Electronic component scams: some companies are remarkably open about it.

If you buy components on AliExpress or similar online markets, you're probably already familiar with getting faux goods. If you're lucky, it's a clone of the actual part you wanted (transistor, opamp, whatever) with similar specs. If you're less lucky, you get a part that's the same general type, but not the one you wanted - order a transistor with particular characteristics, but receive another transistor type entirely, that doesn't work the same way.

And of course, if you're truly unlucky or you buy the cheapest listing you can find, you get a package with a completely random bit of silicon in it (order a JFET or MOSFET, receive a BJT, possibly with a different pinout...) or even a package with no actual electronics in it (receive a DIP package with proper leads on it, but cut it open and the leads aren't connected to anything, and there's no silicon die in it at all).

I happened to see this listing on AliBaba, the wholesale / manufacturer site related to AliExpress:
alibaba.com/product-detail/Scr

If I read it right, they're offering to sell you a cloned part, but they'll silkscreen whatever fake info you want onto the package, so you can sell it as a genuine name-brand part. Or maybe they're offering to remark any component you want, who knows - I'm not going to contact them to find out.

Pretty brazen.

Schematic: "2022 - We've updated the circuit design to use widely-available part AB1234DL rather than the impossible-to-find one the original design used!"

<search Newark/RS/Element14>

Website 2025: "AB1234DL: obsolete, not available to order"

Sigh.

I thought it might be fun to create some original random sockets:
<edit>: I will post updates and variatons in here, added a TAG #skt2me

Step 1: Take a previously single-div drawing

Step 2: Copy the code into a custom toggle switch

Step 3: ???

Step 4: Profit

Just a brief #factoid to perhaps save other #electronics #hobbyists some time.

#BigClive frequently uses a particular type of crimp-contact-and-housing as a universal socket for LEDs and other leaded components. Not just any such connector will do; various #JST, "#Dupont", and others won't work, because they only grasp pins of one particular size and/or shape. If the lead is too big, it won't go in, and if it's too small, it won't stay in.

If you want to use these connectors - and note you can get the housings with more than 2 contacts, so you can use them for transistors or weirder things too - the magic search term is "KF2510".

The reason these work as universal sockets for leaded components is because the contact is a spring that pushes from only one side of the housing, pressing the inserted contact or lead against the far side of the housing, and therefore provides a friction fit for any size lead (within reason). Most crimp connectors instead have particular shapes for their contacts and will only "grab" something the right size and shape.
