Cross referencing NTE part number to industry parts?

[MRW]

Hi all,

I was curious as to how I can do a backwards crossreferencing using NTE
part numbers to get original industry part numbers. At the NTE
(www.nteinc.com) website, I can only type in the existing industry part
number and get a replacement NTE part. I would like to do this search
in a reverse way.

I have an NTE part number (NTE723), but I don't know the part that it
replaces, so I can find out the original datasheet for it. The NTE data
sheet seem to be a bit vague at times.

Thanks!

That can't be done. If the NTE part has higher rated voltages than the replacement, then
there is no direct replacement. Perhaps some can enlighten on some of the mysteries
of NTE part. I'm sure there are stories to be told.

I worked at a store that sold NTE, we had a reverse sheet. ask your
local dealer.

NTE does everything in their power to prevent you from doing just this.
Your best bet for finding the replacement may be to feed phrases from the
datasheet into google and see if it finds anything.

Years ago there were a few web sites that listed the crosses but they
didn't show up in a google search.

Try looking up the National and Motorola chip with the same function. You
may get lucky.

You are best off to never design a NTE part in. Even though their parts
are copies of other makers parts you end up single sourced as you have
discovered. Also, I have found that their parts (RF transistors) are not
all that good of copies and tend to have a higher failure rate than the
part they copied.

With that number try HA LA or LM series ICs.
ECG used to tell me what part they actually used.
NTE might tell you what parts that will replace one of which will be
the one they buy.

You get out your 25 year old EGC databook, which are just reprints of
the manufacturer's datasheets with the manufacturer's logos removed and
see if you can recognize the style of the schematics, and then you take
your ECG or NTE cross reference book and look under the part numbers
for that manufacturer.

RCA CA3075 FM IF amplifier/detector

Next time, ask in sci.electronics.components

An Industry part that is the saem as the NTE723 is MC1375P so you can dig
up the data sheet for this part to find details.

No, I did not find a cross reference list, I just got lucky on a google
search......

Thanks, ya'll! I found out that there is a local NTE distributor here,
so next time I'm stuck with an NTE part, I"ll just give them a call.
However, I might stay away from NTE parts in future projects after
hearing a few comments about their reliability.
