LM258D Equivalent & Substitute Parts
Part Overview
The LM258D is a general-purpose operational amplifier manufactured by Texas Instruments, packaged in 8-SOIC surface mount configuration. This device integrates two independent amplifier circuits suitable for a wide range of analog signal processing applications. The LM258D is classified as obsolete, indicating that Texas Instruments has discontinued active production and support. For new designs or replacement inventory, equivalent and substitute parts from active product lines are necessary to ensure long-term supply chain reliability and continued technical support.

Engineering Selection Recommendations
For Direct Replacement (Recommended Primary Choice):
The LM358 series (LM358AM/NOPB, LM358M/NOPB, LM358AMX/NOPB, LM358MX/NOPB) from Texas Instruments provides the most straightforward substitution path. These parts are active-status products with identical 8-SOIC packaging, matching voltage supply range (3 V to 32 V), and equivalent output current capability (40 mA per channel). All variants maintain ROHS3 compliance and MSL Level 1 rating. The primary difference is packaging format: tube packaging (AM/M variants) versus cut tape and Digi-Reel® (AMX/MX variants). Selection between these variants depends on procurement and assembly requirements rather than electrical performance.
For Extended Temperature Range Applications:
The AD706 series (AD706ARZ, AD706ARZ-REEL, AD706ARZ-REEL7, AD706JRZ) from Analog Devices extends the operating temperature range to -40°C to 85°C (ARZ variants) or 0°C to 70°C (JRZ variant). These parts maintain 8-SOIC packaging and voltage supply compatibility (4 V to 36 V). Input bias current is significantly lower (50 pA versus 20 nA), and input offset voltage is reduced (30 µV versus 3 mV). Output current per channel is 15 mA, which is lower than the LM258D specification of 40 mA. Selection of AD706 variants is appropriate when extended temperature operation and improved input characteristics are required, provided that the 15 mA output current limit is acceptable for the application.
For High-Performance Applications:
The ADA4000-2ARZ (J-FET amplifier) offers superior input bias current (5 pA) and significantly higher slew rate (20 V/µs) compared to the LM258D. This part is suitable for applications requiring very low input bias current and fast transient response. Operating temperature range extends to -40°C to 125°C. Minimum supply voltage is 8 V, which is higher than the LM258D specification of 3 V. Output current per channel is 28 mA, lower than the LM258D specification of 40 mA.
The ADA4004-2ARZ-RL (iPolar® series) provides the highest gain bandwidth product (12 MHz) and slew rate (2.7 V/µs) among all substitute options. Operating temperature range extends to -40°C to 125°C. Minimum supply voltage is 10 V. Output current per channel is 10 mA, which is significantly lower than the LM258D specification. This part is appropriate for applications requiring high-speed signal processing within the specified supply voltage and output current constraints.
Compliance and Regulatory Considerations:
All substitute parts listed maintain ROHS3 compliance and MSL Level 1 (unlimited moisture sensitivity) rating, matching the LM258D specifications. All parts carry EAR99 ECCN classification and REACH Unaffected status. Procurement of any substitute part does not introduce additional regulatory or compliance burden.
Frequently Asked Questions (FAQ)
Q1: Can the LM358 series directly replace the LM258D without circuit modification?
A: The LM358 series is electrically compatible with the LM258D within the specified operating parameters. Both devices are general-purpose dual operational amplifiers in 8-SOIC packaging with identical pin configuration. The primary electrical differences are lower input bias current (45 nA versus 20 nA) and lower input offset voltage (2 mV versus 3 mV) in the LM358, which represent improvements. Operating temperature range differs: LM358 operates 0°C to 70°C versus LM258D at -25°C to 85°C. If your application operates within the LM358 temperature range, direct substitution is possible without circuit modification.
Q2: What is the significance of the different LM358 packaging variants (AM, AMX, M, MX)?
A: The LM358 series is available in four packaging variants that differ only in delivery format and quantity per reel. LM358AM/NOPB and LM358M/NOPB are supplied in tube packaging. LM358AMX/NOPB and LM358MX/NOPB are supplied in cut tape and Digi-Reel® format. The electrical specifications and 8-SOIC package dimensions are identical across all four variants. Selection depends on your procurement process and assembly equipment compatibility, not on electrical performance.
Q3: Why does the AD706 series show lower output current (15 mA) compared to the LM258D (40 mA)?
A: The AD706 is designed for applications requiring very low input bias current (50 pA) and improved input offset voltage (30 µV). The reduced output current specification reflects the design optimization for precision signal conditioning rather than high-current driving capability. If your application requires 40 mA output current per channel, the AD706 is not suitable. The LM358 series maintains the 40 mA output current specification and is the appropriate choice for such applications.
Q4: When should I select the ADA4000-2ARZ J-FET amplifier instead of general-purpose alternatives?
A: The ADA4000-2ARZ is a J-FET input amplifier with extremely low input bias current (5 pA) and high slew rate (20 V/µs). Select this part when your application requires very low input bias current to minimize errors in high-impedance signal sources, or when fast transient response is critical. The trade-off is higher minimum supply voltage (8 V versus 3 V for LM258D) and lower output current (28 mA versus 40 mA). Verify that your power supply and output current requirements are compatible before selection.
Q5: What is the iPolar® series designation for the ADA4004-2ARZ-RL, and does it affect compatibility?
A: iPolar® is an Analog Devices product series designation indicating optimized performance characteristics. The ADA4004-2ARZ-RL is a general-purpose dual operational amplifier with enhanced gain bandwidth product (12 MHz) and slew rate (2.7 V/µs). The iPolar® designation does not affect pin compatibility or 8-SOIC package dimensions. However, the minimum supply voltage is 10 V, which is higher than the LM258D specification of 3 V. Verify that your power supply can provide 10 V minimum before selecting this part.
Q6: Are all substitute parts available in the same 8-SOIC package as the LM258D?
A: Yes. All substitute parts listed in this document are packaged in 8-SOIC (0.154", 3.90mm Width) configuration, matching the LM258D package dimensions and pin configuration. This ensures mechanical and electrical compatibility with existing PCB layouts and sockets designed for the LM258D.
Q7: Do substitute parts maintain the same RoHS and REACH compliance as the LM258D?
A: Yes. All substitute parts listed maintain ROHS3 compliance and REACH Unaffected status, matching the LM258D specifications. All parts carry EAR99 ECCN classification. Substitution does not introduce additional regulatory or compliance requirements.
Q8: What is the practical difference between the LM358 and AD706 for general-purpose applications?
A: For general-purpose applications operating within 0°C to 70°C temperature range and requiring 40 mA output current per channel, the LM358 is the recommended choice. It maintains identical output current capability and voltage supply range as the LM258D. The AD706 is appropriate when extended temperature operation (-40°C to 85°C) and improved input characteristics (lower bias current and offset voltage) are required, provided that the 15 mA output current limit is acceptable.
