replacing DMP8 with SOIC or DIP

Hi everyone,
 
I have not seen an answer to this before. Has anyone tried to replace a DMP8 part with either a SOIC8 or DIP8 part before? If so can you share your experience? I have not been able to find any adapters for DMP parts and eyeballing them the DMP part is smaller then a DIP and larger then a SOIC. Any help would be great. 

Thank you

I haven't really searched, but the only adapters I've seen are for using a surface mount chip in a DIP  board...  So that you can use a SMT part in with traditional prototyping techniques.

Are you trying to repair something, or modify something?

If you're trying to repair something and you can't get the original part, you might be able to get a replacement board.  If you are trying to modify something, it's probably not worth the trouble.* 

If you feel it's worth the effort, you might be able to rebuild the entire circuit (or sub-circuit) on some sort of prototyping board.



*  i.e. Op-amp upgrades are usually "audiophile nonsense", unless there is a particular spec that needs improvement.  And in a properly designed circuit, op-amp variations have very little effect on specs/performance.  The exception might be noise in a high-gain (microphone or phono) preamp.

Thank you DVDdoug,

I am trying to replace these parts with upgraded ones. I want to see for myself if it will sound better.

If there's something wrong with the sound, the odds are that something else is causing the problem and replacing the chip won't help.  And if there's nothing wrong with the sound, there's nothing to improve. 

If it was a DIP part in a socket, I'd say "go for it"...  Or if it was a soldered-in DIP, you could add a socket. 

If you just want "better sound", I suggest you get better speakers (or headphones), or simply adjust the EQ.   

Is this thing you are working on "disposable'?    Are you going to feel bad if you distroy it?  There is always a risk when you start soldering, and replacing the part with one that doesn't fit properly increases the risk of permanent damage.    Personally, I don't do any surface mount soldering at home.  We do have a surface-mount rework station where I work, but there is a limit to what we can do and if we have to replace any fine-pitch components, we send the work out to our PCB assembly contractor.
