LM358ADG4 Equivalent & Substitute Parts

Part Overview

The LM358ADG4 is a general-purpose operational amplifier featuring two independent circuits in an 8-SOIC surface-mount package, manufactured by Texas Instruments. This device is classified as obsolete, though 1,467 units remain in stock as new original inventory. The LM358ADG4 operates across a supply voltage range of 3V to 30V with a slew rate of 0.3V/µs and a gain bandwidth product of 1.1 MHz, making it suitable for general analog signal processing applications.

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

Engineering Selection Recommendations

Primary Recommendation: Texas Instruments LM358 Series (Active Status)

The LM358AM/NOPB, LM358AMX/NOPB, LM358M/NOPB, and LM358MX/NOPB represent the direct active-production equivalents to the obsolete LM358ADG4. All four variants share identical electrical specifications and maintain the same 8-SOIC package footprint. These parts are manufactured by the original equipment supplier, ensuring design continuity and long-term availability. All variants are ROHS3 compliant and carry REACH unaffected status. Selection between these four options depends on packaging preference: tube packaging (AM/NOPB, M/NOPB) or cut tape with Digi-Reel (AMX/NOPB, MX/NOPB). The MX/NOPB variant offers the highest inventory level at 74,281 units.

Secondary Recommendation: UMW LM358ADR (Active Status)

The LM358ADR from UMW provides an active-status alternative with identical output current capability (40 mA) and input offset voltage (2 mV). This part extends the maximum supply voltage to 36V and operates across an expanded temperature range (-25°C to 85°C). The 8-SOIC package maintains mechanical compatibility. Inventory availability is substantial at 115,100 units. This option is suitable when extended supply voltage headroom or wider operating temperature range is required.

Tertiary Recommendation: onsemi LM258DR2G (Active Status)

The LM258DR2G from onsemi operates as a functional alternative with 1.0 MHz gain bandwidth product and 40 mA output current per channel. The part maintains 8-SOIC package compatibility and operates across -25°C to 85°C. Supply voltage range is 3V to 32V. Inventory is extensive at 505,200 units, providing excellent long-term availability. This option is appropriate for applications where extended temperature operation is beneficial.

Alternative Consideration: Rohm Semiconductor BA10358F-E2 and BA2904 Series (Active Status)

The Rohm BA10358F-E2 and BA2904 series represent functional alternatives with 8-SOP package configuration. These parts meet the 3V to 32V supply requirement and maintain 2 mV input offset voltage. However, output current per channel is reduced to 20 mA (BA10358F-E2) or 30 mA (BA2904F-E2, BA2904SF-E2), which falls below the LM358ADG4 specification of 40 mA. These options are suitable only for applications where output current demand does not exceed the specified limits. The BA2904SF-E2 offers the widest operating temperature range (-40°C to 105°C).

Compliance and Certification:

All recommended substitute parts maintain ROHS3 compliance and carry REACH unaffected status, matching the original LM358ADG4 regulatory posture. All parts are classified as EAR99 for export control purposes.

Frequently Asked Questions (FAQ)

Q1: Can I directly replace LM358ADG4 with LM358AM/NOPB without circuit modification?

Yes. The LM358AM/NOPB is electrically and mechanically compatible with the LM358ADG4. Both parts feature identical pin configuration in 8-SOIC package, matching supply voltage range (3V to 32V for the AM variant, 3V to 30V for the ADG4), and identical output current capability (40 mA per channel). The primary difference is product status: the ADG4 is obsolete while the AM is active production. No circuit redesign is required.

Q2: What is the difference between LM358AMX/NOPB and LM358AM/NOPB?

The electrical specifications are identical. The difference is packaging format: LM358AM/NOPB is supplied in tube packaging, while LM358AMX/NOPB is supplied in cut tape with Digi-Reel format. Selection depends on your assembly process requirements. Both maintain the same 8-SOIC package footprint.

Q3: Why do some substitute parts show lower output current (20 mA or 30 mA) compared to the LM358ADG4 (40 mA)?

Output current capability is a fundamental electrical specification determined by the internal circuit design. The Rohm BA10358F-E2 series and BA2904 series are designed with lower output current limits. These parts are suitable only for applications where the circuit design does not require the full 40 mA output current per channel. If your application requires 40 mA output capability, select parts from the Texas Instruments LM358 series, UMW LM358ADR, or onsemi LM258DR2G.

Q4: Can I use LM258DR2G in place of LM358ADG4?

Yes, with the following considerations: The LM258DR2G maintains 40 mA output current per channel and operates across 3V to 32V supply range, meeting the critical electrical requirements. The 8-SOIC package is mechanically identical. However, the LM258DR2G operates across -25°C to 85°C, which extends below the LM358ADG4 operating range (0°C to 70°C). This is not a limitation for most applications; it represents an expanded capability. Verify that your circuit design does not depend on the narrower temperature range of the original part.

Q5: What is the significance of the 8-SOIC versus 8-SOP package designation?

Both 8-SOIC and 8-SOP refer to surface-mount packages with eight pins. The primary difference is package body width: 8-SOIC is 0.154" (3.90mm) wide, while 8-SOP is typically 0.173" (4.40mm) wide. These dimensions affect PCB layout and component density. If your PCB layout is designed for the narrower 8-SOIC footprint, select parts explicitly specified as 8-SOIC (LM358 series, LM258DR2G, LM358ADR). The Rohm BA10358 and BA2904 series use the wider 8-SOP package and may not fit existing PCB layouts designed for 8-SOIC.

Q6: Is the UMW LM358ADR a genuine Texas Instruments part?

No. The UMW LM358ADR is manufactured by UMW (United Microelectronics Corporation), not Texas Instruments. UMW is an independent semiconductor manufacturer. The part number similarity to the Texas Instruments LM358 series reflects functional equivalence and cross-compatibility, not common origin. UMW parts are legitimate active-production alternatives suitable for applications where multi-source component strategy is required.

Q7: Which substitute part offers the best long-term availability?

The onsemi LM258DR2G currently shows the highest inventory level at 505,200 units, followed by the Texas Instruments LM358MX/NOPB at 74,281 units. Both parts are in active production status, indicating ongoing manufacturing commitment. For long-term design security, either option provides substantial availability. The Texas Instruments variants offer the advantage of original manufacturer sourcing, while the onsemi option provides the largest current inventory buffer.

Q8: Do all substitute parts maintain the same slew rate as the LM358ADG4?

No. The LM358ADG4 specifies 0.3V/µs slew rate. The Texas Instruments LM358 series variants do not specify slew rate in the provided data. The Rohm BA10358 and BA2904 series specify 0.2V/µs, which is lower than the original part. The onsemi LM258DR2G does not specify slew rate. If your circuit design depends on the 0.3V/µs slew rate specification, verify that the selected substitute part meets this requirement through detailed datasheet review or contact the manufacturer directly.

Q9: Can I use BA2904SF-E2 for applications requiring operation above 85°C?

The BA2904SF-E2 operates across -40°C to 105°C, which covers temperatures up to 105°C. This part is suitable for applications requiring operation up to 105°C. However, output current per channel is specified at 30 mA, which is below the LM358ADG4 specification of 40 mA. Verify that your application does not require the full 40 mA output current capability before selecting this part.

Q10: Are all substitute parts RoHS3 compliant?

Yes. All substitute parts listed in this reference document are explicitly marked as ROHS3 compliant, matching the compliance status of the original LM358ADG4. All parts also carry REACH unaffected status. No compliance risk exists when transitioning from the obsolete LM358ADG4 to any of the recommended substitute parts.
