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:
|Number of Contacts||4|
|Mounting Type||Through Hole|
Here is an extended list of other potential crosses as well: https://www.digikey.com/short/z777pt
The TechForum Cross Reference category is for parts that Digi-Key does not sell or parts that have gone obsolete. 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.
