FH (Guangdong Fenghua Advanced Tech)
Same manufacturer and series with matching specs but higher resistance (820kΩ).
Find and compare parametric alternatives for the RS-03K7683FT, a 768kΩ 0603 thick film resistor. This page analyzes substitutes with similar packages and ratings but different resistance values that require engineering review.
Resistance values differ by 2-10%. This requires circuit analysis but is often acceptable in non-critical applications.
All suggested alternatives use the same 0603 package, ensuring physical compatibility.
No direct, drop-in replacement with the exact 768kΩ resistance was found. All viable alternatives have slightly different resistance values.
Use a parametric alternative like 0603WAF7873T5E, which has a very close resistance value, after verifying its impact on your circuit.
The primary risk is the change in resistance, which could alter the timing, biasing, or feedback characteristics of your circuit.
