OPA2863DR Equivalent & Substitute Parts

Part Overview

The OPA2863DR is a dual-channel, low-power voltage feedback amplifier manufactured by Texas Instruments, designed for rail-to-rail operation across a 2.7 V to 12.6 V supply range. This device operates at a -3dB bandwidth of 110 MHz with a slew rate of 105 V/µs, making it suitable for high-speed signal conditioning and amplification applications. The OPA2863DR is classified as an Active product with full RoHS3 compliance and REACH unaffected status. Identification of equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and maintain performance specifications across multiple sourcing channels.

Substitute Part Grouping Explanation

Substitution of the OPA2863DR is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute relationship is established when a candidate part maintains identical specifications in the following key areas:

Electrical Performance Criteria:

• Amplifier topology (Voltage Feedback)
• Number of circuits (2 channels)
• Output configuration (Rail-to-Rail)
• Bandwidth performance (-3dB Bandwidth: 110 MHz)
• Gain Bandwidth Product (50 MHz)
• Slew rate (105 V/µs)
• Supply voltage range (2.7 V to 12.6 V)
• Input bias current (300 nA)
• Input offset voltage (400 µV)
• Supply current per channel (700 µA x2)
• Output current capability (45 mA per channel)
• Operating temperature range (-40°C to 125°C)

Mechanical & Compliance Criteria:

• Package type (8-SOIC surface mount)
• Physical dimensions (0.154" width, 3.90mm)
• RoHS3 compliance status
• Moisture Sensitivity Level (MSL 1)
• REACH compliance status
• Product status (Active)

Only parts meeting all specified parameters across both electrical and mechanical categories qualify as direct substitutes for the OPA2863DR.

Engineering Selection Recommendations

The OPA2863DR maintains Active product status with full regulatory compliance across RoHS3 and REACH frameworks. Selection of equivalent parts for the OPA2863DR should prioritize components with identical Active status to ensure long-term availability and manufacturing support. All substitute candidates must maintain RoHS3 compliance and REACH unaffected designation to satisfy environmental and regulatory requirements in industrial and commercial applications.

The 8-SOIC surface mount package with MSL 1 rating provides unlimited moisture sensitivity tolerance, eliminating moisture-related handling constraints during assembly and storage. This characteristic is critical for high-volume manufacturing environments and extended supply chain operations.

Electrical parameter equivalence across bandwidth, slew rate, supply current, and output current specifications ensures direct functional replacement without circuit redesign or performance degradation. The dual-channel configuration with rail-to-rail output capability supports applications requiring symmetric signal conditioning across multiple signal paths within a single integrated circuit.

Frequently Asked Questions (FAQ)

Q: What defines a direct substitute for the OPA2863DR?

A: A direct substitute must match all electrical parameters (bandwidth, slew rate, supply voltage range, input bias current, input offset voltage, supply current, and output current) and all mechanical parameters (8-SOIC package, surface mount configuration, physical dimensions). The part must also maintain identical RoHS3 compliance, MSL 1 rating, and Active product status.

Q: Can the OPA2863DR be replaced with a single-channel amplifier variant?

A: No. The OPA2863DR is a dual-channel device with 2 circuits. Substitutes must maintain the 2-circuit configuration. Single-channel alternatives do not qualify as direct substitutes.

Q: Are there packaging alternatives for the OPA2863DR?

A: The OPA2863DR is specified in 8-SOIC surface mount package only. Substitutes must use the identical 8-SOIC package with 0.154" width and 3.90mm dimensions. Alternative package types do not qualify as direct substitutes.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited moisture tolerance. The component does not require special moisture control during storage, handling, or assembly. This simplifies supply chain management and reduces storage costs.

Q: Does the OPA2863DR support both positive and negative supply voltages?

A: The OPA2863DR operates across a 2.7 V to 12.6 V supply span. This specification covers single-supply operation. Dual-supply configurations (positive and negative rails) are not within the specified operating parameters.

Q: What is the relationship between Gain Bandwidth Product and -3dB Bandwidth?

A: The OPA2863DR specifies a Gain Bandwidth Product of 50 MHz and a -3dB Bandwidth of 110 MHz. These are independent specifications reflecting different measurement conditions. Both values must be matched in substitute parts.

Q: Is the OPA2863DR suitable for low-power applications?

A: Yes. The OPA2863DR is classified as a low-power device with 700 µA supply current per channel and 300 nA input bias current, making it suitable for battery-powered and energy-constrained applications.

Q: What compliance certifications apply to the OPA2863DR?

A: The OPA2863DR is RoHS3 compliant and REACH unaffected. These certifications confirm compliance with European environmental and chemical safety regulations.
