Hi,
Don’t know the answer but the usual size is either 2.5mm/5.5mm or 2.1mm/5.5mm plug and socket.
The sizing refers to the diameter of the centre pin connector (2.1mm or 2.5mm) and the overall diameter of the plug and socket (5.5mm).
It is very hard to visually spot the 0.4mm difference when just looking at centre pin connector of the plug or socket.
A way to know what size you have is if you have a known 2.5mm plug (the more common size) is that it will fit into a 2.1mm socket but it will be a loose connection and may not be connected all the time i.e. intermittent power problems can result. The 2.5mm centre pin of the plug fits over the 2.1mm centre pin connector in the socket
A 2.1mm plug will not fit into a 2.5mm socket. The 2.1mm centre pin of the plug will not fit over the 2.5mm centre connector of the socket.
The outside diameter of both is the same at 5.5mm.
Hopefully this may help in finding a suitable replacement plug or socket
