Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL2045CSZ-T13 is determined by strict alignment of the following electrical and mechanical parameters:

Mandatory Matching Criteria:

• Amplifier topology: Voltage feedback architecture
• Circuit count: Single circuit configuration
• Package type: 8-SOIC surface mount form factor with 0.154" (3.90mm) width
• Operating temperature range: -40°C to 85°C minimum
• RoHS3 compliance status

Performance Parameters Evaluated:

• Slew rate (275 V/µs baseline)
• Gain bandwidth product (200 MHz baseline)
• Input bias current (2.8 µA baseline)
• Input offset voltage (500 µV baseline)
• Supply current (5.2 mA baseline)
• Output current capability (75 mA baseline)
• Supply voltage range (2.5 V to 36 V baseline)

The THS4011ID from Texas Instruments meets all mandatory matching criteria and operates within the same functional class. This part maintains the 8-SOIC package geometry, surface mount configuration, and temperature operating range. Performance specifications exceed the baseline EL2045CSZ-T13 across slew rate, gain bandwidth product, and -3dB bandwidth metrics, while maintaining compatibility with the same supply voltage envelope and output current requirements.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The EL2045CSZ-T13 is classified as obsolete, indicating discontinued manufacturing and limited long-term availability. The THS4011ID maintains active product status with Texas Instruments, ensuring ongoing supply chain access and manufacturing support.

Compliance and Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for equivalent deployment. The THS4011ID carries Moisture Sensitivity Level 1 (unlimited), compared to the EL2045CSZ-T13 MSL 3 (168 hours), providing superior handling flexibility during storage and assembly operations.

Performance Envelope: The THS4011ID delivers enhanced performance across bandwidth and slew rate specifications, making it suitable for applications where the EL2045CSZ-T13 was previously specified. The higher gain bandwidth product (290 MHz versus 200 MHz) and slew rate (310 V/µs versus 275 V/µs) provide design margin for signal fidelity and transient response.

Supply Voltage Compatibility: The THS4011ID minimum supply voltage requirement is 9 V, compared to 2.5 V for the EL2045CSZ-T13. Applications operating at supply voltages below 9 V require circuit redesign or alternative component selection. The maximum supply voltage of 32 V for the THS4011ID remains within the 36 V maximum of the EL2045CSZ-T13, maintaining upper voltage envelope compatibility.

Electrical Characteristics: Input bias current is lower in the THS4011ID (2 µA versus 2.8 µA), reducing input loading effects. Input offset voltage is higher (1 mV versus 500 µV), requiring offset nulling consideration in precision applications. Supply current consumption increases from 5.2 mA to 7.8 mA, affecting power budget calculations.

Frequently Asked Questions (FAQ)

Q: Can the THS4011ID directly replace the EL2045CSZ-T13 in existing PCB layouts?

A: Yes, both parts use identical 8-SOIC surface mount packaging with 0.154" (3.90mm) width. Pin-to-pin compatibility and footprint alignment are maintained. No PCB redesign is required for physical substitution.

Q: What is the primary reason the EL2045CSZ-T13 requires substitution?

A: The EL2045CSZ-T13 carries obsolete product status, indicating discontinued manufacturing by Renesas Electronics Corporation. Long-term component availability cannot be assured. The THS4011ID, with active product status, provides reliable supply chain continuity.

Q: Are there supply voltage limitations when substituting to the THS4011ID?

A: Yes. The THS4011ID requires a minimum supply voltage of 9 V, compared to 2.5 V for the EL2045CSZ-T13. Applications operating below 9 V cannot use the THS4011ID without circuit modification. The maximum supply voltage of 32 V (THS4011ID) versus 36 V (EL2045CSZ-T13) is not a practical limitation for most applications.

Q: How do the input offset voltage specifications differ between these parts?

A: The EL2045CSZ-T13 specifies 500 µV input offset voltage, while the THS4011ID specifies 1 mV. For precision applications requiring offset nulling, the THS4011ID may require additional calibration circuitry or offset adjustment techniques to achieve equivalent performance.

Q: What is the impact of increased supply current in the THS4011ID?

A: The THS4011ID draws 7.8 mA compared to 5.2 mA for the EL2045CSZ-T13, an increase of 2.6 mA per channel. Power supply design and thermal management calculations must account for this additional current draw. For single-channel applications, this represents a 50% increase in amplifier supply current.

Q: Does the THS4011ID provide performance advantages over the EL2045CSZ-T13?

A: Yes. The THS4011ID delivers higher slew rate (310 V/µs versus 275 V/µs), higher gain bandwidth product (290 MHz versus 200 MHz), and higher -3dB bandwidth (290 MHz versus 100 MHz). These enhancements provide improved transient response and signal fidelity for bandwidth-limited applications.

Q: What is the significance of the Moisture Sensitivity Level difference?

A: The EL2045CSZ-T13 carries MSL 3 (168 hours), requiring controlled humidity storage and limited floor life after package opening. The THS4011ID carries MSL 1 (unlimited), eliminating moisture sensitivity constraints. This simplifies inventory management and reduces risk of moisture-induced failures during assembly operations.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the EL2045CSZ-T13 and THS4011ID maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for equivalent deployment in regulated applications.
