I bought a replacement MB on E-Bay because I couldn't find the exact audio jack from any source. The MB used a different CPU, so I un-soldered the audio jack and used it for a replacement on my otherwise fine MB. (I also now have two spares from the MIC, and LINE IN for when the LINE OUT breaks the next tiem.)

.. Also.. Does anyone understand the schematic? It would appear that 2 and 3, and 4 and 5 are closed when no jack is present, and when one is present they would be disconnected? Does that seem accurate?

I should be able to solider those two on my motherboard and get sound throuh the speakers again?

Thanks for the link! Can anyone verify which one it is? I think this looks almost exactly like the dell one does:

If anyone knows! Let me know!

I am unable to verify which part is needed for your system.

Yes, the schematic indicates that the left and right signals from the sound card are brought to the connector. With no plug inserted, these signals are passed on to the internal speakers. If you jumper the NC (normally closed) pins, your internal speakers should be continuously connected to the output of the sound card.

In another thread on the same topic, I responded that in the Inspiron 8000 and others, the jack has a FOXCONN logo, and has 6 conductors. (The items from DigiKey and others only have 5 conductors.) The jack I removed from the E-Bay MB and fit as an exact replacement is a  JA6333L-101-TR. When I measured one of the extra jacks I took off the e-bay MB, the tail length (T/L) is 1.45mm. The 101 in the part number refers to a T/L of 2.4mm, so I would guess that the correct part modifier should be 102, but the extra length could just be clipped off after soldering if a 102 is not available. WhenI checked the schematic of the ones with the R, that stands for Reverse wired, where positions 4-5 are normally open (NO), while the item I have in my hands, has positions 4-5 as normally closed (NC). The packaging code TR indicates the are supplied on a Tape Reel, probably for use in automated equipment. It will be interesting to see what minimum quantity can be purchased!

Now just to be able to buy the item! Good Luck!

I am amazed at this Dell. I took the computer apart tonight to see if I couldn't solider those connections, only to find that there are actually 6 conductors as you said. (In the process I actually ended up removing the processor on accident and bent pins.. but I managed to fix that and not harm anything).

I did snap a few pics of the connector pad, as well as noticed the FOXCONN on the mic casing. Hopefully soon we can find a suitible alternative or replacement that is cost effective as you said JMB.

Concerning your connections, on the part you have does that mean that I would be able to connect just the 4 and 5th pin to get sound through my speakers? Or are you saying that the stock connector is NO so not having it would not effect not having sound?

I am really just hoping to get sound back through my speakers at this point.. if I want other sound, I should just get a USB soundcard.

The part I have is indeed the JA6333L series 3 band  conductor jack. Here is the link to the PDF schematic and PCB layout:

http://www.foxconn.com/Catalog/Spec/connector/JA6333L-101-TR.PDF

On the schematic, pins 2-6 and 4-5 are normally closed (NC) until a headphone plug is pushed into the jack and makes contact with pins 2 and 3 and opening the connection 2-6 and 4-5, thus turning off the internal speakers. From your picture of the place where the jack was, it didn't look exactly like the bottom side of the JA6333L connector that I have, or as seen in the PCB hole layout.

 

AJ - Thanks for the pic. Is that a metal case on the audio jack?

I'd like to play along, but for some reason I cannot access the Spec. or Drawing links, nor can I access the vendors list. I know many on the Inspiron board would be interested in a solution. Is the audio card actually separable from the motherboard, or is it attached by that row of solder contacts in the top-right of the pic?

GM

Yeah there is a metal cover over the whole thing. Here is the pin layout I think I see on the motherboard:



I think the other 5 next to the 2 might be a 6. Its hard to read the board..

Here is another shot of the board:



If this is the right one, I'm gonna go and solider 2 and 6, and 4 and 5.

I am almost 100% sure this is the jack that I have in my Dell 5100 (built in May of 2003).

All the holes are there.. I am just not sure about size and pitch and whatever.. but I think thats it!

I checked the PDF file at FOXCONN, and it surely looks the same as your diagram. (The I8000 series I've been discussing in another thread obviously uses a different part #, I'm sure just to be different!) Soldering the terminals as you mentioned will get you sound from the speakers. Another suggestion: if you don't use the LINE IN (MIC) jack, you can desolder that jack and put it in the LINE OUT place so you can use your headphones and/or speakers! (When you de-solder, it works best to use the de-soldering braid to prevent spraying the liquid solder around. It is available at Radio Shack for about $2)

Best to you all!

Michael

ps If anyone can find a way to order any parts from FOXCONN, please post it.

Thanks for the help everyone.. I am now enjoying music once again, its been 3 months, and I've actually built another computer just to play music! Solidering was the trick, took about 10 minutes to teardown the computer, and put it back together... easy.. For external, I'm going with a USB soundcard, or my IPod to listen to music.
