UNI-ROYAL
Matches all key parameters including resistance, tolerance, power, and package, making it a strong pin-to-pin alternative.
FRC0805F1003TS is a general-purpose 0805 thick film chip resistor from FOJAN with a 100 kΩ resistance, ±1% tolerance, and a 0.125W power rating. It is suitable for a wide range of electronic applications.
Using a resistor with 5% tolerance instead of 1% can affect circuit accuracy. This is the most common risk.
All candidates use the standard 0805 package, so physical compatibility issues are unlikely.
This is a very common resistor value and package, with many suppliers available, reducing sourcing risk.
Yes, several direct pin-compatible replacements exist for FRC0805F1003TS from manufacturers like UNI-ROYAL and FH (Fenghua).
Use a pin-compatible part like UNI-ROYAL's 0805W8F1003T5E or FH's RS-05K1003FT, which match all key specifications.
The primary risk is substituting with a part that has a wider tolerance (e.g., ±5%) when the application requires ±1% precision.
