I expect you mean TL071. The other is a dual, and the pinout is quite  
different.

As long as the pinouts are the same, most op-amps are very forgiving.  
You can mostly swap op-amps for a "better" one (lower noise, lower  
power consumption, whatever) without any problems. Obviously there  
are a few rare circuits where a particular part is critical, but I've  
never seen one.
