    What is the manufacturer's ID/code/label for that part? RS doesn't even seem to list it as obsolete.

    That's the problem, RS don't even list it. It is a 12Vdc 58 ohm relay, the only other marking is the RS number

    OK, a 12V relay, what is the configuration of the contacts and what load are you switching (or want it to be capable of switching)?

    Do you need a plug-compatible relay (to fit into an existing PCB for example)? or just something similar?

    Some photos may be useful.

    I found a reference by RS here. It is marked as discontinued, but you could ask RS ´whether they can offer a substitute.

    RS 348 447

    I have been told by the RS tech guys that it was declared as obsolete in 1997, they have given a tech spec for another one but the mounting doesn't match.

    Give us the technical specs, including the pin layout. (I wish you'd told us you had that)

    Not Relay, Solenoid.

    That really looks like a solenoid to me, maybe the S in RS stands for Solenoid
    could be a combo---RELAY/SOLENOID...

    like do a search for solenoids.;)

    RS stands for Radio Spares -- the name of the company.
