Your lucky you can use it. Scrapping it was a real kick in the teeth. I'd rather it just disappeared than waste the time turning it into 10 carbonite circuit boards... 10 Carbonite circuit boards for a cashed in LST!!!!
As the others have said, they don't mix and match well in other teams. However, depending on your ranking. Nass, Phalanx and one other in 3v3 'might' work on defence in the very low leagues. I remember when the team first came out, players were doing this and....it was a bit troublesome, until we worked out that you can ignore the shield generator without Jar Jar. However, in low carbonite, people might not realise that.
