Engineering Selection Recommendations

Direct Replacement:

EL5263ISZ is the direct equivalent to EL5263IS. Both devices share identical electrical performance specifications and package configuration. EL5263ISZ is preferred for new designs and production continuity due to ROHS3 compliance status, whereas the original EL5263IS carries RoHS non-compliant designation. Both parts are classified as obsolete, indicating limited future availability.

Active Product Alternatives:

For applications requiring active product status with long-term supply assurance, the following Analog Devices current feedback amplifiers are suitable based on application requirements:

AD8008ARZ / AD8008ARZ-REEL / AD8008ARZ-REEL7: These devices maintain the 500 MHz bandwidth specification of the EL5263IS with reduced slew rate (1000V/µs vs. 4000V/µs). Supply current is higher at 9 mA per channel, but output current capability is superior at 130 mA per channel. Input offset voltage is significantly lower at 500 µV. These parts are appropriate for applications where bandwidth and output current are critical and slew rate reduction is acceptable.

AD8012ARZ / AD8012ARZ-REEL / AD8012ARZ-REEL7: These devices provide intermediate slew rate performance at 2250V/µs with reduced bandwidth of 350 MHz. Supply current is comparable at 1.7 mA per channel with output current of 125 mA. Minimum supply voltage extends to 3V, providing broader supply range compatibility. These parts are suitable for applications with moderate bandwidth requirements and lower supply voltage operation.

AD8002ARZ / AD8002ARZ-R7: These devices deliver the highest bandwidth at 600 MHz with reduced slew rate of 1200V/µs. Supply current is elevated at 10 mA per channel with reduced output current of 70 mA. Minimum supply voltage is 6V. These parts are appropriate for bandwidth-critical applications where higher supply current is acceptable.

AD8072JRZ: This device is classified as Last Time Buy status. It provides significantly reduced bandwidth at 100 MHz and slew rate of 500V/µs with the lowest supply current at 3.5 mA. Output current is limited to 30 mA. This part is suitable only for low-frequency applications and should not be selected for new designs due to end-of-life status.

All Analog Devices alternatives carry ROHS3 compliance and active product status, ensuring long-term availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can EL5263ISZ be used as a direct replacement for EL5263IS?

A: Yes. EL5263ISZ is electrically and mechanically identical to EL5263IS. Both devices are dual-channel current feedback amplifiers in 8-SOIC packages with identical performance specifications. The primary difference is packaging format and RoHS compliance status. EL5263ISZ is preferred due to ROHS3 compliance.

Q: What is the primary reason to select an Analog Devices alternative over EL5263ISZ?

A: Analog Devices alternatives (AD8002ARZ, AD8008ARZ, AD8012ARZ, AD8072JRZ) carry active product status, ensuring long-term supply availability and production support. Both EL5263IS and EL5263ISZ are obsolete, indicating limited future inventory and potential discontinuation. Active products provide supply chain security for ongoing production requirements.

Q: Are all substitute parts compatible with the same PCB layout as EL5263IS?

A: All substitute parts listed share the 8-SOIC package configuration with identical pin spacing (0.154" width, 3.90mm). PCB footprints are mechanically compatible. However, electrical performance differences require circuit design verification, particularly regarding slew rate, bandwidth, supply current, and output current specifications.

Q: Which substitute part most closely matches the EL5263IS performance?

A: AD8008ARZ, AD8008ARZ-REEL, and AD8008ARZ-REEL7 maintain the 500 MHz bandwidth specification of the EL5263IS. These devices provide superior input offset voltage performance at 500 µV and higher output current capability at 130 mA per channel. Slew rate is reduced to 1000V/µs, and supply current is increased to 9 mA per channel.

Q: What are the key parameter differences between EL5263IS and AD8012ARZ?

A: AD8012ARZ exhibits reduced slew rate (2250V/µs vs. 4000V/µs) and reduced bandwidth (350 MHz vs. 500 MHz). Supply current is comparable at 1.7 mA per channel. Output current is slightly higher at 125 mA. Minimum supply voltage extends to 3V, providing broader supply range. These differences require circuit design evaluation for specific application requirements.

Q: Is AD8072JRZ suitable as a replacement for EL5263IS?

A: AD8072JRZ is not recommended as a replacement for EL5263IS. This device provides significantly reduced bandwidth (100 MHz vs. 500 MHz) and slew rate (500V/µs vs. 4000V/µs), making it unsuitable for high-speed applications. Additionally, AD8072JRZ carries Last Time Buy status, indicating end-of-life designation and limited future availability.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Tube (standard packaging), Tape & Reel (TR) for automated assembly, and Cut Tape (CT) & Digi-Reel® for mixed-volume applications. All variants maintain identical electrical specifications and 8-SOIC package configuration. Selection depends on production volume and assembly process requirements.

Q: Are all substitute parts RoHS compliant?

A: EL5263ISZ and all Analog Devices alternatives (AD8002ARZ, AD8008ARZ, AD8012ARZ, AD8072JRZ) carry ROHS3 compliance status. The original EL5263IS is RoHS non-compliant. For applications requiring regulatory compliance, EL5263ISZ or Analog Devices alternatives must be selected.

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts operate across the temperature range of -40°C to 85°C, matching the EL5263IS specification. This range is suitable for industrial and commercial applications within standard operating environments.
