content: Does anyone who if one can buy a DC jack receptacle for through hole soldering on to a PCB which has a 2.1mm pin in a 5.5mm DC barrel jack, and is vertical entry (the male barrel plug power lead would point stright down towards the board). Plus the pins need to be the same sort of pins as found on a typical 2.54mm header, two such pins with a 2.54mm pitch between them. The intention being that this DC jack can replace a two pin header and go in to the very same holes on a board as the header used to, the vertical entry being necessary due to other parts on the board blocking right angle entry access to the place where these two header pin holes are.I'm trying to swap out some inconvenient header pins and wiring on an existing board for a quick to connect and idsconnect DC jack which would be compatible with DC supplies I already have to hand. That's why it is really crucial this can fit in to normal header holes rather than have those big rounded tabs with holes in them which need large milled slot through holes to connect to (absolute menace of a default design as it makes the DC connectors impossible to use on things like stripboards with re-drileld holes).Does anywhere (which is easy to buy from for UK buyers) sell them?I've found some vertical entry DC jacks but all of them still have the tab type "pins".Thanks

content: Never seen ones, and I searched hard many times. Yes there are vertical jacks (there's plenty of them on aliexpress), but all of them have flat pins (tabs?), spaced at some weird pitch, not matching even a multiple of 2.54 mm, let alone having exactly 2.54 mm between the pins. They are all 3-pin, too.I always got away with drilling the (prototyping perforated type) boards as required for those jacks. Maybe you can try to bend the tabs as required, put some wires into the holes on the PCB and solder the jack tabs to the wires and wires to the PCB. Remove the third pin.

content: Have you looked at switchcraft's site? They seem to have the widest selection of (quality) DC power jacks.I've usually found what I need.www.switchcraft.com/catalog/jacks-and-plugs/dc-power-jack-and-plug-series/

content: CUI Deviceshas some interesting DC jacks with pins "panel mount" but most all have big tabs for mechanical strength and current handling.

content: How much space have you got?Is making up a little board an option? One that takes the tabs for the socket and has the header pinsLikethisbut for the socket style you want, and probably a bit more compactly laid out.

content: Those large tabs are there to support the jack for repeated plugging and unplugging. Best bet is what SmallCog suggested . Arduino DC power plate.I've not dealt with this particular distributor, but being in the UK you may have more information.https://kunkune.co.uk/shop/accessories/dc-power-supply-module-for-dc-power-adapter-plate/Other sources are Amazon and Aliexpress.

content: Thanks.It does seem that one can't be found acording to my specs as an existing component.I'll go ahead and design a little adapter board to go from a typical horrible 3 tab pinout of a typical jack to a 2 pin header pin style connection with a right angle header. That will fit my requirements.

content: Why build an adapter board? Can you not find an appropriate panel-mount female barrel jack? Just get one of those and connect a short tail from it to some other connector that you can plug into your existing header.
