UNI ROYAL
Functional alternative with identical electrical specs but in a smaller 4D02 package, requiring board redesign.
Reviewing alternatives for the UNI-ROYAL 4D03WGF1000T5E, a 100Ω ±1% 4-resistor array. Key considerations for substitutes include package size, resistance tolerance, and power rating.
Some candidates use a smaller 4D02 package, requiring a PCB redesign.
Candidates may have different resistance or wider tolerance, requiring circuit validation.
Direct replacement for 4D03WGF1000T5E should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
No direct drop-in replacement found. Alternatives require either board layout changes or accepting different electrical parameters.
The primary risks are physical incompatibility due to different package sizes (4D02 vs 4D03) and electrical deviations in resistance or tolerance.
