LMC6024IM Equivalent & Substitute Parts

Part Overview

The LMC6024IM is a CMOS 4-circuit operational amplifier manufactured by Texas Instruments, housed in a 14-SOIC surface mount package. This device features rail-to-rail output capability and is designed for low-power analog signal processing applications. The LMC6024IM is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility across key electrical parameters including supply voltage range, circuit count, output type, and package configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LMC6024IM are selected based on strict electrical and mechanical compatibility criteria. The following parameters define acceptable substitution:

Primary Compatibility Criteria:

• Number of Circuits: 4 (quad configuration required)
• Output Type: Rail-to-Rail (mandatory for signal swing requirements)
• Package / Case: 14-SOIC surface mount (identical footprint and pinout)
• Voltage - Supply Span: Minimum 5 V, Maximum 16 V (encompasses original 4.75 V to 15.5 V range)
• Mounting Type: Surface Mount (identical assembly process)

Secondary Compatibility Criteria:

• Operating Temperature Range: -40°C minimum, 85°C minimum (original specification met or exceeded)
• Moisture Sensitivity Level: 1 (Unlimited) (no additional handling requirements)
• ECCN and HTSUS classifications: Identical (regulatory equivalence)

The AD8668ARZ, AD8668ARZ-REEL, and AD8668ARZ-REEL7 satisfy all primary and secondary criteria. These parts are manufactured by Analog Devices Inc. and maintain identical pinout and package dimensions. Differences in packaging format (Tube versus Tape & Reel) do not affect electrical compatibility or circuit performance.

Engineering Selection Recommendations

Product Status Consideration: The LMC6024IM is classified as obsolete. The AD8668ARZ, AD8668ARZ-REEL, and AD8668ARZ-REEL7 are all active products, ensuring long-term availability and continued manufacturing support.

Compliance and Certification: The AD8668 series components are ROHS3 compliant, whereas the LMC6024IM is non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the AD8668 series provides regulatory alignment. Both the original and substitute parts maintain identical REACH Unaffected and EAR99 ECCN classifications.

Packaging Format Selection: Three AD8668 variants are available:

• AD8668ARZ (Tube): Standard packaging for lower-volume applications
• AD8668ARZ-REEL (Tape & Reel): Standard reel format for automated assembly
• AD8668ARZ-REEL7 (Tape & Reel): Extended reel format with higher unit count per reel

Selection between packaging formats depends on production volume and assembly line requirements. Electrical performance is identical across all three variants.

Performance Envelope: The AD8668 series demonstrates superior performance characteristics compared to the LMC6024IM across multiple parameters: slew rate (3.5 V/µs versus 0.11 V/µs), gain bandwidth product (4 MHz versus 350 kHz), and output current capability (140 mA versus 40 mA per channel). These enhancements provide design margin for signal processing applications. The extended operating temperature range (-40°C to 125°C versus -40°C to 85°C) accommodates wider environmental specifications.

Frequently Asked Questions (FAQ)

Q: Can the AD8668ARZ directly replace the LMC6024IM without circuit modifications?

A: Yes. The AD8668ARZ maintains identical pinout, package footprint (14-SOIC), and supply voltage compatibility (5 V to 16 V operating range encompasses the LMC6024IM specification of 4.75 V to 15.5 V). No PCB layout changes or schematic modifications are required for direct substitution.

Q: What is the difference between AD8668ARZ, AD8668ARZ-REEL, and AD8668ARZ-REEL7?

A: These three part numbers represent identical electrical devices with different packaging formats. AD8668ARZ is supplied in Tube packaging. AD8668ARZ-REEL and AD8668ARZ-REEL7 are both supplied in Tape & Reel format, with REEL7 indicating a larger reel configuration. Selection depends on production volume and assembly equipment compatibility. Electrical performance and pinout are identical.

Q: Are there any performance differences between the LMC6024IM and AD8668ARZ?

A: The AD8668ARZ provides enhanced performance specifications. Slew rate is 3.5 V/µs compared to 0.11 V/µs, gain bandwidth product is 4 MHz compared to 350 kHz, and output current per channel is 140 mA compared to 40 mA. These improvements represent design enhancements and do not create compatibility issues. Applications designed for the LMC6024IM will function correctly with the AD8668ARZ.

Q: Is the AD8668ARZ suitable for applications requiring RoHS compliance?

A: Yes. The AD8668ARZ is ROHS3 compliant, whereas the LMC6024IM is non-compliant. For new designs or production requiring RoHS certification, the AD8668ARZ satisfies regulatory requirements.

Q: What is the operating temperature range difference, and does it affect substitution?

A: The LMC6024IM operates from -40°C to 85°C, while the AD8668ARZ operates from -40°C to 125°C. The AD8668ARZ provides an extended upper temperature limit. For applications operating within the original -40°C to 85°C range, both devices are functionally equivalent. For applications requiring operation above 85°C, the AD8668ARZ provides additional thermal margin.

Q: Are moisture sensitivity levels identical between the LMC6024IM and AD8668ARZ?

A: Yes. Both devices are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control or baking requirements during storage or assembly.

Q: Can the AD8668ARZ be used in high-volume production with automated assembly?

A: Yes. The AD8668ARZ-REEL and AD8668ARZ-REEL7 variants are specifically formatted for automated tape-and-reel assembly processes. AD8668ARZ-REEL7 is recommended for high-volume production due to extended reel capacity, reducing feeder changeover frequency.
