Frequently Asked Questions (FAQ)

Q: Can BU30SA4WGWL-E2 directly replace BH31SA2WGUT-E2?

A: Both parts belong to the Rohm Semiconductor power management IC family. Substitution feasibility depends on matching the specific electrical characteristics and package footprint requirements of your application. Detailed electrical parameter alignment must be verified against your circuit design requirements.

Q: What is the significance of "Last Time Buy" and "Not For New Designs" status?

A: Last Time Buy indicates the original part has reached end-of-life with limited remaining stock. Not For New Designs indicates the substitute part is also in end-of-life phase. Both statuses require careful inventory planning for long-term production support.

Q: Are there packaging differences between these parts?

A: BU30SA4WGWL-E2 is specified as Tape & Reel (TR) packaging. The packaging specification for BH31SA2WGUT-E2 is not provided in available data. Verify package compatibility with your assembly equipment and PCB footprint requirements.

Q: What compliance certifications apply to the substitute part?

A: BU30SA4WGWL-E2 carries ROHS3 compliance, indicating conformance to Restriction of Hazardous Substances Directive. REACH Unaffected status indicates the part is not subject to REACH chemical restrictions. These certifications support use in regulated applications.
