Component comparison · Last verified 2026-08-18
MT40A512M8SA-062E:F and MT40A512M8SA-075:F are 4Gb, 1.2V DDR4 x8 components in the same 78-ball TFBGA body, but they target different speed bins and sourcing states. The -062E code is listed at 3200MT/s and CL22 as Obsolete, while the -075 code is listed at 2666MT/s and CL19 with End of Life status.

Key differences
The x8 device speed grade changes the controller timing target
Micron lists MT40A512M8SA-062E:F at a 1600MHz clock, 3200MT/s transfer rate and CL22, while MT40A512M8SA-075:F is listed at 1333MHz, 2666MT/s and CL19. Those values define different DDR4 x8 catalog speed bins; the lower CL number on the -075 code is not proof of lower absolute latency or direct interchangeability without the complete timing tables and the controller's supported operating point.
Obsolete and End of Life require different sourcing evidence
Micron lists the -062E ordering code as Obsolete and the -075 ordering code as End of Life. Neither should be represented as a current Production design-in. Confirm factory orderability, last-time-buy or remaining-life status, date-code and lot traceability, storage history, packing integrity and an approved replacement path before procurement.
Can these parts be interchanged?
The two order codes share the same catalog-level 4Gb DDR4 x8, 1.2V, 512Mb x8 configuration, 78-ball TFBGA body, 7.50 x 11.00 x 1.20 mm dimensions, commercial temperature range and packing quantities. That overlap does not prove drop-in compatibility across speed bins. Verify the controlling data-sheet revision, exact ball assignment and land pattern, controller timing mode, supported clock and transfer rate, CAS and other timing parameters, signal integrity, power-up behavior, firmware initialization, thermal margin and current Micron orderability before qualification or substitution.

MT40A512M8SA-062E:F vs MT40A512M8SA-075:F FAQ
What is the main difference between MT40A512M8SA-062E:F and MT40A512M8SA-075:F?
Micron lists the -062E code at 1600MHz, 3200MT/s and CL22, while the -075 code is listed at 1333MHz, 2666MT/s and CL19. Their Micron catalog lifecycle labels also differ: Obsolete versus End of Life.
Are MT40A512M8SA-062E:F and MT40A512M8SA-075:F drop-in replacements?
Do not assume so. They share density, width, voltage and the catalog package outline, but they are different speed grades. Review the exact timing tables, controller configuration, ball map, land pattern, power and firmware requirements before substitution.
Which part has the higher listed DDR4 transfer rate?
Micron lists MT40A512M8SA-062E:F at 3200MT/s and MT40A512M8SA-075:F at 2666MT/s. A higher speed-bin rating does not remove the need to validate every timing parameter at the intended controller operating point.
Is either ordering code listed as Production?
No. Micron lists MT40A512M8SA-062E:F as Obsolete and MT40A512M8SA-075:F as End of Life in the checked catalogs. Reconfirm live factory support and the complete ordering code before sourcing.
What must be checked before changing between the -062E and -075 x8 speed grades?
Check the revision-controlled data sheet, supported clock and transfer rate, CAS and other timing limits, controller mode, signal integrity, package drawing and ball assignment, PCB footprint, power-up sequence, firmware setup, lifecycle, traceability and current orderability.
