K4B2G1646F-BYMA – DDR3 SDRAM – Samsung

Samsung K4B2G1646F-BYMA is a 2Gb DDR3L SDRAM (F-die) organized as 128M x16 in a 96-ball FBGA package, rated DDR3-1866 with 1.35V/1.5V operation. Now end-of-life and hard to source – available for RFQ at Pacific Component Xchange.

The Samsung K4B2G1646F-BYMA is a 2-gigabit DDR3 SDRAM device from Samsung’s F-die generation, organized as 128M x16 and supplied in a space-efficient 96-ball FBGA package. Rated at the DDR3-1866 speed grade, it delivers data rates up to 1866 Mbps per pin (933 MHz clock) and is built on a lead-free, halogen-free (RoHS-compliant) process. As an F-die low-voltage device it supports both standard 1.5V (DDR3) and low-voltage 1.35V (DDR3L) operation, making it a flexible drop-in for a wide range of legacy designs.

This part is now end-of-life (obsolete) and has little to no authorized-distributor availability, making it a classic hard-to-find memory component. Pacific Component Xchange maintains inventory of these scarce devices to keep your production lines and field-service builds running.
