FOJAN
Parametric alternative in the same 0603 package with a lower resistance of 1.69kΩ.
Find and compare suitable parametric alternatives for the 0603WAF1871T5E, a 1.87kΩ 1% 0.1W 0603 chip resistor. Review key parameter differences before making a substitution.
Resistance value differs and power rating lacks safety margin.
All candidates use the same 0603 package.
Candidates are from active manufacturers like Yageo and FOJAN.
No direct drop-in replacement is identified. All candidates require review due to different resistance values and lack of power rating margin.
Use a parametric alternative with a slightly different resistance value after engineering validation.
The primary risk is the change in resistance, which could alter circuit timing, biasing, or feedback loops.
