Walsin Technology Corporation
A strong pin-to-pin match with identical resistance, tolerance, power rating, and 0402 package.
Find verified substitutes for the RTT022002FTH, a 20kΩ 1% 1/16W 0402 thick film resistor. Review pin-compatible and parametric alternatives from top manufacturers.
Using a part with different resistance or tolerance can alter circuit behavior. Always verify in-circuit.
All suggested alternatives use the same 0402 package, minimizing layout or assembly issues.
Yes, WR04X2002FTL by Walsin is a direct pin-to-pin replacement for RTT022002FTH, matching resistance, tolerance, power, and package.
The best path is a pin-compatible part like Walsin's WR04X2002FTL, which matches all key electrical and physical specifications.
The main risk is using a substitute with a different resistance value or wider tolerance, which can affect circuit performance and requires engineering validation.
