Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LM358ADGK are selected based on functional equivalence across critical electrical and mechanical parameters. The primary substitution criteria include: dual-circuit general-purpose amplifier topology, push-pull output configuration, compatible supply voltage range (3V to 30V minimum), surface mount packaging with 8-pin TSSOP or MSOP footprint compatibility, and ROHS3 compliance.

The LM358ADGK operates with a slew rate of 0.3V/µs and gain bandwidth product of 700 kHz. Substitute parts must maintain compatibility within the specified operating temperature range and support the required output current per channel (30 mA). Input bias current and input offset voltage specifications define the precision characteristics of the amplifier; substitutes with equivalent or superior performance in these parameters ensure functional compatibility. All substitute parts identified maintain the same package footprint class and surface mount technology, enabling direct board-level replacement without layout modifications.

Parameter Comparison

Engineering Selection Recommendations

The LM358ADGK is classified as obsolete, necessitating transition to active production alternatives. Both substitute parts—LM358AWST and LM358FVT-GE2—are currently in active production status and maintain ROHS3 compliance.

LM358AWST (STMicroelectronics): This substitute is qualified to AEC-Q100 automotive standards and carries unlimited moisture sensitivity level (MSL 1), indicating superior reliability for extended storage and field deployment. The LM358AWST demonstrates enhanced electrical performance with a slew rate of 0.6V/µs (double the original specification) and gain bandwidth product of 1.1 MHz, along with improved input offset voltage of 1 mV. Output current capability is increased to 40 mA per channel. This part is suitable for applications requiring automotive-grade qualification or extended operational reliability.

LM358FVT-GE2 (Rohm Semiconductor): This substitute maintains electrical characteristics closely aligned with the LM358ADGK, with identical slew rate (0.3V/µs) and output current per channel (30 mA). The gain bandwidth product is marginally higher at 800 kHz. Operating temperature range extends to -40°C to 85°C, providing broader environmental coverage. Supply voltage maximum extends to 32V. This part carries unlimited MSL rating and REACH unaffected status. The LM358FVT-GE2 is optimal for applications requiring minimal electrical parameter deviation from the original design.

Both substitutes support the same 8-pin surface mount package footprint, enabling direct replacement without PCB redesign. Selection between substitutes depends on specific application requirements: automotive qualification and enhanced performance favor LM358AWST, while minimal parameter deviation and extended temperature range favor LM358FVT-GE2.

Frequently Asked Questions (FAQ)

Q: Can the LM358AWST directly replace the LM358ADGK on existing PCBs?

A: Yes. Both devices use compatible 8-TSSOP and 8-MSOP surface mount packages with identical 0.118" (3.00mm) width specifications. Pin configuration and electrical interface are functionally equivalent, enabling direct board-level substitution without layout modifications.

Q: What are the key electrical differences between the LM358ADGK and its substitutes?

A: The LM358AWST offers enhanced slew rate (0.6V/µs versus 0.3V/µs) and higher gain bandwidth product (1.1 MHz versus 700 kHz), with improved input offset voltage (1 mV versus 2 mV). The LM358FVT-GE2 maintains the original slew rate and output current specifications while providing marginally higher gain bandwidth product (800 kHz). Both substitutes feature lower input bias current (20 nA versus 15 nA) and improved input offset voltage.

Q: Are there temperature range considerations for substitution?

A: The LM358ADGK operates from 0°C to 70°C. The LM358AWST maintains this range. The LM358FVT-GE2 extends operation to -40°C to 85°C, providing broader environmental coverage for applications requiring extended temperature performance. Applications limited to the original 0°C to 70°C range are compatible with all three parts.

Q: What compliance certifications apply to the substitute parts?

A: Both LM358AWST and LM358FVT-GE2 are ROHS3 compliant. The LM358AWST carries AEC-Q100 automotive qualification. The LM358FVT-GE2 carries REACH unaffected status. All three parts are classified under ECCN EAR99 and HTSUS 8542.33.0001.

Q: How do supply current specifications affect circuit design?

A: The LM358ADGK draws 500µA supply current. The LM358AWST draws 700µA, and the LM358FVT-GE2 draws 600µA. For battery-powered or low-power applications, the original LM358ADGK specification should be verified against substitute power budgets. The increased supply current in substitutes reflects enhanced performance characteristics and does not indicate functional incompatibility.

Q: What is the significance of moisture sensitivity level (MSL) ratings?

A: The LM358ADGK carries MSL 2 (1 Year), indicating standard moisture sensitivity. Both substitutes carry MSL 1 (Unlimited), indicating superior moisture resistance and extended shelf life without special storage requirements. This represents an improvement in component reliability and handling flexibility.

Q: Can the LM358AWST be used in applications originally designed for the LM358ADGK without circuit modifications?

A: Yes. The LM358AWST maintains compatible supply voltage range (3V to 30V), output current per channel (40 mA, exceeding the 30 mA requirement), and package footprint. Enhanced electrical performance (higher slew rate and bandwidth) does not create incompatibility. Applications benefit from improved performance characteristics without requiring design changes.

Q: Is the LM358FVT-GE2 suitable for high-temperature applications?

A: The LM358FVT-GE2 operates to 85°C maximum, compared to 70°C for the LM358ADGK. This extended range accommodates applications in elevated ambient temperature environments. The LM358AWST maintains the original 70°C maximum operating temperature.
