Microchip Technology 24LC04
24LC04 variants from Microchip Technology
24LC04 Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Footprint / package: 8-VFDFN Exposed Pad, 8-SOIC (0.154", 3.90mm Width), 8-TSSOP (0.173", 4.40mm Width)Land 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.
- 12 distinct suffix patternsExamples: B-E/MS, B-I/ST, B/P, B/SN, BT-E/MS (+7 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 24LC04 Microcontrollers
Match the footprint first
Packages here: 8-VFDFN Exposed Pad, 8-SOIC (0.154", 3.90mm Width), 8-TSSOP (0.173", 4.40mm Width). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For 24LC04, 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 "24LC04" — include the full suffix (e.g. B-E/MS, B-I/ST, B/P). RFQ with reel/tube preference and required date code.
