Engineering Selection Recommendations

Direct Current-Matched Substitute:

TLD5045EJXUMA1 (Infineon LITIX™ series) matches the MP24895GJ-P at 700mA output current with identical dimming capability (Analog + PWM). This part operates across 5V to 40V supply range, automotive grade qualification, and -40°C to 150°C temperature range. Package differs (8-SOIC-EP vs. TSOT-23-5), requiring PCB layout modification. Suitable for applications where package footprint change is acceptable.

Higher Current Alternatives with Extended Voltage Range:

LT3932IUFD#PBF (Analog Devices) and MAX20051AUD/V+ (Analog Devices/Maxim) both deliver 2A output current with dual dimming modes. These parts support the full 6V to 36V supply window of the MP24895GJ-P with extended upper limits (36V and 65V respectively). Both maintain automotive grade status and -40°C to 125°C operating range. Larger packages (28-QFN and 14-TSSOP-EP) accommodate higher current handling.

PWM-Only Alternatives:

LT3474IFE-1#PBF (Analog Devices) and LM3404MA/NOPB (Texas Instruments) provide 1A output current with PWM dimming only. Both support 6V minimum input and automotive qualification. These are suitable where analog dimming is not required.

Dual Dimming Mode Alternatives:

LM3414MRX/NOPB (Texas Instruments) delivers 1A with analog and PWM dimming across 4.5V to 42V supply range, automotive grade, in 8-SO PowerPad package.

All substitute parts maintain ROHS3 compliance and active product status, ensuring long-term availability and regulatory alignment with the original MP24895GJ-P.

Frequently Asked Questions (FAQ)

Q: Can LT3590EDC#TRMPBF replace MP24895GJ-P in a 700mA application?

A: LT3590EDC#TRMPBF is rated for 80mA output current, which is insufficient for applications requiring 700mA. This part is not suitable as a direct substitute for the MP24895GJ-P.

Q: What is the key difference between TLD5045EJXUMA1 and MP24895GJ-P?

A: Both devices deliver 700mA with step-down topology and dual dimming modes (Analog + PWM). The primary differences are package type (8-SOIC-EP vs. TSOT-23-5), maximum supply voltage (40V vs. 36V), and maximum operating temperature (150°C vs. 125°C). TLD5045EJXUMA1 is suitable for designs where the larger package footprint is acceptable.

Q: Are higher current parts like LT3932IUFD#PBF backward compatible with MP24895GJ-P?

A: LT3932IUFD#PBF (2A) can substitute for MP24895GJ-P (700mA) in terms of functional capability, as it supports the same supply voltage range (3.6V to 36V), dual dimming modes, and automotive qualification. However, the larger 28-QFN package requires PCB redesign. Circuit design must account for the higher current rating and different pin configuration.

Q: Which substitute parts support both analog and PWM dimming like the MP24895GJ-P?

A: TLD5045EJXUMA1, LM3414MRX/NOPB, LT3932IUFD#PBF, and MAX20051AUD/V+ all support both analog and PWM dimming modes, matching the MP24895GJ-P dimming capability.

Q: What is the impact of package change when substituting the MP24895GJ-P?

A: The MP24895GJ-P uses TSOT-23-5 (5-pin small outline), while most substitutes use larger packages (8-SOIC, 14-TSSOP, 16-TSSOP, 28-QFN, or 6-DFN). Larger packages require modified PCB layouts, increased board space, and updated thermal management considerations. Pin assignments must be verified against the substitute datasheet before implementation.

Q: Is automotive grade qualification required for all substitute parts?

A: Automotive grade qualification is specified for MP24895GJ-P and is present in most recommended substitutes (TLD5045EJXUMA1, LT3474IFE-1#PBF, LM3404MA/NOPB, LM3414MRX/NOPB, LT3932IUFD#PBF). MAX20051AUD/V+ does not list automotive grade but is ROHS3 compliant and active. Application requirements determine whether automotive qualification is mandatory.

Q: Can LT3474IFE-1#PBF be used if only PWM dimming is needed?

A: Yes. LT3474IFE-1#PBF supports PWM dimming across 4.6V to 36V supply range with 1A output current and automotive grade qualification. It is suitable for applications where analog dimming is not required, though it delivers higher current (1A vs. 700mA) than the MP24895GJ-P.
