Yageo 30k 0603 thick film looks close, with tighter tolerance pending FAE check.
Best Alternatives to 0603WAJ0303T5E
0603WAJ0303T5E is a 30kΩ ±5% 0.1W 0603 thick film resistor. Several 0603 candidates look close, but PDF and power derating checks are still required.
AI replacement insight
Electrical riskmedium
Check power, pulse, voltage and value shift.
Package risklow
0603 candidates match; 0805 does not.
Firmware risklow
Passive resistor; no firmware.
Sourcing riskmedium
Some evidence is distributor-only.
Can it be replaced directly?
Direct replacement for 0603WAJ0303T5E should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Prefer 30k, 0603, thick film parts with equal or better tolerance and verified voltage, temperature, pulse, and power margin.
Main risk
Equal 0.1W power rating may not meet the 1.5x derating rule.
