Source for USB mini-b receptacle
Mark Borgerson
to find a source for the mini-b receptacles. These are the very
small receptacles (the connector is 2mm by 1.5mm) used on MP3
players and digital cameras.
Google doesn't seem to find any good links to the type of receptacles
I'm looking for---although there are references to receptacles with
5 pins instead of the 4 I'm looking for. The product finder at usb.org
doesn't find anything when I look for mini-b connectors. Support for
these connectors is fairly new, so perhaps the manufacturer web
pages aren't up to date yet.

A "receptacle" sounds too academic for this day and edge,
try "socket" or "connector".

The part we are using is a Kuon Yi KS-001K-BNB. This part was sourced by our
factory in China. It is a standard 4-pin (with two extra mounting "pins"
which are electrically part of the casing and should be grounded). I don't
know how much that helps you, but it's a start.
Also try Foxconn, http://www.foxconn.com/products/product.asp?Prefix=UC for
their type-B receptacles.This part again has four actual pins and two
mounting pins. The part I originally specified in my design was Foxconn
UC112C-K0 but this is a right-angle part and our casing design needed to
change to a "straight up" part (insertion perpendicular to board). Foxconn
appears to make only two such parts, and both are right-angled.

... uh, nevermind, I thought you were talking about regular type B.
Try Hyosung http://www.hyosungelec.com/eng_products/connector/con2.htm - I'm
pretty sure they have the mini connectors.

I've got the same problem ;-) I found a few suppliers
but I emailed them and nobody except Molex has replied.
Since I make it a policy never to source components from
companies that ignore my emails I'm going to choose the
Molex part to design-in.
Also it doesn't have pins on the underside which means
my design has absolutely needs no holes in the PCB, it's
completely SMD. This might be important for your design
if it's low profile.
Cheers,
Mark.

The On-the-go spec provides for a *standard* mini-b
connector (the current connectors are not standardized and
may vary from device to device). You may want to contact
the USB-IF regarding the new OTG addition to the USB
spec.

I have the same policy which is why, for a new design, I choose Molex a few months (two or
three) ago for their stacked USB downstream connector which fitted my wishes perfectly. I got
a quote and deliverytime, all seemed acceptable and fine. Up until a few weeks ago when they
appeared obsolete! Words of unhappiness!!
Don't get me wrong, this is not to say don't go for Molex, absolutely not. It's just to say
that I had to abandon my principle on this point and had to go to a non-answering company.

I actually got a response from Molex on my request for samples,
so hopefully, I will be able to test them. I like the SM design
and have worked it into my PCB layout. I still haven't
found a Molex distributor that stocks the part, though! ;-(
The 5-pin Mini-B is described in the new Engineering Change
Notice from USB.org, so I will go with that design. Doesn't
match the connector on my MP3 player, but I'll be more likely
to find cables to match a connector approved by USB.org.

Bummer! Did they give you samples too, string you along?

It's a sad fact of life that exceptions always have
to be made to any rule ;-)
Hopefully they won't obsolete this part as it's a
usb.org standard component. They did take many weeks
to send me the samples, so I wasn't that impressed
with their service even though they did respond to
my query.
Best Regards,
Mark.

Bummer. Maxim, Xilinx, TI and others usually manage to get me
samples in less than 10 days. Shortly thereafter, I usually
get a call from a sales rep who wants to sell me the part.
A lot of semiconductor firms also have online sales for the
quantities I need (50 to a 100 pieces at a time). I wish
Molex did the same thing.
For such simple devices, sockets and connectors seem to take
an inordinate part of my engineering effort! ;-(
Have you found a distributor who actually stocks the Mini-B part??

Yep, I had my samples which made me a happy man (I am not that difficulkt to please! :-) ).
And yeah, I know, it is a risk of todays business strtegies I guess. But nevertheless,
(...starts whining, there may even be a slight sobbing...) why me!! Why This Part! :-)
Cheers,
Best of luck to you,

Thanks for the pointers. I ended up ordering from Lumberg USA--
