Question: An example.
I used Intellifet by Diodes Inc.
They are logic level mosfets, with builtin protections.
There are many components, with slight different ratings.

Let's say many of these components fit my project.
I want to sort them not by their electrical ratings, but by their "popularity"

> 
> selling volumes
> 
> 
> availability in Europe from many vendors.
> 
> 
> 

Are there any source of these informatioms ?

Note: I need to find a solution to speedup the choice made by "visiting the distributors web sites".
Small orders : each component, from 10 to 50 pieces.

Answer: 
Go to a distributor, pick components that are "active" and sort by stock level. Compare several. Look for **second sources** where appropriate and compare, including details. A part may be very popular, but not in a certain package or temperature range. 

Double check the manufacturer's website to be sure that the part is recommended for new designs. 

Carefully consider who else is likely to be using the parts. If they're aimed specifically or mostly at something with a design life of 6 months (eg. cell phones or whatever the next big thing is) and your product has to be available for 15 or 20 years, there is a good possibility it will be obsoleted before you even get many out there. 

There is still an element of chance here, it's possible that there is a shortage today of the part you should be specifying and it will be the best one in 3 months when your product ships. There's no one way of dealing with that sort of thing except keeping an eye on the market. Right now some passives are in short supply. 

As far as actual sales volumes, those numbers are not freely provided by anyone, as far as I know. Occasionally teasers will be quoted from very expensive reports (such as market share of microcontrollers) and you can read the trade press for that sort of thing, but it's not terribly reliable and often not current or has some kind of baked-in bias by the folks who paid for it.
While its a good idea to use parts that everyone else is using, this can also be a drawback. For example: This year Murata [discontinued](https://www.ttiinc.com/content/ttiinc/en/resources/marketeye/categories/passives/me-zogbi-20180302.html) their low end line of capacitors the GRM series. The MLCC capacitor market was already near a shortage, they discontinued their line and everyone had to switch. The line was popular because it was cheap, and the voltages were high. If everyone buys at the same time then you'll be left out and you won't be able to build your design. 

You probably want to talk to a supply chain management company for electronic parts. [Silicon Expert](https://www.siliconexpert.com/node/60) is one, but they are expensive and will only save you money if you are buying millions of dollars of parts. They will be able to tell you which are the most popular parts, and they'd better be able to do that, because they are expensive (but worth it if your a big company)

The other one that is more affordable is [ciiva](https://ciiva.com/), they should be able to give you the information you desire.

But more than that, they will be able to give you cross references on parts and keep track of End Of Life (EOL).
