    Hi lgendre, no the MJE13007A wont work because its not a Darlington type transistor so its gain (hfe) is too low. Ive tried a lot of transistors & failed until I found & tried 2SD1071. They are cheep I purchased 10 of them for $12.87 + $4.95 freight on Ebay from China. I suspect the Atom module used a custom made darlington transistor as it just had (atom A1) on it.
