LM1458N Equivalent & Substitute Parts

Part Overview

The LM1458N is a general-purpose operational amplifier featuring dual circuits in an 8-DIP package, manufactured by Texas Instruments. This device is classified as obsolete, indicating it has been discontinued and is no longer recommended for new designs. The LM1458N operates across a wide supply voltage range of 36 V and is suitable for applications requiring dual-channel amplification with moderate performance specifications. Due to its obsolete status, equivalent and substitute parts are necessary for ongoing maintenance, legacy system support, and new design implementations requiring similar functional characteristics.

Substitute Part Grouping Explanation

Substitution of the LM1458N is determined by strict alignment of electrical and mechanical parameters. The following criteria establish valid substitute relationships:

Primary Substitution Criteria:

Amplifier Type: General Purpose (required match)
Number of Circuits: 2 (required match)
Package / Case: 8-DIP form factor (required match)
Mounting Type: Through Hole (required match)
Voltage - Supply Span: Must accommodate 36 V maximum supply
Operating Temperature: Must support 0°C to 70°C minimum range

Secondary Performance Parameters:

Slew Rate: 0.5 V/µs or greater
Gain Bandwidth Product: 1 MHz or greater
Current - Input Bias: 200 nA or lower
Voltage - Input Offset: 1 mV or lower
Current - Supply: 3 mA per channel or lower

Substitute parts are grouped into two categories: Direct Equivalents (matching all primary criteria with identical or superior performance) and Functional Alternatives (meeting primary criteria with performance variations in specific parameters).

Engineering Selection Recommendations

Direct Equivalent (Recommended for Replacement):

LM1458N/NOPB is the primary substitute for LM1458N. This part maintains identical electrical specifications and mechanical packaging while offering active product status and ROHS3 compliance. The transition from the obsolete LM1458N to LM1458N/NOPB requires no circuit redesign and provides regulatory compliance for new manufacturing.

Active Alternatives with Extended Performance:

LT1469CN8#PBF and LT1469IN8#PBF offer significantly enhanced performance characteristics including 22 V/µs slew rate and 90 MHz gain bandwidth product. These parts are suitable for applications requiring higher speed operation. However, the reduced supply voltage span (5 to 9 V maximum) restricts their use to systems operating within this range. Both variants are ROHS3 compliant and carry active product status.

Low-Power Alternative:

OP200GPZ provides the lowest supply current consumption at 0.57 mA per channel, making it suitable for battery-powered or power-constrained applications. This part maintains the 36 V maximum supply capability and offers extended operating temperature range (-40°C to 85°C). ROHS3 compliance is confirmed.

Legacy Compatibility:

NJM4558D carries "Not For New Designs" status but remains in production with high inventory availability. This part is suitable only for legacy system maintenance where original performance characteristics are required. RoHS compliance is confirmed.

Restricted Substitution:

AD708JNZ and TS358CD C3G do not fully meet the supply voltage requirements of the original LM1458N. AD708JNZ operates with minimum 6 V supply, and TS358CD C3G operates with maximum 32 V supply. These parts are suitable only for applications where the reduced voltage range is acceptable.

Frequently Asked Questions (FAQ)

Q: Can LM1458N/NOPB be used as a direct replacement for LM1458N?

A: Yes. LM1458N/NOPB is electrically and mechanically identical to LM1458N, with the primary difference being active product status and ROHS3 compliance. No circuit modifications are required.

Q: What is the key difference between LT1469CN8#PBF and LT1469IN8#PBF?

A: Both parts share identical electrical specifications. The primary difference is operating temperature range: LT1469CN8#PBF operates 0°C to 70°C, while LT1469IN8#PBF operates -40°C to 85°C. Selection depends on the required temperature specification for the application.

Q: Why does OP200GPZ have lower supply current than LM1458N?

A: OP200GPZ is designed for low-power applications with supply current of 0.57 mA per channel compared to LM1458N's 3 mA. This reduced current consumption comes with trade-offs in slew rate (0.15 V/µs versus 0.5 V/µs) and gain bandwidth product (0.5 MHz versus 1 MHz).

Q: Can LT1469 series parts replace LM1458N in all applications?

A: No. LT1469 series parts operate with maximum 9 V supply voltage, while LM1458N operates up to 36 V. Substitution is valid only for applications operating within the 5 to 9 V range. For applications requiring 36 V supply capability, LM1458N/NOPB or OP200GPZ are appropriate choices.

Q: Is NJM4558D suitable for new product designs?

A: No. NJM4558D carries "Not For New Designs" status and should be used only for legacy system maintenance and repair. For new designs, select from parts with "Active" product status: LM1458N/NOPB, LT1469 series, OP200GPZ, or TS358CD C3G.

Q: What is the significance of RoHS compliance in selecting a substitute?

A: RoHS compliance is mandatory for products manufactured for sale in regulated markets. LM1458N is RoHS non-compliant, making it unsuitable for new manufacturing. All recommended substitutes (LM1458N/NOPB, LT1469 series, OP200GPZ, TS358CD C3G) are ROHS3 compliant.

Q: Does package size differ between substitute parts?

A: All substitute parts use 8-DIP through-hole packaging with 0.300" (7.62mm) pitch, except TS358CD C3G which uses 0.309" (7.87mm) pitch. This minor dimensional difference is typically accommodated by standard DIP sockets and PCB layouts.

Q: Which substitute offers the best overall performance?

A: LT1469 series parts offer the highest performance with 22 V/µs slew rate and 90 MHz gain bandwidth product. However, performance selection must align with application requirements and supply voltage constraints. For general-purpose replacement maintaining original specifications, LM1458N/NOPB is appropriate.
