Did anyone find something ?
Meanwhile, the SN74AUP1G00DCKR (U4902) on the way to Digi-Key have
arrived and they have plenty of stock of this non-stock item now.
I've thus lowered its priority in bom/research/STATUS. Good things
come to those who wait :-)
Alas, the nice Murata 10 uF 10 V X5R 0805 capacitor is no longer
available. I've added an equivalent part from Kemet. Our score is
now:
SVN Rev -- No source -- -- Digi-Key -- -- Farnell --- --- Mouser ---
Short Missing Parts Price Parts Price Parts Price
r5913 8 11 85 1436 2 UKP 52 1 134
Now, let's move forward with the replacements. Is everybody fine
with the following two substitutions ?
Samsung K4M51323PC-DG75 -> Micron MT48H16M32LFCM-75:B
Proconn SMSN16-J0-2214 -> Amphenol 101-00492-20
The former needs a slightly different footprint (the package outline
changes, the balls don't), while the latter needs an update of the
schematics, the footprint, and probably also the circuit symbol.
