Engineering Selection Recommendations
Direct Parametric Equivalent: MP24895GQ-Z is the primary equivalent to MP24895GQ-P, offering identical electrical specifications, package form factor, and supply voltage range. Both devices are manufactured by Monolithic Power Systems Inc., maintain active product status, and are ROHS3 compliant. This part is suitable for direct substitution without circuit redesign.
Higher Current Capacity Alternatives: ILD6150XUMA1 (Infineon, 1.5A), A6216KLPTR-T (Allegro, 2A), and AL8861MP-13 (Diodes, 1.5A) provide increased output current capability while maintaining step-down buck topology and dual dimming modes (Analog/PWM). These parts are appropriate for applications requiring higher LED drive current or where design margin is desired. All three maintain active product status and ROHS3 compliance.
Compact Package Alternative: AL8861WT-7 (Diodes Incorporated, 1A) offers a smaller TSOT-25 package footprint compared to the 6-QFN form factor of the MP24895GQ-P. This part maintains active status, ROHS3 compliance, and dual dimming capability, making it suitable for space-constrained designs with reduced current requirements.
Automotive-Grade High-Voltage Option: LM3404HVMR/NOPB (Texas Instruments, 1A) supports extended supply voltage range (6V to 75V) with automotive-grade qualification. This part is appropriate for applications requiring higher input voltage tolerance, though it features PWM-only dimming without analog capability.
Obsolete Part Consideration: AL8807QMP-13 (Diodes Incorporated) carries obsolete product status and should not be selected for new designs. Existing inventory may be available, but long-term supply cannot be assured.
Limited Supply Voltage Range: LED2000DR and LED2000PUR (STMicroelectronics) operate within a narrower supply voltage range (3V to 18V) compared to the MP24895GQ-P (6V to 36V). These parts are suitable only for applications where input voltage remains within the 6V to 18V window and where PWM-only dimming is acceptable.
Frequently Asked Questions (FAQ)
Q: Can MP24895GQ-Z be used as a direct replacement for MP24895GQ-P? A: Yes. MP24895GQ-Z is a parametric equivalent manufactured by the same supplier with identical electrical specifications, package form factor (6-QFN 3x3), supply voltage range (6V to 36V), output current (700mA), and dimming modes (Analog, PWM). No circuit modifications are required.
Q: What is the primary difference between MP24895GQ-P and ILD6150XUMA1? A: ILD6150XUMA1 provides higher output current (1.5A versus 700mA) and extended operating temperature range (-40°C to 150°C TJ versus -40°C to 125°C TJ). The package differs (8-SOIC versus 6-QFN), requiring PCB layout modifications. Both support analog and PWM dimming and operate within overlapping supply voltage ranges (4.5V to 60V for ILD6150XUMA1 versus 6V to 36V for MP24895GQ-P).
Q: Is AL8861WT-7 suitable for applications requiring 700mA output current? A: AL8861WT-7 is rated for 1A maximum output current, which exceeds the 700mA requirement of the MP24895GQ-P. However, the TSOT-25 package is significantly smaller than the 6-QFN form factor, requiring PCB redesign. This part is appropriate only if space constraints justify the layout modification and the 1A rating provides adequate design margin.
Q: Why do LED2000DR and LED2000PUR have a narrower supply voltage range? A: LED2000DR and LED2000PUR are optimized for lower-voltage applications (3V to 18V input) and are not suitable for systems requiring the full 6V to 36V range of the MP24895GQ-P. Selection of these parts is limited to applications where input voltage remains within the 6V to 18V overlap window.
Q: Can I use LM3404HVMR/NOPB in place of MP24895GQ-P? A: LM3404HVMR/NOPB supports the required 6V minimum input voltage and provides automotive-grade qualification with extended high-voltage capability (up to 75V). However, this part features PWM-only dimming without analog dimming support. Substitution is appropriate only if the application does not require analog dimming functionality.
Q: What is the significance of "Not For New Designs" status on AL8807QMP-13? A: Parts marked "Not For New Designs" indicate that the manufacturer has discontinued active development and support. While existing inventory may be available, long-term supply cannot be assured. New designs should not incorporate this part; active alternatives such as AL8861MP-13 or ILD6150XUMA1 are recommended.
Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed in this reference maintain ROHS3 compliance, matching the environmental compliance status of the MP24895GQ-P.
Q: What package considerations apply when selecting a substitute? A: The MP24895GQ-P uses a 6-QFN (3x3) package. Substitutes with different packages (such as 8-SOIC, 8-MSOP-EP, TSOT-25, or 16-eTSSOP-EP) require PCB layout redesign, including trace routing, thermal management, and component placement modifications. Package selection should align with available PCB real estate and thermal dissipation requirements.
