LM392N Equivalent & Substitute Parts

Part Overview

The LM392N is a linear amplifier and comparator integrated circuit manufactured by Texas Instruments, designed for transducer amplifier applications. The device is packaged in an 8-DIP (0.300", 7.62mm) through-hole configuration and is classified as obsolete. Due to its obsolete product status, identifying functionally equivalent substitute parts is essential for design continuity, procurement planning, and system maintenance. The LM392N/NOPB represents the active production equivalent with enhanced compliance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM392N is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Base Product Number: LM392
• Device Type: Amplifier, Comparator
• Package / Case: 8-DIP (0.300", 7.62mm)
• Supplier Device Package: 8-PDIP
• Mounting Type: Through Hole
• Application: Transducer Amplifier
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected
• ECCN: EAR99
• HTSUS Code: 8542.33.0001

The LM392N/NOPB qualifies as a direct substitute because it maintains identical electrical specifications, mechanical packaging, and application requirements while offering active product status and improved regulatory compliance.

Engineering Selection Recommendations

LM392N/NOPB Selection Criteria:

The LM392N/NOPB is the direct substitute for the obsolete LM392N based on the following engineering factors:

1. Product Status: The LM392N/NOPB maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete LM392N.

2. Regulatory Compliance: The LM392N/NOPB achieves ROHS3 compliance, whereas the original LM392N is RoHS non-compliant. This compliance upgrade is significant for applications subject to environmental regulations and procurement standards.

3. Functional Equivalence: Both devices share identical electrical specifications, base product number (LM392), device type (Amplifier, Comparator), and application classification (Transducer Amplifier).

4. Mechanical Compatibility: Both parts utilize the 8-DIP (0.300", 7.62mm) through-hole package with 8-PDIP supplier device package designation, ensuring direct PCB compatibility without layout modifications.

5. Packaging: The LM392N/NOPB is supplied in tube packaging, which is standard for active production components and facilitates automated assembly processes.

6. Regulatory Alignment: Both parts maintain identical REACH status (REACH Unaffected), ECCN (EAR99), and HTSUS classification (8542.33.0001), ensuring consistent export and import compliance.

Frequently Asked Questions (FAQ)

Q: Can the LM392N/NOPB be used as a direct replacement for the LM392N in existing designs?

A: Yes. The LM392N/NOPB is a direct substitute. Both devices share identical electrical specifications, package dimensions (8-DIP, 0.300", 7.62mm), mounting type (through-hole), and application classification (transducer amplifier). No circuit modifications or PCB redesign is required.

Q: What is the significance of the "/NOPB" suffix in the LM392N/NOPB part number?

A: The "/NOPB" suffix indicates "No Plumbum" (lead-free) configuration and is associated with RoHS3 compliance. This designation reflects the manufacturing process and environmental compliance level of the component.

Q: Why is the LM392N classified as obsolete?

A: The LM392N is classified as obsolete due to its RoHS non-compliant status and the availability of the functionally equivalent LM392N/NOPB, which meets current environmental and regulatory standards. Texas Instruments has transitioned production to the compliant variant.

Q: Are there any electrical performance differences between the LM392N and LM392N/NOPB?

A: No electrical performance differences exist between the two devices. Both are amplifier and comparator ICs with identical functional specifications for transducer amplifier applications.

Q: What is the moisture sensitivity level (MSL) for both parts?

A: Both the LM392N and LM392N/NOPB have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can the LM392N/NOPB be used in applications requiring RoHS compliance?

A: Yes. The LM392N/NOPB is ROHS3 compliant, making it suitable for applications and procurement environments with RoHS requirements. The original LM392N is not RoHS compliant.

Q: Are both parts subject to export control restrictions?

A: Both the LM392N and LM392N/NOPB are classified under ECCN EAR99, which is a general classification for most commercial electronic components with minimal export control restrictions.
