Engineering Selection Recommendations
Primary Recommendation - AL8860MP-13 (Diodes Incorporated): The AL8860MP-13 is the manufacturer-recommended direct replacement. It maintains the same 8-MSOP-EP package footprint, identical 1MHz switching frequency, and dual Analog/PWM dimming capability. The AL8860MP-13 offers improved specifications with 1.5A output current (15% higher than the original 1.3A), extended maximum supply voltage to 40V (vs. 36V), and Active product status ensuring long-term availability. Operating temperature range is -40°C to 105°C, which covers the majority of industrial applications. ROHS3 compliance and MSL-1 rating are maintained.
Secondary Recommendation - LM3404MA/NOPB (Texas Instruments): The LM3404MA/NOPB provides a robust alternative with Active status and automotive qualification (AEC-Q100). It delivers 1A output current in an 8-SOIC package with 1MHz operation and PWM dimming. Supply voltage range of 6V to 42V accommodates the original 6V to 36V requirement. Operating temperature extends to -40°C to 125°C, matching the original specification. This part is suitable for designs where package migration from MSOP to SOIC is acceptable.
Tertiary Recommendation - IS31LT3353-V1STLS2-TR (ISSI): The IS31LT3353-V1STLS2-TR offers a compact SOT-23-5 package alternative with 1A output current, 1MHz frequency, and dual Analog/PWM dimming matching the original feature set. Supply voltage range of 6V to 40V and operating temperature of -40°C to 125°C align with the original specifications. This option is preferred for space-constrained applications where package miniaturization is beneficial.
Not Recommended for Direct Substitution:
- BU90030G-TR: Switched Capacitor topology (not Buck), 80mA output (insufficient for 1.3A requirement), 2V to 4V supply range (incompatible with 6V minimum)
- LM2705MFX-ADJ/NOPB: Step-Up (Boost) topology (not Buck), 150mA output (insufficient), 2.2V to 7V supply range (incompatible with 6V to 36V requirement)
- LM3402MM/NOPB: 500mA output current (below 1.3A requirement)
- LED2001PHR: 3V to 18V supply range (below 6V minimum requirement)
- A6213KLJTR-T: 8-SOIC package (different from 8-MSOP), higher current rating (3A) may require circuit redesign
Frequently Asked Questions (FAQ)
Q: Can the AL8860MP-13 be used as a direct drop-in replacement for the AL8807MP-13?
A: Yes. Both parts share the identical 8-MSOP-EP package footprint, 1MHz switching frequency, and Analog/PWM dimming capability. The AL8860MP-13 maintains pin-compatible operation with improved current rating (1.5A vs. 1.3A) and extended supply voltage range (40V vs. 36V). No circuit modifications are required for standard applications operating within the original 6V to 36V supply range.
Q: What is the key difference between the AL8807MP-13 and AL8807QMP-13?
A: The AL8807QMP-13 is an automotive-qualified variant (AEC-Q100) of the same base AL8807 device. Both deliver 1.3A output current at 1MHz with Analog/PWM dimming in the 8-MSOP-EP package. The AL8807QMP-13 has a reduced maximum supply voltage of 30V (vs. 36V) and maintains Obsolete status. For automotive applications, the AL8860MP-13 is preferred due to its Active status and higher current rating.
Q: Why is the BU90030G-TR not suitable as a substitute?
A: The BU90030G-TR uses Switched Capacitor (Charge Pump) topology, fundamentally different from the Buck topology of the AL8807MP-13. Additionally, it delivers only 80mA output current (insufficient for the 1.3A requirement) and operates on a 2V to 4V supply range (incompatible with the 6V to 36V requirement of the original part).
Q: Can I use the LM3404MA/NOPB if my PCB layout uses an 8-SOIC package instead of 8-MSOP?
A: Yes, if your design already accommodates an 8-SOIC footprint. The LM3404MA/NOPB provides 1A output current, 1MHz operation, and PWM dimming within a 6V to 42V supply range and -40°C to 125°C operating temperature. However, if your current design uses 8-MSOP, the AL8860MP-13 is the preferred choice to avoid PCB layout modifications.
Q: What is the significance of the MSL (Moisture Sensitivity Level) rating?
A: MSL-1 (Unlimited) indicates the component has no moisture sensitivity restrictions and does not require special handling, storage, or baking procedures before soldering. Both the AL8807MP-13 and recommended substitutes (AL8860MP-13, LM3404MA/NOPB) carry MSL-1 ratings, ensuring consistent manufacturing and assembly processes.
Q: Are all recommended substitutes ROHS3 compliant?
A: Yes. The AL8860MP-13, LM3404MA/NOPB, and IS31LT3353-V1STLS2-TR all carry ROHS3 Compliant certification, matching the original AL8807MP-13. This ensures compatibility with environmental regulations and customer requirements for lead-free manufacturing.
Q: What is the difference between Analog and PWM dimming?
A: Analog dimming adjusts LED brightness by varying the output voltage or current through an analog control signal. PWM (Pulse Width Modulation) dimming controls brightness by switching the output on and off at high frequency, varying the duty cycle. The AL8807MP-13 supports both methods, providing design flexibility. The AL8860MP-13 and IS31LT3353-V1STLS2-TR maintain this dual capability, while some alternatives (LM3404MA/NOPB, LED2001PHR) support PWM only.
Q: Can the IS31LT3353-V1STLS2-TR be used in applications requiring the full 1.3A output current?
A: The IS31LT3353-V1STLS2-TR delivers 1A output current, which is 77% of the original 1.3A specification. For applications requiring the full 1.3A or higher, the AL8860MP-13 (1.5A) or A6213KLJTR-T (3A) are more appropriate. If your application can operate at 1A, the IS31LT3353-V1STLS2-TR offers a compact SOT-23-5 package advantage.
