I have the infamous Stern Indy Cairo Swordsman issue pop up recently. I saw a tech post by someone which said to replace the P/N BSS123 Mosfet chip with transistor type MMST3904 for Q1. I'm just seeing this type:MMST3904-7 Transistor Bipolar NPN 40V 0.2A SC70-3 listed. Would this be a suitable replacement?

Compare the specs. Although they look cross compatible, I'm not sure why

the designation "-7" was added. The original part number appears to be
obsolete so perhaps there is a minor change.
Digi-key.com has spec sheets on both.
