I've created the new BOM version with the following replacements. Please use the updated BOM file!

1 - SZYY0805G (C434432) 2 - no replacements in stock; Andrey presumably has some of ZXMS6005SGTA in the stash 3 - S1206-F-5.0A (C553924) 4 - GS8551-TR (C157715) MAYBE - it's not the best replacement, it's better to ask @mck1117 if it fits... 5 - CL10A106MA8NRNC (C2922482) 6 - 74LVC4245APW,118 (C6091) 7 - SN74LVC2G17DCKR (C50714) 8 - Q601 is not needed, because Q600 is back in stock (C2649436)! 9 - WST4045 (C719073)

number 4 looks OK to me, very very slightly worse, but not really in ways we care about!
