EL5251IYZ Equivalent & Substitute Parts

Part Overview

The EL5251IYZ is a voltage feedback amplifier integrated circuit manufactured by Renesas Electronics Corporation, configured as a dual-channel (2 circuit) device in an 8-MSOP surface mount package. This component is classified as obsolete, indicating it is no longer in active production. The EL5251IYZ delivers a slew rate of 100V/µs with a gain bandwidth product of 40 MHz, suitable for general-purpose analog signal conditioning applications requiring moderate bandwidth and speed characteristics.

Due to its obsolete status, locating replacement inventory from original sources becomes increasingly difficult. Identifying functionally compatible substitute components ensures design continuity and maintains system performance specifications where the EL5251IYZ is no longer readily available.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL5251IYZ is determined by compatibility across the following critical parameters:

Package and Pinout Compatibility: The substitute component must be housed in an 8-pin surface mount package (8-TSSOP or 8-MSOP configuration) with identical or compatible pinout to ensure direct board-level replacement without layout modifications.

Dual-Channel Configuration: The substitute must contain exactly 2 independent amplifier circuits to match the dual-channel architecture of the EL5251IYZ.

Electrical Performance Envelope: The substitute must operate within the supply voltage range of 5V to 12V and maintain functional performance across the operating temperature range of -40°C to 85°C. Output current capability must meet or exceed 70 mA per channel.

Regulatory and Environmental Compliance: The substitute must maintain ROHS3 compliance and REACH unaffected status to satisfy current manufacturing and environmental regulations.

The OPA2356AIDGKT from Texas Instruments satisfies these substitution criteria, offering enhanced performance characteristics while maintaining package compatibility and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The EL5251IYZ is classified as obsolete, whereas the OPA2356AIDGKT maintains active production status. This distinction ensures long-term availability and supply chain reliability for the substitute component.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements for electronic component manufacturing and deployment.

Certification Alignment: Both devices carry identical moisture sensitivity levels (MSL 2, 1 Year) and equivalent regulatory classifications (ECCN EAR99, HTSUS 8542.33.0001), ensuring compatibility with existing procurement and handling procedures.

Package Compatibility: The OPA2356AIDGKT is supplied in 8-VSSOP packaging, which is mechanically and electrically compatible with the 8-TSSOP/8-MSOP footprint of the EL5251IYZ, permitting direct board-level substitution without PCB redesign.

Supply Voltage Range: The OPA2356AIDGKT operates within a narrower supply voltage range (2.5V to 5.5V) compared to the EL5251IYZ (5V to 12V). Design implementations utilizing supply voltages above 5.5V require verification that the substitute component operates within its specified maximum supply voltage.

Frequently Asked Questions (FAQ)

Q: Can the OPA2356AIDGKT directly replace the EL5251IYZ without PCB modifications?

A: The OPA2356AIDGKT is housed in an 8-VSSOP package with pinout compatibility to the 8-TSSOP/8-MSOP footprint of the EL5251IYZ. Direct board-level substitution is possible without PCB layout changes.

Q: What are the key performance differences between these two components?

A: The OPA2356AIDGKT provides superior performance across multiple parameters: slew rate of 360V/µs versus 100V/µs, gain bandwidth product of 200 MHz versus 40 MHz, and output current of 100 mA per channel versus 70 mA. The OPA2356AIDGKT also exhibits lower input bias current (3 pA versus 20 nA) and extended operating temperature range (-40°C to 125°C versus -40°C to 85°C).

Q: Are there supply voltage compatibility concerns when substituting the OPA2356AIDGKT?

A: The OPA2356AIDGKT operates within a supply voltage range of 2.5V to 5.5V, whereas the EL5251IYZ operates from 5V to 12V. Designs utilizing supply voltages exceeding 5.5V require circuit modification or alternative component selection.

Q: Do both components meet current environmental and regulatory standards?

A: Both the EL5251IYZ and OPA2356AIDGKT maintain ROHS3 compliance and REACH unaffected status. Both components carry identical moisture sensitivity levels (MSL 2, 1 Year), ensuring compatibility with standard handling and storage procedures.

Q: What is the primary reason for substituting the EL5251IYZ?

A: The EL5251IYZ is classified as obsolete and no longer in active production. The OPA2356AIDGKT, maintained in active production status by Texas Instruments, provides assured long-term availability and supply chain continuity.

Q: Does the OPA2356AIDGKT require different circuit design considerations?

A: The OPA2356AIDGKT exhibits higher supply current consumption (8.3mA versus 1.35mA for dual channels) and operates within a narrower supply voltage range. Circuit designs must account for these electrical characteristics during implementation.
