Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSL1064AW-R is determined by the following critical parameters:

• Number of Outputs: 6 channels required
• Topology: Step-Up (Boost) regulator with internal switching capability
• Output Voltage Range: Capable of reaching 48V or higher
• Output Current: Minimum 30mA per channel
• Dimming Control: Support for analog and/or PWM dimming
• Operating Temperature: -40°C to 85°C minimum
• Package Type: Surface mount with exposed pad
• Supply Voltage Range: Compatibility with 4.75V to 36V input range
• Compliance: ROHS3 compliant

The substitute parts listed below meet these core functional requirements while maintaining electrical and mechanical compatibility for backlight LED driver applications.

Parameter Comparison

Engineering Selection Recommendations

ISL97693IRTZ (Renesas Electronics Corporation) is the primary recommended substitute. This part maintains Step-Up (Boost) topology with 6 outputs and 30mA per channel current rating. The device is in active product status, ensuring long-term availability and support. Operating temperature range of -40°C to 85°C matches the original specification. ROHS3 compliance is maintained. The 16-TQFN (3x3) package requires PCB layout redesign compared to the 24-WQFN original, but electrical functionality is directly compatible.

MPQ3387LGRT-Z (Monolithic Power Systems Inc.) provides an alternative with higher output current capability (45mA per channel) and automotive-grade qualification (AEC-Q100). This part is in active status with ROHS3 compliance. The 24-TQFN (4x4) package footprint is similar to the original, minimizing layout changes. Supply voltage range of 3V to 25V is narrower than the original but suitable for most backlight applications.

RT8567GQW (Richtek USA Inc.) offers active product status with flexible frequency range (500kHz to 2MHz) and 40mA per channel output current. The 20-WQFN (3x3) package represents a moderate footprint change. Operating temperature and ROHS3 compliance align with original specifications.

FAN5702UC30X (onsemi) uses Switched Capacitor (Charge Pump) topology rather than Step-Up (Boost), representing a functional alternative for lower supply voltage applications (2.7V to 5.5V). This part is obsolete, limiting its suitability for new designs requiring long-term availability.

Frequently Asked Questions (FAQ)

Q: Can FAN5702UC30X replace MSL1064AW-R directly?

A: FAN5702UC30X uses Switched Capacitor (Charge Pump) topology instead of Step-Up (Boost). While both are 6-output LED drivers with 30mA per channel, the charge pump topology operates within a narrower supply voltage range (2.7V to 5.5V) compared to the original (4.75V to 36V). Additionally, FAN5702UC30X is obsolete. Direct replacement requires circuit redesign and is not recommended for new designs.

Q: What is the primary difference between ISL97693IRTZ and MSL1064AW-R?

A: Both devices use Step-Up (Boost) topology with 6 outputs and 30mA per channel. The main differences are package size (16-TQFN versus 24-WQFN) and product status (ISL97693IRTZ is active). ISL97693IRTZ has a lower minimum supply voltage (2.4V versus 4.75V) and lower maximum output voltage (26V versus 48V). PCB layout redesign is required due to package change.

Q: Is MPQ3387LGRT-Z suitable for applications requiring 30mA per channel?

A: Yes. MPQ3387LGRT-Z provides 45mA per channel output current, which exceeds the 30mA requirement of MSL1064AW-R. The higher current capability ensures compatibility with existing designs. The part is automotive-qualified (AEC-Q100) and in active status.

Q: What are the package compatibility considerations?

A: MSL1064AW-R uses 24-WQFN Exposed Pad. Substitute parts use different packages: ISL97693IRTZ (16-TQFN), FAN5702UC30X (16-WLCSP), MPQ3386DR-LF-P (24-VFQFN), MPQ3387LGRT-Z (24-WFQFN), and RT8567GQW (20-WQFN). Package changes require PCB layout redesign and re-qualification of thermal performance.

Q: Why is product status important for selection?

A: Active product status ensures manufacturer support, continued availability, and potential design improvements. ISL97693IRTZ, MPQ3386DR-LF-P, MPQ3387LGRT-Z, and RT8567GQW are all in active status, providing long-term supply chain security. FAN5702UC30X and MSL1064AW-R are both obsolete, limiting their use to legacy system support only.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the environmental and regulatory requirements of the original MSL1064AW-R.
