AP358NG-U Equivalent & Substitute Parts

Part Overview

The AP358NG-U is a general-purpose operational amplifier manufactured by Diodes Incorporated, configured as a 2-circuit differential output device in an 8-DIP package. This part is classified as obsolete, which necessitates identification of active equivalent and substitute components for new designs and ongoing production requirements. The AP358NG-U operates across a wide supply voltage range (3V to 32V) and is suitable for general-purpose amplification applications requiring moderate bandwidth and low input bias current characteristics.

Substitute Part Grouping Explanation

Substitution of the AP358NG-U is determined by compatibility across the following critical parameters:

Package and Mounting: All substitute parts must use 8-DIP (0.300", 7.62mm) through-hole packaging to ensure mechanical and electrical compatibility with existing PCB layouts.

Amplifier Configuration: All substitutes must be general-purpose operational amplifiers with 2 circuits per package to maintain functional equivalence.

Supply Voltage Range: Substitute parts must support the minimum 3V supply requirement and accommodate the maximum 32V supply specification of the original design.

Output Current Capability: All substitutes must deliver a minimum of 40 mA per output channel to satisfy load-driving requirements.

Electrical Performance: Substitutes are grouped based on gain-bandwidth product (1 MHz or lower), input bias current (45 nA or lower), and input offset voltage (2 mV or lower) to ensure functional compatibility in existing circuit topologies.

Product Status and Compliance: Active product status is preferred for long-term availability. All substitutes maintain ROHS3 compliance and REACH unaffected status consistent with the original part.

Engineering Selection Recommendations

Direct Electrical Equivalents (Highest Compatibility):

The LM358AN/NOPB and LM358N/NOPB are direct electrical equivalents to the AP358NG-U. These parts maintain identical specifications across gain-bandwidth product (1 MHz), input bias current (45 nA), input offset voltage (2 mV), supply current (1 mA), and output current (40 mA). Both operate across the full 3V to 32V supply range and share the 0°C to 70°C operating temperature window. Both parts are active products with ROHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory compliance.

Functional Equivalents with Enhanced Performance (Lower Supply Current):

The LM358AP and LM358P offer functional equivalence with reduced supply current consumption (0.5 mA versus 1 mA). These parts maintain the 40 mA output current capability and 3V minimum supply voltage. The LM358AP operates to 30V maximum supply, while the LM358P also operates to 30V maximum. Both are active products with ROHS3 compliance. The LM358AP exhibits lower input bias current (15 nA) and maintains 2 mV input offset voltage. The LM358P shows 20 nA input bias current and 3 mV input offset voltage. These parts are suitable for applications where reduced power consumption is beneficial.

Extended Temperature Range Alternatives:

The LM258AP and LM258P extend the operating temperature range to -25°C to 85°C while maintaining 3V to 32V supply voltage compatibility. The LM258AP provides 15 nA input bias current and 2 mV input offset voltage. The LM258P provides 20 nA input bias current and 3 mV input offset voltage. Both deliver 40 mA output current and operate at 0.5 mA supply current. These parts are active products with ROHS3 compliance and are suitable for applications requiring extended temperature operation.

Constrained Substitutes (Limited Compatibility):

The MC1458P maintains 1 MHz gain-bandwidth product but requires a minimum 10V supply voltage, exceeding the AP358NG-U's 3V minimum requirement. Output current is limited to 25 mA per channel, below the 40 mA specification. Supply current consumption is elevated at 3.4 mA. This part is suitable only for applications with 10V or higher supply voltages and lower output current requirements.

The TL022CP operates at 10V minimum supply voltage and delivers only 6 mA output current per channel, making it unsuitable for applications requiring the full 40 mA output current specification. This part is not recommended as a substitute for the AP358NG-U.

The NJM3404AD requires a minimum 4V supply voltage and delivers 30 mA output current per channel, below the 40 mA requirement. This part is suitable only for applications with 4V or higher supply voltages and lower output current demands.

Frequently Asked Questions (FAQ)

Q: Can the LM358AN/NOPB directly replace the AP358NG-U without circuit modifications?

A: Yes. The LM358AN/NOPB is a direct electrical equivalent with identical specifications for gain-bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range. The 8-DIP package is mechanically identical. No circuit modifications are required.

Q: What is the primary advantage of using LM358AP or LM358P instead of LM358AN/NOPB?

A: The LM358AP and LM358P reduce supply current consumption from 1 mA to 0.5 mA per channel, resulting in lower power dissipation. This is beneficial in battery-powered or power-constrained applications. Both maintain the 40 mA output current capability and 3V minimum supply voltage. The trade-off is a maximum supply voltage of 30V instead of 32V.

Q: Are the LM258AP and LM258P suitable for applications requiring operation below 0°C?

A: Yes. The LM258AP and LM258P extend the operating temperature range to -25°C to 85°C, making them suitable for applications requiring sub-zero operation. Both maintain 3V to 32V supply voltage compatibility and 40 mA output current capability. These parts are active products with full ROHS3 compliance.

Q: Why is the MC1458P not recommended as a direct substitute?

A: The MC1458P requires a minimum 10V supply voltage, which exceeds the AP358NG-U's 3V minimum requirement. Additionally, output current is limited to 25 mA per channel, below the 40 mA specification. This part is suitable only for applications with 10V or higher supply voltages and lower output current demands.

Q: What is the significance of the "Last Time Buy" status for LM358PE3?

A: Last Time Buy status indicates that the manufacturer has announced end-of-life for this part. While currently available, future availability is not guaranteed. For new designs, active products such as LM358AN/NOPB, LM358AP, or LM258AP are preferred to ensure long-term supply continuity.

Q: Can the TL022CP replace the AP358NG-U in existing designs?

A: No. The TL022CP requires a minimum 10V supply voltage and delivers only 6 mA output current per channel, both of which fall below the AP358NG-U specifications. This part is not suitable as a substitute.

Q: Are all substitute parts ROHS3 compliant?

A: All recommended substitute parts (LM358AN/NOPB, LM358N/NOPB, LM358AP, LM358P, LM358PE3, LM258AP, LM258P) are ROHS3 compliant. The MC1458P and NJM3404AD are also ROHS3 compliant. All parts maintain REACH unaffected status.

Q: What is the difference between the LM358AP and LM358P in terms of input bias current?

A: The LM358AP exhibits 15 nA input bias current, while the LM358P exhibits 20 nA input bias current. Both maintain 2 mV and 3 mV input offset voltage respectively. The LM358AP is preferred for applications sensitive to input bias current effects.

Q: Can the NJM3404AD be used in applications requiring 40 mA output current per channel?

A: No. The NJM3404AD delivers 30 mA output current per channel, which is below the 40 mA requirement of the AP358NG-U. This part is suitable only for applications with lower output current demands.

Q: What packaging options are available for substitute parts?

A: All substitute parts are available in 8-DIP (0.300", 7.62mm) through-hole packaging, maintaining mechanical compatibility with the AP358NG-U. Packaging variations (Tube, Box) refer to shipping and handling formats and do not affect electrical or mechanical compatibility.
