Depends on the device and manufacturer, they usually have a code appended to the end of the part # to indicate how leads are formed. Check the spec sheet.
Just use a device in a TO92 package the easiest way to apply in your circuit. No matter what the pin arrangement is you can bend the pins suiting your needs.
I even use them with double pin spacing if I have to throw a trace between pins to keep the PCB layout single layered.
Never bend the pins directly at the plastic body. They might break. Use watch maker's plyers or a strong tweezer to bend the pins.
