Overview
The LM75AIMX is a temperature Sensor made by Texas Instruments in a SOIC-8 package with 8 pins. -55℃~+125℃ 2.7V~5.5V 300ms 500uA 9bit I2C ±2℃ SOIC-8 Temperature Sensors ROHS.
PCBKit's library has its KiCad symbol (Sensors:LM75, from CERN's library) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. 27,570 are in stock at JLCPCB (part C477979).

Is there a KiCad symbol and footprint for the LM75AIMX?
Yes. The symbol is Sensors:LM75 and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM75AIMX?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the LM75AIMX datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM75AIMX?
JLCPCB lists it as part C477979, with 27,570 in stock; the sellers' links on this page open their listings.
What can replace the LM75AIMX?
Parts like it in the library: the DS18B20Z by UMW, the LM75AD by NXP Semiconductors, the LM75BD(UMW) by UMW and the LM35DMX by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
