A 3.9kΩ, 1%, 0.5W resistor in a matching 1210 package. Review power dissipation in your application.
Find substitutes for the 1210W2F3901T5E, a 3.9kΩ 1% 0.5W 1210 thick film resistor. This guide reviews pin-compatible and parametric alternatives, highlighting key differences for safe replacement.
Low for matched parts, medium for parametric alternatives due to value/tolerance shifts.
Kept candidates use the same 1210 package, ensuring physical compatibility.
Direct replacement for 1210W2F3901T5E should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
FRC1210F3901TS is a strong candidate, matching all key specs including package, resistance, and tolerance. However, power rating is identical, so application derating should be confirmed.
The primary risk is ensuring the substitute's power and voltage ratings meet the application's safety margins. Parametric alternatives introduce resistance and tolerance deviations.
