OPA693IDG4 Equivalent & Substitute Parts

Part Overview

The OPA693IDG4 is a video buffer amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and production continuity. The OPA693IDG4 serves buffer applications requiring high-speed signal conditioning with 1.4 GHz bandwidth and 2500V/µs slew rate capability. Obsolete status requires engineers to evaluate active or recently obsolete alternatives that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OPA693IDG4 is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) — mandatory for PCB compatibility
• Mounting Type: Surface Mount — required for assembly process compatibility
• Number of Circuits: 1 — functional requirement
• Voltage - Supply compatibility: Must support the required supply voltage range
• Current - Output / Channel: Must meet or exceed 120 mA requirement
• RoHS Status: ROHS3 Compliant — regulatory requirement

Secondary Performance Considerations:

• -3dB Bandwidth and Slew Rate determine signal fidelity in buffer applications
• Current - Supply affects power consumption and thermal design
• Moisture Sensitivity Level (MSL) impacts storage and handling requirements

Substitute parts are grouped into two categories based on performance characteristics:

Category A (Direct Voltage Buffer Replacement): OPA693ID maintains identical electrical specifications and active product status, providing the most direct substitution path.

Category B (Current Feedback Amplifiers with Performance Trade-offs): EL5160ISZ, EL5160ISZ-T7A, and EL5162ISZ-T7A are Renesas Electronics current feedback amplifiers with different bandwidth and slew rate characteristics. These parts share the 8-SOIC package and surface mount compatibility but exhibit different performance profiles requiring application-level verification.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: OPA693ID

The OPA693ID is the preferred substitute for OPA693IDG4 applications. This part maintains identical electrical specifications including 1.4 GHz bandwidth, 2500V/µs slew rate, 120 mA output current, and 13 mA supply current. The OPA693ID carries Active product status, ensuring long-term availability and manufacturing support. Both parts share ROHS3 compliance and identical package specifications (8-SOIC surface mount). The OPA693ID is available in Tube packaging with 2236 units in stock, providing immediate procurement viability. MSL rating of 2 (1 Year) matches the original part, maintaining equivalent handling and storage requirements.

Secondary Alternatives: EL5160ISZ, EL5160ISZ-T7A, EL5162ISZ-T7A

These Renesas Electronics current feedback amplifiers provide substitution paths for applications where performance trade-offs are acceptable. All three parts maintain 8-SOIC surface mount package compatibility and ROHS3 compliance.

EL5160ISZ and EL5160ISZ-T7A exhibit reduced bandwidth (200 MHz) and slew rate (1700V/µs) compared to OPA693IDG4, with significantly lower supply current (750µA and 800µA respectively). EL5160ISZ-T7A provides only 70 mA output current, below the 120 mA requirement. These parts are suitable only for applications where bandwidth and slew rate requirements are less stringent than the original specification.

EL5162ISZ-T7A offers superior slew rate (4000V/µs) and bandwidth (500 MHz) with moderate supply current (1.5mA) and 100 mA output current. This part supports supply voltages up to 12V, matching the original specification range. However, MSL rating of 3 (168 Hours) requires more stringent moisture control during storage and assembly compared to the original part.

All Renesas alternatives carry Obsolete product status, limiting long-term availability assurance.

Frequently Asked Questions (FAQ)

Q: Can OPA693ID be used as a direct replacement for OPA693IDG4?

A: Yes. The OPA693ID is a direct electrical and mechanical equivalent. Both parts share identical -3dB bandwidth (1.4 GHz), slew rate (2500V/µs), supply current (13 mA), output current (120 mA), voltage supply range (5V ~ 12V, ±2.5V ~ 6V), and 8-SOIC package specifications. The primary difference is product status: OPA693ID is Active while OPA693IDG4 is Obsolete. OPA693ID is the recommended substitution path for new designs and production continuity.

Q: What are the key differences between OPA693IDG4 and the Renesas EL5160/EL5162 series?

A: The primary differences are bandwidth, slew rate, and amplifier topology. OPA693IDG4 is a voltage buffer with 1.4 GHz bandwidth and 2500V/µs slew rate. EL5160ISZ and EL5160ISZ-T7A are current feedback amplifiers with 200 MHz bandwidth and 1700V/µs slew rate. EL5162ISZ-T7A is a current feedback amplifier with 500 MHz bandwidth and 4000V/µs slew rate. All three Renesas parts share the 8-SOIC package but exhibit different performance characteristics. Substitution requires verification that reduced bandwidth and slew rate (EL5160 series) or different amplifier topology (all Renesas parts) are compatible with the application.

Q: Are there supply voltage compatibility issues between OPA693IDG4 and substitute parts?

A: OPA693IDG4 supports dual supply operation (±2.5V ~ ±6V) and single supply operation (5V ~ 12V). OPA693ID maintains identical supply specifications. EL5160ISZ and EL5160ISZ-T7A support single supply only (5V ~ 10V), which is narrower than the original part. EL5162ISZ-T7A supports single supply (5V ~ 12V), matching the original single supply range. Applications requiring ±2.5V ~ ±6V dual supply operation cannot use any Renesas substitute without circuit redesign.

Q: What is the impact of different MSL ratings on component handling?

A: OPA693IDG4 and OPA693ID carry MSL 2 (1 Year), allowing one year of storage at controlled humidity before requiring bake-out. EL5160ISZ and EL5160ISZ-T7A carry MSL 1 (Unlimited), requiring no moisture control during storage. EL5162ISZ-T7A carries MSL 3 (168 Hours), requiring bake-out after 168 hours of exposure to ambient humidity. MSL rating affects component shelf life, storage procedures, and assembly process requirements. Higher MSL ratings (3) require more stringent moisture control and may increase manufacturing complexity.

Q: Can EL5160ISZ-T7A be used in applications requiring 120 mA output current?

A: No. EL5160ISZ-T7A provides only 70 mA output current per channel, which is below the OPA693IDG4 specification of 120 mA. Applications requiring 120 mA output current cannot use EL5160ISZ-T7A. EL5160ISZ provides 140 mA output current, exceeding the requirement. EL5162ISZ-T7A provides 100 mA output current, which is below the 120 mA requirement but closer to the original specification.

Q: Is OPA693ID available in the same packaging as OPA693IDG4?

A: Both parts use 8-SOIC (0.154", 3.90mm Width) surface mount packages. OPA693IDG4 packaging is listed as unspecified in the provided data. OPA693ID is available in Tube packaging. Both parts are compatible with identical PCB layouts and assembly processes. The packaging format (Tube vs. unspecified) does not affect electrical or mechanical compatibility.

Q: What is the primary reason OPA693IDG4 requires substitution?

A: OPA693IDG4 carries Obsolete product status, indicating Texas Instruments has discontinued manufacturing and support. Obsolete status creates supply chain risk, potential price volatility, and eventual unavailability. OPA693ID, carrying Active status, provides manufacturing continuity and long-term availability assurance. For new designs and production planning, OPA693ID is the recommended path to ensure sustained component availability.
