The CY7C1613KV18-333BZXC is a 144 Mbit QDR II synchronous SRAM organized as 8M x 18 bits, clocked at 333 MHz over a parallel interface.
Yes, both parts share the same 165-FBGA footprint, 8M x 18 organization, supply voltage, and temperature grade. The 333 MHz part is a functional drop-in for the 550 MHz part if the system clock is 333 MHz or lower.
