Sourcing Corrent Component Packages

So I got one of these in the Free PCB give-away, and am having a little difficulty translating from the internal package names to manufactures packages from this page:
http://dangerousprototypes.com/docs/Log ... n_overview

After being sent to this page: http://dangerousprototypes.com/docs/Partlist

I think the SMC_A looks like a 1206 Tantalum package, looking at the board images.  So something like:
http://search.digikey.com/scripts/DkSea ... -4086-1-ND
And that the oscillator is a 7mmx5mm part like this one: http://search.digikey.com/scripts/DkSea ... -1171-1-ND

I'm also guessing the SO20W means the 0.295" wide package.

Does this sound right?

Hi phirephly,

Thanks for moving to the forum, it's easier to give long-forum answers that other board builders can see too.

The capacitor and OSC look ok. The 74LVC573  is the wide SOIC version, not sure of the width, but I think you have the right one. It is possible to solder the narrow version in the same footprint if you need (arhi did this on his build).
Got a question? Please ask in the forum for the fastest answers.

For the future projects I suggest making the footprint for the wide packages bit different, increase length of the pins by 0.5mm inwards so that you can solder the non-wide part without needing solder bridges to make the connection on one side :) ... it can be done as it is but it is pain in the ...

And wrt LogicShrimp, what I did is send a whole bom to my supplier - what happened they returned email and said - "no idea what these parts are", biggest problem was the ldo, "standard" ldo's they have are 3pin devices, LogicShrimp requires 5pin ldo and those ain't common locally...

so if it can help someone here's the ldo that works :D

btw, Ian, there is a bug in the BOM, the link for the 74LVC573 (SO20W) is the link to the sram chips and not to the 74LVC573 ... would be cool to fix that with link to proper part :)

Thanks, fixed. It would be great to have our partlists well linked on the wiki, it's certainly a goal :)

Yes, the wiki's good place to add links to all parts .. and to different sources (farnell, digikey, mouser, avnet etc)

I'm working on updating the master partlist now. It was a database dump of my previous 5 years of mouser orders with lots of duplicates. I'm working on just adding commonly used parts with pictures and then expand from there. That should make it easier to link individual project lists, as well as reorder parts for the lab.

i still have not found a compatible Ethernet jack for the hanrun part. I'd like to see it sold @ SFE and seeed

Well I got the PCB and the last of the parts today, and it seems that everything at least fit: http://kennethfinnegan.blogspot.com/201 ... build.html

I'm still waiting for my PICKit to program it with, but the hardware's done.
