CA3102MZ Equivalent & Substitute Parts

Part Overview

The CA3102MZ is a differential amplifier integrated circuit manufactured by Renesas Electronics Corporation, configured as a 2-circuit differential amplifier in a 14-SOIC surface mount package. This device is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The CA3102MZ operates across an industrial temperature range of -55°C to 125°C and delivers a gain bandwidth product of 1.35 GHz with an input bias current of 13.5 µA and input offset voltage of 250 µV.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CA3102MZ is determined by strict alignment of the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 14-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm Width) to ensure direct PCB footprint compatibility without layout modifications.

Functional Configuration: The substitute must provide 2 differential amplifier circuits to match the CA3102MZ configuration and maintain circuit functionality.

Electrical Performance: The substitute must operate as a differential amplifier with compatible input and output characteristics. The AD8279BRZ meets these requirements as a 2-circuit differential amplifier in the identical 14-SOIC package.

Compliance and Certification: Both parts must maintain ROHS3 compliance and REACH unaffected status to satisfy regulatory requirements for equivalent component selection.

The AD8279BRZ qualifies as a direct substitute based on matching package type, circuit count, amplifier topology, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The AD8279BRZ is an active product from Analog Devices Inc. and serves as the primary substitute for the obsolete CA3102MZ. Both components maintain identical package specifications (14-SOIC) and circuit configuration (2 differential amplifiers), ensuring direct PCB compatibility without design modifications.

Both parts satisfy ROHS3 compliance and REACH unaffected regulatory status. The AD8279BRZ offers improved moisture sensitivity characteristics (MSL 1 versus MSL 3) and lower input offset voltage (50 µV versus 250 µV), providing enhanced performance stability in production environments.

The operating temperature range differs between the two parts: the CA3102MZ operates from -55°C to 125°C, while the AD8279BRZ operates from -40°C to 85°C. Applications requiring extended low-temperature operation below -40°C or high-temperature operation above 85°C must evaluate this specification difference against system requirements.

The AD8279BRZ is currently in active production with established supply chain availability, eliminating obsolescence risk associated with the CA3102MZ.

Frequently Asked Questions (FAQ)

Q: Can the AD8279BRZ be used as a direct replacement for the CA3102MZ without PCB modifications?

A: Yes. Both components use the identical 14-SOIC surface mount package with matching physical dimensions (0.154", 3.90mm Width). The footprint and pin configuration are compatible, allowing direct substitution without PCB layout changes.

Q: What are the key differences between the CA3102MZ and AD8279BRZ?

A: The primary differences are product status (CA3102MZ is obsolete; AD8279BRZ is active), operating temperature range (CA3102MZ: -55°C to 125°C; AD8279BRZ: -40°C to 85°C), input offset voltage (CA3102MZ: 250 µV; AD8279BRZ: 50 µV), and moisture sensitivity level (CA3102MZ: MSL 3; AD8279BRZ: MSL 1).

Q: Are both parts RoHS compliant?

A: Yes. Both the CA3102MZ and AD8279BRZ are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the significance of the different moisture sensitivity levels?

A: The CA3102MZ has MSL 3 (168 hours), requiring controlled storage and handling conditions. The AD8279BRZ has MSL 1 (unlimited), indicating superior moisture resistance and reduced handling restrictions during manufacturing and storage.

Q: Does the lower input offset voltage of the AD8279BRZ affect circuit performance?

A: The AD8279BRZ input offset voltage of 50 µV is lower than the CA3102MZ specification of 250 µV. This represents improved precision and reduced DC error in differential amplification applications. Existing designs using the CA3102MZ will function with the AD8279BRZ without circuit modifications.

Q: Are there temperature range limitations when substituting the AD8279BRZ?

A: The AD8279BRZ operates from -40°C to 85°C, compared to the CA3102MZ range of -55°C to 125°C. Applications requiring operation below -40°C or above 85°C must confirm that the AD8279BRZ temperature range meets system specifications before substitution.

Q: What is the packaging format for the AD8279BRZ?

A: The AD8279BRZ is supplied in tube packaging, while the CA3102MZ packaging format is not specified in the available data. Both components use the 14-SOIC package type for the integrated circuit itself.
