LCSC

EasyEDA's parts store

I purchased some parts from LCSC.com. It is the same company as EasyEDA.com and they will ship the parts for free with your PCB order. When you checkout you select "ship with PCB" and the shipping cost is removed. You use your EasyEDA login to login to LCSC.

The prices are good for the parts I could find. I got several different 1n4148 diodes and some resistors. I also found a MOSFET that works with the backlight circuits I use.

Here's the parts I bought:

Semtech 1n4148 (Thin wire leads)

The Semtech diodes have very thin leads. 0.39mm. They are the cheapest diodes on LCSC. I would not recommend them. The other 3 brands of 1n4148 diodes have 0.48mm leads. It is very difficult to see any difference between them physically. All diodes come on tape. The tape is fresh and not old and gummy so comes off clean without leaving sticky residue. Prices ranged from $0.009 to $0.0059 each in quantities of 500.

They did not have 470ohm resistors, which is what I usually use. The closest was 510ohm, which is close enough. Prices for the resistors were very good. $5.55 for 1500. I got 100 of the 100ohm and 100Kohm @ $0.52 for 100. These were also on tape.

The MOSFETs were $0.63 for 10. Dirt cheap.

Example packing slip. Looks like all prices are not in USD.
Things I could not find:
  • Machine pin sockets (24pin wide)
  • Through hole LEDs appropriate for backlighting
  • Hardware
The search engine is nothing like Digikey or Mouser. Finding the part you want will take you some time. You may even have to read the datasheets to get the details on the parts. Many of the brands are Chinese and their datasheets are in Chinese. The prices are very good though, if you can find what you need.
