K4B4G1646E-BCMA – DDR3 SDRAM – Samsung

The Samsung K4B4G1646E-BCMA is a 4Gb DDR3 SDRAM organized as 256M x 16, rated for DDR3-1866 (1866 Mbps) operation at 1.5V in a 96-ball FBGA package. Available now for RFQ at Pacific Component Xchange.

The Samsung K4B4G1646E-BCMA is a 4-gigabit DDR3 SDRAM device organized as 256M x 16, housed in a 96-ball fine-pitch ball grid array (FBGA) package. The “-BCMA” speed-grade suffix designates a DDR3-1866 rating, delivering a data transfer rate of 1866 Mbps per pin at a 933 MHz clock and CAS latency of 13, operating from a nominal 1.5V supply. It is a popular x16 DRAM die used in embedded systems, networking equipment, and graphics or display subsystems where a single high-density device simplifies board layout.

This part is part of Samsung’s K4B4G1646E family, in which the -BCK0 (DDR3-1600), -BCMA (DDR3-1866), and -BCNB (DDR3-2133) variants share a common package and pinout, allowing higher-speed grades to drop into the same PCB footprint. As DDR3 transitions out of mainstream production, the K4B4G1646E-BCMA has become increasingly difficult to source through authorized channels, making it a frequent target for end-of-life buys and last-time procurement.
