FOJAN
A strong pin-to-pin compatible alternative with matching package, resistance, power, tolerance, and TCR.
RS-05K1500FT is a common 150Ω, 1% tolerance, 0.125W thick film resistor in an 0805 package. Multiple direct and parametric alternatives are available from various manufacturers.
The 0805 package is standardized, making physical replacement straightforward.
Must match resistance, power, and tolerance. Using a 5% tolerance part instead of 1% can cause circuit failure.
This is a common resistor value with many manufacturers, reducing sourcing risk.
Yes, FRC0805F1500TS by FOJAN is a strong pin-to-pin compatible replacement for RS-05K1500FT.
FRC0805F1500TS is the best direct replacement, matching all key electrical and physical parameters.
The main risk when substituting is using a part with wider tolerance (e.g., 5%) or different technology (thin film) without verifying application needs.
