RT9715AGF Equivalent & Substitute Parts

Part Overview

The RT9715AGF is a Power Switch/Driver IC manufactured by Richtek USA Inc., designed for 1:1 N-Channel high-side switching applications with 2A maximum output current. This component operates across a 2.7V to 5.5V load voltage range and integrates load discharge, status flag, and comprehensive fault protection including current limiting, over-temperature, reverse current, and UVLO (Under-Voltage Lock-Out) functions. The device is packaged in 8-MSOP format with RoHS3 compliance.

The RT9715AGF is currently classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this power switch topology.

Current Rating: Minimum 2A output capability (equal or greater)
Voltage Range: Load voltage compatibility with 2.7V ~ 5.5V operating window
Fault Protection: Current Limiting (Fixed), Over Temperature, and Reverse Current protection
Package Compatibility: 8-TSSOP or 8-MSOP form factor (0.118", 3.00mm Width)
Interface: On/Off control, Non-Inverting input type

Secondary Considerations:

Rds On (On-Resistance): Lower values indicate improved efficiency; 90mOhm baseline

Engineering Selection Recommendations

Primary Substitutes (Full Compatibility):

BD82024FVJ-E2 (Rohm Semiconductor) is the closest functional equivalent. It maintains the 2.5A current rating, identical Rds On specification (90mOhm), and preserves all critical features including load discharge and status flag. The voltage range (2.8V ~ 5.5V) is compatible with the RT9715AGF application window. Active product status ensures supply continuity. The 8-TSSOP-BJ package is mechanically compatible with the 8-MSOP footprint. RoHS3 compliance is maintained.

BD82032FVJ-GE2 (Rohm Semiconductor) provides 2A output current with improved Rds On (72mOhm) and full feature parity. The voltage range is restricted to 4.5V ~ 5.5V, limiting applicability to designs not requiring the extended 2.7V lower threshold. Active status and RoHS3 compliance are confirmed.

Secondary Substitutes (Current Rating Upgrade):

BD82006FVJ-MGE2 (Rohm Semiconductor) offers 3A output capability with superior Rds On (70mOhm). The 2.7V ~ 5.5V voltage range matches the original specification. However, load discharge and status flag features are not listed. Active product status and RoHS3 compliance are maintained. This option suits applications requiring increased current headroom.

BD82034FVJ-GE2 (Rohm Semiconductor) provides 2.5A output with 72mOhm Rds On and full feature set. Voltage range limitation (4.5V ~ 5.5V) applies. Active status and compliance confirmed.

Downgrade Substitutes (Current Rating Reduction):

BD82028FVJ-GE2, BD82030FVJ-GE2, and BD82031FVJ-GE2 (Rohm Semiconductor) offer 1A and 1.5A ratings respectively. These are suitable only for applications where the original 2A requirement can be reduced. Voltage range is restricted to 4.5V ~ 5.5V. All maintain full feature sets and active status.

STMPS2141TTR and STMPS2151TTR (STMicroelectronics) provide 500mA output with 110mOhm Rds On. These represent significant current derating and are applicable only to low-power applications. The 2.7V ~ 5.5V voltage range is compatible. Extended operating temperature (-40°C ~ 125°C) is available. Load discharge and status flag features are not listed. Active status and RoHS3 compliance are confirmed.

Frequently Asked Questions (FAQ)

Q: Can BD82024FVJ-E2 directly replace RT9715AGF in existing designs?

A: BD82024FVJ-E2 is functionally compatible for applications operating within the 2.8V ~ 5.5V range. The 8-TSSOP-BJ package is mechanically compatible with 8-MSOP footprints. Verify PCB layout compatibility and confirm that the minimum voltage requirement of 2.8V (versus 2.7V) does not impact your application. All critical protection features and output current capability are preserved.

Q: What is the difference between Rohm BD82xxx and STMicroelectronics STMPS2xxx series?

A: Both series provide 1:1 N-Channel high-side switching with comparable fault protection. Rohm BD82xxx parts offer load discharge and status flag features across most models, while STMicroelectronics STMPS2xxx parts focus on core protection functions. Rohm parts support extended voltage ranges (2.7V ~ 5.5V), whereas STMicroelectronics STMPS2141/2151 also support this range but with lower current ratings (500mA).

Q: Is the 8-TSSOP-BJ package pin-compatible with 8-MSOP?

A: Both packages share the same 0.118" (3.00mm) width and 8-pin configuration. Pin assignments must be verified against individual datasheets to confirm functional compatibility. The package designation difference (TSSOP-BJ versus MSOP) indicates manufacturing origin but does not preclude electrical equivalence.

Q: Why do some substitutes have restricted voltage ranges (4.5V ~ 5.5V)?

A: Certain Rohm BD82xxx variants are optimized for USB power delivery applications where 5V nominal operation is standard. These parts are not suitable for applications requiring the full 2.7V ~ 5.5V range. Confirm your application's minimum operating voltage before selecting a restricted-range substitute.

Q: Can I use BD82006FVJ-MGE2 (3A) as a drop-in replacement for 2A applications?

A: Yes. Higher current-rated devices are backward-compatible with lower-current applications. BD82006FVJ-MGE2 provides improved thermal margin and reduced Rds On (70mOhm versus 90mOhm). However, verify that load discharge and status flag features are not required by your design, as this part does not list these features.

Q: What is the significance of "Active" versus "Obsolete" product status?

A: Active products have confirmed ongoing manufacturing and supply availability. Obsolete products (RT9715AGF) are no longer manufactured and existing inventory is finite. Selecting an active substitute ensures long-term design support and production continuity.

Q: Are all listed substitutes RoHS3 compliant?

A: Yes. All substitute parts listed maintain RoHS3 compliance and REACH unaffected status, matching the environmental and regulatory requirements of the original RT9715AGF.
