This is a list of a few standard switching MOSFETs from LCSC that I use regularly.
The lists are sorted by ascending size. Power MOSFET is defined as >= 1A continous drain current.
TODO
As far as I can tell from the JST website, JST does not sell any SMD variants of the JST XH series.
However, LCSC lists some 3rd party SMD connectors as VH 3.96mm, such as:
So far I have not tested those and I don’t know yet if they are compatible with the standard JST housings.
Generally, I always recommend going with metal-shielded RJ45 ports since those tend not to break as often.
If you want to buy more than, say, 10pcs, you can check out LCSC’s Ethernet Connectors / Modular Connectors lineup. The very good prices compensate for the shipping fee even when buying only medium quantities.
Note that it’s easy to mix up models with and without magnetics at the moment as there is no suitable filter. It’s easiest to just look at the length of the connector – RJ45 connectors without magnetics are almost cubic in size (i.e. length in the direction where you insert the connector is equal to the width) whereas connectors with magnetics are much longer. Nevertheless, always check the datasheet.

@ 100pcsAs with most commodity PCB components, LCSC is a good place to find cheap connectors if you want to buy more than 10 pcs or so (due to the shipping fees).
These are listed in AC/DC power connectors. In order to find them quickly, select the Package=Plugin
filter and select In Stock
and then sort by price (ascending).
Using this method, you can easily find parts such as:

If you are reading this post, you probably bought a “DuPont” crimp connector set from Amazon, eBay or AliExpress and are now looking for additional components.
I found the exact same connectors that came with my set by looking through hundreds of products on LCSC. Currently, I have no DigiKey or Mouser link, but I will update this post if I find one in the future.
Also see Where to find “DuPont” style crimp terminals?
Note that I only looked for DuPont style connector with a plastic leaf spring on the side of every terminal housing. There are more or less similar types without that leaf spring but these appear to be for other (even if similar) types of crimp contacts.
We do not imply any compatibility, so check it by yourself.

As for most parts, if you order more than just a few pcs, LCSC is the cheapest source of these components (however, you need to consider the rather expensive shipping costs).
Here’s some SMA connectors I’ve used:
Note that I don’t use them in typical RF applications, so I don’t have any information on impedance matching or accuracy etc.
The 74HC4051 and its variants such as the CD74HC4051 have an input called INH
or ~E
depending on the manufacturer.
Typically you should hard-connect this pin to GND
in order to always enable the multiplexer.
Whenever you want to disable the multiplexer (i.e. none of the inputs is connected to the output, connect this pin to Vcc
temporarily.

LCSC offers the SHOU HAN MSK12CO2-SZ microswitch for about 0,023€/pc @ 1kpc. One of the disadvantages of this switch is that even though it is a pure SMD (no through soldering required), it is shipping as bulk in a bag and not as tape. Therefore, it is not suitable for all commercial assembly lines and needs to be assembled manually.
But at least it is cheap – that is, if you buy enough stuff to justify the high LCSC shipping costs.
The KiCAD footprint for this switch is Button_Switch_SMD:SW_SPDT_PCM12
. Even though it’s a different switch than the C&K PCM12, it’s mostly compatible footprint-wise – even though the drill sizes are very slightly off, the footprint works well.
This switch is likely rated to DC12V, 50mA (listed as such on the LCSC website). However, from the datasheet, the exact rating is unclear, it mostly covers the test conditions
If you are looking for an alternative suitable for automated assembly, take a look at the SK-3296S-01-L1 which comes as a taped reel. It is almost 35% more expensive but given that it’s still just 0,031€/pc @1kpc and given that you’re likely not a chinese electronics designer in extreme mass manufacturing, the price is hardly worth thinking about.
It is exactly compatible footprint-wise with the C&K PCM12, so the KiCAD Button_Switch_SMD:SW_SPDT_PCM12
works even better.
This switch is rated at DC12V, 50mA.
This is the MK-13C03-G010 which is rated at 6V 1A or 12V 0.5A. This type of current rating with voltage is related to arcing when breaking the contact.
It is priced around 0,11€/pc @1kpc.
This one is compatible with the C&K PCM13 (but rated at higher current), so use the Button_Switch_SMD:SW_SPDT_PCM13
As for most components, LCSC has the best prices if you want to order more than just a few MOSFETs (due to the high shipping fees)
These are mostly SOT23-3, so the don’t provide good power dissipation. These are mostly used for switching voltages on and off and not for linear applications.
As for most parts, if you order more than just a few, LCSC is the cheapest source of these components (however, you need to consider the rather expensive shipping costs).

On the MAX11200EEE+
and the MAX112100EEE+
, bit 3 of the command byte is named IMPD
but this bit is never described in detail in the datasheet.
The meaning of this bit is Immediate power-down
. When you set it to 1
, the IC will switch to power-down mode. This is evidenced by the power-down example in Table 8
in the datasheet.
The MAX11200EEE+
and the MAX112100EEE+
operate using SPI Mode 0
. Therefore, CPHA=0
& CPOL=0
.

Generally, SMD ferrites of a given size are characterized by:
100 MHz
)100 Ω @ 100 MHz
) do not filter EMI that well, but also distort your data signals less. Use them for high speed signals above 1 MHz
1kΩ @ 100 MHz
, filter EMI really well but will distort any high speed signal. Use them for low speed signals below 1 MHz

is typically fine)As with most passive parts, LCSC generally has the lowest pricing if you buy a bunch of parts.
Keep in mind the expensive shipping, but since they are often 50 times cheaper (!) than other distributors, it might be worth it even if just ordering a reel of ferrites.
