Procurement Notes

Verify the specific package marking and manufacturer lot codes against official Richtek documentation before integration. Confirm RoHS compliance status through current datasheets. Ensure the supplier provides valid traceability records. Cross-reference the part number suffix with the manufacturer's latest revision history to avoid obsolete variants.

Selection Notes

Select this component when designing USB Type-C interfaces requiring integrated CC and SBU fault protection. It is suitable for applications needing compact WL-CSP packaging. Verify that the operating temperature range meets system environmental requirements. Ensure compatibility with upstream protocol controllers regarding signal levels.

Part Context

This component belongs to Richtek's USB Type-C protection and control portfolio. It complements programmable PD controllers like the RT1715 series by handling physical layer faults. The product line targets modern mobile and computing devices requiring robust USB-C connectivity.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in verified sources. Evaluate alternative USB-C protection switches from other manufacturers only if they match the WL-CSP-8B footprint and electrical specifications exactly.
