Procurement Notes
Verify RoHS compliance status through official datasheets, as sources indicate non-compliance for some variants. Confirm moisture sensitivity level (MSL 3) handling requirements before assembly. Check current availability and lead times directly with the manufacturer or authorized distributors, as stock levels vary by region and specific suffix codes.
Selection Notes
Select this component for standard 10/100 Mbps Ethernet physical layer designs requiring integrated common mode chokes. Ensure the SMD-24 package dimensions fit the board layout constraints. Verify that the specific suffix variant meets regulatory requirements for the target market, particularly regarding lead-free standards.
Part Context
This part belongs to the iNRCORE 100B series of LAN transformers. It serves as a critical passive component in Ethernet PHY interfaces, providing impedance matching and noise suppression. Similar parts include the 100B-1011T and 100B-1011F, which share the same core functionality but may differ in packaging or compliance specifications.
Replacement Considerations
Direct substitutes include the 100B-1011T and 100B-1011F from iNRCORE. Cross-brand replacements require verification of pinout compatibility, electrical parameters, and package dimensions to ensure functional equivalence in the specific circuit design.
