Strong alternative with identical key parameters and a higher voltage rating (100V).
The Walsin 0603N150J500CT is a general-purpose 15pF, 50V, 5% tolerance MLCC in a 0603 package. Several alternatives exist, but careful review of tolerance and capacitance is required.
Low if parameters match; medium if tolerance is relaxed or capacitance differs.
Many 0603 package alternatives are available.
Direct replacement for 0603N150J500CT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
TCC0603COG150J101CT offers a direct parametric upgrade with a higher voltage rating.
The main risk is selecting a part with incorrect capacitance or wider tolerance, which can impact circuit performance.

Strong alternative with identical key parameters and a higher voltage rating (100V).
