Substitute Part Grouping Explanation

Substitution for the BH28SA2WGUT-E2 is based on functional equivalence within the power management IC category. The qualified substitute part BU28SA4WGWL-E2 shares the same manufacturer (Rohm Semiconductor) and operates within compatible electrical parameters. The substitution logic is grounded in the following criteria:

• Functional category: Power Management (PMIC)
• Manufacturer alignment: Both parts from Rohm Semiconductor
• Electrical compatibility: Output configuration, voltage ratings, and current delivery specifications
• Compliance standards: RoHS3 compliance and REACH status alignment
• Packaging compatibility: Surface mount technology

Parameter Comparison

Engineering Selection Recommendations

The BU28SA4WGWL-E2 is the qualified substitute for the BH28SA2WGUT-E2. Both parts are manufactured by Rohm Semiconductor and maintain surface mount compatibility. The substitute part carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. The BU28SA4WGWL-E2 is currently available with higher inventory levels (2867 Pcs) compared to the original part (624 Pcs), providing improved supply security.

Selection of the substitute part should be based on verification that the specified electrical parameters (2.8V fixed output, 200mA current delivery, -40°C to 85°C operating range) align with application requirements. The substitute part is marked as Not For New Designs, indicating it is also subject to discontinuation planning and should be considered a transitional solution.

Frequently Asked Questions (FAQ)

Q: Why is the BH28SA2WGUT-E2 being discontinued? A: The part has reached Last Time Buy status, which is a standard lifecycle phase for electronic components. Manufacturers discontinue parts to focus resources on newer technologies and product lines.

Q: Is the BU28SA4WGWL-E2 a direct replacement? A: The BU28SA4WGWL-E2 is a qualified substitute within the power management IC category from the same manufacturer. Compatibility depends on your application's specific electrical requirements, particularly output voltage, current delivery, and operating temperature range.

Q: What are the key electrical differences? A: The substitute part specifies a 2.8V fixed output with 200mA current delivery capability, 0.15V maximum dropout voltage at 100mA, and 80µA quiescent current. Verify these parameters match your application requirements before implementation.

Q: Are there packaging differences? A: Both parts use surface mount technology. The substitute part is specified as 4-UFBGA, CSPBGA package type with UCSP50L1 supplier device package designation. Confirm PCB layout compatibility with your existing design.

Q: What compliance certifications apply? A: The substitute part is ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory standards for electronic components.

Q: How long will the substitute part remain available? A: The BU28SA4WGWL-E2 is marked as Not For New Designs, indicating it is also subject to future discontinuation. For long-term supply planning, evaluate additional alternatives or engage with Rohm Semiconductor for extended availability options.
