EL5102IS Equivalent & Substitute Parts

Part Overview

The EL5102IS is a voltage feedback amplifier manufactured by Renesas Electronics Corporation, housed in an 8-SOIC surface mount package. This device is classified as obsolete, necessitating identification of active equivalent components for new designs and production continuity. The EL5102IS delivers a slew rate of 4000V/µs with a -3dB bandwidth of 400 MHz, operating across a supply voltage range of 3V to 13.2V. Due to its obsolete status, equivalent substitutes from active product lines are required for ongoing applications.

Substitute Part Grouping Explanation

Substitution of the EL5102IS is determined by the following critical parameters: amplifier type (voltage feedback), single circuit configuration, package format (8-SOIC surface mount), operating temperature range (-40°C to 85°C), and supply voltage compatibility. All substitute parts listed maintain these core electrical and mechanical characteristics.

The substitute parts are grouped into two categories based on performance alignment:

Category A - High Slew Rate Performance: OPA690ID delivers slew rate and bandwidth characteristics closest to the EL5102IS, with 1800V/µs slew rate and 500 MHz bandwidth, supporting applications requiring rapid signal transitions.

Category B - Moderate Slew Rate Performance: OPA820ID, OPA820IDG4, OPA820IDR, and AD8037ARZ-REEL7 operate at reduced slew rates (240V/µs to 1500V/µs) but maintain the 8-SOIC package format and single-circuit configuration. These parts are suitable for applications where the original slew rate specification is not a limiting constraint.

All substitute parts operate within the -40°C to 85°C temperature range and maintain 8-SOIC surface mount packaging, ensuring mechanical and thermal compatibility.

Engineering Selection Recommendations

For Active Product Line Continuity: OPA820IDR is the recommended primary substitute. This part is actively manufactured by Texas Instruments, maintains ROHS3 compliance, and is available in high inventory (6062 units). The OPA820IDR operates within the same 8-SOIC package and temperature range as the EL5102IS. While the slew rate is reduced to 240V/µs compared to the original 4000V/µs, the -3dB bandwidth of 800 MHz exceeds the original specification. This part is suitable for applications where the original slew rate is not a critical design constraint.

For High-Speed Applications: OPA690ID from Texas Instruments provides the closest performance match to the EL5102IS in terms of slew rate (1800V/µs) and bandwidth (500 MHz). This part is actively produced, ROHS3 compliant, and available in substantial inventory (1865 units). The OPA690ID is appropriate for designs requiring rapid signal transitions and high-frequency operation.

For Compliance-Critical Applications: AD8037ARZ-REEL7 from Analog Devices Inc. is ROHS3 compliant and actively produced. This part operates at 1500V/µs slew rate and is supplied in Tape & Reel packaging. The higher supply current (18.5mA) and lower output current capability (70mA) require circuit evaluation before selection.

Parts to Avoid: OPA820IDG4 is discontinued at DiGi Electronics and should not be selected for new designs requiring long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can the EL5102IS be directly replaced with any of these substitute parts?

A: Direct replacement is possible from a package and pinout perspective, as all substitutes use the 8-SOIC surface mount package. However, circuit performance must be evaluated based on slew rate, bandwidth, and output current requirements specific to the application. The OPA820IDR and OPA690ID are the most straightforward replacements for general voltage feedback amplifier applications.

Q: What is the primary difference between OPA690ID and OPA820IDR?

A: The OPA690ID provides higher slew rate (1800V/µs versus 240V/µs) and higher bandwidth (500 MHz versus 800 MHz -3dB bandwidth). The OPA820IDR offers lower slew rate but higher -3dB bandwidth. Selection depends on whether the application prioritizes slew rate performance or bandwidth characteristics.

Q: Are all substitute parts RoHS compliant?

A: OPA820IDR, OPA820IDG4, OPA690ID, and AD8037ARZ-REEL7 are ROHS3 compliant. The original EL5102IS is RoHS non-compliant. For applications requiring RoHS compliance, any of the four compliant substitutes are suitable.

Q: What is the impact of the reduced slew rate in OPA820IDR compared to EL5102IS?

A: The EL5102IS operates at 4000V/µs while OPA820IDR operates at 240V/µs. This reduction affects the maximum rate of voltage change the amplifier can produce. Applications requiring rapid transient response or high-frequency pulse generation may require the OPA690ID (1800V/µs) instead.

Q: Can the supply voltage range difference affect substitution?

A: The EL5102IS operates from 3V to 13.2V, while most substitutes operate from 5V to 12V. If the application requires operation below 5V supply voltage, the EL5102IS specifications cannot be fully replicated. Verify supply voltage requirements before final part selection.

Q: What is the significance of the input bias current difference?

A: The EL5102IS specifies 2µA input bias current, while OPA820 variants specify 9µA. Higher input bias current may affect precision applications requiring very low input current. For general-purpose amplification, this difference is typically not critical.

Q: Is packaging format identical across all parts?

A: All parts use 8-SOIC (0.154", 3.90mm Width) surface mount packaging. Mechanical compatibility is maintained across all substitutes. Packaging format does not differentiate substitution suitability.

Q: Why is AD8037ARZ-REEL7 supplied in Tape & Reel format?

A: Tape & Reel packaging is standard for high-volume production environments. This format does not affect electrical performance or compatibility; it is a supply and handling consideration for manufacturing operations.
