Overview
The ATS04ASM-1 is a crystal made by CTS Electronic Components in a HC-49S-SMD package with 2 pins.
PCBKit's library has its KiCad symbol (Device:Crystal, from KiCad's library) and its footprint (Crystal:Crystal_SMD_HC49-SD, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C6747339).

Is there a KiCad symbol and footprint for the ATS04ASM-1?
Yes. The symbol is Device:Crystal and the footprint Crystal:Crystal_SMD_HC49-SD, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ATS04ASM-1?
HC-49S-SMD, with 2 pins. Its footprint is drawn on this page.
Where is the ATS04ASM-1 datasheet?
CTS Electronic Components publishes it: the Datasheet link on this page opens it.
Where can I order the ATS04ASM-1?
JLCPCB lists it as part C6747339, with 0 in stock; the sellers' links on this page open their listings.
What can replace the ATS04ASM-1?
Parts like it in the library: the X49SM4MSD2SC by YXC, the H6OEL89CSC-SUGYLC-4M by YXC, the H6OEL89CSI-SUGYLC-4M by YXC and the HY4M49SSMDOB1R20 by Huiyuan crystal. Check their datasheets: a part that fits the footprint may still differ in its ratings.
