Different Between Component

There we have different between  from a same component that take from the magazine and after the component buy at store of 'Jalan Pasar'. The component is transistor (in circuit TR1). Transistor's serial number from magazine is TIPP31C npn and after buy they give transistor that have serial number give is TIP31C. The problem is, that both of transistor is the same component or other type of transistor?
