Default TBA810SH amplifier equivalent

Evening
A question, I have a dead channel in a boom box radio, it looks as if one of the output ICs has gone. It is a TBA810SH these are available, but I’ve seen some TBA810P at a cheaper price. Does anyone know if they are the same item/spec please.
Thanks

I think they are electrically the same. But the SH has staggered legs as opposed to DIL I may be wrong though- so double check. There are plenty of data sheets online. You can modify the legs to fit from memory.

Thanks, I've looked at some data sheets they both look the same with staggered legs, so wasn't sure if I was missing something or they are the same?

The only difference I can see is that the P suffix device has a built in clamping diode on the output. The datasheet also says that the p suffix device is an improvement of the s device, maybe that is the improvement.

From what I remember (and it is from a long time ago) the ..SH has holes in the heatsink tabs for bolting to a heatsink, and the ...S doesn't, having tabs for soldering to the board. I may well be wrong though.

The AS has the heatsink tabs and the SH has the large solder tabs.

If the suspect IC in Robsradio's set is bolted to an additional heatsink then it does sound as though it's going to need a like for like replacement, the SH variant. If the heatsinking tabs aren't bolted or soldered to anything then maybe the 'P' version will do.

Thanks gents, I will have to get deeper into it and see how the heat sinking is attached. Cheers for your help.
