EL5166IS Equivalent & Substitute Parts
Part Overview
The EL5166IS 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, supporting single-circuit amplification with 200 mA output current per channel. The EL5166IS is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. Substitute parts must maintain compatibility across electrical performance parameters, mechanical packaging, and thermal operating ranges.

Substitute Part Grouping Explanation
Substitution of the EL5166IS is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:
Critical Parameters for Substitution:
- Amplifier Type: Current Feedback (required match)
- Number of Circuits: 1 (required match)
- Package / Case: 8-SOIC (required match)
- Mounting Type: Surface Mount (required match)
- Operating Temperature Range: -40°C to 85°C (required match)
- Voltage Supply Span: 5V to 12V minimum (required compatibility)
Performance Parameters:
- Slew Rate: 6000V/µs (baseline specification)
- -3dB Bandwidth: 1.4 GHz (baseline specification)
- Current - Output / Channel: 200 mA (baseline specification)
Substitute parts are grouped into two categories:
Category 1: Direct Packaging Equivalent EL5166ISZ is an identical electrical specification variant differing only in packaging format (Tube vs. unspecified). This part maintains all electrical parameters and is the closest direct substitute.
Category 2: Functional Equivalents with Performance Variations AD8001ARZ, AD8001ARZ-REEL, AD8001ARZ-REEL7, AD8007ARZ, AD8007ARZ-R7, AD8007ARZ-RL, AD8009ARZ, AD8009ARZ-REEL, and AD8009ARZ-REEL7 are current feedback amplifiers in 8-SOIC packages with active product status. These parts operate within the same supply voltage range and temperature specifications but exhibit different slew rates, bandwidth, and output current characteristics. Selection depends on whether the application requires performance parameters matching or exceeding the EL5166IS baseline.

Engineering Selection Recommendations
Primary Recommendation: EL5166ISZ
EL5166ISZ is the direct electrical equivalent of EL5166IS with identical performance specifications across all parameters. The only difference is packaging format (Tube) and RoHS3 compliance status. This part is recommended for applications requiring exact performance matching and is available in active inventory (1928 units). Although classified as obsolete, EL5166ISZ provides the most direct substitution path with zero performance deviation.
Secondary Recommendations: AD8009 Series (AD8009ARZ, AD8009ARZ-REEL, AD8009ARZ-REEL7)
The AD8009 series from Analog Devices represents the closest active-status alternative. These parts deliver slew rate of 5500V/µs (95% of EL5166IS specification) and -3dB bandwidth of 1.0 GHz. Output current per channel is 175 mA, slightly below the 200 mA baseline. Supply current is elevated at 16 mA versus 8.5 mA. All AD8009 variants maintain 8-SOIC packaging, -40°C to 85°C operating range, and 5V to 12V supply compatibility. All variants carry ROHS3 compliance and active product status. High inventory availability (3400 to 15100 units) supports production continuity.
Tertiary Recommendations: AD8007 Series (AD8007ARZ, AD8007ARZ-R7, AD8007ARZ-RL)
AD8007 variants offer slew rate of 1000V/µs and -3dB bandwidth of 0.65 GHz, representing reduced performance relative to EL5166IS. Output current is 130 mA. These parts are suitable only for applications where bandwidth and slew rate requirements are less stringent than the original specification. All variants are ROHS3 compliant with active status.
Not Recommended: AD8001 Series (AD8001ARZ, AD8001ARZ-REEL, AD8001ARZ-REEL7)
AD8001 variants exhibit significantly reduced performance: slew rate of 1200V/µs (20% of EL5166IS) and -3dB bandwidth of 0.715 GHz (51% of EL5166IS). Output current is 70 mA (35% of baseline). Minimum supply voltage is 6V, incompatible with 5V-only applications. These parts are suitable only for low-frequency, low-speed applications and do not constitute viable substitutes for EL5166IS in high-performance signal conditioning circuits.
Frequently Asked Questions (FAQ)
Q: Can EL5166ISZ be used as a direct replacement for EL5166IS?
A: Yes. EL5166ISZ is electrically identical to EL5166IS across all performance parameters: 6000V/µs slew rate, 1.4 GHz bandwidth, 200 mA output current, and identical supply voltage range (5V to 12V). The only differences are packaging format and RoHS3 compliance status. Pin configuration and functional behavior are identical.
Q: What is the primary limitation of AD8001 series as a substitute?
A: AD8001 series exhibits 80% reduction in slew rate (1200V/µs vs. 6000V/µs) and 49% reduction in bandwidth (0.715 GHz vs. 1.4 GHz). Output current is limited to 70 mA versus 200 mA. These specifications make AD8001 unsuitable for high-speed, high-bandwidth applications. Additionally, minimum supply voltage is 6V, preventing use in 5V-only designs.
Q: How do AD8009 variants compare to the original EL5166IS?
A: AD8009 variants deliver 5500V/µs slew rate (92% of EL5166IS) and 1.0 GHz bandwidth (71% of EL5166IS). Output current is 175 mA (88% of baseline). Supply current increases to 16 mA from 8.5 mA. All variants maintain 8-SOIC packaging and -40°C to 85°C operating range. AD8009 is the recommended active-status alternative when EL5166ISZ is unavailable.
Q: Are all substitute parts available in 8-SOIC packaging?
A: Yes. All substitute parts listed are housed in 8-SOIC (0.154", 3.90mm Width) surface mount packages, ensuring mechanical and thermal compatibility with EL5166IS footprints.
Q: What is the difference between AD8009ARZ, AD8009ARZ-REEL, and AD8009ARZ-REEL7?
A: These three variants are electrically identical with identical performance specifications. The differences are packaging formats: AD8009ARZ is supplied in Tube, AD8009ARZ-REEL in standard Tape & Reel, and AD8009ARZ-REEL7 in Cut Tape & Digi-Reel format. Selection depends on assembly process requirements and quantity needs.
Q: Is RoHS compliance a factor in substitution?
A: EL5166IS is RoHS non-compliant, while all active-status substitutes (AD8001, AD8007, AD8009 series) are ROHS3 compliant. For applications subject to RoHS regulations, active-status substitutes are required. EL5166ISZ provides RoHS3 compliance while maintaining identical electrical performance.
Q: Can AD8007 series be used in place of EL5166IS?
A: AD8007 series is not recommended as a primary substitute due to significantly reduced performance: 1000V/µs slew rate (83% reduction) and 0.65 GHz bandwidth (54% reduction). Use AD8007 only in applications where bandwidth and slew rate requirements are substantially lower than the original EL5166IS specification.
Q: What inventory status should influence substitution decisions?
A: EL5166IS and EL5166ISZ are both classified as obsolete. For long-term production support, AD8009 series is recommended due to active product status and high inventory availability (3400 to 15100 units). AD8007 and AD8001 series also carry active status but with reduced performance characteristics.
