltage margin, temperature range, and whether the circuit accepts 33 nF or 47 nF.

CC0603KRX7R9BB393 is a 39 nF 50 V X7R 0603 MLCC. Nearby 33 nF or 47 nF parts need capacitance review.

No direct verified replacement is shown in the provided data.

Check same-series 39 nF first; otherwise review 33 nF or 47 nF as relaxed options.

Capacitance shift changes filter, timing, or decoupling behavior.

47 nF 0603 X7R part may fit mechanically but changes capacitance.
