Micron Technology Inc. MT40A
MT40A variants from Micron Technology Inc.
MT40A Overview
What changes between part numbers, and what to check before you lock the BOM — general-purpose circuits.
Key Features
- Footprint / package: 96-TFBGA, 78-TFBGALand pattern and thermal pad differ between these packages — run a quick footprint check before you swap variants.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 8 distinct suffix patternsExamples: 1G16RC-062E:B, 1G16TB-062E:F, 1G8SA-062E:R, 2G8JC-062E:E, 2G8VA-062E:B (+3 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- general-purpose circuits — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained

How to Choose the Right MT40A Variant
Match the footprint first
Packages here: 96-TFBGA, 78-TFBGA. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For MT40A, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "MT40A" — include the full suffix (e.g. 1G16RC-062E:B, 1G16TB-062E:F, 1G8SA-062E:R). RFQ with reel/tube preference and required date code.
