Substitute Part Grouping Explanation
Substitution of the LM1458M is determined by strict adherence to the following electrical and mechanical parameters:
Primary Substitution Criteria:
- Amplifier Type: General Purpose
- Number of Circuits: 2
- Package / Case: 8-SOIC (0.154", 3.90mm Width)
- Mounting Type: Surface Mount
- Voltage - Supply Span: Minimum 10 V, Maximum 30 V or greater
- Current - Output / Channel: 20 mA or greater
- Operating Temperature Range: Must encompass 0°C to 70°C
Secondary Compatibility Parameters:
- Slew Rate: 0.5 V/µs or greater
- Gain Bandwidth Product: 1 MHz or greater
- Current - Input Bias: 80 nA or lower
- Voltage - Input Offset: 2 mV or lower
Substitute parts are grouped into two categories:
Direct Equivalents (Same Base Specifications): Parts that maintain identical or near-identical electrical performance characteristics, including slew rate, gain bandwidth product, and input bias current. These parts are pin-compatible and functionally interchangeable within the same operating conditions.
Functional Alternatives (Enhanced Performance): Parts that exceed the LM1458M specifications in one or more parameters (higher slew rate, higher gain bandwidth product, lower input offset voltage) while maintaining compatibility with the primary substitution criteria. These parts provide improved performance and are suitable for applications where the LM1458M specifications are minimum requirements.

Engineering Selection Recommendations
Recommended Primary Substitute: MC1458DR
The MC1458DR manufactured by Texas Instruments is the recommended primary substitute for the LM1458M. This part maintains identical electrical specifications including slew rate (0.5 V/µs), gain bandwidth product (1 MHz), and input bias current (80 nA). The MC1458DR is currently in active production status, ensuring long-term availability and supply chain continuity. Both parts operate within the 0°C to 70°C temperature range and are housed in the same 8-SOIC package. The MC1458DR provides superior output current capability (25 mA versus 20 mA) and lower input offset voltage (1 mV versus 2 mV), making it a direct functional upgrade. RoHS3 compliance and REACH unaffected status confirm regulatory alignment with modern manufacturing standards.
Secondary Substitute: MC33078DR2G
The MC33078DR2G from onsemi is suitable for applications requiring enhanced performance. This part exceeds the LM1458M specifications in slew rate (7 V/µs), gain bandwidth product (16 MHz), and output current capability (37 mA). The MC33078DR2G maintains the same 8-SOIC package and supports the full 10 V to 36 V supply range. Extended operating temperature range (-40°C to 85°C) provides additional thermal margin. This substitute is appropriate for designs where improved frequency response and faster signal settling are beneficial without requiring circuit redesign.
Alternative Substitute: SE5532AD8R2G
The SE5532AD8R2G from onsemi offers the widest operating temperature range (-55°C to 125°C) and highest supply voltage maximum (40 V). This part is suitable for applications requiring extended environmental performance. The slew rate (9 V/µs) and gain bandwidth product (10 MHz) exceed LM1458M specifications. The 8-SOIC package maintains mechanical compatibility. This substitute is recommended for industrial and automotive applications where temperature extremes are encountered.
Package Consideration: Rohm Semiconductor BA4560F-E2
The BA4560F-E2 from Rohm Semiconductor provides a functionally equivalent alternative with enhanced performance (4 V/µs slew rate, 10 MHz gain bandwidth product). This part is housed in an 8-SOP package (0.173", 4.40mm width) rather than the standard 8-SOIC (0.154", 3.90mm width).

A: The ADA4062-2ARZ is a specialized J-FET input operational amplifier designed for applications requiring extremely low input bias current (2 pA). While it maintains the 8-SOIC package and supports the required supply voltage range, it is optimized for precision measurement and high-impedance input circuits rather than general-purpose signal processing.
Q: What compliance certifications should I verify when selecting a substitute?
A: Verify RoHS3 compliance status and REACH unaffected designation. All recommended substitutes listed in this document maintain RoHS3 compliance and REACH unaffected status, ensuring alignment with modern manufacturing and environmental regulations.
Q: Can the SE5532AD8R2G be used in applications with temperature extremes?
A: Yes. The SE5532AD8R2G operates across an extended temperature range of -55°C to 125°C, compared to the LM1458M range of 0°C to 70°C. This part is suitable for industrial and automotive applications where temperature extremes are encountered. The 8-SOIC package and supply voltage range (6 V to 40 V) provide additional design flexibility.
Q: What is the significance of the supply voltage span difference between substitutes?
A: The LM1458M supports a supply voltage span of 10 V to 36 V. Some substitutes, such as the SE5532AD8R2G, support a wider range (6 V to 40 V), providing additional design flexibility for applications with varying power supply requirements.
