I'am searching a component instead of MAT02

alternative to mat02

HI DEAR FRIENDS,
I need a discerete component or integrated circuit t for a very low level current Ic
on transistor with low noise outputs .Ido not need matching..May I use any transistor?MAT02 is not economic...DATASHEET ENCLOSED:

mat-02 alternative

the mat02 is just a 40v small signal npn pair. use a 3904 or something if you don't need matching. the low noise characteristics of these devices is mostly coming from the high(10mA) collector currents used.

i always thought low current and low noise don't really go together, in fact they are exact opposites in design tradeoff considerations. noise usually follows a resistive trend, and output resistance is lowest at high currents.

mat02 transistor alternative

I need matching...so I look for an alternative to MAT02 or mat 04...
