Yageo
A strong pin-to-pin match with identical capacitance, voltage, tolerance, and 0402 package for RF applications.
RF15N0R8A500 is a 0.8pF, 50V, high-precision (±0.05pF) NP0 ceramic capacitor in an 0402 package, designed for RF and microwave applications. Finding a substitute requires matching these tight specifications.
Low if using a matched Hi-Q part like CQ0402ARNPO9BNR80; high otherwise.
Low, as 0402 is a standard SMT package.
Yes, CQ0402ARNPO9BNR80 is a direct replacement for RF15N0R8A500, matching all critical specifications.
The most reliable replacement path is to use Yageo's CQ0402ARNPO9BNR80, which is a direct pin-to-pin match.
The main risk is using a general-purpose capacitor or one with looser tolerance, which can degrade performance in sensitive RF circuits.
