Engineering Selection Recommendations

For Applications Requiring Full Feature Parity (Load Discharge + Status Flag): BD82028FVJ-GE2, BD82030FVJ-GE2, BD82031FVJ-GE2, or BD82034FVJ-GE2 are recommended. These Rohm parts maintain load discharge and status flag functionality. Selection depends on required output current: BD82028FVJ-GE2 for 1A, BD82030FVJ-GE2 or BD82031FVJ-GE2 for 1.5A, and BD82034FVJ-GE2 for 2.5A. All operate at -40°C ~ 85°C and are ROHS3 compliant with MSL 1 rating.

For Applications with Extended Load Voltage Range (2.7V ~ 5.5V): BD82005FVJ-MGE2 (2A) or BD82007FVJ-MGE2 (3A) provide full 2.7V ~ 5.5V load voltage compatibility with automotive qualification (AEC-Q100). These are suitable for designs not requiring load discharge or status flag features.

For Applications with Extended Operating Temperature Range: STMPS2161TTR supports -40°C ~ 125°C operating temperature with 1A output current and 2.7V ~ 5.5V load voltage range. STMPS2141TTR and STMPS2151TTR provide 500mA alternatives with the same temperature range. These STMicroelectronics parts do not include load discharge or status flag features.

Compliance Considerations: All substitute parts are ROHS3 compliant and REACH unaffected. Rohm parts with automotive qualification (BD82005FVJ-MGE2, BD82007FVJ-MGE2) carry AEC-Q100 certification. MSL ratings vary: Rohm parts are MSL 1 (Unlimited), while the original RT9715HGF is MSL 3 (168 Hours).

Frequently Asked Questions (FAQ)

Q: Can BD82028FVJ-GE2 directly replace RT9715HGF in existing designs? A: BD82028FVJ-GE2 matches the RT9715HGF in topology, load discharge, and status flag features. However, the load voltage range is restricted to 4.5V ~ 5.5V versus the RT9715HGF's 2.7V ~ 5.5V. Verify your application operates within the 4.5V ~ 5.5V window. Package compatibility is confirmed (8-TSSOP-BJ vs. 8-MSOP, both 0.118" width).

Q: What is the difference between Rohm BD82005FVJ-MGE2 and BD82028FVJ-GE2? A: BD82005FVJ-MGE2 supports 2.7V ~ 5.5V load voltage with 2A output current and automotive qualification (AEC-Q100). BD82028FVJ-GE2 is restricted to 4.5V ~ 5.5V load voltage with 1A output current but includes load discharge and status flag features. Select based on voltage range requirements and feature necessity.

Q: Are STMicroelectronics STMPS parts suitable for USB switch applications? A: STMPS2141TTR, STMPS2151TTR, and STMPS2161TTR are classified as general-purpose switches rather than USB-specific switches. They provide matching topology and fault protection but lack load discharge and status flag features. Verify application requirements before substitution.

Q: What is the impact of different Rds On values? A: RT9715HGF has 90mOhm Rds On (Typ). Rohm BD82 series parts have 70mOhm (lower resistance, better efficiency). STMicroelectronics STMPS parts have 110mOhm (higher resistance, slightly higher power dissipation). Select based on thermal and efficiency requirements.

Q: Can I use a higher current-rated part as a substitute? A: Yes. Higher current-rated parts (BD82007FVJ-MGE2 at 3A, BD82034FVJ-GE2 at 2.5A) are backward compatible with 700mA load requirements. Verify package footprint compatibility and thermal management for your PCB layout.

Q: What is the MSL rating difference between RT9715HGF and substitute parts? A: RT9715HGF is MSL 3 (168 Hours), requiring moisture control during storage and handling. Rohm and STMicroelectronics substitutes are MSL 1 (Unlimited), offering more relaxed moisture sensitivity requirements and longer shelf life.

Q: Are there package compatibility concerns? A: RT9715HGF uses 8-MSOP packaging. Rohm substitutes use 8-TSSOP-BJ. Both are 0.118" (3.00mm) width with 8-pin configuration
