LP2902PWRE4 Equivalent & Substitute Parts

Part Overview

The LP2902PWRE4 is a general-purpose operational amplifier integrated circuit manufactured by Texas Instruments, configured as a 4-circuit device in a 14-TSSOP surface mount package. This part is classified as obsolete, though 1118 units remain in stock as new original inventory. The LP2902PWRE4 operates across a supply voltage range of 3V to 32V with an operating temperature range of -40°C to 85°C, making it suitable for low-power analog signal processing applications.

Due to its obsolete product status, component sourcing for new designs or production runs requires identification of active equivalent and substitute parts that maintain functional compatibility while meeting current manufacturing and supply chain requirements.

Substitute Part Grouping Explanation

Substitution of the LP2902PWRE4 is determined by strict compatibility across the following critical parameters:

Package Compatibility: All substitute parts must use the 14-TSSOP surface mount package with 0.173" width and 4.40mm dimensions to ensure PCB footprint compatibility without layout redesign.

Electrical Specifications: Substitute parts must operate within the voltage supply range of 3V to 32V minimum. The input offset voltage of 2mV and input bias current specifications define the precision class of the device. Slew rate and gain bandwidth product determine signal fidelity and frequency response characteristics.

Thermal Operating Range: The LP2902PWRE4 operates from -40°C to 85°C. Substitute parts with narrower temperature ranges (such as 0°C to 70°C) are functionally compatible for applications not requiring the full extended temperature specification.

Circuit Configuration: All substitutes must provide 4 independent operational amplifier circuits within a single package.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and MSL rating of 1 (Unlimited) to ensure manufacturing process compatibility.

Substitutes are grouped into two categories based on electrical performance characteristics: LP-series parts (LP2902PWR, LP324MT/NOPB, LP324MTX/NOPB) maintain the original LP2902PWRE4 electrical specifications, while LM-series and alternative manufacturer parts (LM2902MT/NOPB, LM2902MTX/NOPB, LM324MT/NOPB, LM324MTX/NOPB, AS324GTR-E1, BA10324AFV-E2, BA2902FV-E2) offer enhanced performance characteristics with active product status.

Engineering Selection Recommendations

Direct Electrical Equivalent (Preferred for Pin-Compatible Replacement):

LP2902PWR is the active production equivalent of LP2902PWRE4. Both parts share identical electrical specifications including 0.05V/µs slew rate, 100kHz gain bandwidth product, 2nA input bias current, and 85µA supply current per 4-channel configuration. The primary difference is packaging format: LP2902PWR is supplied in Tape & Reel format with 23,390 units in stock, compared to the obsolete LP2902PWRE4. This part maintains full backward compatibility and requires no circuit redesign.

Extended Temperature Range Equivalent:

LP324MT/NOPB and LP324MTX/NOPB provide identical electrical performance to the LP2902PWRE4 but with a narrower operating temperature range of 0°C to 70°C. These parts are suitable for applications not requiring the -40°C to 85°C extended range. LP324MTX/NOPB offers superior inventory availability with 21,068 units in stock.

Enhanced Performance Alternatives (Higher Bandwidth):

LM2902MT/NOPB and LM2902MTX/NOPB offer 10x higher gain bandwidth product (1MHz versus 100kHz) with increased output current capability (40mA versus 10mA per channel). These parts maintain the full -40°C to 85°C temperature range and are suitable for applications requiring faster signal processing. Supply current increases to 1.5mA per 4-channel configuration.

LM324MT/NOPB and LM324MTX/NOPB provide identical performance to the LM2902 series but with a restricted operating temperature range of 0°C to 70°C. LM324MTX/NOPB provides the highest inventory availability among all substitutes with 21,068 units in stock.

Alternative Manufacturer Options:

AS324GTR-E1 (Diodes Incorporated) and BA10324AFV-E2 / BA2902FV-E2 (Rohm Semiconductor) provide functional equivalence with 14-TSSOP or 14-LSSOP packaging. These parts maintain ROHS3 compliance and are suitable for applications where multi-source qualification is required. BA2902FV-E2 extends the operating temperature range to -40°C to 125°C, providing enhanced thermal performance for high-temperature applications.

Product Status Consideration:

All recommended substitute parts maintain active product status with Texas Instruments or qualified alternative manufacturers, ensuring long-term supply chain availability and manufacturing process stability. The LP2902PWRE4 obsolete status necessitates transition to one of these active alternatives for new production designs.

Frequently Asked Questions (FAQ)

Q: Can LP2902PWR directly replace LP2902PWRE4 in existing designs?

A: Yes. LP2902PWR is the active production equivalent with identical electrical specifications and 14-TSSOP package. The only difference is packaging format (Tape & Reel versus Reel). No circuit modifications are required.

Q: What is the difference between LP2902 and LM2902 series parts?

A: The LP2902 series maintains the original specifications with 0.05V/µs slew rate and 100kHz gain bandwidth product. The LM2902 series provides enhanced performance with 1MHz gain bandwidth product and 40mA output current per channel, at the cost of increased supply current (1.5mA versus 85µA). Both series are electrically compatible within the 14-TSSOP package.

Q: Are LM324 parts suitable replacements for LP2902PWRE4?

A: LM324 parts are functionally compatible but with a narrower operating temperature range (0°C to 70°C versus -40°C to 85°C). For applications operating within 0°C to 70°C, LM324 parts provide equivalent performance. For extended temperature applications, LP2902PWR or LM2902 series are required.

Q: What packaging formats are available for substitute parts?

A: Substitute parts are available in Tape & Reel (TR), Tube, and Cut Tape & Digi-Reel formats. All maintain the 14-TSSOP surface mount package footprint. Packaging format selection depends on production volume and assembly equipment compatibility, not electrical performance.

Q: Can Rohm Semiconductor BA10324AFV-E2 or BA2902FV-E2 replace LP2902PWRE4?

A: Yes, with package consideration. BA10324AFV-E2 and BA2902FV-E2 use 14-LSSOP packaging, which is mechanically compatible with 14-TSSOP footprints. Both parts provide enhanced slew rate (0.2V/µs) and higher gain bandwidth product (500kHz). BA2902FV-E2 extends operating temperature to -40°C to 125°C. Verify PCB layout compatibility before implementation.

Q: What is the inventory status of substitute parts?

A: LP2902PWR offers the highest inventory among direct equivalents with 23,390 units. LM324MTX/NOPB provides the largest inventory among enhanced-performance alternatives with 21,068 units. All recommended substitutes maintain active production status with continuous supply availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All recommended substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), ensuring compatibility with modern manufacturing processes and environmental regulations.

Q: Which substitute part is recommended for new design implementations?

A: For new designs requiring the original LP2902PWRE4 specifications, use LP2902PWR. For applications benefiting from enhanced performance, use LM2902MTX/NOPB (Tape & Reel format with 2,900 units in stock) or LM324MTX/NOPB (highest inventory availability). For temperature-restricted applications (0°C to 70°C), LP324MTX/NOPB provides cost-optimized performance.
