Part Overview

The EL5411IRE is a voltage feedback operational amplifier manufactured by Renesas Electronics Corporation, configured as a 4-circuit rail-to-rail amplifier in a 14-HTSSOP surface mount package. This device is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design support and production requirements. The EL5411IRE operates across a supply voltage range of 4.5 V to 16.5 V with a slew rate of 75 V/µs and gain bandwidth product of 32 MHz, making it suitable for applications requiring moderate-speed signal conditioning and amplification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL5411IRE is determined by the following critical parameters: package compatibility (14-TSSOP surface mount), circuit count (4 independent amplifiers), output configuration (rail-to-rail), and supply voltage range overlap. The EL5411IRE operates with a minimum supply voltage of 4.5 V and maximum of 16.5 V. Substitute parts must accommodate this voltage range or a subset thereof, maintain the same pinout and package footprint, and provide equivalent or superior electrical performance in the application context.

The identified substitute parts are classified into two functional categories:

General Purpose Amplifiers (MCP6H04 Series): These devices provide lower slew rate (0.8 V/µs) and gain bandwidth product (1.2 MHz) compared to the EL5411IRE but maintain 4-circuit rail-to-rail configuration in identical 14-TSSOP packaging. These substitutes are suitable for applications where the EL5411IRE's higher bandwidth is not required.

General Purpose Amplifiers with Enhanced Performance (TLC2274EPWRQ1): This Texas Instruments device provides intermediate slew rate (3.6 V/µs) and gain bandwidth product (2.18 MHz), with superior input bias current (1 pA) and lower input offset voltage (300 µV). This part includes automotive qualification (AEC-Q100) and operates across 4.5 V to 16 V supply range.

Parameter Comparison

Engineering Selection Recommendations

MCP6H04-E/ST and MCP6H04T-E/ST (Microchip Technology): These devices are recommended for applications where the EL5411IRE's high slew rate and bandwidth are not required. Both parts are ROHS3 compliant with MSL 1 rating, providing superior moisture handling compared to the obsolete EL5411IRE. The MCP6H04T-E/ST is supplied in Tape & Reel packaging with 3800 units in stock, while the MCP6H04-E/ST is supplied in Tube packaging with 2918 units available. Both operate across 3.5 V to 16 V supply range, encompassing the EL5411IRE's minimum requirement of 4.5 V. The significantly lower supply current (135 µA versus 10 mA per channel) makes these substitutes advantageous for power-constrained applications.

TLC2274EPWRQ1 (Texas Instruments): This device is recommended for applications requiring higher performance than the MCP6H04 series while maintaining compatibility with the EL5411IRE's 4.5 V minimum supply voltage. The TLC2274EPWRQ1 provides superior input characteristics (1 pA bias current, 300 µV offset voltage) and intermediate slew rate (3.6 V/µs). This part carries AEC-Q100 automotive qualification and operates across -40°C to 150°C, extending the upper temperature limit beyond the EL5411IRE. ROHS3 compliance and MSL 2 rating are provided. Inventory of 2236 units is available in Cut Tape packaging.

All three substitute parts maintain identical 14-TSSOP package geometry and pinout compatibility with the EL5411IRE, enabling direct footprint substitution. Selection between substitutes depends on application bandwidth requirements, supply current constraints, and temperature operating range specifications.

Frequently Asked Questions (FAQ)

Q: Can the MCP6H04 series directly replace the EL5411IRE in existing designs?

A: The MCP6H04-E/ST and MCP6H04T-E/ST provide identical pinout and 14-TSSOP package footprint compatibility with the EL5411IRE. However, the significantly lower slew rate (0.8 V/µs versus 75 V/µs) and gain bandwidth product (1.2 MHz versus 32 MHz) require verification that the application does not depend on the EL5411IRE's higher-speed performance characteristics. Supply voltage range compatibility exists for applications operating at 4.5 V or higher.

Q: What are the key differences between MCP6H04-E/ST and MCP6H04T-E/ST?

A: Both devices are electrically identical with identical electrical specifications. The primary difference is packaging format: MCP6H04-E/ST is supplied in Tube packaging, while MCP6H04T-E/ST is supplied in Tape & Reel (TR) format. Selection depends on production assembly requirements and inventory management preferences.

Q: Is the TLC2274EPWRQ1 suitable for automotive applications?

A: The TLC2274EPWRQ1 carries AEC-Q100 automotive qualification and is designated as an automotive-grade component. This qualification applies to the specific part number and packaging configuration provided. Applications requiring automotive qualification should confirm that this part meets all relevant automotive standards for the specific end application.

Q: What is the impact of lower supply current in the MCP6H04 series?

A: The MCP6H04 series operates at 135 µA per channel (540 µA total for 4 channels) compared to 10 mA per channel (40 mA total) for the EL5411IRE. This represents a 74-fold reduction in supply current, resulting in significantly lower power dissipation. Applications with power budget constraints benefit from this reduction, though the lower bandwidth may limit use in high-frequency signal processing.

Q: Are all substitute parts RoHS compliant?

A: The MCP6H04-E/ST, MCP6H04T-E/ST, and TLC2274EPWRQ1 are all ROHS3 compliant. The original EL5411IRE is RoHS non-compliant. Designs requiring RoHS compliance must transition to one of the substitute parts.

Q: What is the significance of Moisture Sensitivity Level (MSL) differences?

A: The EL5411IRE carries MSL 3 rating (168-hour floor life), requiring careful handling and storage. The MCP6H04 series carries MSL 1 rating (unlimited floor life), eliminating moisture sensitivity concerns. The TLC2274EPWRQ1 carries MSL 2 rating (1-year floor life). Lower MSL ratings reduce manufacturing process constraints and storage requirements.

Q: Can the TLC2274EPWRQ1 operate at the EL5411IRE's maximum supply voltage of 16.5 V?

A: The TLC2274EPWRQ1 is specified for maximum supply voltage of 16 V. Applications requiring operation at 16.5 V must use the MCP6H04 series (16 V maximum) or confirm that 16 V operation is acceptable for the specific application. The 0.5 V difference may be within design margin for many applications.

Q: What is the operating temperature range difference between substitutes?

A: The EL5411IRE operates from -40°C to 85°C. The MCP6H04 series extends to -40°C to 125°C, and the TLC2274EPWRQ1 extends to -40°C to 150°C. Applications requiring operation above 85°C must use one of the substitute parts. The extended upper temperature limit of the TLC2274EPWRQ1 is particularly advantageous for high-temperature environments.
