Texas Instruments LM2902KNSR
LM2902KNSR variants from Texas Instruments
LM2902KNSR Overview
What changes between part numbers, and what to check before you lock the BOM — Operational Amplifiers, Instrumentation Amplifiers and Buffer Amplifiers.
LM2902KNSR is a Texas Instruments order-code family — not a single orderable MPN. This page lists 2 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: 14-SOIC (0.209", 5.30mm Width) | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 125°C (TA) | Current Supply: 1.4mA (x4 Channels) | Supplier Device Package: 14-SO | Number of Circuits: 4 Other listed variants describe: Quad Op Amp, 1.2MHz BW, 13V, 4-Ch, SOP, -40 to 125C.
Across listed variants, watch these parameters: packages: 14-SOIC (0.209", 5.30mm Width).
Example MPNs: LM2902KNSRG4, LM2902KNSR.
Key Features
- Footprint / package: 14-SOIC (0.209", 5.30mm Width)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.
Target Applications
- Operational Amplifiers, Instrumentation Amplifiers and Buffer Amplifiers — 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 2 LM2902KNSR part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.

Ordering Code Differences
How suffixes on LM2902KNSR map to package, grade, and reel options.
LM2902KNSR 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: G4.
Full MPN examples: LM2902KNSRG4.
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 LM2902KNSR Operational Amplifiers, Instrumentation Amplifiers and Buffer Amplifiers
Match the footprint first
Packages here: 14-SOIC (0.209", 5.30mm Width). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For LM2902KNSR, 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 "LM2902KNSR" — include the full suffix (e.g. G4). RFQ with reel/tube preference and required date code.
