FH (Guangdong Fenghua Advanced Tech)
Shares package and capacitance but has a lower voltage rating (16V) and wider tolerance (±10%).
Finding a replacement for the FH 0402B104J250NT, a 100nF 25V 5% 0402 capacitor, requires careful attention to voltage and tolerance. While some parts match in capacitance and package, they may have lower ratings.
Candidates have lower voltage and wider tolerance.
Package size 0402 is a standard match.
No direct drop-in replacement was identified. All candidates with matching capacitance had significant downgrades in voltage or tolerance.
Search for a 100nF, 25V (or higher), ±5% (or tighter), X7R, 0402 capacitor from another manufacturer.
Using a part with a lower voltage rating, which could lead to component failure if the circuit voltage exceeds the new, lower limit.
