UNI-ROYAL
A strong pin-compatible alternative with identical key parameters from a different manufacturer.
Find and compare replacements for the FH RS-03K3011FT, a 3.01kΩ 1% 0603 thick film resistor. This page provides pin-compatible options, functional alternatives, and a detailed analysis of substitution risks.
Risk arises if changing from thick to thin film, or relaxing tolerance from 1% to 5%.
All reviewed candidates use the same 0603 package, ensuring form-fit compatibility.
This is a common resistor value and package with many available manufacturers.
Direct replacement for RS-03K3011FT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use a parametrically identical 0603 thick film resistor like FRC0603F3011TS or 0603WAF3011T5E for the most direct replacement.
The main risks are inadvertently selecting a part with a different technology (thin film) which may have different pulse handling, or a part with a wider tolerance (e.g., 5%) which could affect circuit precision.
