DC JACK Power jack fits the below consoles.
These aging consoles really benefit from a brand new dc power jack. 
Old power jacks are often rusty, cracked, and the leaf is weak causing poor contact. 
Its highly recommended to replace that old worn DC jack with a brand new unit for the most reliable power connection. 
 
Soldering required. 
This DC Jack is intended for the following consoles.
 
TG-CD-DOCK
ATARI 5200
PCE-IFU30
TWIN-FAMICOM
NT MINI NOIR
 
Two Jack Atari 5200.
The pin configuation on the Atari 5200 is flipped so you would need to modify the install to work on  Two-Jack Atari 5200. The side pin is on the opposite side. To install this jack on the Atari 5200, (depending on the 5200 version) you may need to bend the side pin outward and run a jumper around from the side pin to the contact-hole on the opposite side. Hot Glue can be used for extra mounting stability if desired.
