Substitute Part Grouping Explanation

Substitution for the RT9715GGF is determined by the following critical parameters:

Mandatory Compatibility Criteria:

Output Configuration: High Side, N-Channel, 1:1 ratio
Package / Case: 8-TSSOP or 8-MSOP (0.118", 3.00mm Width)
Voltage - Load: 2.7V ~ 5.5V or compatible subset
Fault Protection: Current Limiting (Fixed), Over Temperature, Reverse Current, UVLO
Interface: On/Off control
Input Type: Non-Inverting

Current Rating Consideration: The RT9715GGF provides 700mA output current. Substitute parts are grouped by their maximum output current capability, allowing selection based on application requirements. Parts with equal or higher current ratings provide direct substitution; parts with lower ratings require application-level current verification.

Voltage Range Consideration: The RT9715GGF operates with load voltages from 2.7V to 5.5V. Substitute parts with identical or broader voltage ranges maintain full compatibility. Parts with narrower ranges (4.5V ~ 5.5V) are suitable only for applications within that restricted range.

Temperature Range Consideration: The RT9715GGF operates from -40°C to 100°C (TJ). Substitute parts with equal or broader temperature ranges provide equivalent thermal performance. Parts with narrower ranges may require thermal analysis for specific applications.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

BD82028FVJ-GE2, BD82030FVJ-GE2, BD82031FVJ-GE2, BD82032FVJ-GE2, and BD82034FVJ-GE2 from Rohm Semiconductor provide the closest functional equivalence to the RT9715GGF. All five parts maintain the load discharge and status flag features, identical fault protection architecture (Current Limiting, Over Temperature, Reverse Current, UVLO), and compatible 8-TSSOP-BJ packaging. These parts are in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The voltage range restriction to 4.5V ~ 5.5V requires application verification for designs operating below 4.5V.

Secondary Substitutes (Voltage Range Compatible):

STMPS2141TTR, STMPS2151TTR, and STMPS2161TTR from STMicroelectronics maintain the full 2.7V ~ 5.5V voltage range and 8-MSOP package compatibility. These parts are in active production with ROHS3 compliance and superior operating temperature range (-40°C ~ 125°C). However, they lack load discharge and status flag features. STMPS2141TTR and STMPS2151TTR provide 500mA output current (below RT9715GGF specification), while STMPS2161TTR provides 1A output current.

Alternative Substitutes (Voltage Range Compatible):

BD82004FVJ-MGE2 and BD82006FVJ-MGE2 from Rohm Semiconductor maintain the full 2.7V ~ 5.5V voltage range and provide 2A and 3A output current respectively. Both are in active production with ROHS3 compliance. These parts lack load discharge and status flag features but offer lower on-resistance (70mOhm vs. 90mOhm).

Product Status Consideration:

All substitute parts listed are in active production status, ensuring long-term availability and supply chain stability compared to the obsolete RT9715GGF.

Frequently Asked Questions (FAQ)

Q: Can BD82028FVJ-GE2 directly replace RT9715GGF in existing designs?

A: BD82028FVJ-GE2 provides functional equivalence with identical load discharge and status flag features, matching fault protection, and compatible 8-TSSOP-BJ packaging. However, the voltage range is restricted to 4.5V ~ 5.5V versus RT9715GGF's 2.7V ~ 5.5V. Direct replacement is possible only for applications operating within the 4.5V ~ 5.5V range. Applications requiring operation below 4.5V require alternative selection.

Q: What is the difference between the Rohm BD82 series parts?

A: The Rohm BD82 series differs primarily in maximum output current rating: BD82028FVJ-GE2 (1A), BD82030FVJ-GE2 (1.5A), BD82031FVJ-GE2 (1.5A), BD82032FVJ-GE2 (2A), and BD82034FVJ-GE2 (2.5A). All maintain identical voltage range (4.5V ~ 5.5V), on-resistance (72mOhm), operating temperature (-40°C ~ 85°C), and feature set (load discharge, status flag). Selection depends on application current requirements.

Q: Why do STMPS2141TTR and STMPS2151TTR have identical specifications?

A: Both parts provide 500mA output current, 2.7V ~ 5.5V voltage range, 110mOhm on-resistance, and -40°C ~ 125°C operating temperature in 8-MSOP packaging. The primary distinction is product designation; both are active production parts from STMicroelectronics suitable for applications requiring lower current than RT9715GGF.

Q: Is package compatibility guaranteed between 8-MSOP and 8-TSSOP?

A: Both 8-MSOP and 8-TSSOP packages share identical physical dimensions (0.118", 3.00mm width) and pin count. PCB footprints are compatible, allowing direct substitution at the board level. However, verify pinout alignment with specific datasheets before implementation.

Q: Which substitute provides the best thermal performance?

A: STMPS2141TTR, STMPS2151TTR, and STMPS2161TTR from STMicroelectronics offer the broadest operating temperature range (-40°C ~ 125°C) compared to RT9715GGF (-40°C ~ 100°C) and Rohm parts (-40°C ~ 85°C). For applications requiring extended high-temperature operation, STMicroelectronics parts provide superior thermal margin.

Q: Can I use BD82006FVJ-MGE2 (3A) as a substitute for RT9715GGF (700mA)?

A: BD82006FVJ-MGE2 provides higher current capability (3A vs. 700mA), full voltage range compatibility (2.7V ~ 5.5V), and lower on-resistance (70mOhm vs. 90mOhm). It is suitable for applications where RT9715GGF current capacity is insufficient. However, it lacks load discharge and status flag features. Verify application requirements for these features before selection.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts listed maintain ROHS3 compliance and REACH unaffected status, matching RT9715GGF environmental compliance. BD82006FVJ-MGE2 additionally carries AEC-Q100 automotive qualification. Verify specific compliance requirements for your application before final selection.
