LM358N Equivalent & Substitute Parts

Part Overview

The LM358N is a general-purpose operational amplifier manufactured by STMicroelectronics, configured as a dual-circuit device in an 8-Mini DIP package. This component is classified as obsolete, though 17,468 units remain in stock as new original inventory. The LM358N operates across a supply voltage range of 3V to 30V with a slew rate of 0.6V/µs and a gain bandwidth product of 700 kHz, making it suitable for general-purpose amplification applications requiring moderate bandwidth performance.

Due to its obsolete product status, identifying equivalent and substitute parts is necessary for ongoing design support, production continuity, and long-term component availability. Active alternatives with compatible electrical and mechanical specifications are available from multiple manufacturers.

Substitute Part Grouping Explanation

Substitution of the LM358N is determined by strict alignment of electrical and mechanical parameters. The following criteria establish valid substitution relationships:

Primary Substitution Criteria:

Dual-circuit general-purpose operational amplifier configuration
8-DIP (0.300", 7.62mm) through-hole package
Input bias current: 20 nA (±25 nA tolerance acceptable)
Input offset voltage: 2 mV to 3 mV
Output current per channel: 40 mA minimum
Supply voltage range: minimum 3V, maximum 30V or greater
ROHS3 compliance and unlimited moisture sensitivity level (MSL 1)

Secondary Compatibility Factors:

Slew rate: 0.3V/µs to 0.6V/µs for direct replacement
Gain bandwidth product: 700 kHz to 1 MHz for functional equivalence
Operating temperature: 0°C to 70°C (automotive grade preferred)
Supply current: 500µA to 1mA per channel acceptable

Substitute parts are grouped into two categories: Direct Equivalents (matching all primary criteria) and Functional Alternatives (meeting primary criteria with enhanced performance specifications).

Engineering Selection Recommendations

Direct Replacement (Preferred for Pin-Compatible Substitution):

The LM358P and LM358AP from Texas Instruments are the primary direct replacements for the LM358N. Both devices maintain identical package geometry (8-DIP), dual-circuit configuration, and core electrical specifications. LM358AP offers superior input bias current performance (15 nA versus 20 nA) while maintaining the same 700 kHz gain bandwidth product and 0°C to 70°C operating range. Both are ROHS3 compliant with active product status and extensive inventory availability (20,100 and 53,800 units respectively).

Extended Temperature Range Alternatives:

The AS358AP-E1 and AS358P-E1 from Diodes Incorporated provide identical electrical specifications to the LM358N with extended operating temperature range (-40°C to 85°C) and higher maximum supply voltage (36V versus 30V). These devices are suitable for applications requiring broader environmental performance while maintaining the same input bias current (20 nA) and input offset voltage (2 mV). Product status is active with high inventory levels (44,266 and 67,400 units).

Enhanced Performance Alternatives:

The CA3240AEZ from Renesas Electronics offers significantly improved performance characteristics including lower input bias current (10 pA), higher slew rate (9V/µs), and greater gain bandwidth product (4.5 MHz). This device is suitable for applications where the LM358N's performance is marginal. Extended temperature range (-40°C to 85°C) and higher supply voltage capability (36V) are additional benefits. Product status is active with 1,744 units in stock.

High-Speed Alternatives:

The LT1208CN8#PBF from Linear Technology and LT1211ACN8#PBF from Analog Devices provide substantially higher slew rates (400V/µs and 7V/µs respectively) and gain bandwidth products (45 MHz and 14 MHz). These devices are appropriate for applications requiring significantly faster signal processing. Both maintain 8-DIP package compatibility and are ROHS3 compliant. Selection between these options depends on specific bandwidth and slew rate requirements.

Compliance and Certification:

All recommended substitutes maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The LM358N carries automotive grade qualification (AEC-Q100), which is not explicitly stated for all substitutes. For automotive applications, verification of equivalent qualification status is necessary prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the LM358P be used as a direct replacement for the LM358N?

A: Yes. The LM358P is a direct pin-compatible replacement. Both devices use the 8-DIP package, contain dual operational amplifier circuits, and operate across the same supply voltage range (3V to 30V). Electrical specifications are nearly identical, with LM358P offering slightly lower supply current (500µA versus 700µA per channel). The LM358P is active product status with extensive inventory availability.

Q: What is the difference between LM358AP and LM358P?

A: Both are Texas Instruments LM358 variants in 8-DIP packages with identical package geometry and dual-circuit configuration. LM358AP features lower input bias current (15 nA versus 20 nA) and is specified for the same 0°C to 70°C operating temperature range. LM358P has input bias current of 20 nA. Both maintain 700 kHz gain bandwidth product and 40 mA output current per channel. Selection depends on input bias current requirements for specific applications.

Q: Are the Diodes Incorporated AS358 variants suitable replacements?

A: Yes. The AS358AP-E1 and AS358P-E1 are functionally equivalent to the LM358N with identical input bias current (20 nA) and input offset voltage (2 mV). Key advantages include extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) and higher maximum supply voltage (36V versus 30V). Both devices are ROHS3 compliant with active product status and high inventory levels.

Q: When should the CA3240AEZ be selected over the LM358N?

A: The CA3240AEZ is appropriate when application requirements exceed the LM358N's performance envelope. This device provides lower input bias current (10 pA), higher slew rate (9V/µs), and significantly greater gain bandwidth product (4.5 MHz). Extended temperature range (-40°C to 85°C) and higher supply voltage capability (36V) are additional benefits. The CA3240AEZ is suitable for precision instrumentation and high-speed signal processing applications.

Q: What are the trade-offs when using high-speed alternatives like LT1208CN8#PBF?

A: High-speed alternatives such as the LT1208CN8#PBF offer substantially higher slew rates (400V/µs) and gain bandwidth products (45 MHz), enabling faster signal processing. However, these devices typically exhibit higher input bias current (4 µA for LT1208CN8#PBF) and greater supply current consumption (7mA per channel). Selection should be based on specific bandwidth and slew rate requirements, as higher performance typically correlates with increased power consumption and cost.

Q: Is the LM358N/NOPB equivalent to the LM358N?

A: The LM358N/NOPB is a Texas Instruments variant with identical package and dual-circuit configuration. However, electrical specifications differ: input bias current is 45 nA (versus 20 nA), gain bandwidth product is 1 MHz (versus 700 kHz), and supply current is 1mA (versus 700µA per channel). The LM358N/NOPB is suitable for applications where these performance differences are acceptable. Product status is active with 2,224 units in stock.

Q: Can substitutes be used in automotive applications originally designed for LM358N?

A: The LM358N carries automotive grade qualification (AEC-Q100). Not all substitutes explicitly state equivalent automotive qualification. For automotive applications, verification of AEC-Q100 qualification or equivalent automotive-grade certification is necessary prior to implementation. The AS358 variants from Diodes Incorporated and CA3240AEZ from Renesas are suitable for extended temperature automotive environments, though specific qualification status should be confirmed with manufacturers.

Q: What packaging considerations apply to these substitutes?

A: All listed substitutes maintain the 8-DIP (0.300", 7.62mm) through-hole package format, ensuring mechanical compatibility with existing PCB layouts and socket configurations. Mounting type is through-hole for all devices. No PCB redesign is required for package accommodation. Verify that the specific variant selected (e.g., AS358AP-E1 versus AS358P-E1) matches the intended application requirements before procurement.
