Yageo
Excellent substitute with identical package, resistance, tolerance, power, and TCR.
Find pin-compatible substitutes and functional alternatives for the RS-03K2552FT, a 25.5kΩ 1% 0.1W 0603 thick film resistor. Review key parameter differences before selection.
All suggested alternatives are in the same 0603 package, ensuring physical compatibility.
Some candidates have different resistance or technology. These require engineering review.
Yes, RC0603FR-0725K5L from Yageo is a potential pin-to-pin replacement, offering the same 25.5kΩ resistance, ±1% tolerance, 0.1W power, and 0603 package.
RC0603FR-0725K5L is a strong candidate for a direct replacement, matching all key electrical and physical parameters.
The main risk is using a substitute with a different resistance value, which requires circuit analysis to ensure performance is not compromised.
