Procurement Notes

Verify the complete part number including suffixes against official ABLIC documentation to ensure correct output voltage and package variant. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Cross-reference the datasheet revision date to validate electrical characteristics and thermal specifications before finalizing component selection for production.

Selection Notes

Select this component when designing circuits powered by single-cell lithium-ion or lithium-polymer batteries where maintaining system uptime during low-battery states is critical. Ensure the external inductor and diode ratings exceed the maximum switch current limits specified in the technical data sheet. Verify that the required output voltage matches the fixed internal reference to avoid unnecessary feedback network complexity.

Part Context

This model belongs to the S-8358 series of step-up switching regulators from ABLIC. The series is characterized by its ability to operate with minimal input voltage, making it ideal for energy harvesting and low-voltage battery applications. The specific suffix indicates the fixed output voltage level and the tape-and-reel packaging format for automated assembly.

Replacement Considerations

Direct replacements include other S-8358 series variants with compatible output voltages such as S-8358J33MC-NWST2U or S-8358F33MC-MKST2U if a 3.3V output is acceptable. Verify pin compatibility and thermal performance when substituting with different package types within the same product family.
