So, here is the one that I know works in a circuit, but I'm going to have to add another winding, and I know it won't fit with the 22gauge wire I have.

Datasheet.

But, I thought maybe I could increase the size and it would help to get it rapped, but I don't know how to calculate for the increased size, the characteristics are different enough, that I'm not willing to guess.

Can anyone help me find the correct replacement?

Datasheet on a possible replacement that I found.

Thanks for any help, in advance.
