OPA693IDR Equivalent & Substitute Parts

Part Overview

The OPA693IDR is a video buffer amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device is classified as obsolete, indicating discontinued production and limited availability for new designs. The OPA693IDR serves buffer applications requiring high-speed signal conditioning with a -3dB bandwidth of 1.4 GHz and slew rate of 2500V/µs. Due to its obsolete status, identifying functionally compatible substitute components is essential for design continuity, production support, and long-term supply chain management.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OPA693IDR is determined by strict alignment of the following critical parameters:

Package Compatibility: The substitute must use the 8-SOIC (0.154", 3.90mm Width) surface mount package to ensure PCB layout compatibility without redesign.

Electrical Performance Envelope: The substitute must operate within the supply voltage range of 5V ~ 12V and ±2.5V ~ 6V to maintain circuit functionality in existing designs.

Output Current Capability: The substitute must deliver a minimum of 100 mA output current per channel to support load requirements.

Supply Current: The substitute must operate with supply current not exceeding 13 mA to maintain power budget compliance.

Environmental & Compliance Standards: The substitute must maintain ROHS3 compliance and REACH unaffected status to satisfy regulatory requirements for the application.

The EL5162ISZ-T7A, manufactured by Renesas Electronics Corporation, meets these substitution criteria. While the EL5162ISZ-T7A exhibits different amplifier architecture (current feedback versus voltage feedback) and higher bandwidth performance (500 MHz versus 1.4 GHz), it satisfies all mandatory package, electrical, and compliance parameters required for direct substitution in buffer applications.

Parameter Comparison

Engineering Selection Recommendations

Both the OPA693IDR and EL5162ISZ-T7A are classified as obsolete products. Selection between these components should be based on inventory availability and application-specific requirements rather than performance preference.

The OPA693IDR offers higher bandwidth (1.4 GHz) and lower slew rate (2500V/µs), suitable for applications requiring extended frequency response. The EL5162ISZ-T7A provides superior slew rate performance (4000V/µs) and reduced supply current consumption (1.5 mA), beneficial for power-constrained designs.

Both devices maintain identical package geometry (8-SOIC), supply voltage compatibility (5V ~ 12V), and regulatory compliance (ROHS3, REACH unaffected). The EL5162ISZ-T7A output current specification (100 mA) is marginally lower than the OPA693IDR (120 mA), requiring verification against specific load impedance requirements.

For new designs or long-term production support, evaluation of current-generation buffer amplifiers in equivalent packages is recommended to ensure sustained component availability beyond the obsolete status of both alternatives.

Frequently Asked Questions (FAQ)

Q: Can the EL5162ISZ-T7A directly replace the OPA693IDR without PCB modification?

A: Yes. Both devices use identical 8-SOIC (0.154", 3.90mm Width) surface mount packages with compatible pinout configurations for buffer applications. PCB layout remains unchanged.

Q: What is the primary difference between the OPA693IDR and EL5162ISZ-T7A?

A: The OPA693IDR is a voltage feedback amplifier with 1.4 GHz bandwidth, while the EL5162ISZ-T7A is a current feedback amplifier with 500 MHz bandwidth. The EL5162ISZ-T7A exhibits higher slew rate (4000V/µs) and lower supply current (1.5 mA).

Q: Are both devices compliant with current environmental regulations?

A: Yes. Both the OPA693IDR and EL5162ISZ-T7A are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the output current limitation when substituting with the EL5162ISZ-T7A?

A: The EL5162ISZ-T7A provides 100 mA output current per channel, compared to 120 mA for the OPA693IDR. Applications requiring output current exceeding 100 mA require circuit redesign or alternative component selection.

Q: Why are both devices classified as obsolete?

A: Obsolete status indicates discontinued production by the manufacturer. Both components remain available through authorized distributors with existing inventory, but long-term availability is not guaranteed.

Q: What supply voltage configurations are supported by the EL5162ISZ-T7A?

A: The EL5162ISZ-T7A operates with single supply voltage from 5V to 12V. Dual supply operation (±2.5V to ±6V) requires verification against device datasheet specifications.
