Procurement Notes
Verify part status carefully as the EMI7403FCTBG is listed as obsolete or end-of-life by onsemi. Confirm availability through authorized distributors or secondary markets if sourcing for production. Check specific datasheet revisions for any functional changes in surviving stock. Ensure compatibility with existing board designs before procurement due to discontinuation status.
Selection Notes
Select this component only when designing for legacy systems requiring integrated EMI and ESD protection for SD/MMC cards. Consider the 15-XFBGA package constraints during layout. Evaluate alternative active components if new designs are permitted, given the obsolete status. Verify thermal performance requirements against the specified operating temperature range.
Part Context
This component belongs to the EMI7403 series from onsemi, categorized under EMI Filter Circuits. It is part of the broader portfolio of protection devices for consumer electronics. The series focuses on providing compact solutions for noise suppression and surge protection in mobile and portable multimedia applications.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements may require design modifications. Consult onsemi technical support for current equivalent recommendations.
