My first post and my first question:

I am planning on soldering the Amiga 4000 replica project made by Acill. I ordered most of the components with the BOM of John Taylor.
But still this EIAJ package is confusing me a little bit.

74F86, SM, EIAJ package; component: U711
74HCT174, SM, EIAJ package; component: U177, U354, U907
74LS74A, SM, TTL, EIAJ package; component: U351
IC, Linear, LF347, EIAJ package; component: U402

What can be used as replacement parts hence the term SOIC is not 100% specific towards interchangeability ?


thanks in advance
