EL5293CSZ Equivalent & Substitute Parts

Part Overview

The EL5293CSZ 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 that Renesas has discontinued production and support. The obsolete status necessitates identification of active equivalent and substitute parts that maintain functional compatibility for existing designs or new applications requiring similar performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL5293CSZ is determined by strict alignment of the following critical parameters:

Functional Compatibility Criteria:

• Amplifier Type: Current Feedback (all substitutes must be current feedback amplifiers)
• Number of Circuits: 2 (dual-channel configuration)
• Package / Case: 8-SOIC surface mount form factor
• Mounting Type: Surface Mount

Electrical Performance Boundaries:

• Voltage Supply Span: Substitute minimum supply voltage must not exceed the EL5293CSZ minimum (5 V), and substitute maximum supply voltage must accommodate the EL5293CSZ maximum (10 V)
• Operating Temperature Range: Substitute must cover or exceed the EL5293CSZ range (-40°C ~ 85°C)
• Current Output per Channel: Substitute must provide sufficient output current (EL5293CSZ: 120 mA)

Compliance Requirements:

• RoHS3 Compliance: All substitutes must maintain ROHS3 compliance status
• REACH Status: All substitutes must maintain REACH Unaffected status

The three identified substitute parts (AD8002ARZ, AD8002ARZ-R7, and LT1396CS8#TRPBF) satisfy these criteria with variations in slew rate, bandwidth, and supply current that remain within acceptable operational parameters for current feedback amplifier applications.

Parameter Comparison

Engineering Selection Recommendations

AD8002ARZ and AD8002ARZ-R7 (Analog Devices Inc.)

Both AD8002ARZ variants are active products with identical electrical specifications. The primary distinction is packaging: AD8002ARZ is supplied in Tube packaging, while AD8002ARZ-R7 is supplied in Tape & Reel (TR) format. Both devices maintain ROHS3 compliance and REACH Unaffected status, with improved moisture sensitivity (MSL 1, Unlimited) compared to the EL5293CSZ.

The AD8002 series exhibits higher bandwidth (600 MHz versus 300 MHz) and lower output current per channel (70 mA versus 120 mA). The minimum supply voltage requirement increases to 6 V, which must be verified against circuit design specifications. Supply current increases to 10 mA per channel pair. These devices are suitable for applications where the EL5293CSZ's higher slew rate is not critical and where the increased bandwidth provides design flexibility.

LT1396CS8#TRPBF (Analog Devices Inc., LT® Series)

The LT1396CS8#TRPBF is an active product supplied in Tape & Reel format with ROHS3 compliance and REACH Unaffected status. This device features the lowest slew rate (800V/µs) and moderate bandwidth (400 MHz) among the substitutes. The operating temperature range is restricted to 0°C ~ 70°C, which does not cover the full -40°C ~ 85°C range of the EL5293CSZ. This limitation requires verification for applications requiring extended temperature operation.

The LT1396 maintains supply current comparable to the EL5293CSZ (4.6 mA versus 4 mA) and provides lower output current per channel (80 mA versus 120 mA). The minimum supply voltage is 4 V, providing greater flexibility for lower-voltage applications. Moisture sensitivity is improved to MSL 1 (Unlimited).

Compliance and Availability

All three substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the EL5293CSZ. All substitutes are active products with confirmed inventory availability, eliminating obsolescence risk associated with the EL5293CSZ.

Frequently Asked Questions (FAQ)

Q: Can the AD8002ARZ and AD8002ARZ-R7 be used interchangeably with the EL5293CSZ?

A: Both AD8002 variants are electrically identical and functionally compatible with the EL5293CSZ in the same 8-SOIC package. The difference between AD8002ARZ (Tube) and AD8002ARZ-R7 (Tape & Reel) is packaging format only. Selection depends on assembly process requirements. However, the minimum supply voltage increases from 5 V to 6 V, and output current per channel decreases from 120 mA to 70 mA. Circuit designs must accommodate these parameter differences.

Q: What is the primary limitation of the LT1396CS8#TRPBF as a substitute?

A: The LT1396CS8#TRPBF operating temperature range is 0°C ~ 70°C, which does not extend to the -40°C minimum of the EL5293CSZ. Applications requiring operation below 0°C or above 70°C cannot use this substitute. Additionally, output current per channel is 80 mA compared to the EL5293CSZ specification of 120 mA.

Q: Are all substitute parts in the same physical package?

A: All substitute parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package, which is physically identical to the EL5293CSZ. PCB layout and footprint compatibility are maintained across all substitutes.

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

A: The EL5293CSZ has MSL 3 (168 Hours), requiring controlled moisture exposure during storage and handling. All substitute parts have MSL 1 (Unlimited), eliminating moisture sensitivity constraints. This simplifies inventory management and reduces handling requirements for substitute parts.

Q: How do the bandwidth and slew rate differences affect circuit performance?

A: The EL5293CSZ provides 2200V/µs slew rate and 300 MHz bandwidth. The AD8002 series offers higher bandwidth (600 MHz) but lower slew rate (1200V/µs). The LT1396 provides moderate bandwidth (400 MHz) and lower slew rate (800V/µs). Applications sensitive to slew rate performance may require circuit redesign with the AD8002 or LT1396. Applications benefiting from higher bandwidth may perform better with the AD8002 series.

Q: What supply voltage considerations apply to substitution?

A: The EL5293CSZ operates with 5 V to 10 V supply span. The AD8002 series requires 6 V minimum, eliminating 5 V single-supply operation. The LT1396 operates from 4 V minimum, providing greater flexibility for lower-voltage designs. All substitutes support the 10 V maximum. Circuit power supply specifications must be verified against substitute minimum voltage requirements.

Q: Are there differences in input bias current between the EL5293CSZ and substitutes?

A: The EL5293CSZ specifies 1 µA input bias current. The AD8002 series specifies 5 µA, and the LT1396 specifies 10 µA. Applications with high-impedance input sources or precision transimpedance configurations may require input bias current compensation adjustments when substituting.
