EL5257IS-T13 Equivalent & Substitute Parts

Part Overview

The EL5257IS-T13 is a voltage feedback amplifier integrated circuit manufactured by Renesas Electronics Corporation, configured as a dual-channel (2 circuit) device in an 8-SOIC surface mount package. This component is classified as obsolete, indicating that direct procurement from the original manufacturer is no longer available through standard distribution channels. The identification of equivalent and substitute parts is necessary to maintain design continuity, support legacy system repairs, and enable production of boards utilizing this amplifier topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL5257IS-T13 is determined by the following critical parameters that must align with the original design requirements:

Primary Compatibility Criteria:

• Amplifier Type: Voltage Feedback (required)
• Number of Circuits: 2 (dual-channel configuration)
• Package / Case: 8-SOIC surface mount form factor
• Voltage Supply Range: Minimum 5V to Maximum 12V overlap
• Operating Temperature Range: Minimum -40°C to Maximum 85°C overlap
• Mounting Type: Surface Mount

Secondary Performance Parameters:

• Slew Rate: 700 V/µs (baseline performance metric)
• Gain Bandwidth Product: 210 MHz (frequency response characteristic)
• -3dB Bandwidth: 600 MHz (frequency response characteristic)
• Current - Input Bias: 200 nA (input impedance characteristic)
• Voltage - Input Offset: 500 µV (DC accuracy characteristic)
• Current - Supply: 6 mA per 2 channels (power consumption)
• Current - Output / Channel: 140 mA (output drive capability)

The substitute parts identified below maintain the core functional topology (dual-channel voltage feedback amplifier in 8-SOIC package) while presenting variations in performance specifications and compliance status. These variations must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

LMH6622MA/NOPB (Texas Instruments)

This substitute is suitable for applications where reduced slew rate (85 V/µs versus 700 V/µs) is acceptable and lower bandwidth performance (-3dB Bandwidth: 160 MHz versus 600 MHz) meets design specifications. The LMH6622MA/NOPB offers ROHS3 compliance and active product status, ensuring long-term availability. Input bias current is significantly higher (4.7 µA versus 200 nA), which may impact high-impedance input circuits. Output current per channel is reduced (90 mA versus 140 mA). This device is packaged in Tube format and maintains the 8-SOIC form factor with identical supply voltage range (-40°C to 85°C operating temperature).

LT1816CS8#TRPBF (Analog Devices Inc.)

This substitute provides superior slew rate performance (1500 V/µs versus 700 V/µs) and higher -3dB bandwidth (350 MHz versus 600 MHz), making it suitable for higher-frequency applications. The LT1816CS8#TRPBF achieves ROHS3 compliance and maintains active product status. Input bias current (2 µA) and input offset voltage (200 µV) are improved relative to the main part. Supply voltage range extends to lower minimum (2.5 V versus 5 V), though maximum operating temperature is reduced to 70°C (versus 85°C). Output current per channel is lower (80 mA versus 140 mA). This device is packaged in Tape & Reel format and maintains the 8-SOIC form factor.

Compliance and Availability Considerations

Both substitute parts are classified as Active products with ROHS3 compliance, providing regulatory alignment for new designs and long-term procurement stability. The original EL5257IS-T13 is obsolete and RoHS non-compliant, necessitating substitution for applications requiring current regulatory compliance or extended component availability.

Frequently Asked Questions (FAQ)

Q: Can the LMH6622MA/NOPB directly replace the EL5257IS-T13 in all applications?

A: The LMH6622MA/NOPB maintains the same package form factor (8-SOIC) and dual-channel voltage feedback topology. However, performance differences exist: slew rate is reduced to 85 V/µs (from 700 V/µs), -3dB bandwidth is reduced to 160 MHz (from 600 MHz), and input bias current increases to 4.7 µA (from 200 nA). Substitution is valid only when application specifications accommodate these performance reductions.

Q: What are the key differences between the LT1816CS8#TRPBF and the EL5257IS-T13?

A: The LT1816CS8#TRPBF offers higher slew rate (1500 V/µs versus 700 V/µs) and improved input characteristics (2 µA bias current versus 200 nA, 200 µV offset versus 500 µV). The -3dB bandwidth is 350 MHz (versus 600 MHz). Operating temperature maximum is reduced to 70°C (versus 85°C), and output current per channel is lower at 80 mA (versus 140 mA). These differences must be evaluated against specific circuit requirements.

Q: Are both substitute parts available in the same packaging format?

A: Both substitute parts are available in 8-SOIC surface mount packages, maintaining mechanical compatibility with the original EL5257IS-T13. The LMH6622MA/NOPB is supplied in Tube packaging, while the LT1816CS8#TRPBF is supplied in Tape & Reel format. These packaging differences affect handling and assembly processes but do not impact electrical compatibility.

Q: What is the significance of the RoHS compliance difference?

A: The EL5257IS-T13 is RoHS non-compliant, while both substitute parts (LMH6622MA/NOPB and LT1816CS8#TRPBF) are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, substitution with either active part is necessary. RoHS compliance affects material composition and environmental impact but does not alter electrical performance.

Q: How do supply voltage ranges compare across these three parts?

A: The EL5257IS-T13 operates from 5V to 12V. The LMH6622MA/NOPB maintains identical supply range (5V to 12V). The LT1816CS8#TRPBF extends the minimum supply voltage to 2.5V but reduces the maximum to 11V. For applications requiring 5V to 12V operation, all three parts are compatible. For applications requiring lower supply voltages (below 5V), only the LT1816CS8#TRPBF is suitable.

Q: What impact do input bias current differences have on circuit design?

A: The EL5257IS-T13 specifies 200 nA input bias current, the LMH6622MA/NOPB specifies 4.7 µA, and the LT1816CS8#TRPBF specifies 2 µA. Higher input bias current increases input offset voltage errors in high-impedance circuits and may require input bias current compensation networks. For low-impedance input circuits (below 10 kΩ), these differences have minimal impact. For high-impedance input circuits (above 100 kΩ), the original EL5257IS-T13 specification is superior.

Q: Can these parts be used interchangeably in existing PCB designs?

A: All three parts share the 8-SOIC surface mount package with identical pin spacing and footprint dimensions (0.154" width, 3.90mm). PCB layout compatibility is maintained. However, electrical performance differences require circuit analysis to confirm that application specifications are met by the substitute part. Pin-to-pin compatibility does not guarantee functional equivalence.

Q: What is the product status significance for long-term supply?

A: The EL5257IS-T13 is classified as Obsolete, indicating that the manufacturer has discontinued production and distribution. The LMH6622MA/NOPB and LT1816CS8#TRPBF are both classified as Active, meaning the manufacturers continue production and support. For applications requiring component availability beyond current inventory, substitution with an Active product is necessary.
