Engineering Selection Recommendations

Recommended Primary Substitutes (Active Status, Direct Replacement):

AL8860MP-13 and AL8861MP-13 are the preferred substitutes. Both are manufactured by Diodes Incorporated, maintain identical 8-MSOP-EP packaging, and feature enhanced specifications including higher current rating (1.5A vs. 1.3A), extended supply voltage range (4.5V to 40V), and dual dimming modes (Analog + PWM). Both are ROHS3 compliant with MSL-1 rating. AL8860MP-13 supports -40°C to 105°C; AL8861MP-13 supports -40°C to 85°C. Selection between these two depends on thermal operating requirements.

Secondary Substitutes (Active Status, Package or Current Variation):

LM3414HVSD/NOPB (Texas Instruments) provides equivalent functionality in 8-WSON package with extended supply voltage range (4.5V to 65V) and automotive-grade qualification. Current rating is 1A, which is lower than the original 1.3A but acceptable for many LED driver applications. Frequency is 500kHz versus 1MHz.

A6214KLKTR-T (Allegro MicroSystems) offers higher current capability (2A) in 10-SOIC package with automotive qualification (AEC-Q100) and extended temperature range (-40°C to 125°C). Package size increase and higher current rating make this suitable for higher-power LED applications.

Conditional Substitutes (Obsolete or Topology Mismatch):

ILD6070XUMA1 (Infineon Technologies) is also obsolete but remains available in inventory. It provides compatible buck topology with lower current rating (700mA) and extended temperature range (-40°C to 150°C). Not recommended for new designs due to obsolete status.

IS31BL3508A-TTLS2-TR uses Step-Up (Boost) topology and is not suitable as a direct substitute for buck-only applications requiring step-down voltage conversion.

LM3405XMKX/NOPB operates at 3V minimum input, making it unsuitable for the 6V minimum requirement of the original part.

Compliance Verification:

All recommended substitutes maintain ROHS3 compliance and EAR99 ECCN classification. MSL ratings vary (MSL-1 preferred for unlimited shelf life; MSL-2 and MSL-3 require controlled storage conditions).

Frequently Asked Questions (FAQ)

Q: Can AL8860MP-13 or AL8861MP-13 directly replace AL8807BMP-13 without PCB redesign?

A: Yes, both parts use identical 8-MSOP-EP packaging with the same pinout and footprint. No PCB layout changes are required. The enhanced specifications (higher current, extended voltage range, dual dimming modes) provide improved performance margins.

Q: What is the difference between AL8860MP-13 and AL8861MP-13?

A: Both parts are functionally identical with the same electrical specifications. The primary difference is operating temperature range: AL8860MP-13 supports -40°C to 105°C, while AL8861MP-13 supports -40°C to 85°C. Select based on your application's thermal requirements.

Q: Why is HV9967BK7-G not recommended as a direct substitute despite being active?

A: HV9967BK7-G has a minimum supply voltage of 8V, which exceeds the original part's 6V minimum requirement. Applications requiring 6V operation would not function with this part. Additionally, the current rating is lower (750mA vs. 1.3A).

Q: Can LM3414HVSD/NOPB be used in place of AL8807BMP-13?

A: LM3414HVSD/NOPB is functionally compatible with identical buck topology, PWM dimming, and -40°C to 125°C temperature range. However, the current rating is lower (1A vs. 1.3A), and the switching frequency is 500kHz versus 1MHz. It is suitable only if your application's current requirements do not exceed 1A and lower switching frequency is acceptable.

Q: What does MSL rating mean, and why does it matter?

A: MSL (Moisture Sensitivity Level) indicates how long a component can be stored in standard conditions before requiring baking before reflow soldering. MSL-1 (Unlimited) requires no special storage. MSL-2 and MSL-3 require controlled humidity storage and baking procedures before assembly. AL8807BMP-13 and most recommended substitutes are MSL-1.

Q: Is A6214KLKTR-T suitable for my application if I need higher current capability?

A: A6214KLKTR-T provides 2A current capability in a 10-SOIC package with automotive qualification. It is suitable if your application requires higher current and you can accommodate the larger package footprint. PCB redesign is required due to different package size and pinout.

Q: Why is IS31BL3508A-TTLS2-TR listed but not recommended?

A: IS31BL3508A-TTLS2-TR uses Step-Up (Boost) topology, which increases voltage rather than decreasing it. The original AL8807BMP-13 uses Step-Down (Buck) topology for voltage reduction. These topologies serve different applications and are not interchangeable.

Q: Can I use LM3405XMKX/NOPB if my supply voltage is above 3V?

A: LM3405XMKX/NOPB has a maximum supply voltage of 15V, which is significantly lower than the original part's 36V maximum. It is not suitable for applications requiring supply voltages above 15V. Additionally, the minimum supply voltage of 3V does not meet the original part's 6V minimum requirement for all operating conditions.

Q: What is the impact of switching frequency differences between substitutes?

A: Switching frequency affects output ripple, EMI characteristics, and inductor/capacitor sizing. The original part operates at 1MHz. Substitutes with different frequencies (500kHz for LM3414 variants, 1.6MHz for LM3405) may require output filter component adjustments. Lower frequencies typically result in larger passive components; higher frequencies reduce component size but may increase EMI.

Q: Are all recommended substitutes ROHS3 compliant?

A: Yes, all parts listed in the parameter comparison table are ROHS3 compliant, meeting environmental and hazardous substance restrictions for EU and similar markets.
