Engineering Selection Recommendations

The MAX4172EUA+T serves as the direct substitute for the obsolete MAX4172EUA-T. Both components share identical electrical specifications, mechanical packaging, and compliance certifications. The primary distinction is product status: the MAX4172EUA-T is classified as obsolete, while the MAX4172EUA+T maintains active product status from the manufacturer.

Selection of the MAX4172EUA+T is appropriate for new designs and ongoing production requiring current sense amplification. The substitute maintains full compatibility with existing circuit designs specified for the MAX4172EUA-T. Both parts are ROHS3 compliant and carry identical moisture sensitivity ratings, ensuring equivalent environmental performance and regulatory compliance.

The MAX4172EUA+T is available in higher inventory quantities (10,300 pieces) compared to the obsolete variant, supporting procurement continuity and supply chain stability. The packaging format remains identical: 8-TSSOP/8-MSOP surface mount configuration with 0.118" width specification.

Frequently Asked Questions (FAQ)

Q: Can the MAX4172EUA+T directly replace the MAX4172EUA-T in existing circuit designs?

A: Yes. The MAX4172EUA+T is electrically and mechanically identical to the MAX4172EUA-T across all specified parameters. No circuit modifications are required for substitution. Both components operate identically within the -40°C to 85°C temperature range and across the 3 V to 32 V supply voltage span.

Q: What is the difference between MAX4172EUA-T and MAX4172EUA+T?

A: The components are functionally equivalent. The primary difference is product status: MAX4172EUA-T is obsolete, while MAX4172EUA+T is active. The suffix designation reflects packaging format differences (tape and reel configuration for the +T variant), but electrical performance and pinout remain identical.

Q: Are both parts compatible with the same PCB layout and footprint?

A: Yes. Both the MAX4172EUA-T and MAX4172EUA+T use the identical 8-TSSOP/8-MSOP package with 0.118" (3.00mm) width. PCB footprints, land patterns, and assembly processes are interchangeable without modification.

Q: What compliance certifications apply to the substitute part?

A: The MAX4172EUA+T maintains ROHS3 compliance status and carries REACH unaffected classification, identical to the original part. Moisture sensitivity level is MSL 1 (Unlimited), indicating no special storage or handling requirements beyond standard component practices.

Q: Why is the MAX4172EUA-T classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this specific part number variant. The MAX4172EUA+T represents the active equivalent, ensuring continued availability and manufacturer support for current sense amplifier applications.

Q: Is the -3dB bandwidth specification identical between both parts?

A: Yes. Both the MAX4172EUA-T and MAX4172EUA+T specify -3dB bandwidth of 800 kHz. Input bias current, input offset voltage, supply current, and output current specifications are also identical across all measured parameters.
