Substitute Part Grouping Explanation
Substitution of the LM358DG is determined by the following critical parameters: amplifier type (general purpose), number of circuits (2), package type (8-SOIC), mounting method (surface mount), and electrical specifications including gain bandwidth product, supply voltage range, input bias current, and output current capability. Parts are grouped into three categories based on substitution compatibility:
Direct Substitutes maintain identical or superior electrical performance within the same package footprint and are pin-compatible replacements. These parts satisfy the core functional requirements of the LM358DG while offering improved product status or compliance certifications.
Upgrade Substitutes provide enhanced operating temperature ranges or automotive-grade qualifications (AEC-Q100) while maintaining the same package and pin configuration. These parts are suitable for applications requiring extended temperature performance or automotive compliance.
Similar Alternatives offer comparable functionality but with different amplifier technology (J-FET input stage) or modified electrical characteristics. These parts are considered when the application permits trade-offs in input bias current, slew rate, or supply voltage requirements.

Engineering Selection Recommendations
For Direct Replacement (Pin-Compatible, Same Performance Class):
LM358MX/NOPB (Texas Instruments) is the primary direct substitute. This part maintains identical electrical specifications to the LM358DG, including 1 MHz gain bandwidth product, 45 nA input bias current, and 32V maximum supply voltage. The LM358MX/NOPB carries Active product status with ROHS3 compliance and offers the highest inventory availability (74,281 units), ensuring supply continuity.
LM358D (STMicroelectronics) provides an alternative direct substitute with Active product status and AEC-Q100 automotive qualification. While the gain bandwidth product is reduced to 700 kHz and maximum supply voltage is limited to 30V, the input bias current is improved to 20 nA. This part is suitable for applications where automotive compliance is required.
LM358S-13 (Diodes Incorporated) offers Active product status with 20,400 units in stock. This part maintains the 32V maximum supply voltage and 1 MHz equivalent performance characteristics, though it specifies differential output type.
For Extended Temperature Range Applications:
LM2904VQDRG4Q1 (Texas Instruments) is recommended for applications requiring automotive-grade components with AEC-Q100 qualification and extended operating temperature range (-40°C to 125°C). This part maintains the 8-SOIC package and provides 700 kHz gain bandwidth product with reduced supply current (500µA per channel). Active product status ensures long-term availability.
LM2904VQDRG4 (Texas Instruments) provides similar extended temperature capability (-40°C to 125°C) without automotive qualification. This part is suitable for industrial applications requiring wider temperature performance than the standard 0°C to 70°C range.
For Applications Permitting Alternative Amplifier Technology:
ADA4062-2ARZ series (Analog Devices Inc.) represents a technology upgrade utilizing J-FET input stage architecture. These parts offer superior input bias current (2 pA versus 45 nA), lower input offset voltage (750 µV versus 2 mV), and higher slew rate (3.3V/µs). However, the minimum supply voltage requirement is 8V (versus 3V for LM358DG), and output current is reduced to 20 mA per channel. These parts are suitable for precision instrumentation and low-noise applications where the supply voltage constraint is acceptable.
Compliance and Certification Considerations:
All recommended substitutes maintain ROHS3 compliance and REACH unaffected status, consistent with the original LM358DG. Parts designated with AEC-Q100 qualification (LM358D, LM2904VQDRG4Q1) are suitable for automotive applications. Moisture sensitivity level remains at MSL 1 (Unlimited) across all substitutes, eliminating moisture-related handling constraints.
Frequently Asked Questions (FAQ)
Q: Can LM358MX/NOPB be used as a direct replacement for LM358DG without circuit modification?
A: Yes. LM358MX/NOPB is pin-compatible and maintains identical electrical specifications including gain bandwidth product (1 MHz), supply voltage range (3V to 32V), input bias current (45 nA), and output current (40 mA per channel). The 8-SOIC package footprint is identical. No circuit modifications are required.
Q: What is the primary difference between LM358D and LM358MX/NOPB?
A: LM358D (STMicroelectronics) reduces gain bandwidth product to 700 kHz and maximum supply voltage to 30V, while improving input bias current to 20 nA. LM358D includes AEC-Q100 automotive qualification. LM358MX/NOPB maintains the original 1 MHz bandwidth and 32V supply rating. Selection depends on whether automotive compliance or reduced bandwidth is acceptable for the application.
Q: Are the LM2904 series parts direct substitutes for LM358DG?
A: LM2904 series parts are not direct substitutes. While they share the same 8-SOIC package and dual-circuit configuration, they feature reduced gain bandwidth product (700 kHz versus 1 MHz) and different supply current characteristics. LM2904 parts are suitable only when the application permits reduced bandwidth performance. Extended temperature variants (LM2904VQDRG4Q1) are appropriate for automotive or industrial applications requiring -40°C to 125°C operation.
Q: What are the key limitations of ADA4062-2ARZ compared to LM358DG?
A: ADA4062-2ARZ requires minimum 8V supply voltage (versus 3V for LM358DG), limiting use in low-voltage applications. Output current is reduced to 20 mA per channel (versus 40 mA). However, ADA4062-2ARZ offers superior input bias current (2 pA), lower input offset voltage (750 µV), and higher slew rate (3.3V/µs), making it suitable for precision instrumentation applications where supply voltage constraints are acceptable.
Q: Is the 8-SOIC package identical across all substitute parts?
A: Yes. All substitute parts specified in this reference use the 8-SOIC package with 0.154" (3.90mm) width. Package footprint and pin configuration are identical, permitting direct PCB layout compatibility. Packaging format (Tube, Tape & Reel, Cut Tape) varies by supplier but does not affect electrical or mechanical compatibility.
Q: Which substitute offers the best long-term availability?
A: LM358MX/NOPB (Texas Instruments) offers the highest inventory availability at 74,281 units with Active product status, ensuring sustained supply. LM358S-13 (Diodes Incorporated) provides secondary availability with 20,400 units. Both parts maintain Active status and ROHS3 compliance, supporting long-term design continuity.
Q: Can LM358DRG3 be used as a substitute despite Last Time Buy status?
A: LM358DRG3 is available with 1,370 units in stock but carries Last Time Buy status, indicating discontinued production. While electrically compatible (700 kHz bandwidth, 30V maximum supply), this part is not recommended for new designs due to limited availability and eventual supply exhaustion. LM358MX/NOPB or LM358S-13 are preferred alternatives with Active status.
Q: What is the significance of ROHS3 compliance across all substitutes?
A: ROHS3 compliance indicates conformance to Restriction of Hazardous Substances Directive 3, restricting lead and other hazardous materials. All substitute parts maintain ROHS3 status, ensuring environmental compliance and regulatory alignment with the original LM358DG. This eliminates compliance-related design constraints when transitioning to substitute components.
