Replace DC Jack + Power Adapter? Which one?

I have a Medion laptop with the DC Jack shown in the pictures below as well as a power adapter with the following configurations:

DC Output: 19.0V, 4.74A MAX (90W MAX)

Connector size:
- inner diameter: 3mm
- outer diameter: 5mm
- length: 11mm





So my DC Jack came loose and I re-soldered it, which worked temporarily until it became loose again.
Cutting the story short, my current power adapter malfunctioned, so now I am looking to replace both my DC Jack as well as the power adapter.

I was wondering if I could just buy a new DC Jack with some different diameter (inner/outer) and hence be able to use some generic power adapter. Is this remotely possible? If so, does anybody have suggestions as to which DC Jack + Power Adapter I should get as a replacement?

Thanks!

 

They have generic adapters all over, some of them are for specific models others are more universal like what you want with multiple adapters for the power header.

You could also check ebay or something for a used version of a new factory version.

As for the jack piece, radio shack should have something like that.

 

dont go to radio shack, they sell crap.
You need to experience the Mouser difference.
They have every electronics part you can dream of.
Here is a link to their site:

Before you can go replace the port with any jack you want, you need to find the voltage pin out of the current port. Than you will have to find a different jack, which utilizes the same voltage pinouts.
Just find the one your laptop has. There should be some indication numbers on the jack, or on the motherboard. Then look for it in mouser, and then download the pdf. Then look at the pinouts. print the pinout sheet, and then look for another port which uses the same pinout.
You need the right pin out, so that the power supply does not put 12v on the 3.3 volt terminal for your board. Failure to match voltages from the ports will result in the bricking of your laptop.

I would be asking why the DC Jack came loose again. You will only be able to resolder the jack to the board a limited number of times, eventually the board will get pretty messed up (unless you are really careful!)

I would also be asking exactly what is wrong with your current adapter. Maybe it just needs a new DC plug. Cut the old one off, strip off some insulation until you get to nice clean wire, hook up a DMM, plug the adapter in, and see if there's voltage present. If so, just buy a new DC plug and attach to your old adapter.

 

Thanks for the replies. The DC Jack became loose because the connector is L-shaped and it was not properly turned to the site when plugged in, mounting pressure on it and hence on the DC Jack. Don't blame me, it was not me who broke it again

As for the current adapter, there is a green LED on the L-shaped connector which used to light up, but now it doesn't anymore. Hence I presume the adapter to be dead.

But getting back to my original question, so the replacement DC Jack has to match the exact pins that I currently have, but it can have a different inner diameter? The power adapter would have to match the specifications of my current power adapter, right?

Also, re: mouser.com ... is there a specific name for a "DC Jack"?

 

Simply type in "DC power connectors" into the search menu

Then select "DC power Connectors" in the "Interconnects" section
Then simply look for the current jack you have, and then find a suitable replacement.

Their filters work really well, and you can select multiple selections in the same filter section, by holding down the control key.

You want to select "PCB" in the "mounting style" section of the filters.
After this filter has been selected, you will have 137 matches. Then use the voltages, and port size in order to determine which one you have, and a suitable replacement.

I hope you are able to find what you are looking for

Thank you very much, K-TRON. I will try that this weekend

 

You can also use a generic power connector (with enough current rating) and use pieces of wire to connect them to the board, then use glue to hold it still and electrical tape for insulation.
