Identification of Component T5 on NEXIQ USB-Link 2 (damaged due to crushing)

[Tomylee]

Hi everyone,
I'm currently repairing a NEXIQ USB-Link 2 that was physically damaged due to crushing. After a thorough inspection, it appears that only one component is visibly damaged: the T5 component, located right next to the Mini-USB port.

It's a 4-pin SMD component, with one pin at each corner, aligned front-to-back along the USB port axis. Unfortunately, it is broken, and there are no visible markings left on the part to identify it.

I'm looking for help with the following:

The exact identification or part number of the T5 component

A possible replacement or equivalent part

Understanding its function (protection diode? TVS? regulator? something else?)


NEXIQ refuses to share technical details unless I send in the entire unit for repair, which I'd like to avoid for a simple part replacement.

Thanks in advance to anyone who can help!

This is a choke, you can put two jumpers from thin wire and that's it.

Thank you so much for your help! Your response was really helpful in understanding the component and moving forward with the repair. I truly appreciate the time you took to assist me, have a great day !

By the way, Lotas, how did you know it was just a choke? Did you search for and find documents or anything to come to that conclusion, or did you just know? I’d really like to know, if possible, so I can learn how to solve similar problems in the future. Thanks

The USB input circuit is roughly the same on all devices...
