The existing board design uses MMBT4401 devices. Now I need to add=20 another transistor to the board and its hard to work with the SOT-23=20 packaged MMBT parts. Much easier to stretch a leaded transistor to=20 reach the various nodes. >Those thin through-hole packages are/were mostly the province of >Japanese makers, so if you really want such a thing, try 2SCxxxx Yeah - the DTC parts I currently use are Japanese-made. But I didn't=20 have any part numbers handy and a quick Google search didn't suggest=20 any suitable devices. >Eg. 2SC1741 (2mm thin) Excellent! I'll start with that. >But most of that stuff is probably getting harder and harder to find, >so I'd be very reluctant to commit to it in a new design. The TO-92 >will be around for a very long time, as will SOT-23. This is to fix a design change. The next board version will include=20 the extra SMD devices. But I've got a bunch of stuffed boards here=20 that would otherwise be scrap.
