LM258NG Equivalent & Substitute Parts

Part Overview

The LM258NG is a general-purpose operational amplifier featuring two independent circuits in an 8-PDIP through-hole package, manufactured by onsemi. This device is classified as obsolete, though 907 pieces remain in stock. The LM258NG operates across a wide supply voltage range of 3V to 32V with a gain-bandwidth product of 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 availability, and production planning. Active alternatives with compatible electrical and mechanical specifications are available from multiple manufacturers.

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible, Identical Specifications):

LM258AP (Texas Instruments) is the primary recommended substitute. It maintains identical 8-DIP through-hole packaging, general-purpose amplifier classification, dual-circuit configuration, and compatible supply voltage range (3V to 32V). The device is in active production status with ROHS3 compliance. Operating temperature range matches the original specification (-25°C to 85°C). Current consumption is lower (500µA vs. 800µA per channel), and input bias current is superior (15 nA vs. 45 nA), making it a direct functional upgrade.

AS358AP-E1 and AS358P-E1 (Diodes Incorporated) provide equivalent functionality with enhanced specifications. Both maintain 8-DIP through-hole packaging and general-purpose amplifier architecture. Supply voltage range extends to 36V maximum (vs. 32V), and operating temperature extends to -40°C minimum. Input bias current is lower (20 nA). These devices are in active production with ROHS3 compliance and high inventory availability (44,266 and 67,400 units respectively).

For Surface-Mount Applications:

LM258DR2G (onsemi) provides identical electrical specifications to the original LM258NG in 8-SOIC surface-mount packaging. This substitution is appropriate only for designs transitioning to SMD assembly. The device is in active production status with extensive inventory (505,200 units).

For Enhanced Performance Requirements:

CA3240AEZ (Renesas Electronics Corporation) offers superior input bias current (10 pA vs. 45 nA) and higher gain-bandwidth product (4.5 MHz vs. 1 MHz) while maintaining 8-DIP through-hole packaging and general-purpose amplifier classification. Supply voltage range extends to 36V maximum. This device is suitable for applications requiring lower input offset drift and higher frequency response.

BA15218 (Rohm Semiconductor) provides 10 MHz gain-bandwidth product with 8-DIP through-hole packaging. Operating temperature range extends to -40°C. This device is appropriate for applications requiring higher bandwidth performance.

For Fixed Supply Voltage Applications:

LM1458N/NOPB (Texas Instruments) is restricted to fixed ±18V dual supply operation (36V total span). This device is not suitable for variable supply voltage applications but offers 1 MHz gain-bandwidth product matching the original specification. Operating temperature range is limited to 0°C to 70°C.

Devices Not Recommended for Direct Substitution:

AD812ANZ, AD826ANZ, and AD828ANZ are specialized feedback amplifiers with different electrical characteristics and application profiles. These devices are not pin-compatible replacements and require circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can LM258AP directly replace LM258NG without circuit modification?

A: Yes. LM258AP maintains identical pin configuration, 8-DIP through-hole package, dual general-purpose amplifier architecture, and compatible supply voltage range (3V to 32V). Operating temperature range is identical (-25°C to 85°C). The device is in active production status, ensuring long-term availability.

Q: What is the difference between LM258NG and LM258DR2G?

A: Both devices share identical electrical specifications and are manufactured by onsemi. The primary difference is packaging: LM258NG uses 8-DIP through-hole mounting, while LM258DR2G uses 8-SOIC surface-mount packaging. LM258DR2G is in active production with significantly higher inventory availability (505,200 units vs. 907 units for LM258NG).

Q: Are AS358AP-E1 and AS358P-E1 interchangeable?

A: Yes. Both devices are manufactured by Diodes Incorporated with identical electrical specifications, 8-DIP through-hole packaging, and general-purpose amplifier classification. The primary difference is packaging format (tube vs. tube), which does not affect electrical performance. Both are in active production status.

Q: Why would I choose CA3240AEZ over LM258AP?

A: CA3240AEZ offers superior input bias current (10 pA vs. 15 nA in LM258AP and 45 nA in LM258NG) and higher gain-bandwidth product (4.5 MHz vs. 700 kHz in LM258AP). These characteristics reduce input offset drift and enable higher frequency operation. CA3240AEZ is appropriate for precision analog signal processing applications where input bias current and frequency response are critical parameters.

Q: Can I use AD828ANZ as a substitute for LM258NG?

A: AD828ANZ is not recommended as a direct substitute. While it maintains 8-DIP through-hole packaging and dual-circuit configuration, it is classified as a voltage feedback video amplifier with significantly different electrical characteristics. AD828ANZ requires minimum 5V single supply (vs. 3V for LM258NG) and is optimized for high-frequency video applications rather than general-purpose analog signal processing.

Q: What is the minimum supply voltage for each substitute part?

A: LM258NG, LM258DR2G, LM258AP, AS358AP-E1, and AS358P-E1 all support 3V minimum supply voltage. BA15218, CA3240AEZ, and AD826ANZ require 4V minimum. AD812ANZ and AD828ANZ require 2.4V (single supply) or ±1.2V (dual supply). LM1458N/NOPB requires fixed ±18V dual supply.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed are ROHS3 compliant except LM258NG (original part, obsolete status) and LM258AP (MSL status listed as Not Applicable). All active substitute parts carry ROHS3 compliance certification.

Q: What is the operating temperature range for each substitute?

A: LM258NG and LM258AP operate across -25°C to 85°C. AS358AP-E1, AS358P-E1, BA15218, CA3240AEZ, and AD826ANZ extend to -40°C minimum. LM1458N/NOPB is limited to 0°C to 70°C. AD812ANZ and AD828ANZ do not specify operating temperature range in provided data.

Q: Which substitute offers the lowest input bias current?

A: CA3240AEZ provides the lowest input bias current at 10 pA, compared to 45 nA in LM258NG. This characteristic is beneficial for high-impedance input applications where input bias current drift affects measurement accuracy.

Q: Can I use LM1458N/NOPB in a variable supply voltage application?

A: No. LM1458N/NOPB is restricted to fixed ±18V dual supply operation (36V total span). It is not suitable for applications requiring variable supply voltage. LM258AP, AS358AP-E1, AS358P-E1, BA15218, and CA3240AEZ support variable supply voltage ranges and are appropriate for such applications.
