Overview
The 24LCS21A/SN is an EEPROM made by Microchip Technology in a SOIC-8 package with 8 pins. 0℃~+70℃ 10ms 1Kbit 2.5V~5.5V 400kHz I2C SOIC-8 EEPROM ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:24LCS21A-I_SNG, from EasyEDA) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C1351708).

Questions
Is there a KiCad symbol and footprint for the 24LCS21A/SN?
Yes. The symbol is EasyEDA_Cloud:24LCS21A-I_SNG 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 24LCS21A/SN?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the 24LCS21A/SN datasheet?
Microchip Technology publishes it: the Datasheet link on this page opens it.
Where can I order the 24LCS21A/SN?
JLCPCB lists it as part C1351708, with 0 in stock; the sellers' links on this page open their listings.
What can replace the 24LCS21A/SN?
Parts like it in the library: the M24C02-WMN6TP by STMicroelectronics, the M24C02-RMN6TP by STMicroelectronics, the 24LC256T-I/SN by Microchip Technology and the CAT24C08WI-GT3 by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
