Hi. The BA662A is pretty rare nowadays… You may be better off using the (almost) identical BA6110. It is a bit quieter but very similar otherwise. There are loads of BA6110’s on ebay.

This website has a good description of the differences:

What it doesn’t mention is that two of the pins are swapped so a slight mod would be needed to the board, I can’t remember which ones but the datasheets should tell you.

Hi Phil,

i have already read it and it’s very interesting but it’s not for make a clone but to replace defect part into my old gear and that’s why i’m looking for BA662A and not BA6110.

Thanks.
