View Full Version : OT- Odd Replacement Cord

I have an old piece of equipment that has an odd power cord. It doesn't show in the picture, but it is a bit chewed up and should be replaced. So far I have not found anything like it on the internet. I would assume I have just not found the correct wording yet. None of the industrial sources have anything that look like it either. Has anyone seen one like this before and have a name for it?

If I can't find something I have no problem with taking it apart and retrofitting it with something standard like an IEC cord.

I have some piece with the same connector. Dont know what they are called though. Basically the predecessor to the common IEC power cord. Go to goodwill or the like and dig, you might find one.

There are numbers on the end of that cord. I can't quite make them out. If you google them you might find a replacement.

7A 125V and M3

The M3 did not turn up much.

Well, I'm out of ideas. Any identifying marks inside the receptacle?

Often time the schematic has connector types and names, is one glued inside the case?

It sure looks very similar to the plugs that provide power and plug into a computer and the monitor. Its kinda hard to tell the size though. Jan

Hewlett Packard and Wavetek were big users of that connector on their electronic test equipment at one time. I do not know the designation for them, we just called them 'round pin HP cords'. They seem very rare so were probably not used much elsewhere. I have seem them for sale somewhere (I believe E-bay) but they were something over $20.00.

Looks like you have an old HP power cord. That is a very common style of power connector on older test equipment. It has been replaced by the IEC 60320 C13 and C14 connectors. They are hard to get now as they probably aren't made any more. Nobody uses the connectors for new equipment, so people don't make the connectors.

These folks still have a few:

Other than that, you can scavange them from old equipment. Or retrofit a C14.

Check out the '17952' power cord a little more than half-way down this page. It also says "Belden-Volex', 'made in Mexico', and 'Tram D201'. Hope this helps.

Those are certainly the right ones.

At just under $20 it is an easy choice.

Thanks all!

Unless you just want to preserve the look of the equipment, for $5 to $10 you can get a "D pin" replacement connector for the chassis. Then any standard cord would fit.

From others info I found the following:


"The round-pin power cords used on older Hewlett-Packard and Dolby equipment¬ uses a connector called the PH-163.¬

The round-pin power cords using the PH-163 connector come in two versions. The difference between the two versions is that the hot and neutral are reversed. The ground is always in the same centre position.

Volex power cord model #17280 has standard polarity per UL 817 and CSA 895B.

Volex power cord model #17952 has¬ neutral and hot lines reversed.

There is only a risk for maintenance operations. There is no user risk under most applications.

In viewing the PH-163 connector from the end so that the centre earth contact is above the other two, then the neutral is on the left and the hot or line is on the right in the standard #17280 cord set.

In viewing the PH-163 connector from the end so that the centre earth contact is above the other two, then the neutral is on the¬ right and the hot or line is on the¬ left in the reversed #17952 cord set."

Thanks for pointing out that important distinction. I'll check to see what I have now versus what I replace it with.
