Product Overview
KEC 2SA562-Y Silicon PNP Epitaxial Transistor, Marked A562 Y
Condition
New and unused. The photographs show a black molded plastic three-lead package in the TO-92 style, with the flat face marked in three lines: the block letter K of KEC followed by the code 8E on the top line, A562 on the second line, and the gain rank letter Y on the third. The leads are full length, straight, untrimmed and unbent, bright and free of solder, flux, or board residue. The case is clean, with no scratches, chips, or heat discoloration, and the marking ink is crisp and fully legible. Stock on hand is 8 pieces.

Product Overview
The KEC 2SA562-Y is a silicon PNP epitaxial transistor intended for audio frequency low power amplifier applications. The block letter K on the top line of the case is the maker's mark of KEC, Korea Electronics Corporation. The body is marked A562 rather than 2SA562, which is normal for JIS-numbered small signal devices: the 2S prefix is dropped at the package, so A562 on the case and 2SA562 in a service manual are the same part. The trailing Y is the hFE classification rank, which narrows the current gain to one band inside the family instead of the full spread. In the photographs the part is a three-lead through hole device in a TO-92 style molded case, the standard small signal package for driver, preamp, and low level audio stages. Collector voltage, collector current, the hFE range for the Y rank, and the pin order are not confirmed here - verify them against the 2SA562 datasheet before use.

Applications
- Audio tech going through a 1970s or 1980s Japanese receiver who wants the marked original back in a preamp or driver stage instead of a modern substitute.
- Cassette deck and tape machine repair where the board silkscreen calls out a 2SA562 and the service manual specifies the Y gain rank.
- Bench builder prototyping a low power audio stage who needs a through hole PNP small signal device with legible factory markings.
- Collector or restorer keeping a small drawer of period-correct JIS-numbered small signal transistors ahead of the next repair.
Frequently Asked Questions
Is A562 the same thing as 2SA562?
Yes. JIS-numbered small signal devices are marked without the 2S prefix, so the A562 you see on the case is the 2SA562 your schematic or service manual names. The letter on the line below it belongs to the part number as well, which makes the full designation 2SA562-Y.
What do the K, the Y, and the 8E on the body mean?
The block letter K at the head of the top line is KEC's maker's mark - Korea Electronics Corporation built this part. The Y is the hFE classification rank, which sorts otherwise identical devices into current gain bands. The 8E sitting next to the K is a factory code. We are not going to guess at it as a date - treat it as a lot marking unless you can confirm it against KEC's own coding scheme.
Which specifications can you actually confirm?
Only what the part itself and our own records state: KEC manufacture, silicon PNP epitaxial construction, the A562 Y marking, and audio frequency low power amplifier applications. Collector to emitter voltage, collector current, the hFE range for the Y rank, and the pin order are not confirmed here. Pull the 2SA562 datasheet and verify them before this part goes into a board.
I need two or three for one board. Do I have to buy a bag of a hundred?
No. A small signal transistor is a part you count out, and that is how we sell it: one to replace a single failed stage, three or four if you want spares in the drawer, up to what is on the shelf. The usual alternative is a hundred-piece assortment where the markings are anyone's guess and you sort the good from the questionable yourself. Here you are buying against the photographed, marked KEC piece in front of you and taking only the count you need. Shipping is $8 flat rate and free once your order passes $28, and orders leave our Idaho warehouse the same or next business day.
Japanese audio boards of that era were full of quiet PNP devices like this one, doing the unglamorous work behind the stage everybody actually hears. Put an A562 Y back where the original sat, and the machine gets to go on being itself.
