Frequently Asked Questions

What is the difference between MTC20C2085S1TC48BA1 and MTC20C2085S1TC48BA1R?

MTC20C2085S1TC48BA1R is the Renesas component variant while MTC20C2085S1TC48BA1 is the standard base revision. Electrical specifications are identical — the R suffix indicates the component vendor.

What is the difference between MTC20C2085S1TC48BA1 and MTC20C2085S1EC48BA1?

MTC20C2085S1TC48BA1 is a 262-pin SoDIMM (TC = SoDIMM form factor) while MTC20C2085S1EC48BA1 is a 288-pin DIMM (EC = standard DIMM). Both are 32GB DDR5-4800 ECC UDIMM 2Rx8 in different form factors.

Is ECC SoDIMM compatible with non-ECC SoDIMM slots?

ECC SoDIMMs may operate in non-ECC slots with ECC disabled depending on platform support. Verify your platform's ECC SoDIMM compatibility before installation.

The Micron MTC20C2085S1TC48BA1 delivers 32GB DDR5-4800 ECC unbuffered memory in 262-pin SoDIMM 2Rx8 configuration — the standard BA1 base revision for laptops workstations and embedded platforms supporting ECC DDR5 SO-DIMM.
