No. of Phase : 4
Step Angle : 7.5°
Coil Resistance : 100 Ohm ± 7% / Phase
Coil Inductance : 59.1mH ±20 / Phase
Step per Revolution : 48
Current : 0.24A / Phase
Holding Torque : >800g.cm
Pull-in Rate : 340pps MIN
Pull-in Torque : 270g.cm at 100pps
Insulation Resistance: 100MΩ MIN at 500VD
Detent Torque : <210g.cm
Rotor Inertia : <9.6g.cm
Stepping Accuracy : 7.5° ± 7 %
Life : 3000h MIN at 20℃
Weight : 136g

Phase 1 : Brown
Phase 2 : Black
Phase 3 : Yellow

I don't know of anything like that offhand. You will probably need some more detail regarding dimensions, mounting hole locations # shaft size. Some useful search terms that might get you closer are:

"unipolar 48-step motor"

That yields plenty of hits - mostly on ebay. Unfortunately, most do not have detailed specifications.

How close to the specs to things need to be?

By the way, I think the part number is PM4222-09.

That does turn up some more promising leads. This one looks like it would work:
