You must always confirm from a second source when you back trace the NTE tables.It's big trouble if you don't.
The Fairchild MPSA06 is an 80V transistor. As you claim, 1103ca is 75V.
(EDIT: And you assume that the house number 1103ca is actually a 'famous' generic number that I cannot validate on the net.)
This is not the fault of All Electronics. You should only use your NTE book for the purpose that it was intended.
You have no proof.All Electronics labeled the package as containing the transistors: MPSA06
They were NOT.
Like mneary has tried to explain. You/one can only trust an NTE catalog if you use the (overpriced) suggested NTE part (maybe not even thenbtcg said:As AE will do, it lists the part number as being essentially the same: MPSA06 <snip>So I popped open my trusty (even if it's 14 years old) NTE crossbook and crossed it.
To my surprise, the transistor crossed to an NTE 287: a 300v transistor.
In addition, nor does it mean that the MPSA06 is interchangeable with the illusive 1103CAmneary said:NTE is free to supply a 300V transistor to replace either one of them, but that does NOT obligate all makers of MPSA06 and 1103ca to convert their lines to 300V.
There's that word 'trust' again in reference to a NTE book. You cannot use the NTE book to compare two different components.btcg said:<snip>Lo & behold, the number on transistors is different: 1103ca.
Again, refering to my trusty cross book, I look up the 1103 (from experience I knew, it's actually 2n1103), and find that this transistor is actually equivilient to the NTE 123ap, a 75 v transistor (a famous one, at that)
75v vs 300v: a pretty big difference.
If you use a NTE book the way your implying, then you will have a lot of smoke over time.btcg said:But had a friend brought over an old tv with a video problem, using that transistor might have ended up in smoke.
Why don't you contact the supplier and ask them to fix it and give you the MPSA06 that you ordered? Peoples do make mistakes. Hard to believe eh?btcg said:The lesson here: beware of these surplus vendors, and always verify their cross-referencing.
It isn't likely a mistake. The supplier clearly stated what was for sale, and they show a clear photograph of a TO-92 marked 1103ca. They say 1103ca is a house number for MPSA06, and I say adding 2N in front of a house number doesn't make it a wimpy obsolete TO-5 transistor.Why don't you contact the supplier and ask them to fix it and give you the MPSA06 that you ordered?

It all makes sense now. He didn't order a mpsa06 an get a MPSA06-HM, like he implied, he ordered a 1103ca disguised as one.bctg said:One of the packages was a pack of 10 npn transistors I'd ordered from All Electronics (allelectronics.com), Catalog # MPSA06-HM
As AE will do, it lists the part number as being essentially the same: MPSA06
Thanks for the clarification. I didn't think about going to that website. I wish I had:
You are correct. There is probably no way that those are the archaic 2n equivalent.
Maybe they are just what they say they are. Nevertheless, he got exactly what he ordered.
bctg, if you had linked to your purchase like this, things would have been so much clearer.

And no bctg, my english is just fine.
cheers
If you believe your own eyes, you'll see that a real 2n1103 comes in a TO5 case and NOT a TO92 case:Given AE's track record, and my own semiconductor experience, I believe my own eyes: it's not "house marked." It's a real 2n1103.
What you received was in a TO92 case, right?/www.allelectronics.com said:MPSA06 transistor. Small NPN power and signal transistor. TO92 plastic package. This is a "house-marked" part, stamped 1103CA. Taped, ammo-pack packaging. 10 piece minimum.
If you believe your own eyes, you'll see that a real 2n1103 comes in a TO5 case and NOT a TO92 case:
What you received was in a TO92 case, right?

What makes you think that **broken link removed** is a Japanese company? Japanese transistors usually start with 2SA, 2SB, 2SC, 2SD, etc.
Why don't YOU post a datasheet showing the 2N1103 in a TO92 case? Your arguments will carry more weight then.
I know this.For reference: all 2sa's & 2sb's are PNP
All 2sc & 2sd'd are NPN
What do you mean by also? Are you claiming that National Semiconductor produced the 2S series?But National Semiconductor also was responsible for the 1n (diode) and 2n(transistor) line. Look it up.
I have nothing to prove. You do.Excuse me, who is questioning me? Isn't it you?
Post the correct datasheet(and ALL of them)
Dollars to doughnuts, the Japs produced an 2n1103 in a To-92
Yes, I made some transcription errors from the initial post to my first response, which scrambled my logical process. I regret those errors which prolonged this discussion.NOW: I think mcneary was right, but inaccurate.
