I am looking to replace the following AC/DC wall wart:

Bothhand Enterprises Inc
Model M1-10S05
AC Input 120VAC
Output: 5 VDC 2.0 AMPS

I am not interested in paying Radio Shack $22.00 for the privilege of replacing a$3.00 item. Or several other places for $15+ plus s/h. If possible I would like to replace with same item, but will consider equivalents. OEM is wholesale only, as are many of its dealers." Sure how many 1000 do you want? 1, SINGLE, ONE. Sorry, min. 1 shipful." Any useful suggestions (minus Google & Froogle) on sources for replacements welcomed. Thank you in advance. M #### Mike S.

If it isn't on their website, ask for their printed catalog. There are 9
pages (small print) of wall wart and tabletop power supplies in the
current edition.

I think you're overly optimistic on the price.

Run of the mill, and cheap, tend to be low current. Once you get up to 1amp,
I'd say the price rises. And by 2amps, they are less common so the price goes
up even further.

Given that this is a 5vdc adaptor, it's also not likely to be run of the mill.
The voltage suggests it runs logic devices, and hence needs that 5v to be
regulated, which will add to the cost. The cheap adaptors don't regulate,
and so use less circuitry.

BC Micro has a 5V 2A wall wart for $3.99 with 1.6mm plug. See it at http://www.bgmicro.com/pdf/page13.pdf . I don't know about their minimum purchase or handling charge, but it might be worth it for you to have a look. M #### Michael A. Covington Jan 1, 1970 0 Mike S. said: Regulated or unregulated? From the current rating (2.0 A), it sounds like a regulated switcher. This is not a$3 item. This one should cost $20-$40 in single quantities.

I'm not sure he realized that this is not like the cheap wall warts (like 9
V unregulated 300 mA) that we so often see.

The fact that one can apparently can get them at surplus outlets does not mean$20 or whatever is
overpriced.

I've bought plenty of simple switching supplies at the local surplus
outlet for a couple of dollars each, but that doesn't mean I can expect
to get them everywhere for such a low price.

Michael Well I think you miss the point. The reason you can get them so easily surplus is that in quantities of about 500 they are$2.56 from at least six different
suppliers. But if you want only a few. The surplus house is the better deal
since the manufactured have a minimum billing or sell samples for $20 to$50.
The fair price if you want a custom, but common, the surplus is a deal!

Of course not. But for the OP's one-off, it's probably the best deal he can get. That who the post was addressed to.

:The voltage suggests it runs logic devices,
:and hence needs that 5v to be regulated
: Michael Black

Before I hooked a cheap unit to anything critical,
I'd check its output open-circuit and full-load (2.5 ohm 10W resistor).
If it's outside the 4.75V - 5.25V spec for TTL, I'd reconsider.

Even if the cheapie won't do this job, you're not out much $, and you can keep it for other stuff or re-sell it.

I won't say that I've bought hundreds of wall warts from these supplies, but
it does run into several dozen with a variety of specifications and there's
been no bad ones (yet). I doubt that they check each unit and I assume that
each one has gone through whatever it's manufacturer deems an appropriate
quality control procedure, but I do look at every one with a scope to see if
the output looks reasonable and I do meter the voltage. I think I'd do this
if I bought them from Jameco or Digikey too. And many of these are "name"
brand units that were surplus, not just cheap knock-offs.
