Pin-compatible 0402 resistor with matching 38.3kΩ resistance, 1% tolerance, and 1/16W power rating.
Finding a replacement for the Yageo RC0402FR-0738K3L, a 38.3kΩ 1% 0402 resistor, involves matching key electrical parameters and package size. Several options exist, from direct pin-compatible parts to parametric alternatives.
Risk is low for pin-compatible parts, but medium for parametric alternatives due to resistance deviation.
All suggested alternatives use the same 0402 package, ensuring physical compatibility.
The target and alternatives are common value resistors from major manufacturers.
Direct replacement for RC0402FR-0738K3L should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Start with Datasheet verified or Strong match candidates for RC0402FR-0738K3L, then review parametric alternatives for package and electrical fit.
The main risk is using a parametric alternative with a different resistance value, which could affect circuit timing, biasing, or feedback loops.
