삼성 K4A8G165WB-BCRC 8Gb DDR4 SDRAM: 사양, 설계 가이드 및 대체품

What is the Samsung K4A8G165WB-BCRC and what are its key verified specifications?

The Samsung K4A8G165WB-BCRC is an 8Gb DDR4 SDRAM organized as 512M x 16, operating at a data rate of 2400 Mbps (PC4-19200) with a 1.2V power supply. It comes in a 96-ball FBGA package and is currently in active lifecycle status with 99,999 units in stock at XAIPART (as of 2026-08-21). This memory device is designed for servers, industrial PCs, network equipment, automotive systems, and high-performance embedded computing.

Key verified specifications include: memory type DDR4 SDRAM, memory size 8 Gb, organization 512M x 16, data rate 2400 Mbps, supply voltage 1.2 V, package FBGA-96, clock frequency 1200 MHz, and RoHS compliance. The device supports auto-refresh and self-refresh modes, and includes on-die termination (ODT) for signal integrity.

How to select and design in the K4A8G165WB-BCRC?

When selecting the K4A8G165WB-BCRC for your design, verify that your memory controller supports DDR4 at 2400 Mbps with a x16 interface. The 1.2V supply voltage is standard for DDR4, but ensure your power design can deliver stable 1.2V with adequate decoupling. The FBGA-96 package requires careful PCB layout; follow the recommended footprint and routing guidelines from the datasheet to maintain signal integrity at 2400 Mbps.

Key design considerations include: place decoupling capacitors (0.1µF and 1µF) near each VDD and VDDQ pin, use a solid ground plane, and match trace lengths for DQ, DQS, and address/command signals. The device supports on-die termination (ODT) which can be configured via mode registers to improve signal quality. Ensure the reference voltage VREFCA is properly generated and filtered.

For power sequencing, apply VDD and VDDQ simultaneously and follow the DDR4 JEDEC power-up sequence. The reset pin (RESET_n) must be held low during power-up and released after supplies are stable. The clock enable (CKE) must be high for normal operation.

Thermal management is critical; the 96-ball FBGA package has a thermal resistance that should be considered. For high-density modules, use multiple devices with appropriate address and bank decoding.

Always refer to the official Samsung datasheet for detailed timing parameters and AC/DC characteristics. [DATA_NEEDED: operating temperature range] and [DATA_NEEDED: CAS latency] are not provided in the verified data and must be obtained from the datasheet.

What are the drop-in alternatives for the K4A8G165WB-BCRC?

Based on verified data, the following components are identified as alternatives. Note that not all are pin-compatible; verify pinout and timing before substitution.

Summary: The MT41K512M16HA-125 and H5AN8G16NCJR-VKC are cross-brand alternatives with similar capacity and speed, but their pinout and electrical specifications must be verified against your design. The K4A8G165WB-BCPB and K4A8G165WB-BCTD are Samsung parts that may be pin-compatible, but their exact specifications are not provided in the verified data.

Industry Insight: Market position, lifecycle, and supply situation

The K4A8G165WB-BCRC is in active lifecycle status, indicating it is currently in production and available for new designs. As of 2026-08-21, XAIPART lists 99,999 units in stock, suggesting healthy supply. Pricing tiers range from $60 for single units to $35 for quantities of 1000 or more, reflecting volume discounts.

Market position: Samsung is a leading DRAM manufacturer, and this 8Gb DDR4 device is widely used in servers, industrial, and automotive applications. The 2400 Mbps data rate is a mainstream speed grade for DDR4, making it a popular choice for cost-sensitive designs.

Supply situation: With 99,999 units in stock, immediate availability is strong. However, the global DRAM market can be volatile; buyers should monitor lead times and consider securing inventory for long-term projects. [DATA_NEEDED: market share data] and [DATA_NEEDED: specific supply chain risks] are not provided.

Trends & Outlook: What should buyers watch?

DDR4 remains a dominant memory technology, especially for industrial and automotive applications where long lifecycles are common. The K4A8G165WB-BCRC's 1.2V operation and 2400 Mbps data rate align with the industry trend toward lower power and higher bandwidth.

Buyers should watch for: 1) The transition to DDR5, which may affect DDR4 pricing and availability over time. 2) Potential shortages due to increased demand from AI and edge computing. 3) The availability of pin-compatible alternatives from other manufacturers to mitigate supply risks.

The verified data shows that the K4A8G165WB-BCRC is currently in active status with ample stock, making it a reliable choice for designs requiring 8Gb DDR4 at 2400 Mbps.
