Yageo
Matches resistance and package, but has a weaker temperature coefficient requiring review.
Find and compare alternatives for the MF0W4FF2002A50, a 20kΩ 1% 1/4W axial metal film resistor. This page provides analysis of potential substitutes, highlighting key parametric differences for engineering review.
TCR mismatch is common in available alternatives.
High-power axial parts may be larger; SMD parts require redesign.
No direct, verified drop-in replacement has been identified. All candidates require engineering review due to parametric differences like TCR or package type.
Review axial candidates with matching resistance/tolerance, but verify TCR and physical size before use.
The primary risk is degraded circuit stability due to substitutes with a higher Temperature Coefficient (TCR).
