Default Need a replacement number for the SFE793 Jfet

Hello

Anybody would know a replacement number for the SFE793 ?
It's an obsolete Jfet transistor.

SFE793 (HP number 1855-0020)
N JFET
TO-18
500 mW max
Gm=18mMho at Vds=20V
BVgds=40Vmin
Idss=50mA min 100mA max
Vp/Vgs(th)=10V max
Igss=500pA max

Thank

Bye

Gaetan

2N4856 and 2N4857 from Crystalonics will be perfect substitutes.
