Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL8173IS-T13 is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 8-SOIC (0.154", 3.90mm Width) surface mount package to ensure mechanical and electrical compatibility with existing PCB layouts.

Output Configuration: Rail-to-rail output capability is required to maintain signal swing characteristics across the supply voltage range.

Single Circuit Configuration: The device must contain exactly one amplifier circuit per package.

Supply Voltage Range: Substitute parts must operate within or encompass the 2.4 V to 5.5 V supply span of the original device.

Operating Temperature Range: Substitute parts must support the -40°C to 125°C operating temperature range or a subset thereof that covers the application's thermal requirements.

Electrical Performance: Input offset voltage, input bias current, slew rate, and output current drive capability determine functional equivalence in signal conditioning applications.

The three substitute parts listed—MCP6021T-E/SN, LTC6240IS8#PBF, and LTC6240CS8#PBF—meet these core substitution criteria while offering enhanced performance characteristics in specific parameters.

Parameter Comparison

Engineering Selection Recommendations

MCP6021T-E/SN (Microchip Technology)

The MCP6021T-E/SN is an active product offering full compatibility with the EL8173IS-T13 across the complete operating temperature range (-40°C to 125°C). This device achieves ROHS3 compliance and provides improved slew rate performance (7 V/µs versus 0.55 V/µs). The MCP6021T-E/SN maintains the same 8-SOIC package footprint and supply voltage range (2.5 V to 5.5 V). Input offset voltage is higher at 500 µV compared to the original 200 µV specification. This substitute is suitable for applications where the extended temperature range and RoHS compliance are required.

LTC6240IS8#PBF (Analog Devices Inc.)

The LTC6240IS8#PBF is an active product supporting the -40°C to 85°C operating temperature range. This device provides superior electrical performance with input offset voltage of 50 µV and input bias current of 0.2 pA, both significantly better than the EL8173IS-T13. The slew rate is 10 V/µs. The supply voltage range is 2.8 V to 6 V. ROHS3 compliance is achieved. The LTC6240IS8#PBF is appropriate for applications operating within the -40°C to 85°C window where enhanced precision and faster response are beneficial.

LTC6240CS8#PBF (Analog Devices Inc.)

The LTC6240CS8#PBF is an active product with operating temperature range of 0°C to 70°C. This device shares identical electrical specifications with the LTC6240IS8#PBF, including 50 µV input offset voltage, 0.2 pA input bias current, and 10 V/µs slew rate. The supply voltage range is 2.8 V to 6 V. ROHS3 compliance is achieved. The LTC6240CS8#PBF is suitable for commercial temperature range applications where the narrower thermal window is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the MCP6021T-E/SN directly replace the EL8173IS-T13 in all applications?

A: The MCP6021T-E/SN is mechanically and electrically compatible with the EL8173IS-T13 in terms of package, pinout, and supply voltage range. However, the input offset voltage specification differs (500 µV versus 200 µV). Applications requiring the original 200 µV offset specification must evaluate whether the higher offset of the MCP6021T-E/SN is acceptable for the circuit design.

Q: What is the primary difference between the LTC6240IS8#PBF and LTC6240CS8#PBF?

A: The primary difference is the operating temperature range. The LTC6240IS8#PBF operates from -40°C to 85°C, while the LTC6240CS8#PBF operates from 0°C to 70°C. Both devices share identical electrical performance specifications. Selection depends on the thermal requirements of the target application.

Q: Are all substitute parts RoHS compliant?

A: The MCP6021T-E/SN, LTC6240IS8#PBF, and LTC6240CS8#PBF are all ROHS3 compliant. The original EL8173IS-T13 is RoHS non-compliant. If RoHS compliance is a design requirement, all three substitute parts satisfy this criterion.

Q: Do the substitute parts use the same package as the EL8173IS-T13?

A: Yes. All three substitute parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package, ensuring mechanical compatibility with existing PCB layouts designed for the EL8173IS-T13.

Q: Which substitute part offers the best overall performance?

A: The LTC6240IS8#PBF and LTC6240CS8#PBF both provide superior electrical performance with input offset voltage of 50 µV and slew rate of 10 V/µs. The LTC6240IS8#PBF extends the operating temperature range to -40°C to 85°C, making it suitable for wider thermal applications. The MCP6021T-E/SN supports the full -40°C to 125°C range but with higher input offset voltage.

Q: What is the supply voltage compatibility range across all parts?

A: The EL8173IS-T13 operates from 2.4 V to 5.5 V. The MCP6021T-E/SN operates from 2.5 V to 5.5 V. The LTC6240IS8#PBF and LTC6240CS8#PBF operate from 2.8 V to 6 V. Applications using supply voltages below 2.8 V must use either the EL8173IS-T13 or MCP6021T-E/SN.

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

A: Mechanical and package compatibility is confirmed across all parts. Electrical parameter differences, particularly in input offset voltage and slew rate, must be evaluated against circuit design specifications. Functional testing is required to confirm suitability for specific applications.
