content: Half price of Mouser is not surprising for genuine parts. I'm sure they will be fine.If you really want cheap and risky then get used ones from aliexpress:https://www.aliexpress.com/i/2255800134529480.html

content: LCSC is a serious asian distributor. You can't compare it with random sellers on Aliexpress.

content: I have had zero issues with LCSC quality, they are just mass volume seller. I have made mistakes ordering parts that had confusing descriptions/like model numbers. Their handling time can be hit or miss 1-2 days is more like 2-4 and 3-4 can be 6-8 some times.I typically order once a month for non rush work. After a while you will have so many reels of parts you will not know what to do with them all.Here is a LCSC order i Unboxed.

content: Quote from: strawberry on August 17, 2023, 06:36:53 amI'd say approximately the same as getting defective/fake parts for the full price on Digikey or Mouser.

content: The only issue I've ever had is 75HC595's that had reduced functionality - this was stated in the datasheet, just annoying that they used the same part number.Time-wise I find that higher value orders (>GBP500) tend to sit around for a few days before being dipatched.

content: Starting Jan 2023, we have started to specify alternative part numbers fromLCSC, when we manufacture (e.g. assemble) PCB in China. Primary partnumbers are always Digikey or Mouser, secondary we now use LCSC, and<I can't remember the name right now, will edit later>. [Finally remembered: octoparts]So far, we have not seen any issues. We usually do not allow the PCBassembly house to substitute components. We always ask them to checkwith us first.Cheers,luudee

Also stated in the datasheet.Its kind of good and bad, good that you don't have to search through 100 different random parts to find something similar in function to a 595. But bad if you bought it thinking its the same part. If their search were better it would help.

content: Even on Digikey, you're going to see 1N4148's from different manufacturers with different specs:100 V 200mA onsemi75V 300mA SMC75V 150mA Good-Ark Semiconductor100V, 150mA Taiwan Semiconductor Corporation

content: Quote from: Kim Christensen on August 21, 2023, 10:50:13 pmTrue, which is where Digikey search and filtering helps. In the case of LCSC they were missing the capacitance rating.LCSC do have voltage, current, power, and leakage. But many times they are not yet entered into the website, so are just blank.

content: Quote from: thm_w on August 21, 2023, 11:17:00 pmI've got into a habit of always double-checking parameters of the part I'm ordering against the manufactorer's datasheet as I've seen them wrong or absent in distributors I've used (DK, Mouser, LCSC).
