Yageo
Near-identical precision resistor with a slightly different resistance value (50kΩ).
The Yageo RT1206BRD0749K9L is a 49.9kΩ, 0.1% tolerance, 1/4W thin film resistor in a 1206 package, used in precision applications. Alternatives exist but require careful review of resistance value, tolerance, and TCR.
Target is a precision part; substitutes with wider tolerance or higher TCR can affect circuit accuracy.
The 1206 package is a standard, and many alternatives are physically compatible.
Direct replacement for RT1206BRD0749K9L should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
For precision circuits, evaluate RT1206BRD0750KL (50kΩ). For non-critical circuits, consider RC1206FR-0749K9L (49.9kΩ, 1%).
The primary risk is performance degradation in precision circuits due to changes in resistance, tolerance, or TCR.
