LM392MX Equivalent & Substitute Parts

Part Overview

The LM392MX is a linear amplifier and comparator integrated circuit manufactured by Texas Instruments, designed for transducer amplifier applications. The device is packaged in an 8-SOIC surface mount configuration with a 3.90mm width. The LM392MX is classified as an obsolete product, which necessitates identification of equivalent substitute components for ongoing design support and procurement continuity. Active equivalent parts maintain identical electrical and mechanical specifications while offering current manufacturing status and improved compliance certifications.

Substitute Part Grouping Explanation

Substitution of the LM392MX is determined by strict equivalence across the following parameters:

Electrical Equivalence Criteria:

• Identical base product number (LM392)
• Matching device type classification (Amplifier, Comparator)
• Identical application category (Transducer Amplifier)

Mechanical Equivalence Criteria:

• Identical package type (8-SOIC)
• Identical package dimensions (0.154", 3.90mm Width)
• Identical mounting type (Surface Mount)

Environmental & Compliance Criteria:

• Matching Moisture Sensitivity Level (MSL 1)
• Identical ECCN and HTSUS classifications
• REACH status equivalence

The substitute part LM392MX/NOPB maintains full equivalence across all specified parameters while offering active product status and enhanced RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The LM392MX/NOPB is the direct equivalent substitute for the obsolete LM392MX. Both components share identical electrical specifications, mechanical packaging, and environmental classifications. The primary distinction is product lifecycle status: the LM392MX is obsolete, while the LM392MX/NOPB maintains active manufacturing status from Texas Instruments.

The LM392MX/NOPB additionally provides ROHS3 compliance, whereas the original LM392MX is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic component procurement in regulated industries.

Both parts are classified as MSL 1 (Unlimited moisture sensitivity), indicating no special moisture handling requirements during storage or assembly operations.

Frequently Asked Questions (FAQ)

Q: Can LM392MX/NOPB be used as a direct replacement for LM392MX?

A: Yes. The LM392MX/NOPB is a direct equivalent substitute. Both components share identical electrical characteristics, package specifications (8-SOIC, 3.90mm width), mounting type (surface mount), and application classification (transducer amplifier). The primary difference is product status: LM392MX/NOPB is active, while LM392MX is obsolete.

Q: What does the "/NOPB" suffix indicate?

A: The "/NOPB" suffix designates the packaging configuration as Cut Tape (CT) and Digi-Reel® format, with Tape & Reel (TR) availability. This is a standard Texas Instruments packaging designation and does not affect electrical or mechanical compatibility.

Q: Are there any compliance differences between these parts?

A: Yes. The LM392MX/NOPB is ROHS3 compliant, while the LM392MX is RoHS non-compliant. Both parts maintain identical REACH Unaffected status and EAR99 export classification. The improved RoHS compliance of the LM392MX/NOPB aligns with current procurement standards.

Q: Do these components require special moisture handling?

A: No. Both the LM392MX and LM392MX/NOPB are classified as MSL 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage, handling, or assembly.

Q: Is the 8-SOIC package footprint identical between both parts?

A: Yes. Both components use the 8-SOIC package with 0.154" width (3.90mm). PCB footprints and assembly processes are fully compatible.
