Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL5412IRZ is determined by the following critical parameters that must be maintained or exceeded:

Package Compatibility: The substitute must use 14-TSSOP or 14-HTSSOP surface mount packaging with identical 0.173" (4.40mm) width to ensure PCB footprint compatibility.

Circuit Configuration: The substitute must provide four independent operational amplifier circuits to maintain functional equivalence in multi-channel applications.

Output Capability: Rail-to-rail output type is required to preserve signal swing characteristics across the specified supply voltage range.

Supply Voltage Range: The substitute must support the minimum 4.5V and maximum 16.5V supply span to ensure operation in the same power distribution environments.

Electrical Performance: The substitute must meet or exceed the slew rate (55V/µs), gain bandwidth product (22 MHz), and output current per channel (65 mA) to maintain signal fidelity and drive capability.

Compliance Requirements: RoHS3 compliance and REACH unaffected status are mandatory for regulatory alignment.

Based on these criteria, the TLC2274EPWRQ1 from Texas Instruments qualifies as a substitute part. The TLV2374QPWRRB is excluded from substitution consideration due to incomplete technical specification data in the provided parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TLC2274EPWRQ1

The TLC2274EPWRQ1 is the qualified substitute for the obsolete EL5412IRZ based on the following engineering criteria:

Package Compatibility: Both devices use identical 14-TSSOP surface mount packaging with 0.173" (4.40mm) width, enabling direct PCB footprint replacement without layout modifications.

Functional Equivalence: Both devices provide four independent rail-to-rail operational amplifier circuits, maintaining the multi-channel architecture required for existing designs.

Supply Voltage Compatibility: The TLC2274EPWRQ1 supports 4.5V to 16V operation, which encompasses the primary operating range of the EL5412IRZ. Applications requiring the maximum 16.5V supply of the original part require design verification.

Product Status and Support: The TLC2274EPWRQ1 is active and in production, ensuring long-term availability and technical support compared to the obsolete EL5412IRZ.

Compliance Alignment: Both devices are ROHS3 compliant and REACH unaffected, maintaining regulatory requirements for new production.

Automotive Grade Qualification: The TLC2274EPWRQ1 carries AEC-Q100 automotive qualification and operates across -40°C to 150°C, providing enhanced reliability for extended temperature applications.

Performance Trade-offs: The TLC2274EPWRQ1 exhibits lower slew rate (3.6V/µs versus 55V/µs) and reduced gain bandwidth product (2.18 MHz versus 22 MHz). Applications requiring high-speed signal conditioning or fast transient response must evaluate whether these reduced performance parameters are acceptable for the intended circuit function.

Handling Considerations: The TLC2274EPWRQ1 has MSL 2 (1 Year) moisture sensitivity compared to MSL 1 (Unlimited) for the EL5412IRZ, requiring stricter moisture control during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can the TLC2274EPWRQ1 directly replace the EL5412IRZ without PCB modifications?

A: Yes, the TLC2274EPWRQ1 uses the same 14-TSSOP package with identical 0.173" (4.40mm) width, enabling direct footprint replacement. However, circuit performance characteristics differ, requiring functional validation before production implementation.

Q: What are the key performance differences between the EL5412IRZ and TLC2274EPWRQ1?

A: The EL5412IRZ provides higher slew rate (55V/µs versus 3.6V/µs), higher gain bandwidth product (22 MHz versus 2.18 MHz), and higher output current per channel (65 mA versus 50 mA). The TLC2274EPWRQ1 offers superior input offset voltage (300 µV versus 3 mV) and input bias current (1 pA versus 2 nA). Application requirements determine which device is appropriate.

Q: Is the TLC2274EPWRQ1 suitable for high-speed signal conditioning applications?

A: The TLC2274EPWRQ1 is classified as a general-purpose amplifier with lower bandwidth performance than the EL5412IRZ. Applications requiring slew rates above 3.6V/µs or bandwidth above 2.18 MHz require alternative component selection or circuit redesign.

Q: What supply voltage range must be verified when substituting the TLC2274EPWRQ1?

A: The TLC2274EPWRQ1 supports 4.5V to 16V operation. The EL5412IRZ supports 4.5V to 16.5V. Designs operating at 16.5V supply voltage require verification that the TLC2274EPWRQ1 meets performance specifications at the reduced maximum supply voltage of 16V.

Q: Are there moisture sensitivity differences between these devices?

A: Yes. The EL5412IRZ has MSL 1 (Unlimited) moisture sensitivity, while the TLC2274EPWRQ1 has MSL 2 (1 Year). The TLC2274EPWRQ1 requires stricter moisture control during storage, with a one-year shelf life limit under specified humidity conditions.

Q: Does the TLC2274EPWRQ1 meet automotive qualification requirements?

A: Yes, the TLC2274EPWRQ1 carries AEC-Q100 automotive qualification and is suitable for automotive applications. The EL5412IRZ does not specify automotive qualification.

Q: What is the operating temperature range difference?

A: The EL5412IRZ operates from -40°C to 85°C, while the TLC2274EPWRQ1 operates from -40°C to 150°C. The TLC2274EPWRQ1 supports extended high-temperature operation for applications requiring operation above 85°C.

Q: Why is the TLV2374QPWRRB not listed as a substitute?

A: The TLV2374QPWRRB has incomplete technical specification data in the provided parameters. Substitution determination requires complete electrical performance, package, and compliance information. This device cannot be evaluated against the substitution criteria without full technical documentation.

Q: What compliance certifications are maintained with the TLC2274EPWRQ1 substitute?

A: Both the EL5412IRZ and TLC2274EPWRQ1 are ROHS3 compliant and REACH unaffected. The TLC2274EPWRQ1 additionally carries AEC-Q100 automotive qualification. All regulatory requirements are maintained with this substitution.
