LM2902M/NOPB Equivalent & Substitute Parts
Part Overview
The LM2902M/NOPB is a general-purpose operational amplifier manufactured by Texas Instruments, featuring four independent circuits in a 14-SOIC surface-mount package. This LinCMOS™ series device operates across a wide supply voltage range of 3 V to 32 V and is designed for applications requiring low input bias current and moderate bandwidth performance. The part is currently in active production status with 2640 units in stock.
Substitute parts are necessary when the LM2902M/NOPB becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for compatible alternatives from different manufacturers. Several equivalent devices maintain functional compatibility while offering variations in electrical performance, packaging, and product lifecycle status.

Engineering Selection Recommendations
For Active Production Designs:
Select LM2902KAVQDRQ1 or LM2902KVQDRQ1 (Texas Instruments, Tape & Reel packaging) as primary substitutes. Both parts maintain active product status, offer AEC-Q100 automotive qualification, and provide 60 mA output current per channel—exceeding the original 40 mA specification. These devices support the full 32 V maximum supply voltage and operate across the extended -40°C to 125°C temperature range. RoHS3 compliance and REACH unaffected status are confirmed.
For Extended Temperature Applications:
LM2902KAVQDR (Texas Instruments, Tape & Reel) provides active status with automotive-grade qualification and operates to 125°C. Supply voltage maximum is 30 V, which accommodates most industrial applications. Output current is limited to 30 mA per channel.
For Cost-Optimized Designs with Lifecycle Flexibility:
LM2902KVQDRG4 and LM2902KNSR (Texas Instruments, Last Time Buy status) remain available in significant quantities. These parts are suitable for designs where extended product lifecycle is not critical. LM2902KNSR uses the wider 14-SO package (0.209" width) and should be verified for PCB layout compatibility.
For Obsolete Part Replacement:
When replacing discontinued LM2902M/NOPB units in legacy systems, LM2902DR (Rohm Semiconductor) offers the lowest input offset voltage (1 mV) and maintains 32 V maximum supply voltage. However, obsolete status requires inventory verification. LM2902D (onsemi) provides functional equivalence with 1.2 MHz bandwidth but is limited to 26 V maximum supply.
Packaging Considerations:
Standard 14-SOIC (0.154" width) packages are interchangeable. The 14-SO variant (0.209" width, used in LM2902KNSR and LM2902NSR) requires PCB footprint verification before substitution.
Frequently Asked Questions (FAQ)
Q: Can LM2902KAVQDRQ1 directly replace LM2902M/NOPB in existing designs?
A: Yes. Both devices feature four circuits in 14-SOIC packaging with identical pinouts. LM2902KAVQDRQ1 exceeds the original specifications in output current (60 mA vs. 40 mA) and operating temperature range (-40°C to 125°C vs. -40°C to 85°C). The higher gain bandwidth product (1.2 MHz vs. 1.0 MHz) and lower input bias current (20 nA vs. 45 nA) are compatible with designs specified for the original part. Verify supply voltage requirements do not exceed 32 V.
Q: What is the difference between LM2902KAVQDR and LM2902KAVQDRQ1?
A: Both are Texas Instruments active-status parts with identical electrical specifications. The primary difference is output current per channel: LM2902KAVQDR provides 30 mA, while LM2902KAVQDRQ1 provides 60 mA. Maximum supply voltage differs slightly (30 V vs. 32 V). Select LM2902KAVQDRQ1 for applications requiring higher output drive capability.
Q: Are Rohm Semiconductor LM2902 variants (LM2902DR, LM2902KDR, LM2902KVQDR) suitable for new designs?
A: These parts are obsolete and not recommended for new production designs. They remain available in limited quantities for legacy system support only. For new designs, select active-status alternatives from Texas Instruments: LM2902KAVQDR, LM2902KAVQDRQ1, or LM2902KVQDRQ1.
Q: What is the significance of "Last Time Buy" status for LM2902KNSR and LM2902KVQDRG4?
A: Last Time Buy status indicates these parts are in final production phases with limited availability. Existing inventory is available for purchase, but no future production is planned. These parts are suitable for designs with defined production windows but should not be selected for long-term production programs. Transition to active-status alternatives (LM2902KAVQDRQ1 or LM2902KVQDRQ1) for ongoing production.
Q: Does the 14-SO package (0.209" width) used in LM2902KNSR and LM2902NSR require different PCB footprints?
A: Yes. The 14-SO package is wider (0.209") than the standard 14-SOIC package (0.154"). PCB footprints are not interchangeable without layout modification. Verify footprint compatibility before selecting these parts as substitutes. Standard 14-SOIC variants are preferred for direct replacement.
Q: Are all substitute parts RoHS3 compliant?
A: No. LM2902D (onsemi) is RoHS non-compliant. All Texas Instruments variants (LM2902KAVQDR, LM2902KAVQDRQ1, LM2902KNSR, LM2902KVQDRG4, LM2902KVQDRQ1, LM2902NSR) and Rohm Semiconductor variants (LM2902DR, LM2902KDR, LM2902KVQDR) are RoHS3 compliant. For applications requiring RoHS compliance, exclude LM2902D from consideration.
Q: What is the minimum supply voltage for all substitute parts?
A: All substitute parts operate at a minimum supply voltage of 3 V, matching the original LM2902M/NOPB specification. Maximum supply voltage varies: 26 V (LM2902D, LM2902KDR, LM2902KNSR, LM2902KVQDR, LM2902NSR), 30 V (LM2902KAVQDR, LM2902KVQDRG4), or 32 V (LM2902DR, LM2902KAVQDRQ1, LM2902KVQDRQ1). Verify application supply voltage requirements against the selected substitute.
Q: Which substitute offers the best input offset voltage specification?
A: LM2902DR (Rohm Semiconductor) specifies 1 mV input offset voltage, the lowest among all alternatives. The original LM2902M/NOPB specifies 2 mV. Most other substitutes specify 3 mV. For precision applications requiring minimal offset voltage, LM2902DR is optimal, though obsolete status requires inventory confirmation.
Q: Are automotive-grade qualifications available in active-status substitutes?
A: Yes. LM2902KAVQDR, LM2902KAVQDRQ1, and LM2902KVQDRQ1 (all Texas Instruments) carry automotive-grade designation with AEC-Q100 qualification. These parts are suitable for automotive and industrial applications requiring formal qualification documentation.
