LM392DRG4 Equivalent & Substitute Parts

Part Overview

The LM392DRG4 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 LM392DRG4 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent substitute components for ongoing design support and procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM392DRG4 is determined by strict alignment of the following parameters:

Critical Substitution Criteria:

• Base product number (LM392)
• Device type (Amplifier, Comparator)
• Package configuration (8-SOIC with 3.90mm width)
• Mounting type (Surface Mount)
• Application category (Transducer Amplifier)
• Compliance certifications (RoHS3, REACH Unaffected)
• Moisture sensitivity level (MSL 1)

The LM392DRG4 differs from its substitute only in packaging format. The primary part uses individual tube packaging (DRG4 suffix), while the substitute utilizes tape and reel (TR) packaging. Both variants contain identical die and electrical specifications, making them functionally interchangeable at the component level.

Parameter Comparison

Engineering Selection Recommendations

The LM392DR is the direct substitute for the LM392DRG4. Both components share identical electrical specifications, die configuration, and compliance certifications. The LM392DR maintains active product status with Texas Instruments and demonstrates higher inventory availability (7066 units in stock versus 2100 units for the main part).

Selection of the LM392DR is appropriate for applications requiring the LM392DRG4 specification. The packaging format difference (tape and reel versus tube) affects only procurement and assembly processes, not electrical performance or board-level compatibility. The 8-SOIC package footprint remains identical, permitting direct PCB layout substitution.

Both components satisfy ROHS3 compliance and REACH requirements. Moisture sensitivity level MSL 1 indicates unlimited shelf life under standard storage conditions for both variants.

Frequently Asked Questions (FAQ)

Q: Can the LM392DR be used as a direct replacement for the LM392DRG4 on a PCB?

A: Yes. Both components utilize identical 8-SOIC package geometry with 3.90mm width and surface mount configuration. Pin assignments, electrical specifications, and functional characteristics are identical. Direct PCB substitution is permissible without layout modification.

Q: What is the difference between the DRG4 and DR packaging designations?

A: The DRG4 suffix indicates tube packaging format, while the DR suffix indicates tape and reel (TR) packaging format. Both contain the same integrated circuit die and electrical specifications. The packaging difference affects only component handling and assembly processes.

Q: Are there compliance or certification differences between LM392DRG4 and LM392DR?

A: No. Both components carry identical RoHS3 compliance status and REACH Unaffected designation. Moisture sensitivity level is MSL 1 for both variants, indicating unlimited shelf life under standard storage conditions.

Q: Why is the LM392DRG4 discontinued while the LM392DR remains active?

A: Product discontinuation at distribution channels typically reflects market demand patterns and inventory management decisions. The LM392DR remains in active production by Texas Instruments and is available through authorized distributors.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching base product number (LM392), device type (Amplifier, Comparator), package configuration (8-SOIC 3.90mm), mounting type (Surface Mount), application category (Transducer Amplifier), and compliance certifications (RoHS3, REACH Unaffected).
