Engineering Selection Recommendations

Primary Recommendation - Active Status Parts:

For new designs and ongoing production requiring immediate component availability, the following Texas Instruments parts are recommended as direct substitutes:

LM2902KAVQPWRQ1 (Active status, AEC-Q100 qualified): Provides automotive-grade qualification with identical electrical specifications to the LM2902PWR. Supply voltage maximum of 32 V exceeds the original specification. Output current of 60 mA per channel provides enhanced drive capability. Slew rate of 0.5 V/µs represents improved performance over the original 0.3 V/µs specification.
LM2902KAVQPWREP (Active status): Extends operating temperature range to -55°C to 125°C and supply voltage to 32 V. Output current capability increased to 60 mA per channel. Suitable for applications requiring extended environmental performance.
LM2902KAVMPWREP (Active status): Identical electrical performance to LM2902KAVQPWREP with active product status and full availability.

Secondary Recommendation - Last Time Buy Status:

LM2902KAVQPWRG4Q1 (Last Time Buy, AEC-Q100 qualified): Maintains identical electrical specifications to primary recommendations with automotive qualification. Suitable for applications with extended production timelines.

Alternative Consideration - onsemi Parts:

LM2902DTBR2G (Active status): Provides active product status with 14-TSSOP package compatibility. Gain bandwidth product of 1 MHz represents a reduction from the 1.2 MHz specification. Input bias current of 90 nA exceeds the original 20 nA specification. Output current of 40 mA per channel exceeds the original 30 mA requirement. Supply voltage range extends to 32 V maximum. Operating temperature range of -40°C to 105°C is narrower than the original specification.

Compliance Verification:

All recommended substitute parts maintain RoHS3 compliance, MSL Level 1 (Unlimited), and REACH unaffected status consistent with the original LM2902PWR specification.

Frequently Asked Questions (FAQ)

Q: Can the LM2902KAVQPWRQ1 be used as a direct replacement for the LM2902PWR in existing designs?

A: The LM2902KAVQPWRQ1 is electrically compatible with the LM2902PWR. Both devices feature identical gain bandwidth product (1.2 MHz), input bias current (20 nA), input offset voltage (3 mV), and output current per channel (30 mA minimum). The 14-TSSOP package is identical. The LM2902KAVQPWRQ1 provides enhanced slew rate (0.5 V/µs versus 0.3 V/µs) and extended supply voltage range (32 V maximum versus 26 V maximum), representing performance improvements. Pin-for-pin compatibility is maintained.

Q: What is the difference between LM2902KAVQPWR and LM2902KAVQPWREP?

A: Both parts are manufactured by Texas Instruments and share identical electrical specifications including slew rate (0.5 V/µs), gain bandwidth product (1.2 MHz), input bias current (20 nA), and input offset voltage (3 mV). The primary differences are: LM2902KAVQPWR has a maximum supply voltage of 30 V and operating temperature range of -40°C to 125°C; LM2902KAVQPWREP has a maximum supply voltage of 32 V and extended operating temperature range of -55°C to 125°C. The LM2902KAVQPWREP provides enhanced output current capability (60 mA per channel versus 30 mA).

Q: Is the onsemi LM2902DTBR2G suitable as a substitute?

A: The onsemi LM2902DTBR2G maintains 14-TSSOP package compatibility and active product status. However, electrical differences exist: gain bandwidth product is 1 MHz (versus 1.2 MHz), input bias current is 90 nA (versus 20 nA), and input offset voltage is 2 mV (versus 3 mV). The part provides superior output current capability (40 mA per channel versus 30 mA) and extended supply voltage range (32 V maximum). Operating temperature range is -40°C to 105°C. Substitution is feasible for applications where the reduced gain bandwidth product and increased input bias current are acceptable.

Q: What packaging options are available for LM2902 substitutes?

A: All recommended substitute parts maintain the 14-TSSOP (0.173", 4.40mm Width) surface mount package identical to the LM2902PWR. Packaging formats vary by part number: some are supplied in Tape & Reel (TR), others in Cut Tape (CT) & Digi-Reel®, and some in Tube format. Selection should be based on production volume and assembly process requirements.

Q: Are the Texas Instruments LM2902 variants automotive qualified?

A: The LM2902KAVQPWR, LM2902KAVQPWRG4Q1, and LM2902KAVQPWRQ1 are AEC-Q100 qualified automotive-grade parts. These variants are suitable for automotive applications requiring qualification documentation. Non-automotive variants (LM2902KAVQPWREP and LM2902KAVMPWREP) are not designated with automotive qualification but maintain identical electrical specifications.

Q: What is the significance of "Last Time Buy" product status?

A: Parts designated as "Last Time Buy" indicate that the manufacturer has announced end-of-life for that specific part number. Existing inventory is available for purchase, but no future production is planned. The LM2902KPWR and LM2902KAVQPWRG4Q1 carry this designation. These parts remain suitable for use but should not be selected for new long-term production programs. Active status parts are recommended for designs with extended production timelines.

Q: How do the Rohm Semiconductor LM2902 variants compare to Texas Instruments versions?

A: Rohm Semiconductor manufactures the LM2902KPWR, LM2902KVQPWR, and the original LM2902PWR. All three Rohm variants share identical electrical specifications: slew rate of 0.3 V/µs, gain bandwidth product of 1.2 MHz, input bias current of 20 nA, and input offset voltage of 3 mV. The LM2902PWR and LM2902KVQPWR are classified as obsolete or not for new designs. The LM2902KPWR carries "Last Time Buy" status. Texas Instruments variants provide enhanced slew rate (0.5 V/µs) and extended supply voltage ranges, with active product status available.

Q: Can supply voltage range differences affect circuit performance?

A: Supply voltage range differences between substitute parts do not affect circuit performance within the overlapping voltage range. The LM2902PWR operates from 3 V to 26 V. Substitute parts with extended maximum ratings (30 V or 32 V) provide additional design margin and flexibility for applications requiring higher supply voltages. Minimum supply voltage remains 3 V across all variants, ensuring compatibility with low-voltage applications.
