LM358SNG Equivalent & Substitute Parts

Part Overview

The LM358SNG is a general-purpose operational amplifier featuring two independent circuits in an 8-DIP through-hole package, manufactured by onsemi. This device is classified as obsolete, though it remains functionally equivalent to several active alternatives currently available in the market. The LM358SNG operates across a wide supply voltage range of 3V to 32V and is suitable for applications requiring low-power, general-purpose amplification with moderate bandwidth characteristics.

Due to its obsolete status, identifying equivalent substitute parts is essential for design continuity, procurement reliability, and long-term product support. Active alternatives maintain the same functional specifications while offering improved availability and compliance certifications.

Substitute Part Grouping Explanation

Substitution of the LM358SNG is determined by strict alignment of electrical and mechanical parameters. The following criteria establish valid equivalency:

Primary Substitution Criteria:

Amplifier Type: General Purpose (matching functional classification)
Number of Circuits: 2 (dual-channel configuration)
Voltage Supply Range: Minimum 3V, Maximum ≥32V (full compatibility with LM358SNG range)
Current - Input Bias: ≤45 nA (equal or lower bias current acceptable)
Voltage - Input Offset: ≤2 mV (equal or lower offset voltage acceptable)
Current - Output / Channel: ≥40 mA (equal or higher output current acceptable)
Mounting Type: Through Hole (mechanical compatibility)
Package / Case: 8-DIP (0.300", 7.62mm) (pin-for-pin compatibility)

Secondary Considerations:

Product Status: Active status preferred for long-term availability
RoHS Compliance: ROHS3 Compliant status indicates modern manufacturing standards
Operating Temperature Range: Extended ranges (-40°C to 85°C) provide broader application flexibility

Substitute parts are grouped into two categories: Direct Pin-Compatible Replacements (identical 8-DIP package) and Functional Equivalents with Enhanced Specifications (same electrical performance with improved parameters).

Engineering Selection Recommendations

Direct Pin-Compatible Replacements (8-DIP Through-Hole Package):

The following parts provide direct mechanical and electrical compatibility with the LM358SNG and are recommended as primary substitutes:

LM358AN/NOPB (Texas Instruments) — Active status, identical electrical specifications, ROHS3 compliant. Highest compatibility for drop-in replacement applications.
LM358N/NOPB (Texas Instruments) — Active status, identical electrical specifications, ROHS3 compliant. Functionally equivalent to LM358AN/NOPB.
LM358P (Texas Instruments) — Active status, improved input bias current (20 nA vs. 45 nA), ROHS3 compliant. Suitable where lower bias current is beneficial. Maximum supply voltage is 30V (vs. 32V for LM358SNG).
AS358P-E1 (Diodes Incorporated) — Active status, improved input bias current (20 nA), extended temperature range (-40°C to 85°C), maximum supply voltage 36V. ROHS3 compliant.
LM258P (Texas Instruments) — Active status, improved input bias current (20 nA), extended temperature range (-25°C to 85°C). ROHS3 compliant. Suitable for applications requiring broader temperature operation.

Enhanced Performance Alternatives (8-DIP Through-Hole Package):

CA3240AEZ (Renesas Electronics) — Active status, significantly lower input bias current (10 pA), extended temperature range (-40°C to 85°C), maximum supply voltage 36V. ROHS3 compliant. Higher supply current (8 mA) requires consideration in power-sensitive applications.
BA15218 (Rohm Semiconductor) — Active status, superior input offset voltage (0.5 µV vs. 2 mV), higher output current (50 mA), extended temperature range (-40°C to 85°C). ROHS3 compliant. Minimum supply voltage is 4V (vs. 3V for LM358SNG).

Alternative Amplifier Type (8-DIP Through-Hole Package):

LF353N/NOPB and LF353P (Texas Instruments) — Active status, J-FET input type with extremely low input bias current (50 pA), higher slew rate (13 V/µs), extended temperature range (0°C to 70°C). ROHS3 compliant. Minimum supply voltage is 10V and 7V respectively, limiting compatibility with 3V supply applications.

