LM358AM Equivalent & Substitute Parts
Part Overview
The LM358AM is a general-purpose operational amplifier manufactured by onsemi, configured as a dual-channel integrated circuit in 8-SOIC surface mount packaging. This device is classified as obsolete, though 1460 pieces remain in current inventory. The LM358AM operates across a supply voltage range of 3V to 32V with an operating temperature range of 0°C to 70°C, making it suitable for standard industrial and consumer applications requiring dual op-amp functionality.
Due to the obsolete product status of the LM358AM, identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term production requirements. Active alternatives with compatible electrical and mechanical specifications are available from multiple manufacturers.

Engineering Selection Recommendations
Primary Substitutes (Identical Operating Temperature Range):
The LM358DR2G (onsemi) and LM358AM/NOPB (Texas Instruments) are direct substitutes for the LM358AM. Both maintain the 0°C to 70°C operating temperature specification, identical supply voltage range (3V to 32V), and equivalent input/output electrical characteristics. The LM358DR2G offers improved output current capability (40 mA vs. 30 mA per channel) and reduced supply current (800 µA vs. 1.5 mA), while maintaining full compatibility. Both parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating.
Extended Temperature Range Alternatives:
The LM2904VDR2G (onsemi) and NCV2904DR2G (onsemi) provide extended operating temperature ranges (-40°C to 125°C) while maintaining the same 8-SOIC package and 3V to 32V supply voltage specification. These parts are suitable for applications requiring operation beyond the standard 0°C to 70°C range. The LM2904VDR2G exhibits higher input offset voltage (7 mV vs. 2 mV) but delivers equivalent output current capability (40 mA per channel).
Higher Performance Alternative:
The MC34072DR2G (onsemi) offers enhanced performance characteristics including higher gain bandwidth product (4.5 MHz vs. 1 MHz), improved input offset voltage (1 mV), and extended supply voltage range (3V to 44V). This part is suitable for applications requiring superior frequency response and precision, though it operates within the same 0°C to 70°C temperature range as the LM358AM.
Automotive-Grade Option:
The LM358AD (STMicroelectronics) is qualified to AEC-Q100 automotive standards and provides superior input bias current (20 nA vs. 45 nA) and improved input offset voltage (1 mV). This part is recommended for automotive and mission-critical applications requiring enhanced reliability certification.
All recommended substitutes maintain REACH Unaffected status, EAR99 ECCN classification, and MSL 1 moisture sensitivity rating, ensuring regulatory compliance and handling consistency with the original LM358AM specification.
Frequently Asked Questions (FAQ)
Q: Can the LM358DR2G directly replace the LM358AM in existing designs?
A: Yes. The LM358DR2G maintains identical electrical specifications for input bias current (45 nA), input offset voltage (2 mV), and supply voltage range (3V to 32V). Both parts use the 8-SOIC package. The LM358DR2G is an active product with improved output current capability (40 mA vs. 30 mA per channel) and lower supply current consumption (800 µA vs. 1.5 mA), making it a direct functional replacement.
Q: What is the difference between LM2904VDR2G and LM358DR2G?
A: Both parts share identical package, supply voltage range, and input bias current specifications. The primary differences are: (1) LM2904VDR2G operates across -40°C to 125°C versus LM358DR2G at 0°C to 70°C; (2) LM2904VDR2G has higher input offset voltage (7 mV vs. 2 mV); (3) LM2904VDR2G maintains 1.5 mA supply current versus LM358DR2G at 800 µA. Selection depends on required operating temperature range and power consumption constraints.
Q: Is the MC34072DR2G suitable as a substitute for the LM358AM?
A: The MC34072DR2G is mechanically and electrically compatible in terms of package (8-SOIC) and supply voltage range (3V to 32V). However, it represents a higher-performance alternative with 4.5 MHz gain bandwidth product versus 1 MHz for the LM358AM, and superior input offset voltage (1 mV). It is suitable for applications requiring enhanced frequency response and precision, though it operates within the same 0°C to 70°C temperature range.
Q: Why does the LM358AD have lower input bias current than the LM358AM?
A: The LM358AD is manufactured by STMicroelectronics and is qualified to AEC-Q100 automotive standards. The improved input bias current specification (20 nA vs. 45 nA) reflects enhanced device design and manufacturing process control required for automotive applications. This part is recommended for designs requiring automotive-grade reliability and certification.
Q: Can I use LM2904DR2G if my application requires operation above 26V?
A: No. The LM2904DR2G has a maximum supply voltage specification of 26V, which is below the LM358AM specification of 32V. For applications requiring operation up to 32V, use LM358DR2G, LM2904VDR2G, or LM358AM/NOPB instead.
Q: Are all substitute parts ROHS3 compliant?
A: All active substitute parts listed (LM258DR2G, LM2904DR2G, LM2904VDR2G, LM358DR2G, MC34072DR2G, NCV2904DR2G, LM358AD, and LM358AM/NOPB) are ROHS3 compliant. The original LM358AM does not specify RoHS status due to its obsolete classification.
Q: What is the significance of MSL 1 (Unlimited) moisture sensitivity rating?
A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture control during storage or handling. All listed parts maintain this rating, ensuring consistent handling procedures and eliminating the need for baking or desiccant storage protocols.
Q: Which substitute offers the lowest power consumption?
A: The LM358AD (STMicroelectronics) offers the lowest supply current at 700 µA (per dual channels), followed by LM258DR2G and LM358DR2G at 800 µA. These parts are suitable for battery-powered or low-power applications where supply current minimization is critical.
Q: Can I substitute the LM358AM with NCV2904DR2G for extended temperature operation?
A: Yes. The NCV2904DR2G operates across -40°C to 125°C, providing extended temperature coverage beyond the LM358AM specification of 0°C to 70°C. Both parts maintain identical 8-SOIC packaging, 3V to 32V supply voltage range, and 45 nA input bias current. The NCV2904DR2G has higher input offset voltage (7 mV vs. 2 mV) but delivers equivalent output current capability (40 mA per channel).
