EL5293CS-T7 Equivalent & Substitute Parts

Part Overview

The EL5293CS-T7 is a current feedback amplifier integrated circuit manufactured by Renesas Electronics Corporation, configured as a dual-channel operational amplifier in an 8-SOIC surface mount package. This device is classified as obsolete, indicating it is no longer in active production. Due to its obsolete status, equivalent substitute parts from active product lines are necessary for new designs, production continuity, and long-term component availability assurance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EL5293CS-T7 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Amplifier Type: Current Feedback (all substitutes must match)
• Number of Circuits: 2 (dual-channel configuration required)
• Package / Case: 8-SOIC form factor (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Operational Parameter Ranges:

• Operating Temperature: -40°C ~ 85°C (minimum requirement)
• Voltage - Supply Span: Must accommodate 5V to 10V range
• Current - Output / Channel: Must support minimum 120 mA
• Current - Supply: Must support 4mA per channel operation

The substitute parts AD8002ARZ, AD8002ARZ-R7, and LT1396CS8#PBF satisfy the mandatory compatibility criteria and operate within the required parameter ranges, though with variations in specific electrical characteristics such as slew rate, bandwidth, and supply current specifications.

Parameter Comparison

Engineering Selection Recommendations

AD8002ARZ and AD8002ARZ-R7 (Analog Devices Inc.)

Both AD8002ARZ variants are functionally equivalent current feedback amplifiers with active product status. These devices provide higher bandwidth (600 MHz) and lower slew rate (1200V/µs) compared to the EL5293CS-T7. The minimum supply voltage requirement is 6V, which is compatible with the EL5293CS-T7 operating range. Output current per channel is 70 mA, which is lower than the original specification of 120 mA. Both variants are ROHS3 compliant and suitable for new designs requiring regulatory compliance. The AD8002ARZ-R7 is supplied in Tape & Reel packaging, while the AD8002ARZ is supplied in Tube packaging.

LT1396CS8#PBF (Analog Devices Inc.)

The LT1396CS8#PBF is a current feedback amplifier with active product status and ROHS3 compliance. This device operates with a minimum supply voltage of 4V, providing broader supply compatibility. The slew rate is 800V/µs and bandwidth is 400 MHz. Output current per channel is 80 mA. The operating temperature range is 0°C ~ 70°C, which is narrower than the EL5293CS-T7 specification of -40°C ~ 85°C. This device is suitable for applications where the reduced temperature range is acceptable and lower slew rate performance is tolerable.

All three substitute parts maintain the dual-channel current feedback amplifier architecture and 8-SOIC package form factor, ensuring mechanical and electrical compatibility with existing PCB layouts designed for the EL5293CS-T7.

Frequently Asked Questions (FAQ)

Q: Can the AD8002ARZ directly replace the EL5293CS-T7 in existing designs?

A: The AD8002ARZ is mechanically and functionally compatible as a current feedback amplifier in the same 8-SOIC package. However, electrical parameter differences exist. The output current per channel is 70 mA versus 120 mA on the original part. The minimum supply voltage is 6V versus 5V. Circuit validation is required to confirm performance in the specific application.

Q: What is the difference between AD8002ARZ and AD8002ARZ-R7?

A: Both parts are electrically identical current feedback amplifiers with the same electrical specifications. The primary difference is packaging: AD8002ARZ is supplied in Tube packaging, while AD8002ARZ-R7 is supplied in Tape & Reel (TR) packaging. Selection depends on assembly process requirements and volume considerations.

Q: Is the LT1396CS8#PBF suitable for applications requiring -40°C operation?

A: No. The LT1396CS8#PBF has an operating temperature range of 0°C ~ 70°C, which does not include -40°C. The EL5293CS-T7 and both AD8002ARZ variants support -40°C ~ 85°C operation. For applications requiring -40°C operation, use AD8002ARZ or AD8002ARZ-R7.

Q: Are all substitute parts RoHS compliant?

A: Yes. AD8002ARZ, AD8002ARZ-R7, and LT1396CS8#PBF are all ROHS3 compliant. The original EL5293CS-T7 is RoHS non-compliant. Substitution with any of these parts satisfies RoHS compliance requirements for new designs.

Q: What is the impact of lower output current on the substitute parts?

A: The AD8002ARZ and AD8002ARZ-R7 provide 70 mA per channel output current, compared to 120 mA on the EL5293CS-T7. The LT1396CS8#PBF provides 80 mA per channel. Applications requiring output currents exceeding these limits require circuit redesign or alternative component selection.

Q: Can I use these substitutes in high-frequency applications?

A: The AD8002ARZ variants offer 600 MHz bandwidth, which exceeds the EL5293CS-T7 specification of 300 MHz. The LT1396CS8#PBF provides 400 MHz bandwidth. All three substitutes are suitable for high-frequency applications within their specified bandwidth limits.

Q: What supply voltage range should I use for compatibility?

A: The EL5293CS-T7 operates from 5V to 10V. The AD8002ARZ variants require 6V to 12V minimum. The LT1396CS8#PBF operates from 4V to 12V. For designs using 5V supply, only the LT1396CS8#PBF provides full compatibility. Designs using 6V or higher supply voltage are compatible with all three substitutes.
