LIZ Electronics
Pin-compatible alternative from LIZ Electronics with matching resistance, tolerance, power, and package.
The Walsin WR04X1003FTL is a general-purpose 100 kΩ, 1% tolerance, 1/16W thick film chip resistor in a standard 0402 package. This component is widely used in consumer electronics, computing, and telecommunications.
Using a part with wider tolerance or different technology requires review.
0402 is a standard package with excellent availability.
This is a very common resistor value and package combination.
Direct replacement for WR04X1003FTL 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 WR04X1003FTL, then review parametric alternatives for package and electrical fit.
The main risk is using a substitute with a relaxed tolerance (e.g., 5% instead of 1%), which could compromise circuit accuracy.
