Package and order codeSOIC D, 16 pins, 2500 pieces on a large reelSOP-16, UMW ULN2003A, 2500 pieces on a reelBoth are 16-pin narrow surface-mount Darlington arrays with the same pin functions. Verify the land pattern and reel format before production.
Operating ambient temperature-40 C to +70 C-40 C to +85 CThe target publishes a wider ambient operating range.
Output leakage current at 50 V50 uA maximum at +25 C; 100 uA maximum at +70 C20 uA maximum at +25 C; 100 uA maximum at +85 CThe target has a tighter room-temperature maximum and specifies its high-temperature limit at +85 C.
Thermal resistance88.6 C/W junction-to-ambient for the SOIC D packageNo junction-to-ambient thermal resistance or derating table found in the reviewed documentThermal headroom for multi-channel loads must be established separately from the source datasheet.
ESD ratings2000 V HBM and 500 V CDMNo ESD rating found in the reviewed documentThe reviewed UMW document does not support an ESD-equivalence claim.

FAE documentary review accepted for the exact TI ULN2003ADR and UMW ULN2003A order codes. Both are seven-channel, 50 V, 500 mA Darlington arrays with clamp diodes and the same 1B-7B, E, COM and 1C-7C pin functions. The reviewed electrical limits match for input current, saturation voltage and clamp forward voltage. The target lacks published thermal-resistance and ESD ratings, and package/land-pattern details must be checked. Document review only; not bench, reliability or production qualified.
