LM2902PWRE4 Equivalent & Substitute Parts

Part Overview

The LM2902PWRE4 is a general-purpose operational amplifier manufactured by Texas Instruments, configured as a 4-circuit integrated circuit in 14-TSSOP surface mount packaging. This device is classified as Last Time Buy, indicating discontinued production with limited remaining inventory (5008 pcs). The LM2902PWRE4 operates across a wide supply voltage range (3V to 26V) and temperature range (-40°C to 125°C), making it suitable for analog signal processing applications requiring low input bias current and moderate bandwidth characteristics.

Due to Last Time Buy status, identifying functionally equivalent substitute parts is essential for design continuity and long-term component availability. Substitute parts must maintain electrical compatibility across critical parameters including supply voltage range, input bias current, output current capability, and thermal operating range.

Frequently Asked Questions (FAQ)

Q1: Can LM2902MTX/NOPB replace LM2902PWRE4 in all applications?

A: LM2902MTX/NOPB is electrically compatible for most applications but has a reduced upper operating temperature limit of 85°C versus the original 125°C. Applications requiring operation above 85°C require alternative substitutes such as BA2902FV-E2 or BA2902SFV-E2.

Q2: What is the difference between 14-TSSOP and 14-LSSOP packaging?

A: Both 14-TSSOP and 14-LSSOP are surface mount packages with identical pitch (0.173" width, 4.40mm) and pin count. The primary difference is in body profile and thermal characteristics. Both are mechanically and electrically compatible for PCB layout purposes. Verify thermal performance requirements for your specific application.

Q3: Why do some substitute parts have lower gain bandwidth product (500 kHz vs. 1.2 MHz)?

A: The Rohm BA series (BA10324AFV-E2, BA2902FV-E2, BA2902SFV-E2) are optimized for lower power consumption and extended temperature operation. The reduced bandwidth is a design trade-off. Select these parts only if your application bandwidth requirement is ≤500 kHz.

Q4: Is LM2902DTBR2G suitable as a direct replacement?

A: LM2902DTBR2G offers active product status and extended temperature range but has significantly higher input bias current (90 nA vs. 20 nA). This is acceptable only for applications where input bias current specification is not critical. Verify circuit performance before implementation.

Q5: Can LM324 series parts replace LM2902 series?

A: LM324MT/NOPB and LM324MTX/NOPB share identical electrical specifications with LM2902 variants but operate only from 0°C to 70°C. These are not suitable for applications requiring -40°C lower temperature operation.

Q6: What inventory considerations apply to substitute selection?

A: LM324MTX/NOPB offers the highest inventory (21068 pcs), followed by BA10324AFV-E2 (27661 pcs). LM2902MTX/NOPB has moderate inventory (2900 pcs). For long-term supply assurance, prioritize parts with active product status and higher inventory levels.

Q7: Are all substitute parts RoHS3 compliant?

A: Yes. All recommended substitute parts carry ROHS3 Compliant status and MSL Level 1 (Unlimited moisture sensitivity), matching the original LM2902PWRE4 compliance profile.

Q8: Which substitute is best for cost-sensitive applications?

A: BA2902FV-E2 and BA2902SFV-E2 offer lower supply current (0.7 mA vs. 1.4 mA) and reduced slew rate, resulting in lower power consumption. These are suitable for battery-powered or power-constrained applications with bandwidth requirements ≤500 kHz.
