Substitute Part Grouping Explanation

Substitution of the LMC6081-MDA is determined by electrical and functional equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Slew Rate: 1.5 V/µs
• Gain Bandwidth Product: 1.3 MHz
• Current - Input Bias: 0.01 pA
• Voltage - Input Offset: 150 µV
• Current - Supply: 550 µA
• Voltage - Supply Span: 4.5 V to 15.5 V
• Operating Temperature Range: -40°C to 85°C

Mechanical and Compliance Criteria:

• Base Product Number: LMC6081
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The LMC6081IMX/NOPB qualifies as a direct electrical substitute, maintaining identical electrical specifications while differing in packaging format (8-SOIC versus Diesale).

Parameter Comparison

Engineering Selection Recommendations

The LMC6081IMX/NOPB is electrically and functionally equivalent to the LMC6081-MDA across all specified operational parameters. Both devices are manufactured by Texas Instruments, share the same base product number (LMC6081), and maintain identical electrical characteristics including slew rate, gain bandwidth product, input bias current, and supply voltage specifications.

The primary distinction between these parts is packaging format: the LMC6081-MDA is supplied as a die in Diesale format, while the LMC6081IMX/NOPB is packaged in 8-SOIC surface-mount configuration. This packaging difference necessitates corresponding changes to PCB layout, assembly processes, and interconnection methods.

Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and environmental compatibility. The LMC6081IMX/NOPB carries Active product status with higher inventory availability (6731 pieces) compared to the Last Time Buy status of the LMC6081-MDA (664 pieces).

Selection between these parts depends on application-specific packaging requirements and assembly capabilities. Die-level integration (LMC6081-MDA) is appropriate for hybrid circuit applications, while 8-SOIC packaging (LMC6081IMX/NOPB) is suitable for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the LMC6081IMX/NOPB directly replace the LMC6081-MDA in existing designs?

A: Electrical substitution is complete; all operational parameters are identical. However, physical substitution requires PCB redesign due to packaging format differences. The LMC6081-MDA is a die component, while the LMC6081IMX/NOPB is an 8-SOIC surface-mount package. Assembly and interconnection methods must be modified accordingly.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by matching: amplifier type (General Purpose), circuit count (1), output type (Rail-to-Rail), slew rate (1.5 V/µs), gain bandwidth product (1.3 MHz), input bias current (0.01 pA), input offset voltage (150 µV), supply current (550 µA), and supply voltage range (4.5 V to 15.5 V). All these parameters are identical between the main part and substitute.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both the LMC6081-MDA and LMC6081IMX/NOPB maintain ROHS3 compliance, MSL Level 1 (Unlimited) moisture sensitivity rating, and identical REACH and ECCN classifications. Regulatory and environmental requirements are equivalent.

Q: What is the significance of the Last Time Buy status for the LMC6081-MDA?

A: Last Time Buy designation indicates that the LMC6081-MDA is no longer in active production. Existing inventory (664 pieces) represents the final available supply. The LMC6081IMX/NOPB, with Active status and higher inventory (6731 pieces), represents the ongoing production alternative for long-term supply continuity.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate across the identical temperature range of -40°C to 85°C, ensuring thermal compatibility in equivalent applications.

Q: What packaging considerations apply to the LMC6081IMX/NOPB?

A: The LMC6081IMX/NOPB is supplied in Tape & Reel (TR) format in 8-SOIC surface-mount package configuration (0.154" width, 3.90mm). This format is compatible with automated PCB assembly equipment and standard reflow soldering processes, differing from the die-level packaging of the LMC6081-MDA.
