UNI-ROYAL
An upgrade with tighter tolerance (±1%), but in a different package (4D03) that requires layout verification.
Finding a replacement for the UNI ROYAL 4D02WGJ0104TCE resistor array requires careful checking of package dimensions. While alternatives with matching electrical values exist, they often come in different package sizes, necessitating board layout verification.
Candidate packages (4D03) are different from the target (4D02) and require PCB layout changes.
Key electrical parameters like resistance and power are matched or improved.
Direct replacement for 4D02WGJ0104TCE should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Upgrade to 4D03WGF1003T5E for better tolerance, provided your PCB layout can be adapted for the larger 4D03 package.
Package mismatch is the main risk. The 4D02 and 4D03 packages are not interchangeable without board redesign.

| Feature / factor | 4D02WGJ0104TCE | 4D03WGF1003T5E | 4D03WGJ0104T5E | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 4D02 | 4D03 | 4D03 | 4D03 — Different package size, requires layout verification.; 4D03WGJ0104T5E: Different package size, requires layout verification. | |
| Tolerance | ±5% | ±1% | ±5% | ±1% / ±5% — Tighter tolerance is a performance upgrade.; 4D03WGJ0104T5E: matched | |
| Resistance | 100 kΩ | 100 kΩ | 100 kΩ | 100 kΩ — matched; 4D03WGJ0104T5E: matched | |
| Pinout | Unknown | 8 | Unknown | 8 / Unknown — Candidate pin count is known, target is not.; 4D03WGJ0104T5E: Pin count for both parts is undefined. | |
| Power | 1/16 W | - | 1/16 W | 1/16 W — Power per element. |
Verified drop-in options for 4D02WGJ0104TCE are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
