EL5263IS-T13 Equivalent & Substitute Parts

Part Overview

The EL5263IS-T13 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. The high slew rate of 4000V/µs and 500 MHz bandwidth make it suitable for high-speed signal conditioning applications. Due to its obsolete status, identifying equivalent and substitute parts from active manufacturers is necessary for design continuity and procurement reliability.

Engineering Selection Recommendations

Primary Recommendation: AD8012ARZ or AD8012ARZ-REEL

The AD8012 series provides the closest functional match to the EL5263IS-T13. This device maintains the identical input offset voltage specification (1.5 mV), operates within the required temperature range (-40°C ~ 85°C), and supports the full 5V to 12V supply range. The slew rate of 2250V/µs and 350 MHz bandwidth represent a slight reduction from the original specification but remain suitable for most high-speed applications. The AD8012 series is actively produced by Analog Devices with ROHS3 compliance, ensuring long-term availability and regulatory compliance. Supply current is comparable at 1.7 mA per channel pair.

Secondary Recommendation: AD8008ARZ or AD8008ARZ-REEL

The AD8008 series offers superior output current capability (130 mA per channel versus 100 mA) and lower input offset voltage (500 µV). The -3dB bandwidth matches the original specification at 500 MHz. This device is actively produced with ROHS3 compliance. The minimum supply voltage requirement of 5V aligns with the original specification. Supply current is 9 mA per channel pair, which is higher than the original but acceptable for most applications.

Alternative Recommendation: AD8002ARZ or AD8002ARZ-R7

The AD8002 series provides the highest bandwidth (600 MHz) among available substitutes, exceeding the original 500 MHz specification. This device is actively produced with ROHS3 compliance. However, the minimum supply voltage requirement of 6V exceeds the original 5V minimum, and supply current is elevated at 10 mA per channel pair. Output current is reduced to 70 mA per channel. This option is suitable for applications where bandwidth enhancement is beneficial and the higher supply voltage is acceptable.

Not Recommended: AD8072JRZ

The AD8072 series has a product status of "Last Time Buy," indicating limited future availability. The -3dB bandwidth of 100 MHz and slew rate of 500V/µs represent significant performance reductions compared to the original specification. This device is suitable only for legacy applications with lower bandwidth requirements.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the EL5263IS-T13 with any of the recommended substitutes without PCB modifications?

A: Yes. All recommended substitutes use the identical 8-SOIC package with 0.154" (3.90mm) width, ensuring direct pin-compatible replacement on the PCB. No layout modifications are required.

Q: What is the primary reason the EL5263IS-T13 is obsolete?

A: The EL5263IS-T13 is classified as obsolete by Renesas Electronics Corporation, meaning it is no longer manufactured. Equivalent devices from active manufacturers such as Analog Devices provide superior product lifecycle support and regulatory compliance.

Q: Are all substitute parts RoHS compliant?

A: The recommended substitutes (AD8012, AD8008, and AD8002 series) are all ROHS3 compliant. The original EL5263IS-T13 is RoHS non-compliant. If RoHS compliance is required for your application, substitution is mandatory.

Q: What is the key difference between AD8012ARZ and AD8012ARZ-REEL?

A: Both devices are electrically identical. The primary difference is packaging format: AD8012ARZ is supplied in Tube packaging, while AD8012ARZ-REEL is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes. Select based on your procurement and assembly requirements.

Q: How does the slew rate difference between the EL5263IS-T13 (4000V/µs) and AD8012ARZ (2250V/µs) affect circuit performance?

A: Slew rate determines the maximum rate of voltage change the amplifier can produce. The AD8012 slew rate of 2250V/µs is lower than the original 4000V/µs. For most applications operating below 350 MHz bandwidth, this reduction is not limiting. Applications requiring the original 4000V/µs slew rate should consider the AD8008 series (1000V/µs) or AD8002 series (1200V/µs), though these also represent reductions from the original specification.

Q: What is the impact of the higher supply current in AD8002 and AD8008 compared to the original EL5263IS-T13?

A: The EL5263IS-T13 requires 1.5 mA per channel pair, while AD8002 requires 10 mA and AD8008 requires 9 mA. This represents a 6-7x increase in supply current. Verify that your power supply design can accommodate this increased current draw. The AD8012 series at 1.7 mA per channel pair provides the closest match to the original supply current specification.

Q: Can I use AD8072JRZ as a substitute?

A: The AD8072JRZ is not recommended as a primary substitute due to its "Last Time Buy" product status, indicating limited future availability. Additionally, the -3dB bandwidth of 100 MHz and slew rate of 500V/µs represent significant performance reductions. Use this device only for legacy applications with lower bandwidth requirements where long-term availability is not a concern.

Q: What supply voltage range must I verify before substitution?

A: The original EL5263IS-T13 operates from 5V to 12V. The AD8012 series maintains this range (3V to 12V, exceeding the original minimum). The AD8008 series also supports 5V to 12V. The AD8002 series requires a minimum of 6V, which exceeds the original 5V minimum. Verify your circuit's supply voltage before selecting a substitute.

Q: Are there any differences in input offset voltage that would affect circuit performance?

A: The EL5263IS-T13 specifies 1.5 mV input offset voltage. The AD8012 matches this specification exactly. The AD8008 offers superior performance at 500 µV. The AD8002 specifies 2 mV, which is slightly higher. For precision applications sensitive to input offset, the AD8008 provides the best performance. For general applications, all options are acceptable.
