154-UBS21-E is a USB B connector that I recently crossed and think we have some good alternates for. Here are the following specifications on the part I used for finding a cross:
| Specification Name | Value |
|---|---|
| Connector Type | USB-B |
| Current Rating | 1.5A |
| Number of Contacts | 4 |
| Mounting Feature | Vertical |
| Mounting Type | Through Hole |
Simply based on price first, the part number I first chose is Digi-Key part number 2057-USB-B-S-VT-ND; manufacturer’s part number USB-B-S-VT.
Here is an extended list of other potential crosses as well: https://www.digikey.com/short/z777pt

Our Engineers and Techs have reviewed the specifications for these parts and made a recommendation for a replacement. Please review the suggested part to ensure it will work for your application.
