Yageo
A strong pin-compatible match from Yageo with identical key parameters, but requires review of the power rating for your application.
Find and compare alternatives for the RS-03K1503FT, a 150kΩ 1% 0.1W 0603 thick film resistor. This guide reviews pin-compatible options and parametric alternatives from Yageo, UNI-ROYAL, and more.
Substitutes have the same power rating. If the application runs close to the 0.1W limit, this is a reliability risk.
All top candidates use the standard 0603 package, ensuring form and fit compatibility.
The 150kΩ 1% 0603 resistor is a common value available from multiple major manufacturers like Yageo and UNI-ROYAL.
Direct replacement for RS-03K1503FT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The Yageo RC0603FR-07150KL is the strongest candidate, matching all key parameters including technology. However, its power rating is the same as the target, which may not provide sufficient design margin for all applications.
The primary risk is the lack of a power rating safety margin, as the best substitutes offer the same 0.1W rating as the target, not a higher one.
