Yageo
Needs validationlow risk
A strong pin-compatible alternative with matching 0.1% tolerance and 25ppm/°C TCR in a 0603 package.
Best Alternatives to ARG03BTC3002
Finding a substitute for the Viking Tech ARG03BTC3002 precision resistor requires matching its 30kΩ, 0.1% tolerance, and ±25ppm/°C TCR in a 0603 package. Several options exist with varying degrees of compatibility.
AI replacement insight
Package risklow
0603 is a standard, widely available package.
Electrical riskmedium
High risk if using a non-precision (Thick Film, high TCR) part. Low risk with the top recommended candidate.
Can it be replaced directly?
Yes, Yageo RT0603BRD0730K1L is a near-direct replacement, but its resistance is 30.1kΩ, not 30kΩ.
Best replacement path
Use Yageo RT0603BRD0730K1L, after verifying the minor 0.33% resistance difference is acceptable.
Main risk
The primary risk is using a substitute with degraded precision, specifically a higher TCR or wider tolerance.
