H5TC4G63EFR-RDAR – DDR3L SDRAM – SK Hynix

The SK Hynix H5TC4G63EFR-RDAR is a 4Gb DDR3L SDRAM organized as 256M x 16, rated at DDR3-1866 (13-13-13) in a 96-ball FBGA package operating at 1.35V. This legacy, hard-to-find memory device is available for immediate quote at Pacific Component Xchange.

The SK Hynix H5TC4G63EFR-RDAR is a 4Gb (4 gigabit) low-power DDR3L Synchronous DRAM organized as 256M x 16. Part of SK Hynix’s H5TC4G(6)3EFR series, it operates at a nominal 1.35V supply (VDD = VDDQ = 1.35V +0.100 / -0.067V) and remains backward compatible with 1.5V DDR3 environments, making it well suited to main-memory applications that demand large density, high bandwidth, and reduced power consumption. The internal data paths are pipelined and 8-bit prefetched for high bandwidth. The “-RD” speed grade corresponds to a DDR3-1866 data rate at 13-13-13 timing, and the “A” suffix denotes a commercial temperature grade with normal power consumption. The device ships in a JEDEC-standard 96-ball FBGA package.

This part is a legacy / not-recommended-for-new-design (NRND) DDR3L device, making it a hard-to-find sourcing item for repair, sustainment, and legacy production programs. Pacific Component Xchange currently holds inventory available for quote.
