DC jack mounting

[Erl]

I'm working on a project, and I need a DC jack that can handle 24 volts and 4 amps DC.

It hasn't been all that easy to find at a decent price. Here's one:



I assume that you're supposed to solder cables to the jack, since the solder lugs have through-holes. There are other jacks that have another type of solder lugs that look more appropriate for through-hole soldering, like this one:



So, with the first jack, if it is made for cable soldering, how are you supposed to fasten it to a case?

Or have I misunderstood something?

Thanks for any advice,

The first jack is intended to be mounted vertically. Check the datasheet for the PCB layout.

Why then are there holes in the mounting lugs, rather than 'shoulders' like on the second one?

Won't the lugs stick out needlessly far on the back side of the PCB?
