LM358WPT Equivalent & Substitute Parts
Part Overview
The LM358WPT is a general-purpose operational amplifier featuring two independent circuits in an 8-TSSOP surface mount package, manufactured by Rohm Semiconductor. This device operates across a wide supply voltage range of 3V to 32V and is suitable for applications requiring dual-channel amplification with moderate bandwidth requirements.
The LM358WPT carries a product status of "Not For New Designs," indicating that while the device remains available in inventory (2300 pcs), it is no longer recommended for new circuit development. This status necessitates identification of equivalent and substitute parts that maintain functional compatibility while offering active product status or enhanced performance characteristics.

Substitute Part Grouping Explanation
Substitution of the LM358WPT is determined by compatibility across the following critical parameters:
Package and Pinout Compatibility: All substitute parts must utilize the 8-TSSOP surface mount package with identical 0.173" (4.40mm) width to ensure direct PCB footprint compatibility.
Dual-Circuit Configuration: All substitutes maintain the two independent operational amplifier circuits required for dual-channel applications.
Supply Voltage Range: Substitute parts must support the minimum 3V supply requirement. The LM358WPT maximum of 32V establishes an upper boundary; substitutes with lower maximum ratings (30V) remain compatible for applications not exceeding 30V operation.
Input Bias Current: The 20 nA specification is maintained across all general-purpose substitute options, ensuring equivalent input impedance characteristics.
Voltage Input Offset: Substitutes with input offset specifications of 1mV to 5mV remain functionally compatible, as these variations fall within typical application tolerances.
Output Current Capability: The 30mA per-channel specification of the LM358WPT is met or exceeded by substitute parts rated at 40mA or 60mA per channel.
Slew Rate and Bandwidth: The LM358WPT operates at 0.3V/µs slew rate and 800kHz gain-bandwidth product. Substitute parts with equal or superior performance (higher slew rate, higher bandwidth) provide enhanced frequency response while maintaining backward compatibility.
Temperature Range: Operating temperature ranges of -40°C to 85°C (LM358WPT) through -40°C to 125°C (extended range substitutes) are compatible for applications within the LM358WPT's specified range.

Engineering Selection Recommendations
Direct Functional Replacement (Identical Electrical Performance):
The LM2904PT (Rohm Semiconductor, Active status) provides direct functional equivalence to the LM358WPT. Both devices share identical electrical specifications: 0.3V/µs slew rate, 800kHz gain-bandwidth product, 1mV input offset voltage, and 30mA output current per channel. The LM2904PT extends the operating temperature range to -40°C to 125°C and maintains active product status, making it the primary recommendation for new designs requiring the LM358WPT's performance profile.
Enhanced Performance Substitutes (Higher Bandwidth and Slew Rate):
The LM258 series (LM258PT, LM258WPT, LM258WYPT, LM258YPT, LM258APT) from STMicroelectronics offers improved performance with 0.6V/µs slew rate and 1.1MHz gain-bandwidth product while maintaining the same 20nA input bias current and 8-TSSOP package. These devices carry active product status and AEC-Q100 automotive qualification. The LM258WPT and LM258WYPT variants provide the lowest input offset voltage (2mV) and highest output current (60mA per channel). Selection among LM258 variants depends on specific input offset voltage and output current requirements.
Low-Power Alternative:
The LM2904AVQPWR (Texas Instruments, Active status) reduces supply current to 500µA (compared to 600µA in the LM358WPT) while maintaining identical input bias current, input offset voltage, and output current specifications. This device supports extended temperature operation (-40°C to 125°C) and is suitable for power-constrained applications.
High-Performance JFET Input Alternative:
The TL062IPWR (Texas Instruments, Active status) employs J-FET input architecture, delivering significantly lower input bias current (30pA versus 20nA) and higher slew rate (3.5V/µs). However, this device requires a minimum 10V supply voltage and delivers only 20mA output current per channel, making it suitable only for applications where these specifications align with system requirements.
