MAX4461TESA-T Equivalent & Substitute Parts

Part Overview

The MAX4461TESA-T is an instrumentation amplifier manufactured by Analog Devices Inc./Maxim Integrated, designed for precision signal conditioning applications requiring rail-to-rail output capability. This linear amplifier integrates one circuit in an 8-SOIC surface mount package and operates across a supply voltage range of 2.85 V to 5.25 V.

The MAX4461TESA-T carries an Obsolete product status. Locating equivalent or substitute components becomes necessary when procurement from original inventory becomes unavailable or when design flexibility permits the use of active alternatives with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX4461TESA+T serves as a direct substitute for the MAX4461TESA-T based on complete electrical and mechanical parameter equivalence. All functional specifications, package dimensions, and compliance certifications are identical between the two part numbers.

The primary distinction is product status: MAX4461TESA-T is classified as Obsolete, while MAX4461TESA+T maintains Active status. This status difference reflects manufacturing and supply chain availability rather than technical capability or performance characteristics.

Both parts are ROHS3 Compliant and carry identical Moisture Sensitivity Level (MSL) ratings, confirming equivalent handling and storage requirements. The substitution is valid for all applications where the MAX4461TESA-T was originally specified, provided that the design does not depend on obsolete component characteristics or legacy supply chain documentation.

Frequently Asked Questions (FAQ)

Q: Can MAX4461TESA+T replace MAX4461TESA-T in existing designs?

A: Yes. All electrical parameters, mechanical specifications, and compliance certifications are identical. Direct substitution is valid without circuit modification or re-qualification.

Q: What is the difference between MAX4461TESA-T and MAX4461TESA+T?
