UNI-ROYAL
A pin-compatible 6.8kΩ 1% 0.1W 0603 thick film resistor from UNI-ROYAL.
Finding a substitute for the RS-03K6801FT, a 6.8kΩ 1% 0.1W 0603 thick film resistor, involves matching key electrical and physical parameters. Several pin-compatible options and functional alternatives exist from various manufacturers.
Low for pin-to-pin matches; high for parametric alternatives.
All candidates share the same 0603 package.
Multiple manufacturers produce suitable alternatives.
Direct replacement for RS-03K6801FT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use a pin-to-pin candidate like FRC0603F6801TS which matches all critical parameters.
The main risk is inadvertently selecting a part with relaxed tolerance (e.g., 5%) or a different resistance value, which could impact circuit performance.
