Default ALPINE MRD-F752 1 BAD TRIPATH TA0102A REPLACEMENT QUESTION

Ok I've got this amp years ago and 1 of the tripath modules is bad and will get the amp in protection mode.If i do remove it from the board amp will power on and work in the front/rear channels with the other 2 tripath's modules left.
I can move one of them to the subwoofer channel and will get audio out as well so I'm thinking other than this bad module i don't have any other issues with the amp.
Model of the module is ta0102a and I'm unable to find one to replace as i want the amp working fully to power on whole car audio system.im finding ta0103a and ta0104a all over are there any options I'm missing

The module may be repairable. Inside, there is a circuit board with SMD components. You may get lucky and one of the drivers or resistors driving the outputs is defective or has a bad solder connection.

The SMD Code Book

Try to match the code. The 1st two characters may be the only significant ones. If you get possible matches, you'll have to match the case. You'll need dial calipers to measure the case to match them.

If there is still a question as to what they are, you'll need to find another one that's identical and check it to determine if it's NPN or PNP.
