Microchip Technology MCP1703T
MCP1703T variants from Microchip Technology
MCP1703T Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 9 distinct suffix patternsExamples: 3002E/CB, 3002E/DB, 3302E/CB, 3302E/DB, 3302E/MB (+4 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 MCP1703T Microcontrollers
Match the footprint first
Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.
Electrical headroom
Compare voltage and current columns in the variant table. For MCP1703T, 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 "MCP1703T" — include the full suffix (e.g. 3002E/CB, 3002E/DB, 3302E/CB). RFQ with reel/tube preference and required date code.
