2.5mm x 5.5mm x 9.5mm DC Plug
2.5mm x 5.5mm x 9.5mm DC Plug is rated 3.6 out of 5 by 5.
Rated 4 out of 5 by from Worked fine for meI purchased this to serve as a replacement plug for a keyboard power supply. The only issue I had was the cable grip was not adequate to properly clamp around the cable, but I made it work. The final assembled product looked and functioned as well as the original factory connector. That's what I was after.

Rated 2 out of 5 by from Average ConnectorIt's nice that the center contact is solid but would be better if the solder connector was stronger. The length was too short for the jack, though. The proper length plug could not be found on the connector page nor by Parts-Express staff. I finally found the correct plug using the search field but I wasn't about to pay twice.

Rated 4 out of 5 by from Great value DC PlugThis plug mates perfectly with the 090-479 panel jack. Had no problems attaching and soldering wires to the lugs. I was using 22 AWG wire, but looks like 20AWG would work too. 18AWG is too large. There really were no surprises with this connector. I'm not a big fan of the plastic material used to protect the wire and connections, but it's adequate. The project was just recently finished, so I have no experience with quality/reliability for extended usage.

Rated 4 out of 5 by from Works great for notebook power adapterI used this item to repair an Averatec 3200 series notebook power adapter plug that melted and got disfigured. It works great. I just had to trim the end of the plug case a little bit so it plugs in completely to the jack that I also replaced.

2.5mm x 5.5mm x 9.5mm DC Plug

Will this connector work without burning out, on a Parts Express - 12 volt 5 amp power supply ( model # 120-056 ) I have bought for my Lepai - LP-2020A+ T-Amp?

Asked by: Pain for Fun 1980
We don't have maximum current ratings for these plugs, but they will handle the current draw for a Lepai LP-2020 amp without a problem.

I'm going to buy a lepai lp 2020a from PE but it needs a power source. The PE web site says it needs a 2.5 x 5.5 center positive plug. Will part 090-478 work for this application? 

Asked by: Matt11
Yes this will work with that amplifier.
