FOJAN
Pin-compatible substitute with same package and electricals, but with a tighter tolerance.
Find substitutes for the CCTC TCC0402X7R103M500AT, a 10nF 50V 0402 ceramic capacitor. Alternatives include pin-compatible upgrades and functional alternates in different packages.
All candidates match or exceed key electrical specs like voltage and have tighter tolerance.
Most candidates are not in a 0402 package, requiring a PCB layout change.
Yes, FCC0402B103K500AT is a potential pin-to-pin replacement with improved tolerance. Always verify land pattern compatibility.
The best path is FCC0402B103K500AT, which offers a tighter tolerance in the same 0402 package.
The main risk for most alternatives is a different package size, which requires a PCB redesign.
