Need help locating transformer
 
I waited a little to long to start a project and it seems the transformers that I need are no longer available. The one I had intended to use are here 030-7330-0 Pulse Transformers Audio & Signal
I have spent the last couple of hours trying to find something as a suitable replacement and have come up empty handed. If anyone can point me to something close I would appreciate it. It does not have to be pcb mount like the one shown. I can wire it to the board easy enough. I just need a transformer that will work. Thanks, Bryant

What are the criteria for "suitable"? The Hammond 164E12 (see < http://www.hammondmfg.com/pdf/5C008-9.pdf >) meets the basic electrical criteria, but the mechanical details are different.

There may be other possibilities at < http://www.mouser.com/Power/Transfor...yzutlbZ1yzuxsv >

I'm not to concerned with it being the same type that mounts on the pcb. As long as it has 12v/200mA capacity it should work. I'm now thinking a Hammond 266EA24 would work as a replacement for the two 12v that I was originally looking for. I could jut mount it to the case and run the leads to the pcb.

Have a look at Farnell. They might have the one you need.

If you are really stuck to the pin layout, then it will be not so easy.

If it for the PSU then surely any 12V >200mA transformer will do the job.

I don't wish to insult your intelligence, but, are you aware that any transformer that will produce 12V at more than 200mA will do the job ?

Just because you fit a 1A 12V transformer does not mean that the transformer will deliver excess current.

No offense taken. It helps to be reminded of the rules of electronics from time to time.

I know I could put as big a 12v in there and the circuit is only going to draw what it needs. I was just looking for something close to what was called for. Like you said anything >200mA will do the job just fine.
