Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP3313GC-P are selected based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Topology: Step-Up (Boost) DC DC Regulator configuration
• Output Configuration: 3-output LED driver architecture
• Supply Voltage Range: Minimum 2.7V to 5.5V compatibility window
• Dimming Capability: Support for PWM, I2C, or Analog control methods
• Thermal Range: Operating temperature span of -40°C to 125°C or better
• Product Status: Active manufacturing status
• Compliance: ROHS3 and REACH compliance alignment

The four identified substitute parts (TPS61310YFFR, TPS61311YFFR, MAX8834YEWP+T, and LT3492EUFD#PBF) each satisfy the core functional requirements of LED driver operation with 3-output configuration and Step-Up topology. Variations in package format, current capacity, and frequency response represent design trade-offs suitable for different application constraints while maintaining core LED driver functionality.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status with ROHS3 compliance and REACH unaffected designation, ensuring regulatory alignment with the MP3313GC-P across automotive, industrial, and consumer applications.

TPS61310YFFR and TPS61311YFFR (Texas Instruments): These parts provide Step-Up topology with 3-output configuration and PWM dimming capability. Both operate within the 2.5V to 5.5V supply window and support backlight and camera flash applications. Operating temperature range extends to 85°C (TA), which is lower than the MP3313GC-P junction temperature specification. Package format is 20-DSBGA, larger than the MP3313GC-P 12-WLCSP. Current capacity reaches 1.5A (Flash), exceeding the MP3313GC-P 25mA specification. Frequency operation at 2MHz and 1.92MHz respectively provides higher switching rates than the MP3313GC-P range.

MAX8834YEWP+T (Analog Devices/Maxim Integrated): This part delivers Step-Up topology with 3-output configuration and I2C dimming control. Supply voltage range spans 2.5V to 5.5V, matching the MP3313GC-P lower bound. Output voltage specification of 3.7V to 5.2V differs from the MP3313GC-P 38V output. Current capacity includes 16mA standard operation with 750mA flash capability. Operating temperature range is -40°C to 85°C (TA). Package format is 20-WLP, representing a different footprint from the MP3313GC-P. Applications include backlight and camera flash.

LT3492EUFD#PBF (Analog Devices): This part supports multiple topologies including SEPIC, Step-Down (Buck), and Step-Up (Boost) with 3-output configuration. Supply voltage range extends to 30V maximum, providing broader input compatibility. PWM dimming is supported. Operating temperature range reaches -40°C to 125°C (TJ), matching the MP3313GC-P thermal specification. Package format is 28-QFN (4x5), larger than the MP3313GC-P 12-WLCSP. Current capacity is specified as 600mA (Switch), significantly exceeding the MP3313GC-P 25mA per channel.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the MP3313GC-P?

A: Substitution eligibility is based on matching the core functional architecture: 3-output LED driver with Step-Up (Boost) topology, supply voltage compatibility within the 2.7V to 5.5V range, and support for dimming control methods (PWM, I2C, or Analog). All substitute parts listed meet these criteria while maintaining active product status and ROHS3 compliance.

Q: Can I use TPS61310YFFR or TPS61311YFFR as direct replacements?

A: These Texas Instruments parts provide Step-Up topology with 3-output configuration and PWM dimming, satisfying core functional requirements. However, the 20-DSBGA package differs from the MP3313GC-P 12-WLCSP footprint, requiring PCB layout modification. Operating temperature maximum of 85°C (TA) is lower than the MP3313GC-P 125°C (TJ) specification. Current capacity of 1.5A (Flash) exceeds the MP3313GC-P 25mA per channel.

Q: What are the key differences between MAX8834YEWP+T and the MP3313GC-P?

A: The MAX8834YEWP+T uses I2C dimming control instead of the MP3313GC-P's Analog/I2C/PWM options. Output voltage is specified as 3.7V to 5.2V rather than 38V. The 20-WLP package differs from the 12-WLCSP footprint. Operating temperature range is -40°C to 85°C (TA), lower than the MP3313GC-P. Current capacity is 16mA standard with 750mA flash capability.

Q: Why does LT3492EUFD#PBF support multiple topologies?

A: The LT3492EUFD#PBF is designed as a flexible LED driver IC capable of SEPIC, Step-Down (Buck), and Step-Up (Boost) configurations. This multi-topology approach allows a single part number to address diverse application requirements. For MP3313GC-P substitution, the Step-Up (Boost) mode with 3-output configuration applies. The 28-QFN package is larger than the MP3313GC-P 12-WLCSP, and current capacity of 600mA (Switch) significantly exceeds the 25mA per channel specification.

Q: Are all substitute parts available in the same packaging?

A: No. The MP3313GC-P uses 12-WLCSP (1.3x1.7) packaging. Substitute parts use different formats: TPS61310YFFR and TPS61311YFFR use 20-DSBGA, MAX8834YEWP+T uses 20-WLP, and LT3492EUFD#PBF uses 28-QFN (4x5). PCB layout and footprint modifications are required for any substitution.

Q: Do all substitute parts support the same dimming methods?

A: No. The MP3313GC-P supports Analog, I2C, and PWM dimming. TPS61310YFFR and TPS61311YFFR support PWM only. MAX8834YEWP+T supports I2C only. LT3492EUFD#PBF supports PWM only. Application firmware and control circuitry must be evaluated for compatibility with the selected substitute part's dimming capabilities.

Q: What is the inventory status of these substitute parts?

A: Current inventory levels are: MP3313GC-P (1036 pcs), TPS61310YFFR (12300 pcs), TPS61311YFFR (1900 pcs), MAX8834YEWP+T (10200 pcs), and LT3492EUFD#PBF (2400 pcs). All parts are listed as new original stock.
