How to find Songle Relay?

Hi,

I’m new to KiCad and am finding it incredibly useful. Thanks!

I can’t seem to find a relay I am looking for (Songle SRD-5VDC-SL-C (PCB mount)). Just wondering if there is a suitable substitute in the list (G5Q-1A) or if I should should I make a new component?

Looking to drive from an RPi (5V and low current) to activate.

Thanks

Adam

Clasic sugar cube case relay. Footprint: Relay_SANYOU_SRD_Series_Form_C from Relays_THT,pretty library. For the schematic symbol: use G5Q-1 from relays.lib but you have to edit pin numbers to match this footprint.

BTW: Don’t know why KiCad footprints for standard power relays have pins numbered as 1, 2, 3, etc. while many of manufactures enumerate relay pins as follows: A1, A2 for coil and 11, 12, 14, 21, 22, 24, etc. for contacts (EN 50005 standard)?

It has a new name now it seems.
Relay_SPDT_SANYOU_SRD_Series_Form_C

There are some relays with naming A1,A2
As far as i can tell (I have not checked all symbols/footprints) the names listed in the datasheet are taken. (If the datasheet does not give a name for the pins, it seems numbers are preferred.)

For example the first symbol in the relays lib AZ850-x (current master branch) uses pin numbers in the datasheet. http://www.azettler.com/pdfs/az850.pdf
The next series are the FINDER-40.52 relays. These use A1,A2 in the datasheet. As does the kicad symbol. https://gfinder.findernet.com/assets/Series/354/S30EN.pdf (The footprint in relays_tht has the same pin names of course.)

These are symbols I contribute few years ago. The AZ850 has pin numbers because its very close to DIL housings. But for other relays we need to keep one standard, to make it better interchangeable.
