Micron Technology Inc. MT46V
MT46V variants from Micron Technology Inc.
MT46V Overview
What changes between part numbers, and what to check before you lock the BOM — general-purpose circuits.
Key Features
- Footprint / package: 66-TSSOP (0.400", 10.16mm Width), 60-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.
- 4 distinct suffix patternsExamples: 16M16P-5B:M, 32M16P-5B:J, 64M8CY-5B:J, 64M8P-5B:J. 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
Ordering Variants
Compare 4 MT46V part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.

How suffixes on MT46V map to package, grade, and reel options.
How to Choose the Right MT46V Variant
Match the footprint first
Packages here: 66-TSSOP (0.400", 10.16mm Width), 60-TFBGA. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For MT46V, 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 "MT46V" — include the full suffix (e.g. 16M16P-5B:M, 32M16P-5B:J, 64M8CY-5B:J). RFQ with reel/tube preference and required date code.
