Procurement Notes
This component is currently classified as obsolete and no longer manufactured by Bel Fuse Inc. Procurement should focus on identifying verified direct substitutes or alternative manufacturers offering equivalent electrical specifications. Verify that replacement parts meet the required AEC-Q200 standards if used in automotive applications. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing any sourcing decisions.
Selection Notes
Select this component only when its specific 30V rating and 200mA hold current align precisely with circuit design requirements. Consider the 1812 package size constraints and the need for AEC-Q200 compliance. Due to its obsolete status, engineers must evaluate alternative solutions that match the original electrical parameters and physical dimensions to ensure seamless integration into existing designs without redesigning the board layout.
Part Context
The 0ZCC series belongs to Bel Fuse's portfolio of polymeric PTC resettable fuses. These devices are engineered for circuit protection in space-constrained applications. The 0ZCC0020FF2C specifically targets automotive and industrial sectors where reliability under varying thermal conditions is critical. Its classification as obsolete indicates it has been superseded by newer generations within the manufacturer's lineup.
Replacement Considerations
Direct substitute part numbers are not explicitly confirmed in the provided documentation. Engineers should consult official distributor databases for cross-references from manufacturers like Littelfuse or Bourns that offer matching 1812 PTC fuses with comparable 30V/200mA ratings and AEC-Q200 certification.
