The mounting ear holes appear to have the same spacing; the C14 is about 3/4 thick, where the 163 (metal shell) is about 1/2 thickness, so you'd need to enlarge the mounting holes about 1/8 on the top and bottom. Aha, I'm not a fan of non-reversible mods if I've got an alternative. I'm leaning toward the C5/6 connectors at the moment; I see the cables around once in a while, but I'm not sure about the availability of chassis-mount sockets (I expect they're generally PCB-mount). Option 2 is to use a mounting plate with a grommet and simply have a permanently-attached power cable - separate power cables on things are just there to get lost anyway ;-) I'll arrange a trip back to the site where some of the test equipment came from though as there may be a nest of the original cables there - the problem will be finding them, as it was a bit of a dumping ground for ancient tech. Try these: Schurter 0724 series: 4300.0100 - solder terminals 4300.0101 - pcb terminals Schurter 2561 series: 6160.0001 - solder terminals Schurter 2562 series: 6160.0002 - pcb terminals http://www.schurter.com/Components/Connectors/Connectors-Inlets-Outlets http://www.mouser.com/Connectors/Power-Connectors/AC-Power-Entry-Modules/_/N-axiqi/ [I couldn't do much more than a quick search since I'm really busy with flood cleanup.] Keep in mind the C5/C6 couplers are only rated for 2.5A. Something else other list members may find interesting is the Bulgin PX0578/63. Those are a C13 input coupler with 0.25in (6.3mm) quick connect terminals. I'm using some of these to connect power to some really small SeaSonic switch mode PSUs for embedded applications. Both Bulgin and Schurter have all sorts of IEC 60320 connectors/couplers, but the best way to find them is to look at the datasheets and not Mouser's search. Mouser often has the terminations, mounting type, and sometimes even the coupler type listed wrong, so I always use the manufacturer's part number when searching.

Right now, I'm cursing the guy who thought that the cloverleaf or mouseketeer power receptacle was a good idea. I'm sitting here looking at an HP ScanJet wondering if it would be worth the effort to replace it. Fer heaven's sake, what was wrong with the IEC connector? Which specific IEC connector? A lot of people think of the C13 as the only IEC connector, but there is a whole family of IEC 60320 (IEC 320) connectors. If by cloverleaf or mouseketeer you are referring to the C7 or C5 couplers, those types are part of the IEC 60320 standard. https://en.wikipedia.org/wiki/IEC_60320 (Full disclosure: I have access to copies of the official 60320 standards and I spent a good deal of time working with some other editors on the material for Wikipedia). Now, if you want to talk about really weird connectors, Sony had a number of power connectors which can be incredibly hard to find replacements for today...

My modified calculator cable is probably the Japanese calculator type, although it seems to work OK with 163-type sockets despite the mention of the pin diameter of the 163 being a little larger (presumably the receptacles within the plug are pressing up against the pins of the 163 type socket, but not actually fitting over them). I would much rather have the right type, obviously! Big thanks to our own Brent Hilpert for the great reference! Indeed :-) Jules

If you mean the one that a mad friend of mine calls the 'figure of 12' (on the grounds that the 2 pin one used on radios, etc, is often called a 'figure of 8') then I believe it _is_ an IEC connector, in the same standard as the more familiar 'kettle plug'. The thing that annoys me about this connector is that a rewireable cable socket does not seem to exist. Just moulded cables, which I dislike on the grounds I can't check that the wires are properly connected (and not just held on one strand). A rewireable 'figure of 8' does exist, but the version I have seen doesn't have a proper cable clamp. -tony
