You can easily wind your own. 500turns on the bobbin of an 1811
potcore with AsubL of 2300 gets you very close.

Impedance of an inductor is a direct function of the frequency, 
Zsubl = 2*pi*f*L

But five 100mH in series WILL work.

They are more expensive than simulating them electronically or doing
the same thing another way.
