Key Parameters

Substitute Part Grouping Explanation

Substitution for the LM392DR2G is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 8-SOIC (0.154", 3.90mm Width) surface mount package to ensure direct PCB footprint compatibility.

Functional Classification: Substitute parts must be classified as Amplifier, Comparator ICs or General Purpose Amplifiers capable of transducer amplification applications.

Compliance Requirements: All substitutes must maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status to meet regulatory and environmental standards.

Mounting Technology: Surface mount technology is required for all substitutes to maintain assembly process compatibility.

The LM392DR2G has direct equivalents within the LM392 base product family from Texas Instruments, as well as functional alternatives in the TL062 J-FET amplifier series and LM1458 general purpose amplifier series. These alternatives share the same package footprint and compliance certifications while offering different electrical characteristics suited to specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Recommended Primary Substitutes):

LM392M/NOPB and LM392MX/NOPB are direct functional equivalents of the LM392DR2G, sharing identical type classification (Amplifier, Comparator) and transducer amplifier applications. Both parts are manufactured by Texas Instruments and maintain the same 8-SOIC (0.154", 3.90mm Width) package footprint. LM392M/NOPB carries Active product status with full availability, making it the preferred primary substitute. LM392MX/NOPB is available in Cut Tape and Digi-Reel packaging formats and also maintains Active status.

Secondary Alternatives (Functional Substitutes):

TL062ACDR is an Active product offering J-FET amplifier technology in the identical 8-SOIC (0.154", 3.90mm Width) package. This part provides alternative electrical characteristics suitable for applications requiring lower input bias current and higher slew rate performance.

LM1458M/NOPB is a General Purpose Amplifier with 2-circuit configuration in the same 8-SOIC (0.154", 3.90mm Width) package, maintaining Active product status. This part is suitable for applications where general-purpose amplification meets functional requirements.

Compliance Verification:

All recommended substitutes maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status, ensuring regulatory and environmental standard alignment with the original LM392DR2G specification.

Packaging Consideration:

TL062ACPSR uses an 8-SOIC (0.209", 5.30mm Width) package variant and is classified as Last Time Buy. This part requires PCB footprint verification before selection, as the wider package may not be compatible with existing LM392DR2G layouts.

Frequently Asked Questions (FAQ)

Q: Can LM392M/NOPB be used as a direct replacement for LM392DR2G?

A: Yes. LM392M/NOPB is a direct functional equivalent manufactured by Texas Instruments. Both parts share identical type classification (Amplifier, Comparator), transducer amplifier applications, and 8-SOIC (0.154", 3.90mm Width) package footprint. LM392M/NOPB maintains Active product status with established supply availability.

Q: What is the difference between LM392M/NOPB and LM392MX/NOPB?

A: Both parts are functionally identical Amplifier, Comparator ICs with the same 8-SOIC (0.154", 3.90mm Width) package and Active product status. The primary difference is packaging format: LM392M/NOPB is supplied in Tube packaging, while LM392MX/NOPB is supplied in Cut Tape and Digi-Reel formats. Selection depends on procurement and assembly requirements.

Q: Can TL062ACDR replace LM392DR2G in all applications?

A: TL062ACDR shares the same 8-SOIC (0.154", 3.90mm Width) package footprint and compliance certifications. However, it is classified as a J-FET Amplifier rather than an Amplifier, Comparator. Application compatibility depends on whether the circuit requires comparator functionality or if general amplification meets functional requirements. Electrical characteristics differ, including slew rate (3.5V/µs vs. unspecified for LM392DR2G) and input bias current (30 pA vs. unspecified).

Q: Is TL062ACPSR compatible with existing LM392DR2G PCB layouts?

A: TL062ACPSR uses an 8-SOIC (0.209", 5.30mm Width) package, which differs from the LM392DR2G standard 8-SOIC (0.154", 3.90mm Width) package. PCB footprint verification is required before selection. This part is also classified as Last Time Buy, indicating limited future availability.

Q: What compliance certifications do all substitute parts maintain?

A: All recommended substitute parts maintain ROHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), and REACH Unaffected status, matching the original LM392DR2G specifications.

Q: Why is LM392M listed as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer has announced end-of-life for this product. While currently available, procurement should prioritize Active status alternatives such as LM392M/NOPB or LM392MX/NOPB for long-term design support.

Q: Can LM1458M/NOPB be used for transducer amplifier applications?

A: LM1458M/NOPB is classified as a General Purpose Amplifier with 2-circuit configuration in the 8-SOIC (0.154", 3.90mm Width) package. It shares the same package footprint and compliance certifications as the LM392DR2G. Application compatibility depends on whether general-purpose amplification meets functional requirements, as this part is not specifically designated for transducer amplifier applications.
