Procurement Notes
This component is currently obsolete and has reached end-of-life status. The manufacturer has discontinued production, and the factory is not accepting new orders. Verification of availability through secondary distributors is required, though supply is limited. Buyers should confirm part authenticity and storage conditions due to the discontinued status.
Selection Notes
Engineers selecting this part must account for its obsolete status and plan for long-term supply risks. The 35 pF capacitance and RC Pi topology define its filtering characteristics. Alternative components with similar package dimensions and electrical specifications should be evaluated to ensure design continuity and future manufacturability.
Part Context
The IP4058CX8/LF,135 belongs to the NXP EMI filter circuit category. It is specifically categorized as an LC or RC network filter. The device is intended for use in applications requiring compact footprint solutions for signal integrity management. It falls under the broader class of passive filtering components used in consumer electronics.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers must identify cross-reference parts based on matching package type (WLCSP-8), capacitance values, and filtering performance requirements.
