Substitute Part Grouping Explanation

The FT221XQ-R has been identified as a manufacturer-recommended substitute for the SY100E445JZ. Substitution eligibility is determined by the following criteria:

Primary Substitution Criteria:

• Interface category classification (Interface)
• Data transport and signal bridging functionality
• Surface mount technology compatibility
• ROHS3 compliance certification
• REACH unaffected status
• Identical HTSUS classification (8542.39.0001)
• Identical ECCN classification (EAR99)

The FT221XQ-R operates as a USB bridge with SPI interface capability, providing modern USB 2.0 connectivity while maintaining the core data transport function of the original part. Both components share regulatory compliance frameworks and tariff classifications, supporting direct substitution in applications requiring interface functionality.

Engineering Selection Recommendations

The FT221XQ-R is the manufacturer-recommended substitute for the obsolete SY100E445JZ. Selection of this substitute is supported by:

• Product Status Alignment: The FT221XQ-R maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete SY100E445JZ.

• Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for equivalent component substitution.

• Tariff and Export Classification: Identical HTSUS (8542.39.0001) and ECCN (EAR99) classifications confirm regulatory equivalence for import, export, and procurement purposes.

• Interface Category: Both components are classified within the Interface category, maintaining functional equivalence for data transport applications.

• Packaging Consideration: The FT221XQ-R uses a 20-QFN package compared to the 28-PLCC of the original part. PCB layout redesign is required to accommodate the different package footprint and pin configuration.

Frequently Asked Questions (FAQ)

Q: Can the FT221XQ-R directly replace the SY100E445JZ without PCB modifications?

A: No. The FT221XQ-R uses a 20-QFN (4x4) package while the SY100E445JZ uses a 28-PLCC (11.48x11.48) package. PCB layout redesign is required, including footprint changes and signal routing adjustments.

Q: What are the key differences in interface functionality between these parts?

A: The SY100E445JZ provides Serial In/Parallel Out interface functionality. The FT221XQ-R provides USB to SPI bridge functionality with USB 2.0 protocol support. Application requirements determine functional compatibility.

Q: Are both components RoHS compliant?

A: Yes. Both the SY100E445JZ and FT221XQ-R are ROHS3 compliant and REACH unaffected, meeting environmental compliance requirements.

Q: What is the moisture sensitivity difference between these parts?

A: The SY100E445JZ has MSL 2 (1 Year) rating, while the FT221XQ-R has MSL 3 (168 Hours) rating. The FT221XQ-R requires more stringent moisture control during storage and handling.

Q: Is the FT221XQ-R suitable for applications requiring the original part's Serial In/Parallel Out interface?

A: The FT221XQ-R provides USB to SPI bridge functionality, which differs from the Serial In/Parallel Out interface of the SY100E445JZ. Application compatibility depends on specific interface requirements and system architecture.

Q: What supply voltage does the FT221XQ-R require?

A: The FT221XQ-R operates at 3.3V to 5V supply voltage with 11mA typical current consumption across the operating temperature range of -40°C to 85°C.
