EL5152IS Equivalent & Substitute Parts

Part Overview

The EL5152IS 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 ongoing design requirements and production continuity. The EL5152IS delivers a single amplifier circuit with a gain bandwidth product of 165 MHz and operates across a 5V to 12V supply range, making it suitable for general-purpose signal conditioning and amplification applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL5152IS is determined by strict adherence to the following electrical and mechanical parameters:

Primary Compatibility Criteria:

• Amplifier Type: Voltage Feedback (single circuit configuration)
• Package / Case: 8-SOIC surface mount form factor
• Operating Temperature Range: -40°C to 85°C minimum
• Supply Voltage Range: Minimum 5V to 12V maximum compatibility
• Mounting Type: Surface Mount

Electrical Performance Considerations: Substitute parts must maintain compatibility within the following parameter bands:

• Gain Bandwidth Product: 165 MHz baseline (substitutes may exceed this specification)
• Slew Rate: 180 V/µs baseline (substitutes may exceed this specification)
• Current - Output / Channel: 105 mA baseline (substitutes must meet or exceed)
• Current - Supply: 3 mA baseline (substitutes may exceed within thermal constraints)

The identified substitute parts—OPA820IDR, OPA842ID, and OPA842IDR—all satisfy the core mechanical and electrical compatibility requirements while offering active product status and enhanced performance characteristics.

Engineering Selection Recommendations

OPA820IDR Selection Criteria: The OPA820IDR represents the optimal substitute for applications requiring minimum supply voltage compatibility at 5V. This device maintains the 5V to 12V supply range of the original EL5152IS while delivering enhanced performance metrics: 240 V/µs slew rate, 280 MHz gain bandwidth product, and 800 MHz -3dB bandwidth. The OPA820IDR exhibits lower input bias current (9 µA versus 120 nA) and reduced input offset voltage (200 µV versus 500 µV). Product status is active with ROHS3 compliance and MSL 2 rating. Packaging is available in Cut Tape and Digi-Reel formats.

OPA842ID and OPA842IDR Selection Criteria: Both OPA842 variants (OPA842ID in Tube packaging and OPA842IDR in standard packaging) deliver the highest slew rate performance at 400 V/µs with 200 MHz gain bandwidth product. These devices require a minimum supply voltage of 10V, restricting use to applications operating within the 10V to 12V range. Supply current consumption is elevated at 20.2 mA compared to the original 3 mA specification. Both variants maintain active product status with ROHS3 compliance and MSL 2 rating. Output current capability (100 mA) remains within acceptable margins of the original specification (105 mA).

Compliance and Regulatory Considerations: All three substitute parts achieve ROHS3 compliance, addressing environmental regulatory requirements absent in the obsolete EL5152IS. REACH status is unaffected across all devices. Moisture sensitivity levels increase from MSL 1 (unlimited) to MSL 2 (1 year), requiring appropriate handling and storage protocols during component procurement and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the OPA820IDR directly replace the EL5152IS in all applications?

A: The OPA820IDR maintains full supply voltage compatibility (5V to 12V) and identical 8-SOIC package specifications. Enhanced performance characteristics (higher slew rate and bandwidth) are backward-compatible with designs specified for the EL5152IS. Pin-level compatibility and functional equivalence are established through voltage feedback amplifier topology. Verification of circuit-specific performance requirements is necessary for applications with tight bandwidth or slew rate constraints.

Q: What are the supply voltage limitations of the OPA842 variants?

A: Both OPA842ID and OPA842IDR require a minimum supply voltage of 10V, compared to the EL5152IS minimum of 5V. Applications operating at 5V to 9.9V supply levels cannot use these substitutes. The OPA820IDR maintains the original 5V minimum specification and is the appropriate selection for low-voltage applications.

Q: How do input bias current differences affect circuit design?

A: The EL5152IS specifies 120 nA input bias current. Substitute parts exhibit higher input bias currents: OPA820IDR at 9 µA and OPA842 variants at 20 µA. Applications with high-impedance input networks or precision transimpedance configurations may require circuit redesign to accommodate increased bias current. Standard inverting and non-inverting amplifier topologies tolerate these differences through proper feedback network design.

Q: Are the substitute parts available in identical packaging formats?

A: All substitute parts utilize the 8-SOIC (0.154", 3.90mm Width) surface mount package, ensuring mechanical compatibility with existing PCB layouts. Packaging format availability differs: OPA820IDR is supplied in Cut Tape and Digi-Reel formats; OPA842ID is supplied in Tube format; OPA842IDR packaging format is not specified. Confirm packaging availability with component suppliers for production requirements.

Q: What is the impact of increased supply current consumption?

A: The EL5152IS draws 3 mA supply current. The OPA820IDR increases this to 5.6 mA, while OPA842 variants consume 20.2 mA. Power supply design and thermal management must accommodate these increased current levels. Applications with strict power budget constraints should prioritize the OPA820IDR to minimize supply current impact.

Q: Do the substitute parts require different PCB layout considerations?

A: All devices share identical 8-SOIC package geometry and surface mount mounting type. PCB layout, trace routing, and decoupling capacitor placement remain consistent with the original EL5152IS design. Increased supply current in OPA842 variants may warrant evaluation of power distribution network adequacy, but fundamental layout principles remain unchanged.

Q: How does the increased input offset voltage of substitutes affect precision applications?

A: The EL5152IS specifies 500 µV input offset voltage. The OPA820IDR reduces this to 200 µV, while OPA842 variants specify 300 µV. For precision DC amplification and instrumentation applications, the OPA820IDR offers superior offset voltage performance. Applications with AC coupling or offset nulling circuits tolerate these variations through standard compensation techniques.
