Hello all,
First let me thank the forum in advance for any help provided!
Bit of backround, I am not any kind of trained EE or even a repair guy per say. Just a healty DIY guy with an inquisitive nature. I am good enough at soldering to have repaired several of my home electronics items with success as long as I know to put this thingamajig in that hole and solder it. So what Im saying is I don't understand the how or the why something works but I am decent at following instructions...lol.
Ok, now on my issue. I have a Yamaha RX-Z1 HT Receiver and I really enjoy it. There apparently is a common issue with these that one of the 5 volt IC chips goes bad. It had happened to this one a number of years ago. I found some threads that said which part to replace, ordered one and had a friend put it in. It lasted about a year or so then went out again. It has been sitting for another couple of years in my closet, but now I want to get it back up and running.
I'm better at soldering now than I was way back and want to just do the repair myself. I have taken the unit apart to the area I need to fix. Now the problem is when I went to order the part, it is no longer available and obsolete. Digi key suggested a replacement. I have two questions I am hoping you can help me with.
1) I will link the two data sheets of the components, and if you could tell me if in fact this would be the appropriate replacement. Im pretty sure Digikey has a handle on it, but just want to make sure.

Replacement http://media.digikey.com/pdf/Data Sheets/Sharp PDFs/PQ05RR12,13.pdf
2) Is there something that might be making this part go bad and that should be looked at? I downloaded a service manual and could probably put up the link if anyone needs that.
