You're going to model the internal transistors and resistors of each pair?
Not having much luck, so I'll turn to Twitter: I need to model the Darlington pair from a ULN2003 array. The NPN BJT models I have available are 2SC1815/945, 2N3565/3643/3704/3904/5190/4401/4124/5210/6292, and BC237B/548C/817-25. Which would be the closest to use?

How detailed are the models? What behavior are you hoping to capture in the modeling? What load are you driving? (Relay, inductor, lamp?) Looking at the datasheet, I don't see anything really "special" about these devices.

Usually, 2N3904 is a good bet. In this case, I'd suggest 2N4401, since the current capability is a little higher.
