LM2931Z Overview
What changes between part numbers, and what to check before you lock the BOM — Integrated Circuits (ICs).
Key Features
- Footprint / package: TO-226-3, TO-92-3 Long Body (Formed Leads)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.
- 3 distinct suffix patternsExamples: 5.0RPG, 5.0G, 5.0RAG. 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 3 LM2931Z 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 |
|---|---|---|---|---|---|---|---|
| LM2931Z-5.0RPG | Package: TO-226-3, TO-92-3 Long Body (Formed Leads) | Mounting Type: Through Hole | Operating Temperature: -40°C ~ 125°C | Output Type: Fixed | Voltage Input Max: 40V | Supplier Device Package: TO-92 (TO-226) | TO-226-3, TO-92-3 Long Body (Formed Leads) | onsemi | Active | Compliant | In Stock | |

Ordering Code Differences
How suffixes on LM2931Z map to package, grade, and reel options.
How to Choose the Right LM2931Z Integrated Circuits (ICs)
Match the footprint first
Packages here: TO-226-3, TO-92-3 Long Body (Formed Leads). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For LM2931Z, 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 "LM2931Z" — include the full suffix (e.g. 5.0RPG, 5.0G, 5.0RAG). RFQ with reel/tube preference and required date code.
