G3MB-202p Solid state ralay part and opinion request

2024-10-19 16_51_27-Window
Hello, doing a board project for ESP32, I have to decide which relay to use to turn on some LED lights and low consumption things, and while studying I found this solid state relay, which comes with an octocoupler already inside, so It can be activated with a transistor that makes the 5v flow. but, unfortunately, I can’t find just the module to solder it to the board. It seems like a tremendous component to me, what do you think? Is it better? Does anyone have it?

A google search of the form “fritzing part solid state relay” (which is the best way to find parts) indicates there are several in the forums. One of those may do what you want (I think the G3MB part is actually a module with screw terminals which may not be what you want.) Have a look and see if an available part will do what you need.

Hi Peter, thanks, I only found these fritzing-parts/OMRON G3MB-202p.fzpz at master · rayros/fritzing-parts · GitHub
but the footprint is not the correct.

Size:

The real size:

This part should do what you want. It would be a good bet to print out the pcb footprint at 1:1 scale and compare it to a real part as I don’t have one.

edit

Nov 2024 Replace part with one with a corrected breadboard and pcb.

It works nice!! thank you, Peter!

Dear vanepp, i have a problem:

imagen

the separation in between central pins must be 2.54 * 4 = 10.16 cm

Also, my g3mb-202p has the pins on the left side, I do not know why datasheet shows on the right side

That is why the print the footprint out at 1:1 scale and compare it to a real part is there to avoid mistakes like this. The datasheet is correct, it says bottom view (which is the opposite of how datasheets normally are) and thus the part is inverted in Y. I have replaced the part with a corrected version although you should print the footprint out at 1:1 scale and compare it to a real part before ordering boards to verify it is now correct. You will need to delete the current part in youe mine parts bin, then shutdown and restart Fritzing before it will let you load the new part. Sorry for the screw ups!

Do not worry, you are helping me a lot, and thanks for your advice, it is OK, boars are just samples.
i fond files on Documents\Fritzing\parts\user

Thanks!

It should be in your mine parts bin (although it may not be if you have at some point answered the questions about saving the parts bin and saving the parts differently (i.e. yes to one and no to the other.) Normally the search should let you delete the part. If it won’t there are things we can do but it gets complicated. If you have only that part in your mine parts bin and nothing else you can just delete the user directories and the part will be deleted like this (shutdown Fritzing before doing this!)

"
There are two user directories (with your parts and the parts database) which don’t get touched during an install (to not affect your sketches during upgrades). On Windows they are in

c:\users\username\AppData\Fritzing\roaming\Fritzing (which is a hidden directory so you need to enable hidden directories in explorer) and

c:\Users\username\My Documents\Fritzing (where username is your windows id)

If you don’t have any parts or sketches you want to keep you can just delete those two directories and Fritzing will recreate them, or you can move them aside by renaming them if you want to keep something in them.

linux

~/Documents/Fritzing/parts
~/.config/Fritzing

Mac

/Users/username/Documents/Fritzing/parts
~/.config/Fritzing"

Note it is a wise idea to rename the directories in case of problems. If you then shut down Fritzing, rename the directories to their original names and restart Fritzing they will be restored. If you delete them Fritzing will create new empty directories (losing all your saved parts!) The correct way to delete a part is this:

Here the relay is the only thing in the mine parts bin

right click on it and click remove part (I have seen cases where the remove part is greyed out, but not yet figured out how to reproduce it to report it as a bug!)

click yes here

and it apparently deletes the part. In fact it has not deleted the part and won’t until you shut down Frtizing and answer the questions correctly.

click the x in the upper right corner to exit Fritzing and answer yes to save the parts (which in this case will delete the part.) This is one of the two questions that you need to answer the same to make the deletion work.

this one you can answer no to as you don’t likely want to save the sketch.

You need to answer yes here to actually delete the part, this is the other question that answering the opposite way to the first one will potentially remove the part from the parts bin but leave the part present. Fritizng will then shut down and the part should be deleted.

it was very complicated, will be nice if there is a option to full delete or ovberwrite the part

Yep, I have filed an enhancement request to make part deletion work without a shutdown (which I think should be possible), but no action so far. As long as you got it done though …
