It depends on its purpose in the network, the change in requirements for that purpose over time,  and the vendor's support of the device.

A router handing 10Meg of traffic between offices might last until the vendor abandons all support of the unit. A router in a segment where traffic rates are changing rapidly might need replacement sooner.  Sometimes it is the introduction of some new technology that drives a change in equipment if the new feature provides some overall benefit.

No set in stone replacement cycle.
