EL5410CSZ Equivalent & Substitute Parts

Part Overview

The EL5410CSZ is a voltage feedback operational amplifier manufactured by Renesas Electronics Corporation, configured as a 4-circuit integrated circuit in a 14-SOIC surface mount package. This device features rail-to-rail output capability and is designed for general-purpose analog signal processing applications requiring moderate bandwidth and low input bias current.

The EL5410CSZ is classified as obsolete. Identification of equivalent and substitute parts is necessary to support ongoing system maintenance, design updates, and procurement continuity where original components are no longer available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL5410CSZ is determined by the following critical parameters that must be maintained or exceeded in the replacement device:

Mechanical Compatibility:

• Package type: 14-SOIC surface mount configuration with 0.154" (3.90mm) width
• Pin count and pinout arrangement must be identical

Functional Requirements:

• Number of circuits: 4 independent amplifier channels
• Output configuration: Rail-to-rail output capability
• Mounting type: Surface mount technology

Electrical Operating Range:

• Supply voltage span must encompass the original range (4.5 V minimum to 16.5 V maximum)
• Operating temperature range must support -40°C to 85°C minimum

Regulatory and Compliance:

• RoHS3 compliance required
• REACH unaffected status required

The OPA4354AIDR from Texas Instruments satisfies these substitution criteria through identical package configuration, matching circuit count, rail-to-rail output architecture, and equivalent regulatory compliance status.

Engineering Selection Recommendations

OPA4354AIDR as Primary Substitute:

The OPA4354AIDR is suitable as a substitute for the EL5410CSZ based on the following factors:

Mechanical Compatibility: Both devices utilize identical 14-SOIC surface mount packaging with matching pin configurations, enabling direct board-level replacement without layout modifications.

Regulatory Compliance: The OPA4354AIDR maintains ROHS3 compliance and REACH unaffected status, satisfying the same environmental and regulatory requirements as the original EL5410CSZ.

Product Availability: The OPA4354AIDR is classified as active product status with substantial inventory availability (50,200 units), ensuring reliable procurement compared to the obsolete EL5410CSZ.

Electrical Performance Characteristics: The OPA4354AIDR provides enhanced performance specifications across multiple parameters, including higher slew rate (150 V/µs versus 33 V/µs), increased gain bandwidth product (100 MHz versus 20 MHz), and superior input bias current characteristics (3 pA versus 2 nA). These improvements represent performance enhancements rather than degradation.

Operating Range Considerations: The OPA4354AIDR operates within a reduced supply voltage range (2.5 V to 5.5 V) compared to the EL5410CSZ (4.5 V to 16.5 V). Circuit designs utilizing supply voltages above 5.5 V require alternative solutions or supply voltage regulation to accommodate this substitute.

Moisture Sensitivity: The OPA4354AIDR features improved moisture sensitivity level (MSL 2, 1 Year) compared to the EL5410CSZ (MSL 3, 168 Hours), providing enhanced handling and storage characteristics.

Frequently Asked Questions (FAQ)

Q: Can the OPA4354AIDR be used as a direct replacement for the EL5410CSZ in existing circuit designs?

A: The OPA4354AIDR provides mechanical and functional compatibility through identical 14-SOIC packaging and matching 4-circuit configuration. However, circuit designs must operate within the OPA4354AIDR supply voltage range of 2.5 V to 5.5 V. Designs utilizing supply voltages above 5.5 V require circuit modification or external voltage regulation.

Q: What are the key differences between the EL5410CSZ and OPA4354AIDR?

A: The primary differences are amplifier architecture (voltage feedback versus CMOS), performance specifications (slew rate, bandwidth, input bias current), and supply voltage operating range. The OPA4354AIDR provides superior performance across bandwidth and slew rate parameters but operates within a narrower supply voltage range.

Q: Are both devices available in the same package configuration?

A: Yes. Both the EL5410CSZ and OPA4354AIDR are manufactured in 14-SOIC surface mount packages with identical physical dimensions (0.154" width, 3.90mm). Pin-to-pin compatibility enables direct board-level substitution from a mechanical perspective.

Q: Do both devices meet the same regulatory compliance standards?

A: Yes. Both the EL5410CSZ and OPA4354AIDR are ROHS3 compliant and REACH unaffected, satisfying equivalent environmental and regulatory requirements.

Q: What is the impact of the different moisture sensitivity levels?

A: The OPA4354AIDR features MSL 2 (1 Year) compared to the EL5410CSZ MSL 3 (168 Hours). This represents improved moisture tolerance, reducing the risk of moisture-related failures during storage and handling. The OPA4354AIDR requires less stringent moisture control during manufacturing and assembly processes.

Q: How do the input bias current specifications compare?

A: The OPA4354AIDR input bias current is 3 pA compared to the EL5410CSZ at 2 nA. The OPA4354AIDR provides approximately 667 times lower input bias current, resulting in reduced input current errors and improved performance in high-impedance signal conditioning applications.

Q: What supply voltage considerations apply when substituting these devices?

A: The EL5410CSZ operates from 4.5 V to 16.5 V, while the OPA4354AIDR operates from 2.5 V to 5.5 V. Circuits designed for supply voltages exceeding 5.5 V cannot use the OPA4354AIDR without external voltage regulation or alternative component selection.
