Engineering Selection Recommendations
Tier 1 - Direct Manufacturer Replacements (Recommended for Pin-Compatible Designs):
AL8860QMP-13 and AL8861QMP-13 are the primary substitutes, both manufactured by Diodes Incorporated with identical 8-MSOP package and pinout compatibility. Both parts are active products with AEC-Q100 qualification and ROHS3 compliance. AL8860QMP-13 supports operating temperatures to 105°C and AL8861QMP-13 to 85°C, both lower than the original 125°C specification. Both offer enhanced current output (1.5A versus 1.3A) and expanded supply voltage range (4.5V to 40V versus 6V to 30V). AL8860QMP-13 provides higher inventory availability (125,400 units) compared to AL8861QMP-13 (75,200 units).
Tier 2 - Functional Equivalents with Enhanced Specifications:
LM3406HVQMHQ1 (Texas Instruments) provides the widest supply voltage range (6V to 75V) and highest operating temperature rating (-40°C to 150°C TJ), with 1.5A output current and PWM dimming. This part is AEC-Q100 qualified and ROHS3 compliant but requires a 14-HTSSOP package, necessitating PCB layout modification.
LT3474IFE-1#PBF (Analog Devices) offers the lowest minimum supply voltage (4.6V) and widest frequency range (200kHz to 2MHz), with 1A output current and PWM dimming in a 16-TSSOP package. This part is AEC-Q100 qualified and ROHS3 compliant but requires PCB redesign due to package change.
LM3414SD/NOPB (Texas Instruments) provides 1A output current with analog and PWM dimming capability in an 8-WFDFN package, supporting 4.5V to 42V supply range and -40°C to 125°C operating temperature. This part is ROHS3 compliant but lacks AEC-Q100 qualification.
A6216KLPTR-T (Allegro MicroSystems) delivers the highest current output (2A) and widest supply voltage range (4.5V to 55V) with analog and PWM dimming in a 16-TSSOP package. This part is AEC-Q100 qualified and ROHS3 compliant but requires PCB layout modification.
IS31LT3353-SDLS4-TR (Lumissil Microsystems) operates at 1A output current with analog and PWM dimming in a SOT-89-5 package, supporting 6V to 40V supply range and -40°C to 125°C operating temperature. This part is ROHS3 compliant but lacks automotive grade and AEC-Q100 qualification.
Selection Criteria Summary:
For designs requiring pin-compatible replacement with minimal PCB modification, select AL8860QMP-13 or AL8861QMP-13. For applications requiring extended supply voltage range or higher current capacity, evaluate LM3406HVQMHQ1 or A6216KLPTR-T with corresponding PCB redesign. For cost-optimized solutions where automotive qualification is not mandatory, consider LM3414SD/NOPB or IS31LT3353-SDLS4-TR. All recommended substitutes maintain step-down buck topology, single output configuration, PWM dimming capability, and surface mount construction.
Frequently Asked Questions (FAQ)
Q: Can AL8860QMP-13 or AL8861QMP-13 be used as direct pin-for-pin replacements for AL8807BQMP-13?
A: Yes. Both parts share identical 8-MSOP package with exposed pad and maintain the same pinout. No PCB layout modification is required. Both are active products with higher current ratings (1.5A versus 1.3A) and expanded supply voltage ranges (4.5V to 40V versus 6V to 30V).
Q: What is the primary difference between AL8860QMP-13 and AL8861QMP-13?
A: Both parts are functionally equivalent with identical electrical specifications. The primary difference is operating temperature range: AL8860QMP-13 operates to 105°C while AL8861QMP-13 operates to 85°C. AL8860QMP-13 has significantly higher inventory availability (125,400 units versus 75,200 units).
Q: Why do some substitute parts have different package types?
A: Package differences reflect design evolution and manufacturer standardization. LM3406HVQMHQ1 uses 14-HTSSOP, A6216KLPTR-T uses 16-TSSOP, LM3414SD/NOPB uses 8-WFDFN, and IS31LT3353-SDLS4-TR uses SOT-89-5. Package selection depends on application requirements for current capacity, thermal dissipation, and PCB real estate. Pin-compatible replacements (AL8860QMP-13, AL8861QMP-13) maintain the original 8-MSOP package.
Q: Are all substitute parts AEC-Q100 qualified?
A: No. AL8860QMP-13, AL8861QMP-13, LM3406HVQMHQ1, A6216KLPTR-T, and LT3474IFE-1#PBF are AEC-Q100 qualified. LM3414SD/NOPB and IS31LT3353-SDLS4-TR lack AEC-Q100 qualification. For automotive applications requiring AEC-Q100 compliance, select from the qualified parts.
Q: What is the impact of operating temperature differences between AL8807BQMP-13 and its substitutes?
A: AL8807BQMP-13 operates to 125°C (TJ). AL8860QMP-13 operates to 105°C (TA) and AL8861QMP-13 to 85°C (TA). LM3406HVQMHQ1 extends to 150°C (TJ), providing higher thermal margin. Temperature specifications use different measurement points (TJ = junction temperature, TA = ambient temperature), affecting thermal design calculations. Verify application thermal requirements before selection.
Q: Which substitute offers the highest current output capability?
A: A6216KLPTR-T delivers 2A output current, the highest among all substitutes. This part requires a 16-TSSOP package and PCB redesign but provides 53% higher current capacity than the original AL8807BQMP-13 (1.3A).
Q: Can I use IS31LT3353-SDLS4-TR in automotive applications?
A: IS31LT3353-SDLS4-TR lacks automotive grade designation and AEC-Q100 qualification. This part is suitable for non-automotive lighting applications. For automotive applications, select from AEC-Q100 qualified alternatives: AL8860QMP-13, AL8861QMP-13, LM3406HVQMHQ1, A6216KLPTR-T, or LT3474IFE-1#PBF.
Q: What supply voltage range considerations apply when selecting a substitute?
A: AL8807BQMP-13 operates from 6V to 30V. Substitutes offer expanded ranges: AL8860QMP-13 and AL8861QMP-13 (4.5V to 40V), LM3406HVQMHQ1 (6V to 75V), A6216KLPTR-T (4.5V to 55V), and LT3474IFE-1#PBF (4.6V to 36V). Select a substitute with supply voltage range encompassing your application requirements. Extended range capability provides design flexibility for future applications.
Q: Are all substitutes RoHS3 compliant?
A: Yes. All substitute parts listed are ROHS3 compliant, matching the original AL8807BQMP-13 compliance status.
