Substitute Part Grouping Explanation

Substitution of the LP2902MX/NOPB is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

Number of circuits (must be 4)
Package type (14-SOIC form factor)
Supply voltage range (minimum 3 V, maximum ≥ 26 V)
Operating temperature range (must support -40°C to 85°C minimum)
Amplifier type (General Purpose)

Mechanical Compatibility Criteria:

Surface mount mounting type
14-SOIC package footprint (0.154", 3.90mm width)

Performance Considerations: Substitute parts may exhibit different slew rates, gain bandwidth products, input bias currents, and output current capabilities. These differences do not prevent substitution but indicate performance variations that must be evaluated against application requirements.

Compliance Considerations: RoHS3 compliance and MSL rating are maintained across all substitute options. Product status (Active, Last Time Buy, or Obsolete) affects long-term availability but does not prevent functional substitution.

Engineering Selection Recommendations

Direct Substitutes (Identical Electrical and Mechanical Specifications):

LP2902DR is the primary direct substitute for LP2902MX/NOPB. Both devices share identical electrical specifications including 0.05 V/µs slew rate, 100 kHz gain bandwidth product, 2 nA input bias current, and 2 mV input offset voltage. The primary difference is packaging format: LP2902DR is supplied in Cut Tape (CT) & Digi-Reel® format versus Tape & Reel (TR) for the LP2902MX/NOPB. Both maintain Active product status and ROHS3 compliance. LP2902DR supports a maximum supply voltage of 32 V compared to 26 V for the LP2902MX/NOPB, providing enhanced voltage headroom capability.

Performance-Enhanced Substitutes (Higher Bandwidth and Output Current):

LM2902KAVQDRQ1 and LM2902KAVQDR are Texas Instruments devices offering enhanced performance specifications. These parts feature 1.2 MHz gain bandwidth product (12× higher than the main part), 0.5 V/µs slew rate (10× higher), and 30 mA output current per channel (3× higher). LM2902KAVQDRQ1 provides 60 mA output current per channel. Both maintain Active product status, ROHS3 compliance, and AEC-Q100 automotive qualification. Operating temperature extends to 125°C. Supply voltage range extends to 30 V (LM2902KAVQDR) or 32 V (LM2902KAVQDRQ1).

Alternative Substitutes with Extended Temperature Range:

Package Variant:

LM2902KNSR is a Last Time Buy device with identical electrical specifications to other LM2902 variants but features a larger 14-SO package (0.209", 5.30mm width) instead of the standard 14-SOIC (0.154", 3.90mm width). This package variant is not pin-compatible with the LP2902MX/NOPB footprint.

Frequently Asked Questions (FAQ)

Q: Can LP2902DR be used as a direct replacement for LP2902MX/NOPB?

A: Yes. LP2902DR is electrically and mechanically compatible with LP2902MX/NOPB. Both devices share identical slew rate (0.05 V/µs), gain bandwidth product (100 kHz), input bias current (2 nA), and input offset voltage (2 mV). The primary difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). LP2902DR supports a higher maximum supply voltage (32 V versus 26 V), providing additional design margin.

Q: What is the difference between LP2902MX/NOPB and LM2902KAVQDRQ1?

A: LM2902KAVQDRQ1 offers significantly enhanced performance specifications. It provides 1.2 MHz gain bandwidth product (versus 100 kHz), 0.5 V/µs slew rate (versus 0.05 V/µs), and 60 mA output current per channel (versus 10 mA). Operating temperature extends to 125°C (versus 85°C). Supply voltage range extends to 32 V (versus 26 V). LM2902KAVQDRQ1 includes AEC-Q100 automotive qualification. These enhancements make it suitable for higher-speed applications requiring greater output drive capability.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed are RoHS3 compliant except LM2902D (onsemi), which carries RoHS non-compliant status. For applications requiring RoHS3 compliance, LM2902D must be excluded from consideration.

Q: Can LM2902KNSR be used in place of LP2902MX/NOPB?

A: LM2902KNSR is not suitable as a direct replacement. While electrically compatible, it features a larger 14-SO package (0.209", 5.30mm width) compared to the 14-SOIC package (0.154", 3.90mm width) of LP2902MX/NOPB. The different package footprint is not compatible with existing PCB layouts designed for the LP2902MX/NOPB.

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

A: Last Time Buy status indicates that the manufacturer has announced end-of-life for the product. Existing inventory is available for purchase, but no future production is planned. Parts with this status (LM2902DRG3, LM2902KNSR, LM2902KVQDRG4) should not be selected for new designs requiring long-term component availability.

Q: Which substitute offers the best performance for high-speed applications?

A: LM2902KAVQDRQ1 provides the highest performance specifications among all substitutes, featuring 1.2 MHz gain bandwidth product, 0.5 V/µs slew rate, and 60 mA output current per channel. This device is suitable for applications requiring faster signal processing and higher output drive capability while maintaining Active product status and ROHS3 compliance.

Q: Are there packaging format options available?

A: Yes. LP2902DR is available in Cut Tape (CT) & Digi-Reel® format, while LP2902MX/NOPB is supplied in Tape & Reel (TR) format. Both use identical 14-SOIC (0.154", 3.90mm) package footprints. LM2902KNSR uses a larger 14-SO (0.209", 5.30mm) package and is not footprint-compatible.

Q: What is the maximum supply voltage for each substitute?

A: LP2902MX/NOPB and LP2902DR support 26 V and 32 V maximum supply voltage respectively. LM2902KAVQDR supports 30 V. LM2902KAVQDRQ1 and LM2902DR support 32 V. LM2902DRG3, LM2902KDR, LM2902KNSR, and LM2902KVQDR support 26 V maximum. LM2902KVQDRG4 supports 30 V.

Q: Is automotive qualification available?

A: Yes. LM2902KAVQDR and LM2902KAVQDRQ1 include AEC-Q100 automotive qualification and are suitable for automotive applications. The main part LP2902MX/NOPB does not carry automotive qualification.