Surface-Mount Alternative:

LM358DR2G (onsemi) — Active status, identical electrical specifications to LM358SNG, 8-SOIC surface-mount package. Suitable for PCB redesigns requiring surface-mount technology. ROHS3 compliant.

Selection Basis:

Obsolete Status Mitigation: All recommended substitutes carry Active product status, ensuring long-term availability and manufacturing support.
Compliance Certification: ROHS3 compliance across all active alternatives indicates adherence to current environmental and safety standards.
Electrical Compatibility: All through-hole 8-DIP alternatives maintain the dual-circuit, general-purpose amplifier configuration with compatible supply voltage ranges and output current specifications.

Frequently Asked Questions (FAQ)

Q: Can the LM358SNG be directly replaced with LM358AN/NOPB?

A: Yes. The LM358AN/NOPB is a direct pin-compatible replacement. Both devices feature identical electrical specifications (45 nA input bias current, 2 mV input offset voltage), operate across the same 3V to 32V supply range, and are packaged in 8-DIP through-hole configuration. The primary difference is product status: LM358AN/NOPB is active with ROHS3 compliance, while LM358SNG is obsolete.

Q: What is the difference between LM358P and LM358AN/NOPB?

A: Both are active Texas Instruments products in 8-DIP packages. LM358P features improved input bias current (20 nA vs. 45 nA) and lower supply current (500 µA vs. 1 mA). However, LM358P has a maximum supply voltage of 30V compared to 32V for LM358AN/NOPB. For applications operating at or near 32V, LM358AN/NOPB is the appropriate choice.

Q: Why is the LM358DR2G listed as a substitute if it uses a different package?

A: LM358DR2G is included as a functional equivalent for applications undergoing PCB redesign or modernization to surface-mount technology. It maintains identical electrical specifications to the LM358SNG but requires PCB layout modification. It is not suitable for direct socket replacement in through-hole designs.

Q: Can I use CA3240AEZ as a replacement in all applications?

A: CA3240AEZ is electrically compatible but has two important limitations: (1) minimum supply voltage is 4V instead of 3V, making it unsuitable for 3V-only applications, and (2) supply current is significantly higher (8 mA vs. 500 µA), which may impact power budget in battery-powered designs. Verify supply voltage requirements and power consumption constraints before selection.

Q: What is the advantage of LF353N/NOPB over LM358AN/NOPB?

A: LF353N/NOPB uses J-FET input technology, providing extremely low input bias current (50 pA vs. 45 nA) and higher slew rate (13 V/µs). These characteristics are beneficial for high-impedance signal sources and fast-transient applications. However, LF353N/NOPB requires a minimum 10V supply voltage, restricting use in 3V to 9V applications where LM358AN/NOPB operates.

Q: Is AS358P-E1 suitable for extended temperature range applications?

A: Yes. AS358P-E1 operates across -40°C to 85°C, compared to 0°C to 70°C for LM358SNG. It maintains pin-for-pin compatibility in 8-DIP package and features improved input bias current (20 nA). It is suitable for industrial and automotive applications requiring broader temperature operation.

Q: What does ROHS3 compliance indicate?

A: ROHS3 compliance indicates the device meets the Restriction of Hazardous Substances Directive 3, confirming the absence of lead, mercury, cadmium, hexavalent chromium, and specified brominated flame retardants. All active substitute parts listed carry ROHS3 compliance, ensuring compatibility with modern procurement and environmental standards.

Q: Can I use BA15218 in a 3V supply application?

A: No. BA15218 requires a minimum supply voltage of 4V. It is not suitable for applications operating at 3V. For 3V operation, select from LM358AN/NOPB, LM358N/NOPB, LM358P, LM258P, or AS358P-E1.

Q: How do I determine which substitute is best for my application?

A: Identify your critical parameters: (1) required supply voltage range, (2) operating temperature range, (3) input bias current sensitivity, (4) output current requirements, and (5) PCB mounting technology (through-hole or surface-mount). Cross-reference these requirements against the Parameter Comparison table. All listed substitutes maintain the dual-circuit, general-purpose amplifier function; selection depends on specific application constraints.
