I think it's just an older version of the same motor.
I've bought several 8735 Advanced Power Packs from different sources.
The newer ones had the 71427-002 motor and three that I got from a local toy
shop had obviously been sitting on their shelf for about 3 years and they had
the 71427 motor.
Incidentally, the three old ones were all faulty (jammed or very stiff), so I
called LEGO Service and they replaced them FOC with new motors (71427-002).
I'm pretty sure it's safe to use with the RCX, although you might want to see
if the older motor feels at all stiff compared to the newer one. If you spin
the shaft by hand it should keep spinning for a while on its own.
If it's not right, give LEGO Service a call.

| Greetings! Recently I picked up a lego techo kit (#8266/3038) to add some extra parts to my collection.
