LM358DRG4 Equivalent & Substitute Parts

Part Overview

The LM358DRG4 is a general-purpose operational amplifier manufactured by Texas Instruments, configured as a dual-channel (2 circuit) device in 8-SOIC surface mount packaging. This part is classified as Obsolete, indicating it is no longer in active production. The LM358DRG4 operates across a supply voltage range of 3V to 30V and is suitable for applications requiring low-power, general-purpose amplification in compact form factors.

Due to its obsolete status, identifying functionally equivalent substitute parts is necessary for design continuity, procurement flexibility, and long-term supply chain reliability. Substitute parts must maintain electrical compatibility within the specified parameter tolerances and physical compatibility with the 8-SOIC package footprint.

Substitution Categories:

Category 1 – Direct Electrical Equivalents (Active Status) Parts meeting or exceeding all electrical specifications with Active product status. These include LM358AM/NOPB, LM358AMX/NOPB, LM358M/NOPB, and LM358MX/NOPB from Texas Instruments, and LM358DR2G from onsemi. These parts feature enhanced gain bandwidth product (1 MHz vs. 700 kHz) and are suitable for new designs.

Category 2 – Functional Equivalents (Not For New Designs) The LM358DR from Rohm Semiconductor provides electrical equivalence with specifications closely matching the LM358DRG4, including 0.3V/µs slew rate and 700 kHz gain bandwidth product. Product status is "Not For New Designs," indicating limited availability for future procurement.

Category 3 – Package Variant Substitutes (8-SOP) Parts BA10358F-E1, BA10358F-E2, and BA2904F-E2 from Rohm Semiconductor use an 8-SOP package (0.173", 4.40mm width) instead of 8-SOIC. These represent mechanical package variants with similar electrical functionality but require PCB footprint redesign.

Engineering Selection Recommendations

For Active Production Designs: Select LM358MX/NOPB or LM358AMX/NOPB from Texas Instruments. Both parts carry Active product status, ensuring long-term availability and supply chain continuity. These variants are available in Cut Tape (CT) & Digi-Reel® packaging with inventory exceeding 2,000 units. The enhanced gain bandwidth product of 1 MHz provides improved frequency response compared to the obsolete LM358DRG4.

For Existing Designs Requiring Direct Replacement: LM358DR2G from onsemi provides the closest electrical match with 1 MHz gain bandwidth product and Active status. This part is available in high volume (492,200 units) and maintains the 8-SOIC package footprint without PCB redesign. Supply voltage range extends to 32V, exceeding the original 30V maximum.

For Legacy System Support: LM358DR from Rohm Semiconductor maintains the original 700 kHz gain bandwidth product and 0.3V/µs slew rate, ensuring behavioral equivalence with the LM358DRG4. However, "Not For New Designs" status indicates limited future availability. This option is suitable only for repair and maintenance of existing systems.

For Package-Variant Applications: BA10358F-E2 from Rohm Semiconductor offers Active status with 8-SOP packaging. This option requires PCB footprint modification but provides extended operating temperature range (-40°C to 85°C) and high inventory availability (150,300 units).

All recommended substitutes maintain ROHS3 compliance, MSL Level 1 (Unlimited), and EAR99 export classification consistent with the original LM358DRG4.

Frequently Asked Questions (FAQ)

Q: Can LM358AM/NOPB directly replace LM358DRG4 without circuit modification?

A: Yes. Both parts are dual-channel general-purpose operational amplifiers in 8-SOIC packaging with identical pinout. The LM358AM/NOPB operates within the same 3V to 32V supply range and provides 40 mA output current per channel. The enhanced 1 MHz gain bandwidth product (versus 700 kHz) represents an improvement that does not require circuit redesign. Verify that your application does not depend on the specific 0.3V/µs slew rate of the original part.

Q: What is the difference between LM358MX/NOPB and LM358M/NOPB?

A: Both parts are electrically identical with Active status and identical electrical specifications. The difference is packaging format: LM358MX/NOPB is supplied in Cut Tape (CT) & Digi-Reel® format suitable for automated assembly, while LM358M/NOPB is supplied in Tube format suitable for manual handling and lower-volume applications. Inventory availability is significantly higher for LM358MX/NOPB (74,281 units vs. 4,180 units).

Q: Why does LM358DR from Rohm have "Not For New Designs" status?

A: "Not For New Designs" indicates the manufacturer has discontinued active promotion and development support for this part. While functionally equivalent to LM358DRG4 with matching 700 kHz gain bandwidth product, Rohm recommends using alternative parts for new circuit designs. This part remains suitable for replacement in existing systems where supply is available (825,200 units in stock).

Q: Can BA10358F-E2 substitute for LM358DRG4 without PCB changes?

A: No. BA10358F-E2 uses 8-SOP packaging (0.173", 4.40mm width) instead of 8-SOIC (0.154", 3.90mm width). The package footprint is physically different and requires PCB redesign. However, electrical functionality is compatible: dual-channel general-purpose amplifier with 40 mA output current and 3V to 32V supply range. This option is suitable only when PCB modification is feasible.

Q: What is the impact of higher gain bandwidth product (1 MHz vs. 700 kHz) on circuit performance?

A: Higher gain bandwidth product indicates faster frequency response and improved transient performance. For applications designed around the original 700 kHz specification, the 1 MHz variants (LM358AM/NOPB, LM358MX/NOPB, LM358DR2G) will not cause functional problems. However, if your circuit includes frequency-dependent compensation networks or relies on specific phase margin characteristics, verify stability through simulation or testing.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All recommended substitute parts carry ROHS3 Compliant status and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original LM358DRG4. All parts are REACH Unaffected and classified as EAR99 for export purposes.

Q: Which substitute offers the best long-term supply availability?

A: LM358MX/NOPB from Texas Instruments offers the highest inventory (74,281 units) combined with Active product status, ensuring continued manufacturing and supply chain support. LM358DR2G from onsemi is the second option with 492,200 units in stock and Active status.
