LM1117-1.8V
LMV331
BC817-16
BC807-16

All are SMD components what standard/DIP components can i replaced?

TIA
 

The LM1117-1.8 has its TO220 equivalent, namely the LM1117T ..
If you can't get it, try to use the LM317 (with two external resistors) ..

The LMV331 (single cmparator) can be replaced by the LM2903 or LM392/3, both dual comparators, but both can work with similar supply voltages as the LM331 ..
If the supply voltage is around 5Vdc you can also consider the LM311(211, 111) ..

BC807 can be replaced by any general purpose PNP transistor, try BC557, BC558, PNP100 etc ..

BC817 can be replaced by any general purpose NPN transistor, try BC547, BC548, 2N2222, NPN100 and so on ..

Regards,
IanP
