Texas Instruments LM2673T
LM2673T variants from Texas Instruments
LM2673T Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Footprint / package: TO-220-7 Formed LeadsSingle 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: 5.0/NOPB, ADJ/NOPB, 12/NOPB. 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
Ordering Variants
Compare 3 LM2673T 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 |
|---|---|---|---|---|---|---|---|
| LM2673T-5.0/NOPB | 5V DC-DC Step Down Conv, 3A, 8-40V In, TO-220 | - | Texas Instruments | Active | Compliant | In Stock | |
| LM2673T-ADJ/NOPB | 3A Adj Buck Converter, 8-40V In, 1.2-37V Out, TO-220-7 | - | Texas Instruments | Active | Compliant | In Stock | |
| LM2673T-12/NOPB | Package: TO-220-7 Formed Leads | Mounting Type: Through Hole | Number of Outputs: 1 | Operating Temperature: -40°C ~ 125°C (TJ) | TO-220-7 Formed Leads | Texas Instruments | Active | Compliant | In Stock |

How to Choose the Right LM2673T Microcontrollers
Match the footprint first
Packages here: TO-220-7 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 LM2673T, 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 "LM2673T" — include the full suffix (e.g. 5.0/NOPB, ADJ/NOPB, 12/NOPB). RFQ with reel/tube preference and required date code.
