Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL8173FSZ is based on compatibility across the following critical parameters:

Package Compatibility: Both the main part and substitute must utilize the 8-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm Width) to ensure direct PCB footprint compatibility without layout modifications.

Electrical Operating Range: The substitute must support the required supply voltage span and operating temperature range. The EL8173FSZ operates from 2.4V to 5.5V across -40°C to 125°C; substitute parts must encompass or exceed these specifications.

Output Configuration: Rail-to-rail output capability is a fundamental requirement for the EL8173FSZ. Substitute parts must maintain this output type to preserve signal swing characteristics in the application circuit.

Single Circuit Configuration: The EL8173FSZ contains one amplifier circuit. Substitute parts must match this circuit count to maintain functional equivalence.

Compliance Standards: All substitute parts must maintain ROHS3 compliance and REACH unaffected status to satisfy regulatory requirements for the original part.

The LTC6240HS8#PBF from Analog Devices Inc. satisfies these substitution criteria through matching package geometry, expanded electrical operating range, and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The EL8173FSZ is classified as obsolete, making the LTC6240HS8#PBF the identified substitute for design continuity and production support. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

The LTC6240HS8#PBF is an active product from Analog Devices Inc., ensuring long-term availability and supply chain stability compared to the obsolete EL8173FSZ. Both devices share identical package geometry (8-SOIC), operating temperature range (-40°C to 125°C), and rail-to-rail output configuration, enabling direct substitution without PCB layout modifications.

The LTC6240HS8#PBF demonstrates superior electrical performance characteristics across multiple parameters: slew rate of 10 V/µs versus 0.55 V/µs, input bias current of 0.2 pA versus 700 pA, and input offset voltage of 50 µV versus 200 µV. The substitute part operates across an expanded supply voltage range (2.8V to 6V) that encompasses the EL8173FSZ specification (2.4V to 5.5V). The LTC6240HS8#PBF features improved moisture sensitivity classification (MSL 1 versus MSL 3), reducing handling and storage constraints.

Frequently Asked Questions (FAQ)

Q: Can the LTC6240HS8#PBF directly replace the EL8173FSZ without PCB modifications?

A: Yes. Both devices utilize identical 8-SOIC package geometry with 0.154" (3.90mm) width, enabling direct footprint compatibility. No PCB layout changes are required for physical substitution.

Q: What are the key electrical differences between these parts?

A: The LTC6240HS8#PBF provides superior performance in slew rate (10 V/µs versus 0.55 V/µs), input bias current (0.2 pA versus 700 pA), and input offset voltage (50 µV versus 200 µV). Both parts maintain rail-to-rail output and single circuit configuration. The LTC6240HS8#PBF operates across a wider supply voltage range (2.8V to 6V versus 2.4V to 5.5V).

Q: Are there supply voltage compatibility concerns?

A: The LTC6240HS8#PBF minimum supply voltage is 2.8V, which is 0.4V higher than the EL8173FSZ minimum of 2.4V. Applications requiring operation below 2.8V require alternative substitutes. The maximum supply voltage of 6V on the LTC6240HS8#PBF exceeds the EL8173FSZ specification of 5.5V, providing additional headroom.

Q: What is the significance of the MSL rating difference?

A: The EL8173FSZ carries MSL 3 (168 hours), requiring controlled moisture exposure during storage and handling. The LTC6240HS8#PBF carries MSL 1 (unlimited), eliminating moisture sensitivity constraints and reducing handling complexity during manufacturing and assembly.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both the EL8173FSZ and LTC6240HS8#PBF are ROHS3 compliant and REACH unaffected, satisfying current regulatory standards for electronic component manufacturing and distribution.

Q: What is the amplifier type classification difference?

A: The EL8173FSZ is classified as an instrumentation amplifier, while the LTC6240HS8#PBF is classified as a general purpose amplifier. Both provide rail-to-rail output and single circuit configuration suitable for precision measurement and signal conditioning applications.

Q: Is the LTC6240HS8#PBF available in active production?

A: Yes. The LTC6240HS8#PBF is classified as active product status, ensuring ongoing availability and supply chain support. The EL8173FSZ is obsolete, making the LTC6240HS8#PBF the recommended substitute for new designs and production continuity.
