Is there a KiCad symbol and footprint for the SR05?
Yes. The symbol is EasyEDA_Pro:SR05 and the footprint Package_TO_SOT_SMD:SOT-143, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SR05?
SOT-143, with 4 pins. Its footprint is drawn on this page.
Where is the SR05 datasheet?
TECH PUBLIC publishes it: the Datasheet link on this page opens it.
Where can I order the SR05?
JLCPCB lists it as part C521962, with 11,746 in stock; the sellers' links on this page open their listings.
What can replace the SR05?
Parts like it in the library: the PRTR5V0U2X by TECH PUBLIC, the PRTR5V0U2X by UMW, the PRTR5V0U2X-ES by ElecSuper and the SP0503BAHTG by GOODWORK. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SR05?
14 boards in 10 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
