Questions

Is there a KiCad symbol and footprint for the MT7281?

Yes. The symbol is EasyEDA_Cloud:MT7281 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 MT7281?

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

Where is the MT7281 datasheet?

MAXIC Tech publishes it: the Datasheet link on this page opens it.

Where can I order the MT7281?

JLCPCB lists it as part C216700, with 0 in stock; the sellers' links on this page open their listings.

What can replace the MT7281?

Parts like it in the library: the HI1246E by Hichips, the OC5038 by OCX, the OC5028B by OCX and the HI12410W by Hichips. Check their datasheets: a part that fits the footprint may still differ in its ratings.
