OPA820IDBVR Equivalent & Substitute Parts

Part Overview

The OPA820IDBVR is a voltage feedback operational amplifier manufactured by Texas Instruments, housed in a SOT-23-5 surface mount package. This single-circuit op-amp is designed for high-speed signal conditioning applications requiring moderate bandwidth and slew rate performance. The device is currently in active production status with 22,300 units available in inventory. Substitute parts are identified when equivalent electrical performance, package compatibility, and supply voltage specifications align with the original component's operational requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OPA820IDBVR are classified into two categories based on substitution type:

MFR Recommended Substitutes: Parts that exceed or match the electrical performance specifications of the original component while maintaining package and mounting compatibility. These substitutes are approved by the manufacturer for direct replacement in applications where enhanced performance characteristics are acceptable.

Parametric Equivalents: Parts that maintain identical electrical specifications and package form factor, differing only in packaging configuration (Cut Tape versus Tape & Reel).

Substitution eligibility is determined by the following critical parameters:

• Amplifier Type (Voltage Feedback architecture)
• Number of Circuits (single circuit configuration)
• Package / Case (SC-74A, SOT-753)
• Mounting Type (Surface Mount)
• Supply Voltage Range (minimum 5V, maximum 12V compatibility)
• Operating Temperature Range (minimum -40°C capability)

Parameter Comparison

Engineering Selection Recommendations

OPA820IDBVT (Parametric Equivalent): This part is electrically identical to the OPA820IDBVR, with all specifications matching exactly. The sole difference is packaging configuration: OPA820IDBVT is supplied in Tape & Reel (TR) format, while OPA820IDBVR is supplied in Cut Tape (CT) & Digi-Reel® format. Selection between these two depends on procurement volume and assembly line requirements. Both maintain ROHS3 compliance and identical moisture sensitivity specifications.

LMH6624MF/NOPB (MFR Recommended Substitute): This substitute provides enhanced performance across multiple parameters. Slew rate increases from 240 V/µs to 400 V/µs, and gain bandwidth product increases from 280 MHz to 1500 MHz. Input offset voltage improves from 200 µV to 100 µV. Operating temperature range extends to -40°C to 125°C. Moisture sensitivity improves to Level 1 (Unlimited). Supply current increases to 12 mA. This substitute is suitable for applications requiring higher bandwidth and improved temperature performance. ROHS3 compliance is maintained.

LMH6657MF/NOPB (MFR Recommended Substitute): This substitute offers the highest slew rate at 700 V/µs and lowest input bias current at 5 µA. However, gain bandwidth product decreases to 140 MHz and -3dB bandwidth reduces to 270 MHz. Input offset voltage increases to 1 mV. Supply voltage minimum extends to 3 V, enabling single-supply operation at lower voltages. Supply current is 6.5 mA. This substitute is appropriate for applications prioritizing slew rate performance and lower supply voltage operation. RoHS and moisture sensitivity status are not specified for this part.

All substitute parts maintain the SOT-23-5 package configuration and surface mount mounting type, ensuring mechanical and electrical compatibility with the original design footprint.

Frequently Asked Questions (FAQ)

Q: Can OPA820IDBVT be used as a direct replacement for OPA820IDBVR?

A: Yes. OPA820IDBVT is a parametric equivalent with identical electrical specifications. The only difference is packaging format: OPA820IDBVT uses Tape & Reel (TR) packaging while OPA820IDBVR uses Cut Tape (CT) & Digi-Reel® packaging. Both parts are suitable for the same circuit applications.

Q: What are the key differences between LMH6624MF/NOPB and the original OPA820IDBVR?

A: LMH6624MF/NOPB provides higher performance in slew rate (400 V/µs vs. 240 V/µs), gain bandwidth product (1500 MHz vs. 280 MHz), and input offset voltage (100 µV vs. 200 µV). Operating temperature range extends to 125°C. Supply current increases to 12 mA. Moisture sensitivity improves to Level 1. These enhancements make it suitable for higher-speed applications and extended temperature environments.

Q: Is LMH6657MF/NOPB compatible with the OPA820IDBVR footprint?

A: Yes. LMH6657MF/NOPB uses the same SC-74A, SOT-753 package and surface mount configuration. However, verify that your application can accommodate the different electrical characteristics, particularly the lower gain bandwidth product (140 MHz vs. 280 MHz) and higher input offset voltage (1 mV vs. 200 µV).

Q: Can I use LMH6657MF/NOPB in a 5V supply application?

A: LMH6657MF/NOPB has a minimum supply voltage of 3V, so it operates at 5V. However, verify that your circuit design does not depend on the supply voltage characteristics of the original OPA820IDBVR, which has a 5V minimum specification.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging provides individual components cut from the reel, suitable for small-volume or manual assembly. Tape & Reel (TR) packaging maintains components on the reel for automated pick-and-place assembly equipment. Both formats contain identical components; packaging selection depends on assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: OPA820IDBVR, OPA820IDBVT, and LMH6624MF/NOPB are confirmed ROHS3 compliant. RoHS compliance status for LMH6657MF/NOPB is not specified in the provided data.

Q: Which substitute offers the best performance for high-speed applications?

A: LMH6624MF/NOPB provides the highest gain bandwidth product at 1500 MHz, making it the best choice for high-speed signal conditioning. LMH6657MF/NOPB offers the highest slew rate at 700 V/µs, suitable for applications requiring fast transient response.

Q: What is the moisture sensitivity implication for long-term storage?

A: OPA820IDBVR and OPA820IDBVT have MSL Level 2 with 1-year shelf life, requiring controlled storage conditions. LMH6624MF/NOPB has MSL Level 1 with unlimited shelf life, providing greater flexibility for inventory management.
