EL2045CSZ Equivalent & Substitute Parts

Part Overview

The EL2045CSZ is a voltage feedback amplifier manufactured by Renesas Electronics Corporation, housed in an 8-SOIC surface mount package. This linear amplifier integrates one circuit and is designed for applications requiring moderate bandwidth and slew rate performance. The EL2045CSZ is classified as obsolete, making identification of functionally equivalent substitute components necessary for ongoing design support, production continuity, and system maintenance. Substitute parts must maintain electrical compatibility across key performance parameters while meeting current availability and compliance requirements.

Substitute Part Grouping Explanation

Substitute components for the EL2045CSZ are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is based on the following parameters:

Mechanical Compatibility:

• Identical package type: 8-SOIC surface mount
• Identical package dimensions: 0.154" width, 3.90mm width
• Surface mount mounting type

Electrical Compatibility:

• Amplifier topology: Voltage feedback architecture
• Single circuit configuration
• Operating temperature range: -40°C to 85°C
• Supply voltage range overlap or compatibility
• Slew rate and bandwidth performance within acceptable operational margins
• Input bias current and input offset voltage characteristics suitable for equivalent circuit operation

Compliance and Status:

• RoHS3 compliance maintained
• REACH unaffected status
• Active product status preferred for ongoing availability

The THS4011ID from Texas Instruments meets these substitution criteria through identical package specifications, matching amplifier topology, compatible operating temperature range, and maintained compliance certifications.

Engineering Selection Recommendations

Primary Substitute: THS4011ID

The THS4011ID is the qualified substitute for the obsolete EL2045CSZ based on the following engineering criteria:

Mechanical Compatibility: The THS4011ID maintains identical 8-SOIC surface mount packaging with matching 0.154" (3.90mm) width specifications, ensuring direct PCB footprint compatibility without layout modifications.

Electrical Compatibility: Both devices implement voltage feedback amplifier topology with single circuit configuration and identical -40°C to 85°C operating temperature range. The THS4011ID demonstrates enhanced performance characteristics: higher slew rate (310 V/µs versus 275 V/µs), increased gain bandwidth product (290 MHz versus 200 MHz), and lower input bias current (2 µA versus 2.8 µA). These performance improvements are compatible with applications designed for the EL2045CSZ.

Supply Voltage Consideration: The EL2045CSZ operates across 2.5 V to 36 V supply range, while the THS4011ID operates across 9 V to 32 V supply range. Applications utilizing the EL2045CSZ at supply voltages below 9 V require circuit redesign or alternative component selection.

Compliance and Availability: The THS4011ID maintains ROHS3 compliance and REACH unaffected status, matching the EL2045CSZ compliance profile. Active product status ensures ongoing availability and manufacturing support, addressing the obsolescence of the original component.

Frequently Asked Questions (FAQ)

Q: Can the THS4011ID directly replace the EL2045CSZ without PCB modifications?

A: Yes, for applications operating within the THS4011ID supply voltage range (9 V to 32 V). Both devices use identical 8-SOIC surface mount packages with matching pinout and footprint dimensions, enabling direct component substitution on the PCB. Applications utilizing supply voltages below 9 V require circuit redesign.

Q: What are the key performance differences between these devices?

A: The THS4011ID provides enhanced performance across multiple parameters: slew rate increases from 275 V/µs to 310 V/µs, gain bandwidth product increases from 200 MHz to 290 MHz, and input bias current decreases from 2.8 µA to 2 µA. Input offset voltage increases from 500 µV to 1 mV, and supply current increases from 5.2 mA to 7.8 mA. These differences are compatible with applications designed for the EL2045CSZ.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both the EL2045CSZ and THS4011ID maintain ROHS3 compliance and REACH unaffected status. Compliance certifications are equivalent across both components.

Q: What is the primary reason for substitution?

A: The EL2045CSZ is classified as obsolete, making long-term availability uncertain. The THS4011ID is an active product from a major manufacturer, ensuring continued availability, manufacturing support, and supply chain reliability.

Q: Are there supply voltage limitations for substitution?

A: Yes. The EL2045CSZ supports supply voltages from 2.5 V to 36 V, while the THS4011ID requires minimum 9 V supply. Applications operating the EL2045CSZ at supply voltages below 9 V cannot use the THS4011ID as a direct substitute without circuit modifications.

Q: How do the packaging specifications compare?

A: Both devices are housed in 8-SOIC surface mount packages with identical dimensions: 0.154" width and 3.90mm width. Pinout and footprint are identical, enabling direct PCB substitution without layout changes.
