FH (Guangdong Fenghua Advanced Tech)
Parametric alternative with same package and power, but 7.0% lower resistance.
Finding a substitute for the RS-03K4872FT, a 48.7kΩ 1% 0603 resistor, requires careful consideration as no direct drop-in replacements exist. Alternatives are available but have different resistance values that need engineering review.
Resistance mismatch requires circuit analysis to ensure performance is not negatively affected.
All suggested alternatives use the same 0603 package, ensuring physical compatibility.
No direct, drop-in replacement with the exact 48.7kΩ resistance value was found. All suitable alternatives require parametric relaxation and engineering review.
Evaluate candidates with the closest resistance values, such as RS-03K4992FT (+2.5%) or ARG03BTC4702 (-3.5%), for your specific application's tolerance to this deviation.
The primary risk is the deviation in resistance, which can impact circuit timing, gain, filtering, or sensor accuracy.
