VCA810IDRG4 Equivalent & Substitute Parts

Part Overview

The VCA810IDRG4 is a variable gain amplifier integrated circuit manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device is designed for applications requiring adjustable gain control with high bandwidth performance. The VCA810IDRG4 is currently discontinued at DiGi Electronics, necessitating identification of equivalent substitute components for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VCA810IDRG4 is determined by the following critical parameters:

Primary Substitution Criteria:

• Package compatibility: 8-SOIC surface mount form factor
• Amplifier classification: Variable gain topology
• Bandwidth performance: 35 MHz minimum
• Supply voltage range: 8 V to 12 V operation
• Output current capability: 60 mA per channel minimum
• Regulatory compliance: ROHS3 and REACH requirements

Substitute Classification:

Direct Equivalent (Manufacturer Recommended): VCA810IDR is the active production equivalent of the discontinued VCA810IDRG4. Both devices share identical electrical specifications, package configuration, and functional characteristics. The VCA810IDR differs only in product status (active vs. discontinued) and inventory availability.

Functional Alternative (Limited Compatibility): MAX410CSA+T is a general purpose amplifier that shares the 8-SOIC package footprint and surface mount mounting type. However, this device operates as a general purpose amplifier rather than a variable gain amplifier, resulting in significant electrical parameter differences that restrict its application scope.

Engineering Selection Recommendations

Primary Selection: VCA810IDR

The VCA810IDR is the manufacturer-recommended substitute for the discontinued VCA810IDRG4. Both devices are produced by Texas Instruments and maintain identical electrical specifications across all measured parameters. The VCA810IDR carries active product status with significantly higher inventory availability (4789 units vs. 721 units). Both devices meet ROHS3 compliance and REACH requirements. The VCA810IDR is suitable for direct replacement in all applications originally designed for the VCA810IDRG4 without circuit modification or performance degradation.

Secondary Selection: MAX410CSA+T

The MAX410CSA+T is an alternative only for applications where variable gain functionality is not required. This device is manufactured by Analog Devices Inc./Maxim Integrated and operates as a general purpose amplifier. Significant electrical parameter differences exist: slew rate is reduced to 4.5 V/µs (versus 350 V/µs), output current capability is limited to 35 mA (versus 60 mA), and input bias current is substantially lower at 80 nA. The operating temperature range is narrower (0°C to 70°C versus -40°C to 85°C). The MAX410CSA+T is packaged in Tape & Reel format with superior moisture sensitivity rating (MSL 1 vs. MSL 2). Selection of the MAX410CSA+T requires circuit redesign and is appropriate only when variable gain control is not a functional requirement.

Frequently Asked Questions (FAQ)

Q: Can the VCA810IDR be used as a direct replacement for the VCA810IDRG4?

A: Yes. The VCA810IDR is the active production equivalent of the VCA810IDRG4. Both devices share identical electrical specifications, package configuration, and functional characteristics. No circuit modification is required.

Q: What is the primary difference between the VCA810IDRG4 and VCA810IDR?

A: The VCA810IDRG4 is discontinued at DiGi Electronics, while the VCA810IDR maintains active product status. Electrical performance and package specifications are identical.

Q: Is the MAX410CSA+T a suitable replacement for the VCA810IDRG4?

A: The MAX410CSA+T shares the 8-SOIC package footprint but is not a functional equivalent. The MAX410CSA+T is a general purpose amplifier, not a variable gain amplifier. Significant electrical parameter differences exist, including slew rate (4.5 V/µs vs. 350 V/µs), output current (35 mA vs. 60 mA), and operating temperature range (0°C to 70°C vs. -40°C to 85°C). Selection of the MAX410CSA+T requires circuit redesign and is appropriate only when variable gain control is not required.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The VCA810IDR and MAX410CSA+T are both ROHS3 compliant and REACH unaffected, matching the compliance status of the VCA810IDRG4.

Q: What is the difference in moisture sensitivity between the substitute parts?

A: The VCA810IDR maintains the same moisture sensitivity level as the VCA810IDRG4 (MSL 2, 1 Year). The MAX410CSA+T has superior moisture sensitivity (MSL 1, Unlimited), indicating lower moisture absorption risk during storage and handling.

Q: Can the VCA810IDR operate in the same temperature range as the VCA810IDRG4?

A: Yes. Both devices operate across the identical temperature range of -40°C to 85°C.

Q: What is the package configuration for all listed parts?

A: All three devices (VCA810IDRG4, VCA810IDR, and MAX410CSA+T) are housed in 8-SOIC surface mount packages with 0.154" (3.90mm) width. PCB footprints are identical.
