OPA693IDBVR Equivalent & Substitute Parts

Part Overview

The OPA693IDBVR is a video buffer amplifier manufactured by Texas Instruments, classified as a linear integrated circuit in the amplifier category. This single-circuit buffer device is packaged in SOT-23-6 surface mount configuration and operates across supply voltage ranges of 5V to 12V (single supply) or ±2.5V to 6V (dual supply). The OPA693IDBVR maintains active product status with RoHS3 compliance and is suitable for video amplification and buffering applications requiring high-speed signal conditioning.

Substitute parts become necessary when addressing supply chain constraints, inventory availability, or specific application requirements that benefit from alternative amplifier topologies or performance characteristics within compatible package and electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the OPA693IDBVR is determined by the following critical parameters:

Package Compatibility: All substitute parts must use SOT-23-6 surface mount packaging to ensure mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Supply Voltage Range: Substitute amplifiers must operate within the 5V to 12V single supply range or equivalent dual supply specifications to function in the target application circuit.

Number of Circuits: Single-circuit configuration is required to maintain functional equivalence.

Bandwidth and Slew Rate: While the OPA693IDBVR operates at 1.4 GHz bandwidth with 2500 V/µs slew rate, substitute parts may exhibit different performance characteristics. Substitutes with equal or superior bandwidth and slew rate specifications maintain or exceed the original performance envelope.

Output Current Capability: Substitute parts must deliver minimum 100 mA output current per channel to support typical buffering and driving applications.

Compliance Requirements: All substitute parts must maintain RoHS3 compliance and MSL 2 moisture sensitivity rating to satisfy regulatory and manufacturing requirements.

The three qualified substitute parts—EL5106IWZ-T7A, EL5164IWZ-T7, and EL5164IWZ-T7A—satisfy these substitution criteria despite differences in amplifier topology (general purpose versus current feedback) and performance metrics.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: OPA693IDBVR

The OPA693IDBVR remains the preferred component choice due to its active product status, ensuring long-term availability and manufacturing support. This Texas Instruments device delivers the highest bandwidth specification (1.4 GHz) among all listed options and maintains full RoHS3 compliance with standard MSL 2 moisture sensitivity rating.

Secondary Selection: EL5164IWZ-T7 or EL5164IWZ-T7A

The Renesas EL5164 series (both T7 and T7A variants) provides current feedback amplifier topology with 600 MHz bandwidth and 4700 V/µs slew rate. These devices exceed the OPA693IDBVR slew rate specification and deliver superior output current capability (190 mA). However, both variants carry obsolete product status, indicating discontinued manufacturing and potential long-term supply constraints. The EL5164IWZ-T7A variant is preferred over EL5164IWZ-T7 when available, as it represents the latest revision. Both maintain full RoHS3 compliance and MSL 2 rating.

Tertiary Selection: EL5106IWZ-T7A

The Renesas EL5106IWZ-T7A general purpose amplifier operates at 380 MHz bandwidth with 4500 V/µs slew rate and delivers 100 mA output current. This device exhibits the lowest supply current consumption (1.5 mA) among substitutes and maintains RoHS3 compliance. The obsolete product status and significantly reduced bandwidth (380 MHz versus 1.4 GHz) limit its application to lower-frequency buffering scenarios. Selection of this part requires verification that application bandwidth requirements do not exceed 380 MHz.

Compliance Verification

All listed parts satisfy RoHS3 compliance and MSL 2 moisture sensitivity requirements. No additional regulatory or environmental certifications are specified in the provided parameters.

Frequently Asked Questions (FAQ)

Q: Can the EL5164IWZ-T7A directly replace the OPA693IDBVR in existing designs?

A: Direct replacement is mechanically and electrically feasible. Both devices use SOT-23-6 packaging, operate across 5V to 12V supply range, and deliver single-circuit amplification. However, the EL5164IWZ-T7A exhibits 600 MHz bandwidth compared to the OPA693IDBVR's 1.4 GHz specification. Applications requiring bandwidth above 600 MHz will not function correctly with this substitute. The EL5164IWZ-T7A is obsolete, creating potential long-term supply risk.

Q: What is the primary difference between EL5164IWZ-T7 and EL5164IWZ-T7A?

A: Both variants are current feedback amplifiers with identical electrical specifications: 600 MHz bandwidth, 4700 V/µs slew rate, and 5V to 12V supply range. The T7A designation indicates a later revision. Both are obsolete. The EL5164IWZ-T7A is preferred when available due to its more recent manufacturing revision.

Q: Why does the EL5106IWZ-T7A have lower supply current than the OPA693IDBVR?

A: The EL5106IWZ-T7A is a general purpose amplifier topology with 380 MHz bandwidth, compared to the OPA693IDBVR video buffer at 1.4 GHz. Lower bandwidth operation typically correlates with reduced quiescent current consumption. The 1.5 mA supply current of the EL5106IWZ-T7A reflects its lower-frequency design intent.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The OPA693IDBVR, EL5106IWZ-T7A, EL5164IWZ-T7, and EL5164IWZ-T7A all carry ROHS3 Compliant status. All parts maintain MSL 2 (1 Year) moisture sensitivity level, satisfying standard manufacturing and environmental requirements.

Q: What is the impact of obsolete product status on the EL5164 and EL5106 substitutes?

A: Obsolete status indicates discontinued manufacturing by the original supplier. While current inventory exists (EL5164IWZ-T7: 2956 units; EL5164IWZ-T7A: 1069 units; EL5106IWZ-T7A: 4122 units), no future production is guaranteed. Long-term designs should prioritize the active OPA693IDBVR to ensure sustained component availability.

Q: Can the EL5106IWZ-T7A substitute for the OPA693IDBVR in video buffering applications?

A: The EL5106IWZ-T7A is a general purpose amplifier with 380 MHz bandwidth. Video buffering applications typically require minimum 1 GHz bandwidth for standard video signal conditioning. The EL5106IWZ-T7A is unsuitable for video applications requiring the OPA693IDBVR's 1.4 GHz bandwidth specification.

Q: What output current capability should be verified when selecting a substitute?

A: The OPA693IDBVR delivers 120 mA output current per channel. The EL5164 series provides 190 mA (exceeding the original), while the EL5106IWZ-T7A delivers 100 mA (slightly below the original). Applications requiring output current above 100 mA should verify that the selected substitute meets the specific load-driving requirement.
