LM358H Equivalent & Substitute Parts

Part Overview

The LM358H is a general-purpose operational amplifier featuring two independent circuits in a TO-99-8 metal can package. Manufactured by Texas Instruments, this device is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The LM358H operates across a wide supply voltage range of 3 V to 32 V and is suitable for applications requiring low input bias current and moderate output drive capability.

Substitute Part Grouping Explanation

Substitution of the LM358H is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 2
• Gain Bandwidth Product: 1 MHz
• Current - Input Bias: 45 nA
• Voltage - Input Offset: 2 mV
• Current - Supply: 1 mA
• Current - Output / Channel: 40 mA
• Voltage - Supply Span: 3 V to 32 V
• Operating Temperature Range: 0°C to 70°C

Mechanical Equivalence Criteria:

• Package / Case: TO-99-8 Metal Can
• Mounting Type: Through Hole

The LM358H/NOPB is identified as a direct substitute based on identical electrical specifications and mechanical packaging. The primary distinction is product status and regulatory compliance, not functional performance.

Parameter Comparison

Engineering Selection Recommendations

The LM358H/NOPB serves as the direct functional equivalent to the LM358H. Both devices are manufactured by Texas Instruments and exhibit identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The LM358H is classified as obsolete, while the LM358H/NOPB maintains active product status. For new designs and ongoing procurement, the LM358H/NOPB is the appropriate selection to ensure long-term component availability and supply chain continuity.

Regulatory Compliance: The LM358H/NOPB is ROHS3 compliant and REACH unaffected, whereas the LM358H is RoHS non-compliant. Applications subject to regulatory requirements for hazardous substance restrictions require the LM358H/NOPB.

Packaging and Inventory: Both devices are supplied in TO-99-8 metal can through-hole packages. The LM358H/NOPB is available in bulk packaging, while the original LM358H is no longer actively stocked in new inventory quantities.

Frequently Asked Questions (FAQ)

Q: Can the LM358H/NOPB be used as a direct replacement for the LM358H in existing designs?

A: Yes. The LM358H/NOPB is electrically and mechanically identical to the LM358H. All electrical parameters, including gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range, are equivalent. The TO-99-8 metal can package and through-hole mounting are identical.

Q: What is the significance of the "/NOPB" suffix in the LM358H/NOPB part number?

A: The "/NOPB" suffix indicates that the device is supplied without lead (Pb), reflecting RoHS3 compliance. This designation distinguishes the part from legacy versions and confirms adherence to hazardous substance restrictions.

Q: Why is the LM358H classified as obsolete?

A: The LM358H has been superseded by the LM358H/NOPB, which maintains identical functionality while meeting current regulatory compliance standards. Texas Instruments has transitioned production to the compliant variant.

Q: Are there any performance differences between the LM358H and LM358H/NOPB?

A: No. Both devices exhibit identical electrical performance across all specified parameters. The differences are limited to product status, packaging designation, and regulatory compliance certifications.

Q: What is the operating temperature range for both devices?

A: Both the LM358H and LM358H/NOPB operate across 0°C to 70°C. This range applies to all electrical specifications and performance guarantees.

Q: Can these devices be used in applications requiring extended temperature ranges?

A: No. The specified operating temperature range is 0°C to 70°C. Applications requiring operation outside this range require alternative device selection.

Q: What is the maximum supply voltage for the LM358H and LM358H/NOPB?

A: The maximum supply voltage span is 32 V for both devices. The minimum supply voltage is 3 V. Operation outside this range is not specified.

Q: How many independent operational amplifier circuits are integrated in these devices?

A: Both devices contain two independent general-purpose operational amplifier circuits in a single TO-99-8 metal can package.
