EL5166IS-T7 Equivalent & Substitute Parts

Part Overview

The EL5166IS-T7 is a Current Feedback Amplifier manufactured by Renesas Electronics Corporation, housed in an 8-SOIC surface mount package. This device delivers a slew rate of 6000V/µs and -3dB bandwidth of 1.4 GHz, designed for high-speed signal conditioning applications. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility. Substitute parts must preserve the 8-SOIC package format, current feedback topology, and operating temperature range of -40°C to 85°C.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

AD8009ARZ-REEL7 and AD8009ARZ-REEL are the closest electrical equivalents to the EL5166IS-T7. Both devices deliver 5500V/µs slew rate and 1 GHz bandwidth, approaching the original part's 6000V/µs and 1.4 GHz specifications. These parts are manufactured by Analog Devices Inc., carry active product status, and comply with ROHS3 standards with MSL 1 rating. The AD8009 series provides 175 mA output current per channel, which is lower than the EL5166IS-T7's 200 mA but remains suitable for most applications within the 5V to 12V supply range.

Secondary Substitutes (Reduced Performance):

AD8007ARZ, AD8007ARZ-R7, and AD8007ARZ-RL offer 1000V/µs slew rate and 650 MHz bandwidth. These parts are appropriate for applications where the original bandwidth and slew rate specifications exceed system requirements. The AD8007 series maintains 130 mA output current capability and operates across the full 5V to 12V supply span.

Lower Performance Alternatives:

AD8001ARZ, AD8001ARZ-REEL, and AD8001ARZ-REEL7 deliver 1200V/µs slew rate and 715 MHz bandwidth with reduced supply current of 5 mA. These parts are suitable only for applications with significantly relaxed bandwidth and slew rate requirements. The minimum supply voltage for AD8001 variants is 6V, which restricts use in 5V-only systems.

AD8011ARZ provides the lowest power consumption at 1.3 mA supply current and operates from 3V minimum, but delivers only 3500V/µs slew rate and 400 MHz bandwidth. This part is appropriate for battery-powered or low-voltage applications where performance trade-offs are acceptable.

Compliance Advantage:

All Analog Devices substitute parts listed above are active products with ROHS3 compliance and MSL 1 rating, providing superior environmental and supply chain reliability compared to the obsolete, RoHS non-compliant EL5166IS-T7.

Frequently Asked Questions (FAQ)

Q: Can AD8009ARZ-REEL7 directly replace EL5166IS-T7 in existing designs?

A: AD8009ARZ-REEL7 is mechanically and electrically compatible with EL5166IS-T7. Both use 8-SOIC packaging and operate across -40°C to 85°C. The AD8009 delivers 5500V/µs slew rate versus the original 6000V/µs, and 1 GHz bandwidth versus 1.4 GHz. Output current is 175 mA per channel versus 200 mA. These differences are within acceptable margins for most high-speed signal conditioning applications. Pin-for-pin compatibility is maintained.

Q: What is the minimum supply voltage requirement for each substitute?

A: AD8001 variants require minimum 6V supply, restricting use in 5V-only systems. AD8007, AD8009, and EL5166IS-T7 all support 5V minimum. AD8011ARZ operates from 3V minimum, enabling use in lower-voltage applications. Maximum supply voltage is 12V across all parts.

Q: How do packaging options affect substitution?

A: All substitute parts are available in 8-SOIC surface mount package matching the original EL5166IS-T7. Packaging variants (Tube, Tape & Reel, Cut Tape & Digi-Reel) do not affect electrical performance or pin compatibility. Selection depends on procurement and assembly requirements. Tape & Reel variants (REEL, REEL7, R7, RL suffixes) are preferred for automated assembly processes.

Q: Which substitute offers the best compliance profile?

A: All Analog Devices substitutes (AD8001, AD8007, AD8009, AD8011 series) are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity). The original EL5166IS-T7 is RoHS non-compliant with MSL 3 (168-hour limit). For new designs or compliance-critical applications, any of the Analog Devices alternatives provide superior environmental and reliability credentials.

Q: What is the trade-off between slew rate and bandwidth when selecting a substitute?

A: Higher slew rate and bandwidth enable faster signal transitions and higher-frequency operation. EL5166IS-T7 specifies 6000V/µs and 1.4 GHz. AD8009 series provides 5500V/µs and 1 GHz, suitable for most applications. AD8007 series delivers 1000V/µs and 650 MHz, appropriate for reduced-bandwidth requirements. AD8001 series offers 1200V/µs and 715 MHz with lower power consumption. AD8011 provides 3500V/µs and 400 MHz for low-power applications. Selection depends on actual system bandwidth and slew rate requirements.

Q: Are there supply current differences between substitutes?

A: Yes. EL5166IS-T7 draws 8.5 mA. AD8009 series draws 16 mA (higher). AD8007 series draws 9 mA (comparable). AD8001 series draws 5 mA (lower). AD8011 draws 1.3 mA (significantly lower). Power-sensitive applications should prioritize AD8001 or AD8011. High-performance applications can tolerate AD8009's increased current draw.

Q: Is input offset voltage a critical selection parameter?

A: EL5166IS-T7 specifies 500 µV input offset. AD8007 and AD8007ARZ-R7 match this specification at 500 µV. AD8001, AD8009, and AD8011 variants specify 2 mV offset. For precision DC-coupled applications, AD8007 variants are preferred. For AC-coupled or less stringent applications, the higher offset of other variants is acceptable.

Q: What is the significance of input bias current differences?

A: EL5166IS-T7 specifies 8.5 µA input bias. AD8007 specifies 4 µA (lower). AD8001 and AD8011 specify 5 µA (lower). AD8009 specifies 50 µA (higher). Lower bias current reduces input impedance loading effects. AD8009's higher bias current may require input impedance compensation in sensitive applications. For most applications, differences are negligible.
