EL5106IS-T13 Equivalent & Substitute Parts

Part Overview

The EL5106IS-T13 is a general purpose operational amplifier manufactured by Renesas Electronics Corporation in an 8-SOIC surface mount package. This device is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. The EL5106IS-T13 delivers a slew rate of 4500 V/µs with a -3dB bandwidth of 380 MHz, suitable for general purpose amplification applications requiring moderate to high-speed performance. Due to its obsolete status, alternative components with compatible electrical and mechanical specifications are necessary for new designs and legacy system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL5106IS-T13 is determined by compatibility across the following critical parameters:

Package Compatibility: The substitute part must utilize an 8-SOIC surface mount package with identical 0.154" (3.90mm) width to ensure direct PCB footprint compatibility without layout modifications.

Electrical Performance Envelope: The substitute must operate within the supply voltage range of 5 V to 12 V and maintain the operating temperature range of -40°C to 85°C. The substitute must support single-circuit amplifier configuration.

Functional Classification: While the EL5106IS-T13 is classified as a general purpose amplifier, substitute parts may include voltage feedback amplifiers and other linear amplifier topologies that satisfy the electrical and mechanical constraints.

Performance Characteristics: Substitutes must demonstrate slew rate and bandwidth performance suitable for applications originally designed for the EL5106IS-T13. Input bias current, input offset voltage, supply current, and output current specifications must be evaluated for circuit-level compatibility.

The OPA656U from Texas Instruments satisfies package and supply voltage requirements and is identified as a direct substitute based on these parameters.

Engineering Selection Recommendations

Product Status Consideration: The EL5106IS-T13 is classified as obsolete, while the OPA656U is designated as Last Time Buy. The OPA656U provides extended availability compared to the primary part, supporting design continuity for legacy systems and new production runs.

Compliance Status: The OPA656U is ROHS3 compliant, whereas the EL5106IS-T13 is RoHS non-compliant. This distinction is significant for applications subject to regulatory requirements or customer specifications mandating RoHS compliance. Both parts are REACH Unaffected and carry EAR99 export classification.

Electrical Performance Trade-offs: The OPA656U exhibits lower slew rate (295 V/µs versus 4500 V/µs) but higher -3dB bandwidth (500 MHz versus 380 MHz). The OPA656U demonstrates superior input offset voltage (0.25 mV versus 1 mV) and significantly lower input bias current (2 pA versus 1.5 µA). Supply current consumption is higher in the OPA656U (14 mA versus 1.5 mA), while output current capability is lower (70 mA versus 100 mA).

Supply Voltage Compatibility: The OPA656U requires a minimum supply voltage of 8 V, compared to 5 V for the EL5106IS-T13. Applications operating at supply voltages below 8 V are not compatible with the OPA656U substitute.

Package and Mounting: Both devices utilize identical 8-SOIC surface mount packaging, enabling direct PCB footprint compatibility without layout redesign.

Frequently Asked Questions (FAQ)

Q: Can the OPA656U directly replace the EL5106IS-T13 in all applications?

A: Direct replacement requires verification of supply voltage compatibility. The OPA656U operates at a minimum of 8 V, whereas the EL5106IS-T13 operates at 5 V minimum. Applications using 5 V to 7.9 V supply rails are not compatible with the OPA656U. Additionally, applications requiring the higher slew rate of the EL5106IS-T13 (4500 V/µs) must evaluate whether the OPA656U slew rate (295 V/µs) is acceptable for the intended circuit function.

Q: Are there mechanical compatibility concerns between these parts?

A: No. Both the EL5106IS-T13 and OPA656U utilize identical 8-SOIC surface mount packages with 0.154" (3.90mm) width. PCB footprints, solder pad layouts, and mounting procedures are identical, eliminating mechanical redesign requirements.

Q: What is the significance of the product status difference?

A: The EL5106IS-T13 is obsolete, indicating no further manufacturing or availability. The OPA656U is designated Last Time Buy, meaning limited quantities remain available from the manufacturer before discontinuation. For new designs or long-term production, the OPA656U provides extended but finite availability compared to the obsolete EL5106IS-T13.

Q: How do the input bias current specifications compare?

A: The EL5106IS-T13 specifies 1.5 µA input bias current, while the OPA656U specifies 2 pA input bias current. The OPA656U exhibits approximately 750 times lower input bias current, which is advantageous for high-impedance input circuits and reduces input offset current effects. Applications sensitive to input bias current may benefit from the OPA656U characteristics.

Q: What are the supply current implications of substitution?

A: The OPA656U requires 14 mA supply current compared to 1.5 mA for the EL5106IS-T13. This represents a 9.3× increase in quiescent current consumption. Power supply design and thermal management must accommodate this higher current draw in battery-powered or power-constrained applications.

Q: Does RoHS compliance status affect substitution decisions?

A: RoHS compliance is a regulatory and customer specification consideration. The OPA656U is ROHS3 compliant, while the EL5106IS-T13 is RoHS non-compliant. Applications subject to RoHS requirements or customer mandates must use the OPA656U or identify alternative compliant substitutes. Legacy systems without RoHS requirements may use either part based on availability and electrical compatibility.

Q: What output current capability differences exist?

A: The EL5106IS-T13 provides 100 mA output current per channel, while the OPA656U provides 70 mA. Applications requiring output currents between 70 mA and 100 mA must evaluate whether the OPA656U output capability is sufficient or whether external buffering is necessary.
