Microchip Technology DSPIC33FJ
DSPIC33FJ variants from Microchip Technology
DSPIC33FJ Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Footprint / package: 20-SOIC (0.295", 7.50mm Width)Single package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 13 distinct suffix patternsExamples: 128GP306-I/PT, 128GP706A-I/PT, 128GP802-E/MM, 128MC204-I/PT, 12MC201-I/SO (+8 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Microcontrollers — 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 DSPIC33FJ Microcontrollers
Match the footprint first
Packages here: 20-SOIC (0.295", 7.50mm Width). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For DSPIC33FJ, 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 "DSPIC33FJ" — include the full suffix (e.g. 128GP306-I/PT, 128GP706A-I/PT, 128GP802-E/MM). RFQ with reel/tube preference and required date code.
