DDR3 SDRAM Full Cross-reference Table

Selection Notes

• Density and organization — match organization to your memory controller.
• Speed grade — higher grades are generally downward compatible.
• Voltage — DDR3 1.5V, DDR3L 1.35V, DDR4 1.2V, LPDDR4/X 1.8/1.1V.
• Temperature — commercial 0~85C, industrial -40~85C.
• Confirmation — cross-brand replacement requires matching density, organization, speed, voltage and die; confirm with our FAE before ramp-up.

Micron DDR3-1866 / DDR3-2133 Full Cross-reference (29 parts)

Compiled from the complete Micron DDR3 SDRAM part catalog (1/2/4/8Gb, x8/x16, 933MHz=1866MT/s and 1066MHz=2133MT/s): 29 part numbers including commercial, industrial IT/XIT, automotive AAT/AUT and enhanced-industrial AIT temperature grades, mapped to 11 HGCHIPS specifications. Mapping is a specification-to-specification comparison; production status must be confirmed part by part with our FAE. Parts marked "FAE review required" show Contact Sales status in the Micron catalog. Voltage convention: the Micron prefix carries the voltage — MT41K = 1.35V (DDR3L), MT41J = 1.5V (DDR3). Samsung / SK Hynix 1.35V parts include an L in the HGCHIPS part number (e.g. HGD32G16L18); the Micron family does not. Always confirm voltage in the table below.

Ramp-up notes

• Lock the mapping on density + organization + speed + voltage first; only step up the temperature grade when the platform truly requires it (automotive and industrial grades carry a clear price premium).
• 1866MT/s (933MHz) is downward compatible with 1600MT/s platforms, and 2133MT/s (1066MHz) likewise; confirm platform speed in the controller datasheet.
• Cross-check pin-out and register maps with our FAE and complete small-batch validation before ramp-up.
