Hello,I have the following connector called CONN,SMA,FEM,W/.500 FLNG in the attached datasheet as .
what is the fornmal name for this connector so i could find and use their 3D step file?
Thanks.

 

Whose 3D step file?

What makes you think that there is some universal, unique "formal name" for the part?

 

Hello , I need to use the following connector in my PCB.I posted also photos .
CONN,SMA,FEM,W/.500 FLNG
Is there some component which matches the description on the name from the data sheet and photos?
Thanks.

 

Sure. A component that matches that name is "CONN,SMA,FEM,W/.500 FLNG".

That's as good a name as anything else. Each manufacture is going to use their own naming convention. Vendors may or may not use the manufacturer's name in their product listings. Whomever the unspecified "their" is who has this 3D step file you are referring to will use their own conventions.

You know what the part is. Look at the available items in this step file and see if you can find a match based on what the part is, not some string of characters.

 

I will hazard a guess.
SMA connector (SubMiniature version A), female, with 0.5 inch flange.

 

A common name would be " Flange mount female SMA" connector.
