LM358DG4 Equivalent & Substitute Parts

Part Overview

The LM358DG4 is a general-purpose operational amplifier manufactured by Texas Instruments, featuring dual circuits in an 8-SOIC surface mount package. This device is classified as obsolete, indicating it is no longer in active production. The LM358DG4 operates across a supply voltage range of 3V to 30V with a gain bandwidth product of 700 kHz and a slew rate of 0.3V/µs, making it suitable for general analog signal processing applications.

Due to its obsolete status, component sourcing for new designs requires identification of functionally equivalent alternatives that maintain electrical compatibility while offering active production status or extended availability.

Substitute Part Grouping Explanation

Substitution of the LM358DG4 is determined by strict electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

Dual-circuit general-purpose operational amplifier topology
Supply voltage range encompassing the original 3V to 30V specification
Input bias current within acceptable tolerance (20 nA baseline)
Output current capability of 40 mA per channel minimum
Slew rate and gain bandwidth product suitable for the intended application frequency range

Mechanical Compatibility Criteria:

8-SOIC surface mount package with 0.154" (3.90mm) width
Pin configuration and footprint compatibility
Moisture sensitivity level MSL 1 (Unlimited)

Compliance Requirements:

ROHS3 compliance maintained
REACH unaffected status
EAR99 export classification

Substitute parts are grouped into two categories: direct pin-compatible replacements maintaining identical electrical specifications, and functionally equivalent alternatives with enhanced performance characteristics suitable for new designs.

Engineering Selection Recommendations

For Direct Replacement (Obsolete Stock Continuation):

The LM358DR from Rohm Semiconductor provides the closest electrical match to the LM358DG4, maintaining identical slew rate (0.3V/µs) and gain bandwidth product (700 kHz) specifications. Both devices share the same 8-SOIC package footprint and pin configuration. The LM358DR is classified as "Not For New Designs," indicating limited future availability but current stock of 825,200 units. This option is suitable for sustaining production of existing designs where component specifications are locked.

For New Design Implementation (Active Production):

The LM358AM/NOPB, LM358AMX/NOPB, LM358M/NOPB, and LM358MX/NOPB variants from Texas Instruments are all classified as Active products with full production support. These devices offer enhanced gain bandwidth product (1 MHz versus 700 kHz), providing improved frequency response characteristics. All variants maintain the 8-SOIC package compatibility and meet ROHS3 compliance requirements. The primary trade-offs are increased input bias current (45 nA versus 20 nA) and higher supply current consumption (1 mA versus 500 µA). Selection between tube and cut tape packaging depends on assembly process requirements.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification, ensuring regulatory alignment with the original LM358DG4.

Frequently Asked Questions (FAQ)

Q: Can the LM358AM/NOPB directly replace the LM358DG4 in existing circuit designs?

A: The LM358AM/NOPB is pin-compatible and functionally equivalent for general-purpose amplifier applications. However, the increased gain bandwidth product (1 MHz versus 700 kHz) and higher input bias current (45 nA versus 20 nA) may affect circuit performance in precision applications. Circuit validation is necessary for designs with tight offset voltage or frequency response specifications.

Q: What is the difference between LM358AMX/NOPB and LM358AM/NOPB?

A: Both devices are electrically identical. The primary difference is packaging: LM358AM/NOPB is supplied in tube packaging, while LM358AMX/NOPB is supplied in cut tape with Digi-Reel format. Selection depends on assembly equipment compatibility and volume requirements.

Q: Why does the LM358DR have lower inventory than the Texas Instruments alternatives?

A: The LM358DR is classified as "Not For New Designs," indicating Rohm Semiconductor is transitioning away from this product line. Despite higher current inventory (825,200 units), future availability cannot be guaranteed. Texas Instruments active products (LM358AM/NOPB variants) offer long-term supply security.

Q: Is the LM358DR suitable for new product development?

A: The LM358DR is not recommended for new designs due to its "Not For New Designs" status. Active alternatives such as LM358AM/NOPB or LM358MX/NOPB provide equivalent functionality with assured long-term availability and manufacturer support.

Q: What are the key electrical differences between the LM358DG4 and LM358AM/NOPB?

A: The LM358AM/NOPB offers higher gain bandwidth product (1 MHz versus 700 kHz), lower input offset voltage (2 mV versus 3 mV), but higher input bias current (45 nA versus 20 nA) and supply current (1 mA versus 500 µA). The maximum supply voltage is increased from 30V to 32V, providing slightly wider operating range.

Q: Are all substitute parts available in the same 8-SOIC package?

A: Yes. All substitute parts listed maintain the 8-SOIC surface mount package with 0.154" (3.90mm) width, ensuring mechanical and footprint compatibility with the original LM358DG4 design.

Q: What is the operating temperature range difference, and does it matter?

A: The LM358DG4 operates from 0°C to 70°C, while LM358DR extends to -40°C to 85°C. For applications requiring extended temperature operation, the LM358DR or other extended-range alternatives are necessary. Standard commercial temperature range (0°C to 70°C) is maintained across all Texas Instruments active variants.
