LM358PW Equivalent & Substitute Parts Reference

Part Overview

The LM358PW is a general-purpose operational amplifier manufactured by Texas Instruments, featuring dual circuits in an 8-TSSOP surface-mount package. This device is classified as Last Time Buy, indicating discontinued production with limited inventory availability. The LM358PW operates across a 3V to 30V supply range with a 700 kHz gain bandwidth product and 0.3V/µs slew rate, making it suitable for general-purpose analog signal processing applications.

Substitute parts are necessary due to the Last Time Buy status of the LM358PW. Alternative devices with equivalent or enhanced electrical characteristics and compatible packaging are available from multiple manufacturers to ensure design continuity and long-term supply chain reliability.

Engineering Selection Recommendations

Primary Substitutes (Electrical Equivalents with Active Status):

LM2904ATH-13 and LM2904M8-13 from Diodes Incorporated are the recommended primary substitutes. Both devices maintain identical electrical specifications to the LM358PW (0.3V/µs slew rate, 700 kHz gain bandwidth product, 20 nA input bias current) while offering extended operating temperature range (-40°C to 125°C) and higher maximum supply voltage (36V). Both are in Active product status with substantial inventory availability. LM2904ATH-13 is packaged in 8-TSSOP, providing direct footprint compatibility. LM2904M8-13 uses 8-MSOP packaging, which requires PCB layout verification for pin-to-pin compatibility.

Secondary Substitutes (Enhanced Performance):

LM258APT and LM258PT from STMicroelectronics offer enhanced performance with 0.6V/µs slew rate and 1.1 MHz gain bandwidth product. Both are AEC-Q100 qualified automotive-grade devices in Active status. These parts are suitable for applications requiring faster signal processing while maintaining the same supply voltage range and output current specifications. LM258APT exhibits superior input offset voltage (1 mV) compared to LM258PT (5 mV).

Alternative Substitutes (Extended Temperature Range):

LM2904PT from Rohm Semiconductor provides extended operating temperature range (-40°C to 125°C) with marginally enhanced gain bandwidth product (800 kHz) and maintains 0.3V/µs slew rate. This device is suitable for industrial and automotive applications requiring wider temperature operation.

Not Recommended for New Designs:

LM358PWR from Rohm Semiconductor carries "Not For New Designs" status and should be avoided for new product development despite electrical equivalence.

High-Performance Alternative (Not Recommended for Direct Substitution):

BA4580RFVT-E2 exhibits significantly different electrical characteristics (4V/µs slew rate, 5 MHz gain bandwidth product, 100 nA input bias current, 6 mA supply current). This device is suitable only for applications requiring substantially higher performance and is not a direct substitute due to different operating characteristics and higher power consumption.

Frequently Asked Questions (FAQ)

Q1: Can LM2904ATH-13 directly replace LM358PW on existing PCBs?

A: Yes. LM2904ATH-13 is packaged in 8-TSSOP with identical pin configuration and footprint dimensions (0.173", 4.40mm width) as the LM358PW. Electrical specifications are equivalent. No PCB modifications are required.

Q2: What is the difference between LM2904ATH-13 and LM2904M8-13?

A: Both devices have identical electrical specifications. The primary difference is packaging: LM2904ATH-13 uses 8-TSSOP (0.173" width), while LM2904M8-13 uses 8-MSOP (0.118" width). The MSOP package is physically smaller and requires verification of PCB pad layout compatibility before substitution.

Q3: Why is LM258APT listed as a substitute if it has different electrical characteristics?

A: LM258APT is classified as an enhanced-performance alternative. It maintains core compatibility (dual circuits, 20 nA input bias, 40 mA output current, 3V to 30V supply range, 8-TSSOP package) while offering faster slew rate (0.6V/µs vs. 0.3V/µs) and higher gain bandwidth product (1.1 MHz vs. 700 kHz). It is suitable for applications where improved performance is beneficial or required.

Q4: Is LM358PWR a viable substitute?

A: LM358PWR is electrically equivalent to LM358PW but carries "Not For New Designs" status from Rohm Semiconductor. While technically compatible, it should not be selected for new product development. Active alternatives such as LM2904ATH-13 are preferred.

Q5: Can BA4580RFVT-E2 replace LM358PW?

A: BA4580RFVT-E2 is not a direct substitute. While both are packaged in 8-TSSOP, the BA4580RFVT-E2 exhibits substantially different electrical characteristics: 4V/µs slew rate (vs. 0.3V/µs), 5 MHz gain bandwidth product (vs. 700 kHz), 100 nA input bias current (vs. 20 nA), and 6 mA supply current (vs. 500 µA). This device is suitable only for high-performance applications requiring these enhanced specifications.

Q6: What is the significance of AEC-Q100 qualification on LM258APT and LM258PT?

A: AEC-Q100 qualification indicates these devices meet automotive industry reliability and quality standards. This certification is relevant only if the application requires automotive-grade components. For general-purpose applications, AEC-Q100 qualification provides additional assurance of component reliability but is not a functional requirement.

Q7: How does supply voltage range affect substitution?

A: The LM358PW operates from 3V to 30V. Substitutes with extended maximum supply voltage (such as LM2904ATH-13 at 36V) are fully compatible and provide additional design margin. Substitutes with lower maximum supply voltage are not acceptable. Minimum supply voltage must not exceed 3V for compatibility.

Q8: Are there package compatibility considerations between 8-TSSOP and 8-MSOP?

A: Yes. While both packages have 8 pins, the 8-MSOP package (0.118" width) is physically smaller than 8-TSSOP (0.173" width). Pin spacing and pad layout differ. Direct PCB substitution is not possible without layout verification. Consult device datasheets and PCB design files before selecting MSOP alternatives.

Q9: What inventory status should influence substitution decisions?

A: Active status indicates ongoing production and long-term availability. Last Time Buy status indicates discontinued production with limited remaining inventory. Not For New Designs status indicates the manufacturer recommends against new product integration. For new designs, select only Active status devices. For legacy product support, Last Time Buy devices may be acceptable if inventory is confirmed available.

Q10: How do input offset voltage differences affect circuit performance?

A: Input offset voltage determines DC accuracy in precision applications. The LM358PW specifies 3 mV maximum. Substitutes with lower offset voltage (1 mV for LM2904ATH-13, LM258APT) provide improved DC accuracy. Substitutes with higher offset voltage (5 mV for LM258PT) may require additional circuit compensation in precision applications. For general-purpose applications, these differences are typically negligible.
