Is there a KiCad symbol and footprint for the LR4054-T?
Yes. The symbol is EasyEDA_Cloud:JTD4054H and the footprint Package_TO_SOT_SMD:SOT-23-5, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LR4054-T?
SOT-23-5L, with 5 pins. Its footprint is drawn on this page.
Where is the LR4054-T datasheet?
LR publishes it: the Datasheet link on this page opens it.
Where can I order the LR4054-T?
JLCPCB lists it as part C5336483, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LR4054-T?
Parts like it in the library: the TP4054 by JSMSEMI, the TP4054-42-SOT25R by TOPPOWER, the MCP73832-2ACI/OT by Microchip Technology and the TP4054 by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the LR4054-T?
4 boards in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
