LP3972SQ variants from Texas Instruments
LP3972SQ Overview
What changes between part numbers, and what to check before you lock the BOM — Integrated Circuits (ICs).
LP3972SQ is a Texas Instruments order-code family — not a single orderable MPN. This page lists 7 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
Package: 40-WFQFN Exposed Pad | Mounting Type: Surface Mount | Supply Voltage: 2.7V ~ 5.5V | Operating Temperature: -40°C ~ 85°C Other listed variants describe: Advanced Application Processors to 40-Pin WQFN EP T/R; Power Management 40-Pin LLP EP T/R.
Across listed variants, watch these parameters: packages: 40-WFQFN Exposed Pad.
Suffix examples in this family: 5810/NOPB, E514/NOPB, 0514/NOPB, A413/NOPB, A514/NOPB, I414/NOPB, I514/NOPB. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.
Example MPNs: LP3972SQ-5810/NOPB, LP3972SQ-E514/NOPB, LP3972SQ-0514/NOPB, LP3972SQ-A413/NOPB, LP3972SQ-A514/NOPB, LP3972SQ-I414/NOPB.
Key Features
- Footprint / package: 40-WFQFN Exposed PadSingle 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.
- 7 distinct suffix patternsExamples: 5810/NOPB, E514/NOPB, 0514/NOPB, A413/NOPB, A514/NOPB (+2 more). 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 Code Differences
How suffixes on LP3972SQ map to package, grade, and reel options.
LP3972SQ uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: 5810/NOPB, E514/NOPB, 0514/NOPB, A413/NOPB, A514/NOPB, I414/NOPB, I514/NOPB.
Full MPN examples: LP3972SQ-5810/NOPB, LP3972SQ-E514/NOPB, LP3972SQ-0514/NOPB, LP3972SQ-A413/NOPB, LP3972SQ-A514/NOPB.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
How to Choose the Right LP3972SQ Integrated Circuits (ICs)
Match the footprint first
Packages here: 40-WFQFN Exposed Pad. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For LP3972SQ, 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 "LP3972SQ" — include the full suffix (e.g. 5810/NOPB, E514/NOPB, 0514/NOPB). RFQ with reel/tube preference and required date code.
