Title: Is lcsc legit?
Post by: redgear on September 06, 2020, 03:15:56 pm
I am looking to buy Omron G4A-1A-PE DC12 relays. They cost about 9.6 on Digikey but they cost only 0.85 on LCSC. How is this possible? Are they legit.

From a quick Google, some other western sources offer a one off price of $3 or so. The one off price from LCSC is actually $1.335. $0.85 is their 100 off price. Such is the pricing you get from different sources. A high volume negotiated price for a relay like that should be well under $1 in any country.

Yes, they are a large stockist and will happily sell you large quantities. It's part of a group comprising JLCPCB and EasyEDA also.

Digikey are for people who want small quantities of stuff for prototyping from a one stop shop, and they want them tomorrow. You have to pay a lot for services like that. Sadly, a lot of engineers reject parts from their designs as too expensive, based on looking up Digikey's small volumes for prototyping prices. It really skews some designs.

I purchased G2R relays from LCSC around $1.60 each in ~30 quantity, local digikey wanted around $7.5-$8 each in comparable quantity.

Even if I purchased 5000 of them and spent $22k with digikey, it's still 3x the price of LCSC (in 30 quantity!!!). I can't see how a manufacturer would want to go with digikey.

Manufacturers don't shop at DigiMouser, except when developing prototypes for which the cost of the components is basically an irrelevance, but the cost of waiting a week for them matters...

LCSC are legit, I have had no problems with them, the place that screams 'who knows what there really are' is Ebay and Amazon when buying the generally unobtanium.

Pricing of some components at distros is strange. Some are priced reasonably, some not. For example I buy Bourns 0805 polyfuses at LCSC at around 3 cents piece @ qty of 100, at Digikey the same thing costs $0.14, at mouser $0.30 at Qty of 3000. The most strange thing is they sell Chinese brand polyfuses at about the same price. And they are completely legit. Bourns polyfuses are very distinguishable from everything else since they are gold plated and made way more neatly than anything I've seen.

I've read about your issue. Dunno what you ordered and what received. They sell pretty crappy parts from Chinese manufacturers but you know that you are buying something low tier. Did they even look like polyfuses? As someone said may be mispick. Do you have a photo? So far I have not received counterfeits but some cheap Chinese connectors they sell are crap. For connectors, I ordered same type from various manufacturers, then inspected/tested them and made a list of what's acceptable for further ordering. Bourns polyfuses are not something random though and don't look generic unlike most of them.

If they actually looked like on the picture, I doubt they were fake. Probably a defective batch.
