Engineering Selection Recommendations

Active Status Substitutes (Recommended for New Designs):

LM2902KAVQDR, LM2902KAVQDRQ1, and LM2902KVQDRQ1 are classified as Active status and are suitable for new design implementations. These devices are manufactured by Texas Instruments and carry AEC-Q100 automotive qualification. LM2902KAVQDRQ1 and LM2902KVQDRQ1 provide enhanced current output capability of 60 mA per channel compared to the main part's 10 mA specification. All three active substitutes are RoHS3 compliant with MSL rating of 1 (Unlimited).

Last Time Buy Status Substitutes (Transition Planning Required):

LM2902DRG3, LM2902KNSR, and LM2902KVQDRG4 are classified as Last Time Buy status. These devices remain available but with limited future supply. Designs currently utilizing these parts should transition to Active status alternatives. All three maintain RoHS3 compliance and MSL 1 rating.

Obsolete Status Substitutes (Not Recommended for New Designs):

LM2902D, LM2902DR, LM2902KDR, and LM2902KVQDR are classified as Obsolete status. LM2902D from onsemi is additionally noted as RoHS non-compliant. These parts should not be selected for new designs. Existing designs using these components require transition planning to Active status alternatives.

Compliance Considerations:

All recommended substitutes maintain RoHS3 compliance and MSL 1 (Unlimited) rating, ensuring compatibility with environmental and moisture sensitivity requirements. LM2902KAVQDR, LM2902KAVQDRQ1, and LM2902KVQDRQ1 carry AEC-Q100 automotive qualification, suitable for automotive applications.

Package Compatibility Note:

LM2902KNSR utilizes a 14-SO package with 5.30mm width, differing from the standard 14-SOIC (0.154", 3.90mm) package. Physical board layout verification is required if this substitute is selected.

Frequently Asked Questions (FAQ)

Q: Can LM2902KAVQDRQ1 directly replace LP2902M/NOPB in existing designs?

A: LM2902KAVQDRQ1 is electrically compatible with LP2902M/NOPB. Both devices feature 4 circuits in a 14-SOIC package with identical minimum supply voltage (3 V). LM2902KAVQDRQ1 provides enhanced performance with higher slew rate (0.5 V/µs vs. 0.05 V/µs), greater gain bandwidth product (1.2 MHz vs. 100 kHz), and higher output current capability (60 mA vs. 10 mA per channel). Maximum supply voltage extends to 32 V compared to 26 V. Operating temperature range extends to 125°C. No circuit modifications are required for direct substitution.

Q: What is the difference between LM2902KAVQDR and LM2902KAVQDRQ1?

A: Both devices are manufactured by Texas Instruments with identical electrical specifications. The primary difference is maximum supply voltage: LM2902KAVQDR supports 30 V maximum while LM2902KAVQDRQ1 supports 32 V maximum. Additionally, LM2902KAVQDRQ1 provides 60 mA output current per channel compared to 30 mA for LM2902KAVQDR. Both are Active status, AEC-Q100 qualified, and RoHS3 compliant.

Q: Why does LM2902D show RoHS non-compliant status?

A: LM2902D from onsemi is classified as RoHS non-compliant and Obsolete status. This device should not be selected for new designs or applications requiring RoHS compliance. Active status alternatives such as LM2902KAVQDRQ1 provide equivalent functionality with full RoHS3 compliance.

Q: Is the package difference between LM2902KNSR and other substitutes significant?

A: LM2902KNSR uses a 14-SO package with 5.30mm width, while LP2902M/NOPB and most substitutes use 14-SOIC with 3.90mm width. This represents a physical size difference that affects printed circuit board layout and component placement. Existing board designs may require modification to accommodate LM2902KNSR. For designs without layout constraints, this substitute is functionally compatible.

Q: Which substitute offers the best performance improvement over LP2902M/NOPB?

A: LM2902KAVQDRQ1 and LM2902KVQDRQ1 provide the most significant performance enhancements. Both offer 12-fold increase in gain bandwidth product (1.2 MHz vs. 100 kHz), 10-fold increase in slew rate (0.5 V/µs vs. 0.05 V/µs), and 6-fold increase in output current capability (60 mA vs. 10 mA per channel). Operating temperature range extends from 85°C to 125°C. Both devices are Active status with AEC-Q100 qualification.

Q: Are all substitute parts available in the same packaging options as LP2902M/NOPB?

A: Most substitutes are available in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® packaging. LP2902M/NOPB is supplied in Tube packaging. Packaging format differences do not affect electrical compatibility but may impact procurement and handling procedures. Verify packaging availability with component suppliers for specific application requirements.

Q: What is the significance of AEC-Q100 qualification on certain substitutes?

A: AEC-Q100 qualification indicates the device meets automotive industry reliability and quality standards. LM2902KAVQDR, LM2902KAVQDRQ1, and LM2902KVQDRQ1 carry this qualification, making them suitable for automotive applications requiring enhanced reliability assurance. Non-qualified devices may be used in non-automotive applications where automotive-grade reliability is not required.

Q: Can substitutes with higher supply voltage ratings be used in circuits designed for 26 V maximum?

A: Yes. Substitutes with higher maximum supply voltage ratings (such as 30 V or 32 V) are fully compatible with circuits designed for 26 V operation. The higher rating provides additional design margin and flexibility for future applications. No circuit modifications are required.
