Is there a KiCad symbol and footprint for the CDLL4148?
Yes. The symbol is Device:D and the footprint Diode_SMD:D_MiniMELF, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CDLL4148?
DO-213AA, with 2 pins. Its footprint is drawn on this page.
Where is the CDLL4148 datasheet?
Microchip Technology publishes it: the Datasheet link on this page opens it.
Where can I order the CDLL4148?
JLCPCB lists it as part C17688656, with 0 in stock; the sellers' links on this page open their listings.
What can replace the CDLL4148?
Parts like it in the library: the LL4148 by MDD, the LL4148PF by STMicroelectronics, the LL4148-GS08 by Vishay Intertechnology and the LL4148 by LGE. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the CDLL4148?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
