FH (Guangdong Fenghua Advanced Tech)
Similar 100nF 0402 capacitor but with a lower 25V rating and tighter ±5% tolerance; requires circuit voltage verification.
0402B104K500NT is a 100nF, 50V, X7R ceramic capacitor in a 0402 package from FH. Finding a replacement requires matching these key parameters, especially the 50V voltage rating.
Using a part with a lower voltage rating (e.g., 25V or 10V) in a 50V circuit can lead to immediate or premature failure.
The 0402 package is standardized, so physical fit is not a primary concern.
No direct, drop-in replacements with identical or better voltage ratings were found in this review. Alternatives with lower voltage ratings exist but carry significant risk.
Find a 100nF, 0402, X7R capacitor with a voltage rating of 50V or higher from another manufacturer.
Component failure due to using a substitute with an insufficient voltage rating.
