content: Ok guy, since many of us order from AliExpress, some of us may want a list ofknown go-toorknown stay-away-from sellers. Let’s see how this one works out.I ordered this for experimentation and a repair:It is clear that the order is forCD54, and the product measures5mm X 4.5mm.[See attached photo 1]I got something considerably smallerSee attached photos - One of the received inductor is in the caliper and the smd-strip (on one photo, the strip is rubber-band tied to the ruler part) I also included a dead 5mm inductor in the photo for scale.The received inductors measured 2.99mm X 2.1mm. Looking up datasheets, itlooks like a CD32 at 3.1+-0.2mm.So, I messaged the seller. I want to work with him before I open a dispute.Since this is mostly for experimentation, I feel I can make-do. But I want to be compensated for the wrong (cheaper) product. So, I suggest rather than mailing it back and forth, mail me three 5V 1117 and we will call it even. They sell the 1117 for 20cents each, so that is $0.60 worth. A small compensation as much for the principle as it is for being short-changed.The seller message back: he thinks I am wrong since they never had CD32. I think it may be a case where the seller probably got the wrong item themselves and may not even know it. I had a similar problem before on eBay: That eBay seller sold me FT232RL version of the Arduino NANO but shipped me the CH340G version. After a few exchanges, it became apparently to me that other seller didn’t know FT232RL & CH340G versions are different. That eBay seller made good by giving me a small compensation. So, with this AliExpress seller I am giving him the benefit of the doubt.Well, I think it is CD32 – do you think I am wrong or the seller is wrong?Do you think my proposal is fair?I am going to email the measurement photos I attached below. What do you think? I intend to invite the seller to see this as well.Rick

content: Does it have right inductance at least? Once I ordered on ebay LD7535 in SOT-26. Part which arrived was something in SOT-25 package. Seller agreed to fix this and sent me a the replacement. This time it was something in SOT-26 but with wrong marking. I measured the part with multimeter in the hope that it could be some clone of it as there are few of them but obviously it was something completely wrong. If I soldered it into PSU, likely would get a blown MOSFET at minimum.

content: Quote from: wraper on April 15, 2015, 07:44:24 pmThey are 101's. So it should be right inductance. But I doubt it can carry 0.7A given how thin the wire is.The way you posted with "...right inductance at least?" I take it you agree with me that this is the wrong size?

content: You are right... but... over $0.60?It will probably cost him a lot more than that to send out the parts. If I was him I would propose to give you give you a discount towards another order - so instead of taking a loss he simply earns less than usual... takes the sting out of a return.But if you refused I'd just ship the correct parts of take your offer for the 3 x 1117's.But again - and maybe it sounds like a dick thing to say... but this over 60 cents???

content: BTW, IMO better to ask a refund rather than making strange proposals. Also I would never buy any voltage regulators from china as you never know what shite is inside, quiet likely they are fake as only lazy doesn't make them. And the worst part is, if it fails, it can destroy all other parts too.

content: Quote from: Rick Law on April 15, 2015, 07:05:17 pmI seriously doubt they do have any stock at all. This might be just some guy(s) who gets the parts from Shenzhen market once thy are ordered.

content: Quote from: Corporate666 on April 15, 2015, 07:51:05 pmYou got a point there. I asked for some compensation for the principal of it. I'll wait and see if I get more opinion/options here. In a couple of days, I will propose a different solution - the one you recommended and ask for a discount on the next order.Rick

content: I know you want to be nice and talk to them first, but imo, this is what the dispute process is for, people get burned on ali because they don't use the dispute process.Althouh if it was me, i'd just give a bad feedback and move on with life if i can still use the parts.

content: I think you are confusing him with the voltage regulator thing.communication is hard enough as it is.he should mail you the correct parts or refund the full amount. there is no other solution that I would accept. I could care less what his costs are. if you don't deliver what you advertise, you don't even deserve the right (these days) to BE a business, selling things.the bar to be a 'business' is just too low, for my taste. people who don't even know what the 'little part things' are - are selling them. makes no sense to me! I bought a DIY audio thing from ebay/china, I asked for the schematic and the seller did not know what that word meant. it was hard to explain and I had to send him samples of what a schematic is! THAT guy should not be a seller, and it sounds like your guy also is in the same kind of shape.it just annoys me that any idiot can be a 'parts seller' and 90% of them are all clueless idiots who don't know, don't care and won't change. its hard to find the REAL ones, anymore ;(

content: Quote from: linux-works on April 15, 2015, 09:35:27 pmagreed, i have dealt with a few chinese manufacturers who have limited english skills, they will rarely say "sorry i dont understand", preferring to make an assumption instead.Writing clear english thats easy to understand helps a lot. Generally they want to do the right thing but sometimes struggle to understand due to language.

content: Quote from: Rick Law on April 15, 2015, 08:25:50 pmI dont think that is the correct way of dealing with Chinese sellers. If you got something you did not order, full refund. No partial refund, I don't care if they shipped an Android tablet instead of a 555. And no repeated shipping, discount or anything like that. If you still need the thing, just buy it again, that resets the purchase protection. By the time the next mail arrives, your purchase protection will be pretty much over, and nothing protects you if you have a gummybear in your mail instead of the thing you ordered.As I ordered 100s of items from there after a while I got ruthless for scams and shenanigans.

content: Quote from: Rick Law on April 15, 2015, 07:05:17 pmI don't know if that will work. That guys don't know yet what's inside the next container that will arrive on their doorstep next week.Maybe a seller+article+date specified list could work.

content: On the principal of it, I submitted a dispute. The seller accepted responsibility quickly, issued a small refund ($1). I am happy with the situation. I am pleased with the seller and if he has things I need, I would try him again.Many seller are drop-shippers. They could be fooled by their supplier just the same. Or he simply got the wrong stuff himself and may not even have noticed it. Lacking buyer's feedback, other buyers will get the wrong stuff too.Mistake is less the issue. It is their action after that matter more than the mistake itself. So, despite his first mistake (with me), I will try him again and I consider him an honest guy who fixes his errors.Now, I have a whole dollar to spend again... I should think about upgrading my scope or something...
