Yageo
A strong pin-to-pin alternative with matching package, resistance, tolerance, power, and technology.
FRC0805F1803TS is a general-purpose 180kΩ, 1%, 1/8W thick film resistor in a standard 0805 package. Finding a suitable replacement involves matching these key parameters and the physical footprint.
Using a part with different resistance or technology (thin film) requires circuit validation.
All candidates use the standard 0805 package, ensuring physical compatibility.
Yes, RC0805FR-07180KL is a direct replacement candidate for FRC0805F1803TS, sharing the same resistance, tolerance, power, package, and technology.
The most direct path is RC0805FR-07180KL, which matches all critical parameters. For improved performance, consider the thin-film upgrade RT0805BRD07180KL.
The main risk when substituting is selecting a part with a different resistance value or technology (e.g., thin film) without verifying circuit compatibility.
