CA3260AEZ Equivalent & Substitute Parts

Part Overview

The CA3260AEZ is a CMOS amplifier integrated circuit manufactured by Renesas Electronics Corporation, configured as a dual-channel operational amplifier in an 8-DIP package. This device is classified as a linear amplifier and is currently discontinued at DiGi Electronics, with 1906 pieces available as new original stock.

The CA3260AEZ is designed for applications requiring low-power CMOS amplification with dual-circuit configuration. Due to its discontinued status, equivalent substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. Substitute parts must maintain compatibility across package type, pin configuration, circuit count, and electrical operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CA3260AEZ are selected based on strict compatibility criteria across the following key parameters:

Package and Mechanical Compatibility:

• Package type: 8-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Number of circuits: 2 (dual-channel configuration)

Electrical Operating Parameters:

• Voltage supply span: Minimum 4.5 V to maximum 16 V (compatible with CA3260AEZ range of 4 V to 16 V)
• Current supply per channel: Substitute parts operate at 1.9 mA to 2.1 mA per channel, compared to the CA3260AEZ at 9 mA per channel
• Output current per channel: Substitute parts provide 57 mA, compared to CA3260AEZ at 22 mA
• Slew rate: Substitute parts provide 19 V/µs, compared to CA3260AEZ at 10 V/µs
• Gain bandwidth product: Substitute parts provide 10 MHz, compared to CA3260AEZ at 4 MHz

Compliance and Certification:

• RoHS3 Compliant
• REACH Unaffected
• ECCN: EAR99
• HTSUS: 8542.33.0001

All substitute parts listed are general-purpose operational amplifiers from Texas Instruments, classified as TLC072 and TLC082 series devices. These parts maintain the same 8-DIP package configuration and dual-circuit topology, enabling direct pin-compatible substitution in through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Requirements:

The TLC072CP and TLC082CP are recommended for new designs requiring active product status. Both devices are manufactured by Texas Instruments and maintain active production status, ensuring long-term availability and supply chain stability. The TLC082CP provides lower supply current (1.9 mA per channel) compared to TLC072CP (2.1 mA per channel), making it suitable for power-constrained applications. Both operate within the commercial temperature range of 0°C to 70°C.

For Extended Temperature Range Applications:

The TLC072IP, TLC072AIP, TLC082IP, and TLC082AIP are suitable for applications requiring extended operating temperature ranges from -40°C to 125°C. These variants maintain compatibility with the CA3260AEZ temperature specification of -55°C to 125°C within their respective ranges. The TLC082 series (TLC082AIP and TLC082IP) provide lower supply current consumption at 1.9 mA per channel.

For High-Volume Inventory Availability:

The TLC082IP offers the highest inventory availability at 79,100 pieces in stock, providing supply security for large-scale production. This part operates across the extended temperature range of -40°C to 125°C and maintains Last Time Buy status.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and identical ECCN and HTSUS classifications as the original CA3260AEZ, ensuring regulatory compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Can TLC072 and TLC082 series parts be used interchangeably with the CA3260AEZ?

A: Yes, within the constraints of operating temperature range and supply current requirements. Both TLC072 and TLC082 series maintain the same 8-DIP package configuration, dual-circuit topology, and pin compatibility. The primary differences are operating temperature range and supply current consumption. Selection depends on specific application requirements for temperature range and power budget.

Q: What is the difference between TLC072 and TLC082 series?

A: The TLC082 series operates at lower supply current (1.9 mA per channel) compared to TLC072 series (2.1 mA per channel). Both series provide identical slew rate (19 V/µs), gain bandwidth product (10 MHz), and output current per channel (57 mA). The TLC082 series is preferred for power-sensitive applications.

Q: Are there temperature range limitations when substituting the CA3260AEZ?

A: The CA3260AEZ operates from -55°C to 125°C. Substitute parts operate within narrower ranges: TLC072CP and TLC082CP operate from 0°C to 70°C (commercial range), while TLC072IP, TLC072AIP, TLC082IP, and TLC082AIP operate from -40°C to 125°C. Applications requiring operation below -40°C cannot use these substitutes.

Q: What is the significance of the part number suffix (IP, CP, AIP)?

A: The suffix indicates temperature grade and performance binning. IP denotes industrial temperature range (-40°C to 125°C), CP denotes commercial temperature range (0°C to 70°C), and AIP denotes industrial temperature range with tighter input bias current specifications (3 pA for TLC082AIP versus 3 pA standard). Selection depends on application temperature requirements and input bias current specifications.

Q: Can the CA3260AEZ be directly replaced on existing PCBs without modification?

A: Yes. All substitute parts maintain identical 8-DIP package dimensions (0.300", 7.62mm) and through-hole mounting configuration. Direct pin-compatible substitution is possible without PCB modification. However, verify that application supply voltage is at least 4.5 V, as some substitute parts have a minimum supply voltage of 4.5 V compared to the CA3260AEZ minimum of 4 V.

Q: Which substitute part offers the best supply chain availability?

A: The TLC082IP offers the highest inventory availability at 79,100 pieces in stock, providing supply security for large-scale production and long-term availability assurance.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed (TLC072AIP, TLC072CP, TLC072IP, TLC082AIP, TLC082CP, TLC082IP) are ROHS3 compliant and REACH unaffected, matching the compliance status of the original CA3260AEZ.
