Looking for connector ideas to carry USB + 24V (3A)

[guscrown]

Hey guys,

I'm looking for a possible replacement for this FCI connector: https://www.digikey.com/products/en?keywords=74355-1042 which is part of the Powered USB family.

So far it's been pretty good, but it has become more difficult to source, and lead times are pretty long, and considering that only FCI makes it, we are pretty much stuck.

I'm looking for an alternative that I could use to replace it. This is for a printer in a POS system. Printer is a USB device, and it requires 24V with a max current consumption when printing of 3A.

Any ideas?

In a pinch, D-sub can be used for USB 1.1. Alternately, you can abuse an RJ45 or a 10 position RJ50.

The device is a USB 2.0 unfortunately, however the 10 position RJ50 doesn't sound that bad. What would be the best way to distribute the cores?

24V: 3 cores
Gnd: 3 cores

D+/D-: - 2 cores
VBUS : 1 core
USB_GND: 1 core

D+/D- should be close to each other (using a twisted pair). Do you really need a separate USB_GND?
