RT9715CGF Equivalent & Substitute Parts

Part Overview

The RT9715CGF is a Power Switch/Driver IC manufactured by Richtek USA Inc., designed as a 1:1 N-Channel high-side switch with 1.5A output capacity in an 8-MSOP package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The RT9715CGF operates across a 2.7V to 5.5V load voltage range and includes integrated load discharge, status flag, and comprehensive fault protection including current limiting, over-temperature, reverse current, and UVLO functions.

Substitute Part Grouping Explanation

Substitution for the RT9715CGF is determined by the following critical parameters:

Output current capacity (1.5A nominal)
Load voltage range compatibility (2.7V ~ 5.5V or subset thereof)
High-side N-Channel output configuration with 1:1 ratio
Package compatibility (8-MSOP or 8-TSSOP, both 0.118" width)
Fault protection features (current limiting, over-temperature, reverse current, UVLO)
On-resistance characteristics (Rds On in the 70-110mOhm range)
Surface mount technology

Substitute parts are grouped into two categories: direct equivalents matching the 1.5A specification, and higher-current alternatives (2A, 2.5A, 3A) suitable for applications with headroom requirements. Lower-current alternatives (500mA, 1A) are included for current-limited applications.

Engineering Selection Recommendations

Primary Direct Equivalent (Recommended for 1.5A applications): MIC2544-2YMM from Microchip Technology matches the RT9715CGF across all critical parameters: 1.5A output current, 2.7V to 5.5V load voltage range, 8-MSOP package, and active product status. This part maintains the same thermal operating range and provides status flag functionality. ROHS3 compliance and unlimited MSL rating ensure manufacturing compatibility.

Alternative Direct Equivalent (Rohm Semiconductor): BD82030FVJ-GE2 and BD82031FVJ-GE2 both deliver 1.5A in 8-TSSOP-BJ packaging with active status. These parts operate within a narrower voltage range (4.5V ~ 5.5V) and lower operating temperature maximum (-40°C ~ 85°C TA), requiring verification against application requirements. Both include load discharge and status flag features matching the original specification.

Higher Current Alternatives (Design Margin Applications): BD82032FVJ-GE2 (2A) and BD82034FVJ-GE2 (2.5A) provide increased current headroom while maintaining the same 8-TSSOP-BJ package footprint and active product status. These are suitable for applications requiring design margin above the 1.5A specification, provided the narrower voltage range (4.5V ~ 5.5V) is acceptable.

Extended Voltage Range Alternative: BD82004FVJ-MGE2 and BD82006FVJ-MGE2 support the full 2.7V to 5.5V load voltage range matching the original part, with higher current ratings (2A and 3A respectively). These are appropriate for low-voltage applications below 4.5V that require higher current capacity.

Lower Current Alternatives (Current-Limited Applications): STMPS2141TTR and STMPS2151TTR from STMicroelectronics provide 500mA output in 8-MSOP packaging with extended operating temperature range (-40°C ~ 125°C TJ). These are suitable only for applications with reduced current requirements and offer the widest temperature specification.

All recommended substitutes maintain ROHS3 compliance and EAR99 export classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can BD82030FVJ-GE2 replace RT9715CGF in all applications? A: BD82030FVJ-GE2 is a functional equivalent for 1.5A applications but operates within a narrower load voltage range (4.5V ~ 5.5V versus 2.7V ~ 5.5V). Applications requiring operation below 4.5V require alternative selection such as MIC2544-2YMM or BD82004FVJ-MGE2.

Q: What is the difference between 8-MSOP and 8-TSSOP packaging? A: Both packages share identical 0.118" (3.00mm) width and pin count, with compatible PCB footprints for most applications. Verify specific land pattern requirements in component datasheets before layout finalization.

Q: Is MIC2544-2YMM a direct pin-for-pin replacement? A: MIC2544-2YMM matches the RT9715CGF in package type (8-MSOP), pin count, and electrical specifications. Pin-level compatibility requires verification against detailed pinout diagrams in both datasheets.

Q: Why do some substitutes have narrower voltage ranges? A: Rohm Semiconductor BD82030/BD82031/BD82032/BD82034 series are optimized for 4.5V to 5.5V USB power applications, while Richtek RT9715CGF and Microchip MIC2544-2YMM support extended low-voltage operation down to 2.7V. Application voltage requirements determine appropriate selection.

Q: Can I use a higher-current part like BD82034FVJ-GE2 (2.5A) as a drop-in replacement? A: BD82034FVJ-GE2 provides functional equivalence with increased current capacity and identical package footprint. Verify that the narrower voltage range (4.5V ~ 5.5V) and lower maximum operating temperature (-40°C ~ 85°C TA) meet application requirements.

Q: What is the significance of the "Load Discharge" feature? A: Load discharge capability allows the switch to actively discharge the load when disabled, preventing voltage overshoot and protecting downstream circuitry. RT9715CGF, BD82028FVJ-GE2, BD82030FVJ-GE2, BD82031FVJ-GE2, and BD82032FVJ-GE2 include this feature; lower-current alternatives do not.

Q: Are all substitutes ROHS3 compliant? A: All listed substitute parts maintain ROHS3 compliance matching the original RT9715CGF specification, ensuring compatibility with environmental and regulatory requirements.
