Do not trust the Farnell Eagle Libraries!!!

Hi Andrew,

I don't see it as part of the standard libraries, which URL did you use to download it?

EDIT:

I see it on the site; you're right, it should be corrected.

Personally I just make my own parts always (apart from Rs and Cs).

It's not in the standard libraries.I referred to the Farnell libraries. It's in their Diodes Inc library.

Hi Andrew,

It sucks when you run into something like this.  My rule of thumb from many

years of experience is "DO NOT TRUST ANYONE'S LIBRARIES BUT MINE".

Our internal process is that any device we use MUST come from our library.

We sometimes will copy things in from publicly available libraries but then

we have a whole checklist of things that we go through to make sure they

are right.  Often times it's easier to just create them from scratch.

This isn't just an EAGLE issue either, we treat Altium exactly the same

way.  Engineers should be skeptical.  At the end of the day, if the board

doesn't work, people don't really care why.  You were supposed to create a

board that worked and it didn't.  That is usually where the conversation

ends.

For hobbyists, it's a bit different.  But with limited $$$ you'll want to

make sure what you send out is right.  So the same rule should really

apply.

Cheers,

James

For a really good time, use a standard library part that's been changed

since the last library release, with no change notice.

That's why James is SO right. The best hour or two you will ever spend on

the Eagle learning curve is the hour or two spent learning how to properly

make your own libraries, even if they're nothing more than carefully checked

cut-n-paste parts from existing Eagle libraries. At a previous employer,

they used a fancy library that cost five figures with their PADS layout

package, and it was still a mess of inaccurate footprints and pin

assignments. I've seen library parts DIRECT FROM THE IC MANUFACTURER that

didn't match the datasheet, or the part. In the end, the only one who cares

about your board and your money is you. I've learned that lesson myself the

hard way.
