TG-A6050-24-21.01-1.0 is a thermal pad from from t-Global Technology, which we will no longer carry once current stock runs out.
I did some looking to see if we have a good replacement option, and here’s what I found. The best alternative we have in stock is part number 1168-TG-A6200-24-21.01-1.0-ND. This is a good match for the thermal conductivity, adhesive, and size of the original pad, which I would consider the critical specifications for most use cases.
It is not a direct cross-reference however, so please review the datasheet before using this as a replacement: TG-A6200_UK.pdf
