Key Parameters

Substitute Part Grouping Explanation

The MAX4473EUA+ qualifies as a direct substitute based on the following critical parameters:

• RF Type: Both parts are GSM RF controllers
• Package / Case: Identical 8-TSSOP/8-MSOP (0.118", 3.00mm Width) package
• Supplier Device Package: Both use 8-uMAX/uSOP configuration
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)
• REACH Status: Both REACH Unaffected
• ECCN Classification: Both classified as EAR99
• HTSUS Code: Both use 8542.33.0001

The primary distinction is product status and RoHS compliance. The MAX4473EUA+ is active production and ROHS3 compliant, whereas the MAX4473EUA is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The MAX4473EUA+ is the direct active equivalent for the obsolete MAX4473EUA. Selection criteria are based on the following factors:

For New Designs and Production: The MAX4473EUA+ is the appropriate choice. It maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance, aligning with current regulatory requirements and supply chain continuity.

For Legacy System Maintenance: The MAX4473EUA remains available in inventory (10156 units) for applications requiring the original non-compliant variant. However, transition to MAX4473EUA+ is recommended for long-term sustainability.

Compliance Considerations: The MAX4473EUA+ meets ROHS3 requirements, whereas the MAX4473EUA does not. Organizations subject to RoHS directives must use the MAX4473EUA+ for compliant designs.

Package Compatibility: Both parts use identical 8-TSSOP/8-MSOP packages with 0.118" width and 8-uMAX/uSOP supplier configuration, ensuring direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAX4473EUA+ be used as a direct replacement for MAX4473EUA in existing designs?

A: Yes. Both parts share identical RF type (GSM), package configuration (8-TSSOP/8-MSOP), and electrical classification. PCB layouts and footprints are directly compatible. The primary difference is product status and RoHS compliance.

Q: What is the significance of the "+" designation in MAX4473EUA+?

A: The "+" suffix indicates an updated variant with ROHS3 compliance and active production status. The core functionality and package remain unchanged from the base MAX4473EUA.

Q: Are there packaging differences between these parts?

A: Yes. The MAX4473EUA is supplied in bulk packaging, while MAX4473EUA+ is supplied in tube packaging. This affects handling and storage but does not impact electrical or mechanical compatibility.

Q: Which part should be specified for new GSM RF power controller designs?

A: The MAX4473EUA+ should be specified for new designs. It provides active product support, regulatory compliance, and assured long-term availability.

Q: Is the MSL rating identical for both parts?

A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Do both parts have the same REACH and ECCN classifications?

A: Yes. Both parts are REACH Unaffected and classified as EAR99, with identical HTSUS code 8542.33.0001.
