Microchip Technology MIC5239
MIC5239 variants from Microchip Technology
MIC5239 Overview
What changes between part numbers, and what to check before you lock the BOM — Integrated Circuits (ICs).
Key Features
- Footprint / package: 8-SOIC (0.154", 3.90mm Width), 8-TSSOP, 8-MSOP (0.118", 3.00mm 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.
- 4 distinct suffix patternsExamples: 3.3YM-TR, 5.0YMM-TR, 3.0YS, 5.0YM-TR. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Integrated Circuits (ICs) — 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 MIC5239 part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Package Type | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|---|
| MIC5239-3.3YM-TR | Package: 8-SOIC (0.154", 3.90mm Width) | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 125°C | Output Type: Fixed | Voltage Input Max: 30V | Supplier Device Package: 8-SOIC | 8-SOIC (0.154", 3.90mm Width) | Microchip Technology | Active | Compliant | In Stock | |
| MIC5239-5.0YMM-TR | Package: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 125°C | Output Type: Fixed | Voltage Input Max: 30V | Supplier Device Package: 8-MSOP | 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) | Microchip Technology | Active | Compliant | In Stock | |

How to Choose the Right MIC5239 Integrated Circuits (ICs)
Match the footprint first
Packages here: 8-SOIC (0.154", 3.90mm Width), 8-TSSOP, 8-MSOP (0.118", 3.00mm Width). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For MIC5239, 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 "MIC5239" — include the full suffix (e.g. 3.3YM-TR, 5.0YMM-TR, 3.0YS). RFQ with reel/tube preference and required date code.
