H5TQ4G83EFR-RDA – DDR3 SDRAM – SK Hynix

The SK Hynix H5TQ4G83EFR-RDA is a 4Gb (512M x8) DDR3 SDRAM in a 78-ball FBGA package, operating at 1.5V. This hard-to-find, end-of-life memory device is available for RFQ from Pacific Component Xchange.

The SK Hynix H5TQ4G83EFR-RDA is a 4-gigabit (4Gb) Double Data Rate 3 (DDR3) synchronous DRAM organized as 512M x8. Built for main-memory and embedded applications that demand large density and high bandwidth, this device packs eight internal banks into a compact 78-ball Fine-Pitch Ball Grid Array (FBGA) and operates from a 1.5V supply (VDD = VDDQ = 1.5V). It is part of SK Hynix’s lead-free and halogen-free H5TQ4G83EFR family of 4Gb DDR3 components.

As an end-of-life DDR3 component, the H5TQ4G83EFR-RDA is increasingly difficult to source through authorized channels, making it a prime candidate for long-lifecycle and legacy system support through an independent distributor. Pacific Component Xchange currently holds inventory and accepts requests for quote.
