MP2410GJ-P LED Driver IC Equivalent & Substitute Parts

Part Overview

The MP2410GJ-P is an active LED driver IC manufactured by Monolithic Power Systems Inc., designed for step-down (buck) topology DC-DC regulation with analog dimming control. This single-output regulator operates across a 4.2V to 24V supply range and delivers 2A output current, making it suitable for backlight applications. The device is packaged in TSOT-23-6 and maintains ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Substitute parts are necessary when the original part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for compatible alternatives with enhanced performance characteristics or broader operating ranges.

Substitute Part Grouping Explanation

Substitution eligibility for the MP2410GJ-P is determined by the following critical parameters: DC-DC regulator topology (step-down buck configuration), internal switching capability, single output channel, supply voltage compatibility (minimum 4.2V, maximum 24V overlap), output current rating (minimum 2A), dimming control method (analog or PWM capable), operating temperature range (-40°C to 125°C preferred), surface mount packaging, and ROHS3 compliance status.

Substitute parts are grouped into two categories:

Engineering Selection Recommendations

Direct Replacement (Identical Specifications): MP2410GJ-Z is the direct parametric equivalent, differing only in packaging format (Cut Tape & Digi-Reel versus Tape & Reel). Selection between MP2410GJ-P and MP2410GJ-Z depends on manufacturing process requirements and tape reel specifications. Both maintain ROHS3 compliance, MSL 1 rating, and identical electrical performance.

High-Current Applications (≥2A requirement): A6211GLJTR-T provides 3A output current with expanded voltage range (6V to 48V) and PWM dimming capability. This part is suitable when the design requires current headroom beyond 2A. Note the reduced operating temperature maximum (105°C versus 125°C) and MSL 3 rating. Automotive qualification (AEC-Q100 not listed for this part) should be verified if required.

Automotive-Qualified Alternatives: A6216KLPTR-T (Allegro, AEC-Q100 qualified) and LM3414SD/NOPB (Texas Instruments, automotive grade) both support -40°C to 125°C operating range with dual dimming modes. A6216KLPTR-T extends voltage range to 55V maximum. LM3414SD/NOPB operates at 500kHz frequency with 8-WSON package.

Compact Package Alternatives: AL8861WT-7 (Diodes, TSOT-25 package) and AL8861MP-13 (Diodes, 8-MSOP package) offer reduced footprint solutions with dual dimming capability. Both operate at 1MHz frequency. AL8861WT-7 has highest inventory availability (75,400 units). Current ratings are reduced (1A and 1.5A respectively) compared to MP2410GJ-P.

Extended Voltage Range: LM3404HVMA/NOPB (Texas Instruments) supports 6V to 75V supply range with 1A output current, suitable for high-voltage applications. Operating temperature range matches MP2410GJ-P (-40°C to 125°C). Automotive grade qualification applies.

Programmable Frequency Option: LT3474EFE-1#TRPBF (Analog Devices) provides programmable frequency range (200kHz to 2MHz) with 1A output current and automotive qualification. Supply range 4.6V to 36V. 16-TSSOP package provides additional pin count for enhanced functionality.

Alternative Topology (Boost Converter): LM3530UME-40B/NOPB represents a different topology (step-up/boost) suitable only for applications requiring voltage step-up from 2.7V to 5.5V input with 40V output. This part is not a direct substitute but may address specific backlight applications with lower input voltage requirements.

Lower Current Alternatives: IS31LT3350-V1SDLS2-TR (Lumissil, 650mA) and LM3414SD/NOPB (Texas Instruments, 1A) are suitable for designs where output current requirements are below 2A. Both support dual dimming modes and ROHS3 compliance.

All listed substitutes maintain ROHS3 compliance and REACH unaffected status. Selection should prioritize parts with MSL 1 rating for unlimited moisture sensitivity tolerance unless manufacturing environment supports higher MSL ratings.

Frequently Asked Questions (FAQ)

Q: Can MP2410GJ-Z be used as a direct replacement for MP2410GJ-P? A: Yes. MP2410GJ-Z is a parametric equivalent with identical electrical specifications (4.2V to 24V supply, 2A output, 1MHz frequency, analog dimming, -40°C to 125°C operating range). The difference is packaging format: MP2410GJ-P uses Tape & Reel while MP2410GJ-Z uses Cut Tape & Digi-Reel. Verify tape reel specifications match your manufacturing equipment requirements.

