If you really want a reliable device then take the data sheet and create
it yourself.

Good morning mr. Paschedag,
I'm sorry for the tone used in my previous e-mail :-) I did not want to look arrogant or look like someone who pretends things that are already ready. Sorry again.
In fact I have already created my component eagle file, I just wanted to compare it with an official.

Thank you for your reply.

Yours sincerely

Silvio

No Problem ;-)
I didn't find any library but if you upload your work I might have a
look and compare it with the data sheet.

Hi Silvio,
you don't need a link you can upload a file as zip file because the lib file was not allowed.
For me, i don't click to this unknown link there, a lot of virus may be on there.

I had a short glimpse at your file and it looks quite OK.
You should observe that the pad numbers in the data sheet are given at
bottom view.
Eagle is always looking from top! Body size is OK but I didn't check the
pads. Attached is a suggestion that might help you (pads renumbered) ;-)

Hi,

the part is wrong.
Also the footprint is wrong.
A device have pins that begins from 1 not from elsewhere and goes numbering to the last pin; here the exposed pin will get the last pin number.
Also it is missing the symbol also the connection to the footprint.
The symbol can have pin names instead of pin numbers, because that are functioning names. Then the schematic will be easier to read.

If you use the advanced editor you can attach files.

If you haven't a packaging program:
www.winzip.com

Best Regards,
Gerald

Hi Silvio,

please refer to the drawings in the datasheet, also the drawings in the additional information.
There will be described how you can draw your footprint.

Here in this drawing the pad has a template at the inner side a round shape an at the outside a rectangle.
So you easy draw this - a SMD round pin and a polygon connected on this round pin (this polygon gets the same pin name, number).
Please read also the Eagle manual - "how to create complex SMD pins"...
After that - make 5 copies at X-angle from left to right (from east to west, then 5 copies Y-angle from bottom to top (from south to north),
then 5 copies on  north from west to east, and last 5 copies from north to south on the east side.
In the middle then you create the exposed pad.
Be careful with the grids. - If the datasheet shows you in mm then you set a fine grid in mm
(eg. the pin grid is 0.5mm - then make the dimension grid so fine that you can divide into this grid without rest. ->> n / 2 = xxx.xxxxx)
For me i calculate to fine grid 5 numbers after comma. This allows you to multiply back to the top number at any time.
->>> see also inch / mm.
->>> see also top or bottom, right or mirrored
Eagle looks every time from top to bottom.
You know about Mr. Wilhelm Conrad Röntgen?  ;) That is what you need in your eyes.
Do you know the mirrored focussing? Well it's a very fine feeling. B-)

I wish you all the best.
After that we can talk once more.

Best Regards
Gerald
