MAX4473EUA-T Equivalent & Substitute Parts

Part Overview

The MAX4473EUA-T is an RF Power Controller IC designed for GSM applications, housed in an 8-TSSOP/8-MSOP package. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing system support and new design implementations. The obsolete status necessitates sourcing from alternative inventory channels or identifying functionally equivalent active components to maintain supply chain continuity.

Substitute Part Grouping Explanation

Substitution for the MAX4473EUA-T is determined by strict alignment of the following electrical and mechanical parameters:

• RF Application Type: GSM-specific power control functionality
• Package Configuration: 8-TSSOP/8-MSOP form factor with 0.118" width (3.00mm)
• Supplier Device Package: 8-uMAX/uSOP designation
• Base Product Series: MAX447 family
• Regulatory Compliance: ROHS3 compliance and EAR99 classification
• Moisture Sensitivity: MSL Level 1

The substitute part MAX4473EUA+T maintains identical electrical specifications, package geometry, and regulatory certifications while offering active product status and improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The MAX4473EUA+T serves as a direct functional equivalent to the MAX4473EUA-T. Both components share identical electrical specifications, package geometry, and regulatory compliance certifications. The primary distinction is product lifecycle status: the MAX4473EUA-T is obsolete while the MAX4473EUA+T maintains active status with significantly higher inventory availability (69,200 units versus 16,050 units).

For new designs and ongoing production requirements, the MAX4473EUA+T is the appropriate selection. The packaging format difference (Tape & Reel versus Tube) reflects standard industry practice for active components and does not affect electrical or mechanical compatibility. Both components maintain ROHS3 compliance and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Are MAX4473EUA-T and MAX4473EUA+T electrically identical?

A: Yes. Both components are GSM RF Power Controller ICs with identical electrical specifications, RF type classification, and functional performance within the MAX447 product family.

Q: What is the significance of the packaging format difference?

A: The main part uses Tube packaging while the substitute uses Tape & Reel (TR) format. This reflects standard industry practice for obsolete versus active components and does not affect pin configuration, electrical performance, or PCB assembly compatibility.

Q: Can MAX4473EUA+T be used as a direct replacement in existing assemblies?

A: Yes. The 8-TSSOP/8-MSOP package geometry, pin count, and electrical specifications are identical, enabling direct substitution in PCB designs and manufacturing processes.

Q: Are there any regulatory or compliance differences?

A: No. Both components maintain ROHS3 compliance, EAR99 export classification, and MSL Level 1 moisture sensitivity rating.

Q: Why is the MAX4473EUA-T listed as obsolete?

A: Product obsolescence reflects manufacturer lifecycle decisions. The MAX4473EUA+T represents the active equivalent within the same product family and is the recommended source for current and future applications.
