A functional alternative with similar electrical ratings but fewer channels and a different package.
The Toshiba TBD62083AFWG(Z,EHZ is an 8-channel sink driver in a SOP18 package. Finding a direct, pin-compatible replacement is challenging, and alternatives typically require board redesign.
No candidates with matching package and pinout were found.
Must distinguish sink (low-side) from source (high-side) drivers.
The specific 8-channel SOP18 configuration may be difficult to source.
No direct drop-in replacement is available. All similar parts require board redesign.
Redesign with a common 7-channel sink driver like the ULN2003 series if the 8th channel is not used, or use two smaller drivers.
The primary risk is functional incompatibility, as similar part numbers can be source drivers instead of sink drivers.

| Feature / factor | TBD62083AFWG(Z,EHZ | ULN2003D1013TR | Alt 2 | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Function | Sink Driver | Sink Driver | Sink Driver — Both are NPN Darlington sink drivers. | ||
| Channels | 8 | 7 | 7 — Candidate has one fewer channel. | ||
| Package | P-SOP18-0812-1.27-001 | SO-16 | SO-16 — Not a drop-in replacement; requires board redesign. | ||
| Voltage | 50 V | 50 V | 50 V — Maximum output voltage matches. | ||
| Current | 500 mA/ch | 500 mA | 500 mA — Maximum current per channel matches. | ||
| Temperature | -40 to 85 °C | -40 °C to 85 °C | -40 °C to 85 °C — Operating temperature range matches. |
No direct drop-in replacement has been identified. Functional alternatives like the ULN2003 series exist but have fewer channels (7 vs. 8) and different packages, requiring board redesign.
