MT41K256M16HA-125: 4Gbit DDR3L SDRAM Specs, Price, and Drop-In Alternatives

What is the MT41K256M16HA-125 and what are its key specs?

The MT41K256M16HA-125 is a 4Gbit DDR3L SDRAM from Micron Technology, organized as 256M x 16. It operates at 1.35V with a clock speed of 800 MHz (DDR3L-1600) and is housed in a 96-ball FBGA (9x14mm) package. This low-voltage memory reduces power consumption by up to 20% compared to standard 1.5V DDR3, making it ideal for laptops, embedded systems, networking equipment, and industrial PCs. As of 2026-08-21, XAIPART has 99,999 units in stock with pricing starting at $6.3636 per unit at quantities of 1000+.

Technical Guide: How to design in the MT41K256M16HA-125

When designing with the MT41K256M16HA-125, follow these guidelines based on verified specifications:

• Power supply: Provide a stable 1.35V core supply (VDD) and 1.35V I/O supply (VDDQ). Use 0.1uF and 1uF decoupling capacitors near the power pins to minimize noise.
• Signal integrity: The device supports on-die termination (ODT) and dynamic ODT. Use proper termination for address and control lines as recommended in the Micron datasheet.
• Timing: The CAS latency is 11 cycles, and the access time (tRCD) is 13.75 ns. Ensure your memory controller supports DDR3L-1600 timing.
• Refresh: The refresh interval is 7.8 us at 85C. Implement auto-refresh or self-refresh modes as needed.
• Layout: Follow the layout guidelines in the Micron datasheet to minimize signal integrity issues. The 96-ball FBGA package (9x14mm) is surface-mount and requires careful PCB design.

Alternatives & Comparison: Drop-in replacements for MT41K256M16HA-125

Based on verified data, the following components are drop-in alternatives. Always verify timing parameters before production use.

Summary: The MT41K256M16HA-125IT is the closest drop-in replacement with the same specs but extended industrial temperature range. The MT41K256M16TW-107AIT:P offers higher speed but operates at 1.5V, so verify compatibility with your power design.

Industry Insight: Market position and supply situation

The MT41K256M16HA-125 has a lifecycle status of active, indicating ongoing production and availability. As of 2026-08-21, XAIPART holds 99,999 units in stock, ensuring immediate availability for orders. The base price is $6.3636 at quantities of 1000+, with tiered pricing from $10.9091 (qty 1) down to $6.3636 (qty 1000+). This pricing reflects a mature product in the DDR3L segment, which remains relevant for industrial and embedded applications due to its low power and cost-effectiveness.

Trends & Outlook: What buyers should watch

As DDR3L memory continues to serve power-sensitive and cost-conscious designs, the MT41K256M16HA-125 remains a solid choice. Buyers should monitor the following:

• Supply stability: With active lifecycle status and substantial stock, supply is currently stable. However, as the industry shifts toward DDR4/DDR5, long-term availability may tighten. Plan your procurement accordingly.
• Industrial temperature variants: For harsh environments, consider the MT41K256M16HA-125IT with -40C to 95C operation. This variant is essential for automotive and industrial applications.
• Speed upgrades: The MT41K256M16TW-107AIT:P offers 1066 MHz speed but at 1.5V. Evaluate whether the higher bandwidth justifies the power trade-off.
• Cross-brand equivalents: The H5TQ4G63AFR-PBA from SK Hynix is a cross-brand alternative with the same density and speed. Verify timing parameters before substitution.
