# 5-pin DIN socket advertised as MIDI, not the same as on my MIDI gear

I bought a 180-degree 5-pin DIN chassis-mount socket dirt-cheap for a project, but I saw that it looks quite different from the MIDI outs on my MIDI gear; I did some research but couldn't find any info on MIDI plugs being any kind of specialized DIN shape, just 5-pin 180-degree DIN.
I just ordered another chassis-mount socket from UK, advertised on their site specifically as being for MIDI, but it's the same as the cheap one I got before, and doesn't appear to be the same as on my gear. I currently don't own a cable, so my own tests are pending. But when they say MIDI is 180-degree 5-pin DIN, is it really exactly the same or is there some other specification that needs to be made between different layouts of 180-degree 5-pin DIN? Diameter of the semicircle? Size and shape of the aligning nub?
I can easily believe no one has ever actually ordered this product and tried to use it since the UK online store has been running! What I can't believe is that this information doesn't exist anywhere within Google's reach. It's out there somewhere.

• I've seen two types - one larger than the other. – Andy aka Apr 11 '16 at 10:21
• @Andyaka Mini-DIN is not the same as DIN, and would be advertized as such. – CL. Apr 11 '16 at 10:21
• @CL. It may be advertised as such but the question I have is did the Op notice that subtlety? – Andy aka Apr 11 '16 at 10:26
• Add a photo of both connector types. – Brian Drummond Apr 11 '16 at 11:45

"DIN" is the name of the German standardization body; all the relevant dimensions are exactly specified in DIN 41524, or nowadays IEC 60130-9.

The cable's connector has five simple pins:

There are different ways of aligning the springs that hold these pins:

However, what matters are the positions of the actual pins and holes, and those are always the same:

• Thanks for the direct answer! May I ask if you found this info online, and where? Or do you know from your experience? So, when I pick up that cable next week, if it doesn't go into the holes of the panel mount connector I bought, I can complain to Hobbytronics UK. – Chuckk Hubbard Apr 13 '16 at 18:36
• This is just from various connector datasheets, found via Google. – CL. May 21 '16 at 14:46

Easily found through Google, the current MIDI spec's are available here: of which page 3, excerpted below, describes the connectors:

• @ChuckkHubbard: Part 1. If you're still waiting, it appears you missed CL's reply of 11 April, where he cites his source as DIN itself, with his reference being: "DIN 41524, or nowadays IEC 60130-9." If you want to pay to download the document it should give you everything you need. If you choose not to, Switchcraft's site can get you started by giving you the bolt circle for the 180$\degree$ 5 pin female. Part 2 follows... – EM Fields Apr 14 '16 at 21:05
