Yageo RC0805FR-07390KL is a strong alternative with matching 390kΩ resistance, ±1% tolerance, and 0.125W power in an 0805 package.
FRC0805F3903TS is a general-purpose 390kΩ, 1% tolerance, 0.125W thick film chip resistor in an 0805 package. This page provides a review of potential alternatives, including pin-compatible options and parametric variants.
Low for pin-compatible matches; medium for parametric variants.
All reviewed candidates use the same 0805 package.
Direct replacement for FRC0805F3903TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The most direct path is RC0805FR-07390KL, which matches all critical specs. For higher precision, RT0805BRD07390KL is an upgrade but requires checking technology compatibility.
The main risk when choosing an alternative is selecting a part with relaxed parameters, such as wider tolerance or a different resistance value, without verifying circuit compatibility.
