Questions
Is there a KiCad symbol and footprint for the CH442E?
Yes. The symbol is EasyEDA_Pro:CH442E and the footprint Package_SO:MSOP-10_3x3mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CH442E?
MSOP-10, with 10 pins. Its footprint is drawn on this page.
Where is the CH442E datasheet?
WCH (Nanjing Qinheng Microelectronics) publishes it: the Datasheet link on this page opens it.
Where can I order the CH442E?
JLCPCB lists it as part C150097, with 19,695 in stock; the sellers' links on this page open their listings.
What can replace the CH442E?
Parts like it in the library: the FSUSB42MUX by onsemi, the BL1555MM by BL, the RS2105XN by Jiangsu RUNIC Tech and the BL1532MSOP by BL. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the CH442E?
2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
