All semiconductors have a code number for the case. A 2N3055 for example is a "TO-3" case. A BC109 is a TO-18. 2N3094 etc. are TO-92. But watch out!...TO-92 comes in a wide variety of suffixes- TO-92a, TO-92b etc. This means that the component has the same physical "footprint", but the electrical pinout to the device is different. The best thing to do is Google the part # you are looking for followed by "pdf". This will hunt down the datasheets for the device. Check out the pinout (usually on the first page) and a handy table should make you aware of any different pinouts.
In a PCB package, when you define a device package, the software will just place a "TO-92" pad. If you're drawing it by hand, it's then up to you to work out the pinout!
But, if you have schematic>PCB software, you will have to define the actual device number including suffix, so the autorouter knows how to connect the package.
BTW, are you designing a 1176 board from scratch? Have you re-designed the actual circuitry? It just seems a rather large project to begin PCB layout on
Good luck with it!
