/diy/ - Do It Yourself

>>2763827
I've tried to find the original parts, namely UPA1436H and UPA1437H. They're out of production and the only shop I could find that still sells them has a minimum order value of US$250.
Since each of them has two separate darlingtons in one package, my next idea would be to replace them with discrete parts with the same (or very similar) characteristics.
They're well documented, alldatasheets.com has docs on both the NEC-made version used in my printer, as well as a Renesas-made variant with the same part number and values.

Anybody here with experience on transistors who can tell me about possible pitfalls going this route?
