Procurement Notes
This component is officially classified as obsolete and no longer manufactured by Littelfuse Inc. Procurement should focus on verified direct substitute part numbers available from authorized distributors. Verify that replacement components match electrical ratings and physical footprint requirements before integration into production designs.
Selection Notes
Designers must account for the discontinued status when selecting this component. Alternative solutions require matching the 6V max voltage and 100mA hold current specifications. Ensure the substitute maintains the same 0402 package dimensions and operating temperature range to guarantee compatibility with existing board layouts and thermal management strategies.
Part Context
The 0402L010SLYR belongs to the Littelfuse LoRho series of PPTC resettable fuses. This series is characterized by low resistance values and compact surface mount packaging suitable for space-constrained applications. The component serves as a reusable alternative to traditional one-time fusible links in low-voltage DC circuits.
Replacement Considerations
Direct substitutes include the 0402L020SLKR from Littelfuse Inc. Verify that the replacement part meets all original electrical and mechanical specifications for seamless integration.
