Questions

Is there a KiCad symbol and footprint for the MSL3085BT?

Yes. The symbol is EasyEDA_Cloud:MSL3085BT, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the MSL3085BT?

TQFN-40(6x6), with 41 pins.

Where is the MSL3085BT datasheet?

Microchip Technology publishes it: the Datasheet link on this page opens it.

Where can I order the MSL3085BT?

JLCPCB lists it as part C6916672, with 0 in stock; the sellers' links on this page open their listings.

What can replace the MSL3085BT?

Parts like it in the library: the THL3501-B by California Eastern Laboratories, the MAX25530GTL/V+ by Maxim Integrated (Analog Devices) and the THL3501 by THine Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
