A1507 PNP switching transistor

Hi,
I need to replace a failed A1507 transistor in a circuit I'm fixing, but
have had no luck tracking down a supplier here in Aus.
Anyone know where one could be sourced, or a suitable equivalent that could
be used in its place?
Thanks for any leads.

Might be a 2SA1507.... The Japs marked them with just a A1507

2 = 2 + 1 pins, S = Silicon A = PNP.

Here's a data sheet on the web
http://www.datasheetcatalog.org/datasheet/sanyo/ds_pdf_e/2SC3902.pdf

Does it fit the package you have?

Yes, that's the one Joe. Any idea where to source it (or an equivalent) from
in Aus?
Thanks.

**WES Components don't have them, so you may need to look for a substitute.
What specs do you need?

** The specs on that BJT are exceptional - he will need the original type.

BTW:

Watch out for TO3P ( as well as TO3) fakes at WES - bought a couple of
Toshiba 2SA1941s that were anything but genuine.

**Tell me about it! I'm starting to lose patience with WES. One of my
colleagues got stuck with fake MOSFETs (for TV repair work). Two different
types too.

More recently, I ordered and received a couple of RCA-RCA leads. Part
#OFC608. They are (or more correctly, WERE) a bloody nice product.
Polyethylene centre conductor insulation, plenty of conductors, aluminium
AND copper braid shielding, nice looking and well bonded to the RCA
connectors. In about 6 years, I've never had a problem with them. I've
installed them into countless customer's systems. They are (or were) FAR
superior to WES's next lower grade product. Although the cheaper product had
fancy looking gold plated connectors and a pretty blue sheath, it was just
bog-standard, crappy RCA cable. Shitty PVC insulation, around double the
capacitance and crappy shielding.

Anyhoo, one of the latest cables developed a fault as soon as I installed
it. Curious, I stripped the cable apart. I found the older, cheaper cable,
with a fancy light blue jacket wrapped around the whole shebang.

I am now attempting to track down all the cables I've sold in recent times.
I'll be sending them back to WES and demanding proper replacements.

** Ha, ha - so YOU got caught with the substitution as well.

The original WES OFC cables were a form of RF coax - 22pF per foot.

Now, they are poorly shielded crap with 220pF per foot.

Are the fakes branded as anything in particular usually or do the use any
manufacturers markings?
Click to expand...

** The fakes are made to look as close as possible to genuine, brand name
devices.


Ever had any bad ST branded TO3s?

** I do try not to buy fakes.

There is no reason why the ST logo would not be used by counterfeiters -
nearly very other famous logo has been.

Thanks Trevor and Phil.
I appreciate you working together to provide me with the useful lead/info.
I think I may need the original (though, through some searching, I might get
away with 2SD600 or 2SA1209 - though I can't locate a source from them
either).

** 2SD600 = NPN, 120V, 1A, 130MHz

2SA1209 = PNP .......

2SA1507 = PNP ......

**As Phil has stated, the fakes are found in most (all?) quality brand
names. The ones I have found usually can be detected by some (very slight)
physical differences. Mind you: those differences are very hard to pick.
Further: The foregoing does not suggest that ALL fakes are physically
distinguishable from the originals.

Star Components have been around for more than ten years. I've dealt
with them in the past. I've even had a visit from their sales rep who
left me several catalogues. They are located in Toongabbie.

I don't know why they don't have an Internet presence, but they supply
AV parts (VCR, TV, CD/DVD, manuals), semiconductors, passives, etc.
They are somewhat like WES in that they cater to the service industry,
but their range is much smaller.
