Chosen Solution
Hi, I have Sony Vaio svf13n12SGS. I want to replace the power cable. However, I could not find same cable with exactly same numbers. This is what I found : 8pin AWM 20624 80c 60v VW-1 15cm, while, the original cable is: Kotel E220709 8pin AWM 20798 80c 60v VW-1 15cm. Please check the attached photos.
Can I use this cable (the new one) or it must be exactly like the original one? Update (07/31/2019) Hi @jayeff Thank you very much for your help. This is first time I do this type of work and I don’t have any experience. All what I need is determining the right cable. Then I will find a way to replace the cable. Could you please check the attached photo, it shows the width of the original cable.
Hi @shdotcom , I don’t know the answer but I’m thinking that the designers of the laptop choose that particular cable because of its’ specifications, for a reason, especially as it is as you say a power cable. Looking at the specifications for the 2 cables that you mentioned, the original 20798 has a slightly thicker wire gauge than the other cable which means that it has slightly less cable losses. It may be negligible as it is AWG 40 and the other is AWG 42 but in low voltage / high current (for a laptop) situations it may be important. The conductors are also slightly further apart which may have an impact on reducing interference between conductors. I don’t know if this is relevant for where it is. 20624 20798 As you couldn’t find an exact replacement, one option to consider is getting a 9 pin 20798 - example only and use a sharp knife or a razor blade to cut off an outside wire at each end so that the cable fits into the connectors at each end. If you decide to do this be sure to cut off the same wire at each end and only enough so that the cable fits snugly into the connector. I realize that my example is too long at 155mm instead of 150mm but hopefully this will not cause a problem. It seems that some suppliers - example only regard the 20624 and the 20798 as being the same so perhaps the 20624 may be OK. If you have one already try it and see if it causes any performance problems or not.
