Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WT32-E-AI5SC is determined by the following critical parameters:

• Integrated Circuit (IC): BlueCore5 architecture compatibility
• Mounting Type: Surface mount configuration
• Package Classification: Module form factor
• Moisture Sensitivity Level: MSL 3 (168 Hours) environmental rating
• Export Classification: ECCN 5A992C compliance
• Tariff Classification: HTSUS 8517.62.0090

The WT32I-E-AI61C qualifies as a substitute based on matching core IC architecture, identical mounting methodology, equivalent environmental specifications, and aligned regulatory classifications. The primary distinction lies in antenna configuration, where the substitute part specifies U.FL antenna interface with antenna not included, whereas the original part integrates antenna functionality.

Parameter Comparison

Engineering Selection Recommendations

Both the WT32-E-AI5SC and WT32I-E-AI61C share identical core specifications: BlueCore5 IC architecture, surface mount configuration, MSL 3 environmental rating, and matching export/tariff classifications. Both components carry obsolete product status.

The WT32I-E-AI61C provides RoHS compliance certification, whereas RoHS status is not specified for the original part. This distinction may be relevant for applications subject to RoHS regulatory requirements.

The primary design consideration is antenna interface: the WT32I-E-AI61C requires external antenna implementation via U.FL connector, while the WT32-E-AI5SC integrates antenna functionality. System redesign may be necessary if antenna configuration differs from the original design intent.

Frequently Asked Questions (FAQ)

Q: Can the WT32I-E-AI61C directly replace the WT32-E-AI5SC without design modification?

A: Direct replacement is possible only if the system design accommodates external U.FL antenna connection. The WT32-E-AI5SC integrates antenna functionality, while the WT32I-E-AI61C requires external antenna implementation. PCB layout and antenna design modifications may be required.

Q: Are both parts subject to the same environmental storage and handling requirements?

A: Yes. Both components specify MSL 3 (168 Hours), requiring identical moisture control and handling procedures during storage and assembly operations.

Q: What is the significance of the RoHS compliance designation on the WT32I-E-AI61C?

A: RoHS compliance indicates the component meets Restriction of Hazardous Substances regulations. This certification is relevant for applications or markets with RoHS mandates. The original WT32-E-AI5SC does not specify RoHS status.

Q: Are export restrictions identical for both parts?

A: Yes. Both components carry ECCN 5A992C classification and HTSUS 8517.62.0090 tariff code, indicating identical export control and customs treatment.

Q: Why are both components classified as obsolete?

A: Obsolete status indicates these components are no longer manufactured or supported by Silicon Labs. Procurement should prioritize available inventory, as future availability cannot be assured.