Package Consideration:
The LM358DMR2G (onsemi, Active status) utilizes an 8-MSOP package (0.118" width) rather than the standard 8-TSSOP (0.173" width). This package variant is not directly interchangeable on existing PCBs designed for 8-TSSOP footprints and should be selected only when PCB redesign is feasible.
Discontinued Status:
The LM2904AVQPWRG4 (Texas Instruments) is marked as discontinued at DiGi Electronics and should not be selected for new designs despite meeting electrical specifications.
Frequently Asked Questions (FAQ)
Q: Can I directly replace the LM358WPT with any of the listed substitute parts?
A: Direct replacement on existing PCBs is possible only with parts using the identical 8-TSSOP package (0.173" width). The LM358DMR2G uses an 8-MSOP package and is not pin-compatible. All other listed substitutes use the standard 8-TSSOP package and are physically interchangeable. Electrical compatibility must be verified against specific application requirements.
Q: What is the primary reason to replace the LM358WPT?
A: The LM358WPT carries a "Not For New Designs" product status. For new circuit development, the LM2904PT provides identical electrical performance with active product status. For applications requiring enhanced bandwidth and slew rate, the LM258 series offers superior performance while maintaining backward compatibility.
Q: Does the LM258 series provide better performance than the LM358WPT?
A: Yes. The LM258 series (LM258PT, LM258WPT, LM258WYPT, LM258YPT, LM258APT) delivers 0.6V/µs slew rate and 1.1MHz gain-bandwidth product compared to the LM358WPT's 0.3V/µs and 800kHz. These improvements enable faster signal processing and higher-frequency operation. Input bias current remains identical at 20nA, ensuring equivalent input impedance.
Q: Are there supply voltage compatibility concerns with substitute parts?
A: The LM358WPT supports 3V to 32V operation. Most substitutes support 3V to 30V, which is compatible for applications not exceeding 30V. The TL062IPWR requires a minimum 10V supply and is not suitable for 3V to 10V applications. Verify the specific supply voltage range of your application before selection.
Q: What is the difference between LM258WPT and LM258WYPT?
A: Both devices share identical electrical specifications: 0.6V/µs slew rate, 1.1MHz gain-bandwidth product, 2mV input offset voltage, and 60mA output current per channel. The suffix variation indicates different manufacturing or qualification batches. Both are active products with AEC-Q100 automotive qualification and are functionally equivalent.
Q: Why does the TL062IPWR have such low input bias current?
A: The TL062IPWR employs J-FET input architecture, which inherently produces lower input bias current (30pA) compared to bipolar input designs (20nA in the LM358WPT). This characteristic makes the TL062IPWR suitable for high-impedance signal sources. However, the J-FET design requires higher minimum supply voltage (10V) and provides lower output current (20mA per channel).
Q: Can I use the LM358DMR2G as a direct replacement?
A: The LM358DMR2G is not a direct PCB replacement due to its 8-MSOP package (0.118" width) versus the LM358WPT's 8-TSSOP package (0.173" width). These packages have different pinout footprints. The LM358DMR2G is suitable only if PCB redesign is performed. Additionally, this device operates only from 0°C to 70°C, which is a narrower temperature range than the LM358WPT.
Q: What does AEC-Q100 qualification mean?
A: AEC-Q100 is an automotive electronics qualification standard. Devices carrying this qualification (LM258 series variants) have undergone rigorous testing for automotive applications, including temperature cycling, vibration, and reliability assessments. This qualification is relevant only if your application requires automotive-grade components.
Q: Is the LM2904AVQPWRG4 available for new designs?
A: No. The LM2904AVQPWRG4 is marked as discontinued at DiGi Electronics. For new designs requiring the LM2904 electrical characteristics, select the LM2904AVQPWR (active status) instead.
Q: How do I choose between LM258PT and LM258WPT?
A: Both devices share identical electrical performance. The primary difference is packaging: LM258PT uses Cut Tape (CT) & Digi-Reel® packaging, while LM258WPT uses Tape & Reel (TR) packaging. Selection depends on your procurement and assembly process requirements. LM258WPT offers higher output current per channel (60mA versus 40mA for LM258PT).
