K4UBE3D4AM-MGCJ – LPDDR4X SDRAM – Samsung

The Samsung K4UBE3D4AM-MGCJ is a 32Gb LPDDR4X mobile DRAM (1Gx32, LPDDR4X-3733) in a 200-ball FBGA package, used in smartphones, tablets, and embedded systems. This discontinued, hard-to-find device is available for RFQ from Pacific Component Xchange.

The Samsung K4UBE3D4AM-MGCJ is a low-power LPDDR4X SDRAM (mobile DRAM) device belonging to Samsung’s K4UBE3D4AM family. Distributor data describes this specific -MGCJ variant as a 32Gb (1Gx32) device rated at the LPDDR4X-3733 data rate, supplied in a compact 200-ball FBGA, the standard form factor for Samsung LPDDR4X components used in space-constrained mobile and embedded designs. As an LPDDR4X-class memory, it is engineered for high bandwidth at reduced I/O voltage, helping extend battery life in portable and always-on applications.

This part has been discontinued by Samsung, making it difficult to source through authorized distribution. Pacific Component Xchange maintains inventory of this obsolete device to support production continuity, repair, and long-lifecycle programs.
