Yageo AC0805KKX7R9BB105 is a pin-compatible, automotive-grade (AEC-Q200) alternative with a tighter ±10% tolerance.
TCC0805X7R105M500FT is a general-purpose 1uF 50V 0805 ceramic capacitor. Several pin-compatible alternatives with improved tolerance or higher voltage ratings are available from major manufacturers.
Most alternatives are upgrades in tolerance or voltage.
All suggested alternatives are in the same 0805 package.
Direct replacement for TCC0805X7R105M500FT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use a 1uF, 50V (or higher), X7R, 0805 capacitor with ±10% tolerance, such as parts from Murata, Yageo, or Samsung.
The primary risk is minimal, as most alternatives offer tighter tolerance (±10% vs ±20%), which is a performance improvement.
