Dell TB15 TB16 Dock Cable

This Thunderbolt 3 USB-C cable connects Dell TB15 and TB16 docking stations to compatible laptops. It also supports the K16A and K17A docking stations. The metal shell construction protects the connection during daily use. Part numbers 3V37X and 5T73G identify this specific replacement cable.

For Thunderbolt Dock Users

This cable suits owners of Dell TB15 or TB16 docks needing a reliable link to their workstation. It handles data, video and power delivery through a single USB-C connector. Buyers using non-Dell docks or standard USB-C hubs without Thunderbolt 3 support should look elsewhere. The connector type is listed as buffer_79280 in the specifications.

Thunderbolt 3 USB 3.1 Specification

The cable operates under the USB 3.1 standard with Thunderbolt 3 protocol support. This single specification determines whether your dock and laptop combination will function correctly. Verify that both host and dock explicitly list Thunderbolt 3 over USB-C before purchasing. No other interface or protocol is supported by this part.

Questions about this item

How do I install the 3V37X cable and what step do people miss?

Plug the USB Type C Male connector into the Thunderbolt 3 port on the TB15 or TB16 dock and the matching port on the laptop; the step often missed is seating the metal shell fully so the latch clicks.

What maintenance or replacement will the 3V37X cable need later?

The metal shell and Thunderbolt 3 interface are built for repeated mating cycles; inspect the connector pins for debris or bent contacts and replace the cable if the latch no longer holds or signal drops appear.

What limit appears first under sustained use of the 3V37X cable?

The USB 3.1 electrical budget and Thunderbolt 3 signalling set the maximum sustained throughput; the cable itself does not add a lower limit beyond that specification.