Q: What is the minimum output current requirement to eliminate certain substitutes? A: If your design requires exactly 2A output current, parts rated below 2A (AL8861WT-7 at 1A, AL8861MP-13 at 1.5A, IS31LT3350-V1SDLS2-TR at 650mA, LM3404HVMA/NOPB at 1A, LM3414SD/NOPB at 1A, LT3474EFE-1#TRPBF at 1A) are not suitable. Parts rated at or above 2A include MP2410GJ-P, MP2410GJ-Z, A6211GLJTR-T (3A), and A6216KLPTR-T (2A).

Q: Which substitutes support both analog and PWM dimming? A: A6216KLPTR-T, AL8861MP-13, AL8861WT-7, IS31LT3350-V1SDLS2-TR, and LM3414SD/NOPB all support both analog and PWM dimming modes. MP2410GJ-P and MP2410GJ-Z support analog dimming only. A6211GLJTR-T and LM3404HVMA/NOPB support PWM dimming only. LT3474EFE-1#TRPBF supports PWM dimming only.

Q: Are there automotive-qualified alternatives? A: Yes. A6216KLPTR-T (Allegro, AEC-Q100 qualified), LM3404HVMA/NOPB (Texas Instruments, automotive grade), LM3414SD/NOPB (Texas Instruments, automotive grade), and LT3474EFE-1#TRPBF (Analog Devices, automotive grade) all carry automotive qualifications. MP2410GJ-P does not list automotive qualification.

Q: What is the significance of MSL (Moisture Sensitivity Level) rating? A: MSL rating indicates moisture sensitivity during storage and handling. MSL 1 (unlimited) means no moisture precautions are required. MSL 2 (1 year) requires storage in dry conditions for up to one year. MSL 3 (168 hours) requires baking before reflow if exposed to moisture. MP2410GJ-P has MSL 1. A6216KLPTR-T has MSL 2. A6211GLJTR-T and IS31LT3350-V1SDLS2-TR have MSL 3. Select MSL 1 parts when manufacturing environment cannot support moisture control protocols.

Q: Can I use A6211GLJTR-T as a substitute if my design requires 2A output? A: A6211GLJTR-T is rated for 3A output current, which exceeds the 2A requirement. However, verify that the 8-SOIC-EP package footprint is compatible with your PCB layout, as it differs from the TSOT-23-6 package of MP2410GJ-P. Additionally, A6211GLJTR-T operates at -40°C to 105°C (versus -40°C to 125°C for MP2410GJ-P) and has MSL 3 rating.

Q: What is the difference between step-down (buck) and step-up (boost) topology? A: Step-down (buck) topology reduces input voltage to a lower output voltage, used in MP2410GJ-P and all listed substitutes except LM3530UME-40B/NOPB. Step-up (boost) topology increases input voltage to a higher output voltage. LM3530UME-40B/NOPB uses boost topology and is not a direct substitute for buck-based designs.

Q: Which substitute has the highest inventory availability? A: AL8861WT-7 (Diodes Incorporated) has the highest inventory with 75,400 units in stock. This part operates at 1A output current with 1MHz frequency and supports both analog and PWM dimming. Verify electrical specifications match your design requirements before selecting based on inventory availability.

Q: Can I substitute MP2410GJ-P with LM3530UME-40B/NOPB? A: No. LM3530UME-40B/NOPB uses step-up (boost) topology with 2.7V to 5.5V input range and 40V output, fundamentally different from MP2410GJ-P's step-down topology with 4.2V to 24V input range. This part is suitable only for applications requiring voltage step-up from lower input voltages.

Q: What supply voltage range is common across all substitutes? A: No single voltage range is common across all substitutes. The overlapping range where most substitutes operate is approximately 4.5V to 40V. However, MP2410GJ-P operates from 4.2V minimum, while some substitutes require 6V minimum. Verify your specific supply voltage requirements against each candidate part's minimum and maximum ratings.

Q: Which substitutes maintain the same operating temperature range as MP2410GJ-P? A: MP2410GJ-P operates from -40°C to 125°C. Parts maintaining this range are MP2410GJ-Z, A6216KLPTR-T, LM3404HVMA/NOPB, and LM3414SD/NOPB. All other substitutes have reduced maximum operating temperature (85°C to 105°C).
