Questions

Is there a KiCad symbol and footprint for the PT1903?

Yes. The symbol is EasyEDA_Cloud:PT1903 and the footprint EasyEDA_Cloud:ESOP-8_L4.9-W3.9-P1.27-LS6.0-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the PT1903?

ESOP-8, with 9 pins. Its footprint is drawn on this page.

Where is the PT1903 datasheet?

PTC publishes it: the Datasheet link on this page opens it.

Where can I order the PT1903?

JLCPCB lists it as part C481967, with 0 in stock; the sellers' links on this page open their listings.

What can replace the PT1903?

Parts like it in the library: the TX6210 by XDS, the TX6410B by XDS, the KP18002ESPA by Kiwi Instruments and the TX6126 by XDS. Check their datasheets: a part that fits the footprint may still differ in its ratings.
