UNI-ROYAL
Needs validationhigh risk
Functional alternative with matching resistance and tolerance but in a much larger package, requiring board redesign.
Best Alternatives to 0201WMF150JTEE
Finding a substitute for the UNI-ROYAL 0201WMF150JTEE, a 15Ω ±1% 0.05W resistor, requires careful attention to the 0201 package. While functional alternatives exist, no direct drop-in replacements have been identified.
AI replacement insight
Package riskhigh
Candidate packages (0805+) are not compatible with the 0201 footprint.
Electrical riskmedium
Some candidates have weaker tolerance (±5% vs ±1%) or different resistance values, requiring circuit validation.
Can it be replaced directly?
No direct, pin-compatible replacements were found. All potential alternatives require a PCB layout change due to different physical package sizes.

Main risk
The primary risk is the physical package mismatch. The target is a 0201 package, while candidates are much larger (0805, 1206, 2512), preventing drop-in replacement.
