Source for Dallas/Maxim DS1236AS-5 MicroManager chips

I am looking to source 100 Dallas/Maxim DS1236AS-5 MicroManager chips.
They are obsolete, and while I can find huge numbers available from
various (usually Asian) suppliers via Google, I cannot tell whether the
chips are real or fake. It's also tough to find feedback on these suppliers.

I don't mind which country the components come from, as long as I can be
sure that they are not fake.

Can anyone recommend any legitimate and honest suppliers of obsolete
semiconductors?

Thanks,
Peter

Partminer ceased in 2012 (sold to IHS apparently) and putting your number
into Donberg got no results.

There was another, but I forget the name.

The one that slipped my memory is US Bid.

No matches there either!

For one final batch of 100 pieces of a 15-year-old design. It's a
device used in time and attendance applications.

A new design would be technically preferable, but not financially
viable, given the development costs.

Thanks for your help, Ian. I have a query in with a USA company I found
called 4 Star Electronics, since I found a couple of positive reviews on
them.

All the Asian companies I enquired with claim to have heaps of these
chips available, but they worry me.

I also found a company called IC Electronic Components who sell
"refurbs", which I assume are IC's recovered from circuit boards. They
also worry me!

The only exact match here is "BasicEParts":
http://www.findchips.com/search/DS1236

It shows that they only have 14, but it might be worth asking. They
might be a bit of a worry too though.

Ah, just discovered that clicking on the links goes to "part not
found". Nevermind.

One well known company bought a few hundred thousand microprocessors at a
"good price", after a flood of complaints from customers they found that the
packages were devoid of any silicon.

Organised crime has a simple choice - counterfeiting is a lot less jail time
than drug running.

If you can still find a good archive of the data sheets, it might be worth
studying the part number suffixes. Sometimes its just a minor package detail
that makes no difference to the electrical characteristics.
