Procurement Notes

Verify the complete part number including suffixes against official ABLIC documentation to ensure correct voltage and package specifications. Confirm RoHS compliance status through manufacturer datasheets or certificates of conformity prior to integration. Cross-reference ordering information with authorized distributors to validate availability and authenticity.

Selection Notes

Select this component when a fixed 4.8 V output is required from a lower input voltage source. Ensure the application load current does not exceed the specified 54.8 mA limit. Verify that the operating temperature range of -40°C to +85°C aligns with the environmental conditions of the target system.

Part Context

This device is part of the S-8357 series, which includes various fixed-output step-up controllers. Other variants in this family offer different output voltages such as 5.0 V or 3.3 V, sharing similar operational characteristics and packaging options while catering to specific voltage rail requirements.

Replacement Considerations

Compatible substitutes include other S-8357 series models like S-8357F50MC-MHJT2U for 5.0 V outputs or S-8357G32MC-MIRT2U for 3.2 V outputs, provided the voltage requirement differs.
