General Question

I am wondering, is it possible to use a 5.5 x 2.1 mm male plug inside a 5.5 x 2.5 mm jack for transferring 12 Vdc?

My thoughts are just that it may just be a tight fit on the inner conductor. It may also just not fit. I figured before spending money and waiting a few days to try it out, it was worth asking here.

My Use Case

I have an Intel NUC, which can be powered off 12 Vdc via a 5.5 mm x 2.5 mm jack:

The back panel DC connector is compatible with a 5.5 mm/OD (outer diameter)
and 2.5 mm/ID (inner diameter) plug, where the inner contact is +12-19 (±10%) V DC and the
shell is GND.

Source

And it seems the 5.5 x 2.1 mm plugs are much more common, so I would like to use that.

  Without more specific information about the mechanical arrangement of the plug and jack, as well as their nominal dimensions and tolerances, I don't think anyone can give a better answer than the one you provided yourself: maybe, maybe not.

  In a 5.5x2.1 plug, 2.1mm is a hole diameter. Forcing a 2.5 dia centre pin into it .... no. Other way round you get a sloppy fit and unreliable contact.

This must be evaluated on a case by case basis, as sometimes the spring loaded tabs will allow for a few 0.1mm's of play. However, 0.4mm is most likely too far and a the right jackplug combination with less than 0.4mm between the barrel and outer diameter of the plug needs to be found.

Whenever I do product testing with jacksplugs, I usually buy several options and make sure that customers (boss, product development team) are happy with the plugjack combination before I build a prototype.

I have tried fitting a 2.1 mm barrel plug in a 2.5 mm jack (by accident or consciously) many times and it has never fit. Both sides are rigid and there is not enough clearance.

Size adapters are available; I recommend having some around for use when you have a device that doesn't come with a power adapter and an adapter with the right voltage. They do have the disadvantage of making the plug longer, hence more awkward and vulnerable to damage.
