Yes. The symbol is Device:Crystal and the footprint EasyEDA_Cloud:HC-49US_L11.5-W4.5-P4.88, both drawn on this page. PCBKit places them on a board for you when you design with it.
HC-49S, with 2 pins. Its footprint is drawn on this page.
YXC publishes it: the Datasheet link on this page opens it.
JLCPCB lists it as part C2198, with 983 in stock; the sellers' links on this page open their listings.
Parts like it in the library: the 6BS05000F20UCG by SJK, the ECS-50-S-4X by ECS, the H6OEL89CSC-SUGYLC-5M by YXC and the X49SM5MSD2SC by YXC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
