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 C13761, with 16,381 in stock; the sellers' links on this page open their listings.
Parts like it in the library: the 6BS04000F20UCG by SJK, the HC-49/U-S4000000ABJB by CITIZEN, the B04000J089 by ECEC and the KUS040002020 by KYX. Check their datasheets: a part that fits the footprint may still differ in its ratings.
