OPA2677IRGVR Equivalent & Substitute Parts

Part Overview

The OPA2677IRGVR is a dual-channel current feedback amplifier manufactured by Texas Instruments, housed in a 16-VQFN (4x4) surface mount package with exposed pad. This device is classified as obsolete, indicating discontinued production and limited availability in the market. The OPA2677IRGVR delivers high-speed amplification with a gain bandwidth product of 220 MHz and slew rate of 2000 V/µs, making it suitable for applications requiring fast signal processing and wide bandwidth performance.

Due to its obsolete status, identifying parametrically equivalent substitute parts is essential for design continuity, system maintenance, and procurement planning. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitution of the OPA2677IRGVR is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameter Equivalence:

• Amplifier topology: Current Feedback architecture
• Dual-channel configuration (2 circuits)
• Identical slew rate: 2000 V/µs
• Matching gain bandwidth product: 220 MHz
• Equivalent -3dB bandwidth: 250 MHz
• Input bias current: 10 µA
• Input offset voltage: 800 µV
• Supply current per dual channels: 18 mA
• Output current per channel: 500 mA
• Supply voltage range: 5 V to 12 V
• Operating temperature range: -40°C to 85°C

Mechanical & Packaging Equivalence:

• Package type: 16-VQFN with exposed pad (4x4 mm footprint)
• Surface mount configuration
• Identical pin configuration and PCB layout compatibility

Compliance & Certification Equivalence:

• RoHS3 compliance
• Moisture sensitivity level: 2 (1 Year)
• REACH unaffected status

The OPA2677IRGVT qualifies as a parametric equivalent substitute based on complete alignment with all specified parameters. The primary distinction is packaging format: the substitute is supplied in Tape & Reel (TR) format versus the main part's standard packaging, and product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The OPA2677IRGVT is the direct parametric equivalent substitute for the OPA2677IRGVR. All electrical specifications, mechanical dimensions, pin configurations, and compliance certifications are identical between the two parts.

Primary Advantage of Substitution: The OPA2677IRGVT maintains active product status with Texas Instruments, ensuring continued availability, technical support, and supply chain reliability. The obsolete OPA2677IRGVR presents procurement risk and potential long-term supply constraints.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing and automated assembly processes. This packaging format is compatible with standard pick-and-place equipment and does not affect electrical performance or PCB integration.

Compliance & Certification: Both parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 2, 1 Year). No additional handling, storage, or environmental precautions are required when transitioning from the main part to the substitute.

Direct Replacement Capability: The OPA2677IRGVT functions as a direct drop-in replacement. No circuit modifications, PCB layout changes, or firmware adjustments are necessary. Existing designs utilizing the OPA2677IRGVR can be updated to the OPA2677IRGVT without redesign effort.
