UCC28811DR LED Driver IC Equivalent & Substitute Parts

Part Overview

The UCC28811DR is an active LED driver IC manufactured by Texas Instruments, designed for offline AC/DC switching applications with Triac dimming capability. This 8-SOIC surface mount component functions as a single-output power management IC suitable for lighting applications. The part is currently in active production status with 35,634 units in stock inventory.

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to supply constraints, manufacturing discontinuation, or application-specific performance needs. Substitute parts must maintain compatibility across critical electrical parameters including supply voltage range, output topology, dimming methodology, and thermal operating specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UCC28811DR are qualified based on the following critical parameters that determine functional interchangeability:

Primary Substitution Criteria:

• Category: Power Management (PMIC)
• Type: AC DC Offline Switcher
• Number of Outputs: 1
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Secondary Compatibility Parameters:

• Topology: Must support Step-Down (Buck) and Step-Up (Boost) configurations
• Applications: Lighting
• Operating Temperature Range: Minimum -40°C lower bound
• Package compatibility: 8-pin surface mount configurations

Two qualified substitute parts are identified: AL9910-5SP-13 (Diodes Incorporated) and MP4054AGJ-Z (Monolithic Power Systems). Both parts satisfy the core substitution criteria while maintaining compliance with RoHS3 and active production status.

Parameter Comparison

Engineering Selection Recommendations

AL9910-5SP-13 (Diodes Incorporated): This substitute maintains 8-SOIC package compatibility with an exposed pad variant. The part supports extended maximum supply voltage (500V) and offers dual dimming capability (Analog and PWM) compared to the Triac-only dimming of the UCC28811DR. Operating temperature range matches the primary part at -40°C to 105°C. This part is suitable for applications requiring flexible dimming control beyond Triac functionality. ROHS3 compliance and active production status are confirmed.

MP4054AGJ-Z (Monolithic Power Systems): This substitute uses a different package form factor (SOT-23-8 Thin) and therefore requires PCB layout modification. The part operates within a narrower supply voltage range (12V to 28V) and provides PWM dimming only. Operating temperature extends to 125°C junction temperature, offering improved thermal performance. This part is suitable for applications with constrained PCB space and PWM dimming requirements. ROHS3 compliance and active production status are confirmed.

Selection Basis: Both substitute parts maintain active production status and ROHS3 compliance. Package selection between AL9910-5SP-13 and MP4054AGJ-Z depends on PCB layout constraints and dimming control methodology requirements. The AL9910-5SP-13 preserves the 8-SOIC footprint, while MP4054AGJ-Z requires layout redesign but offers compact SOT-23-8 form factor.

Frequently Asked Questions (FAQ)

Q: Can AL9910-5SP-13 directly replace UCC28811DR without PCB modification? A: Yes. Both parts use 8-SOIC package with 0.154" width and 3.90mm dimensions. The AL9910-5SP-13 includes an exposed pad variant, which may require additional PCB pad design but maintains pin-to-pin compatibility.

Q: What is the primary difference in dimming capability between these parts? A: The UCC28811DR supports Triac dimming only. The AL9910-5SP-13 supports both Analog and PWM dimming. The MP4054AGJ-Z supports PWM dimming only. Application circuits must be designed to accommodate the specific dimming methodology of the selected part.

Q: Does MP4054AGJ-Z require PCB redesign? A: Yes. The MP4054AGJ-Z uses SOT-23-8 Thin package, which differs from the 8-SOIC footprint of the UCC28811DR. PCB layout modification is required for this substitution.

Q: Are all three parts RoHS3 compliant? A: Yes. UCC28811DR, AL9910-5SP-13, and MP4054AGJ-Z are all ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: What is the maximum operating temperature difference? A: The UCC28811DR and AL9910-5SP-13 operate to 105°C (TA). The MP4054AGJ-Z operates to 125°C (TJ), providing 20°C additional thermal margin.

Q: Are all parts currently in active production? A: Yes. All three parts maintain active product status with confirmed inventory availability.

Q: What supply voltage range must be considered for substitution? A: The UCC28811DR maximum is 18V. The AL9910-5SP-13 supports up to 500V. The MP4054AGJ-Z supports up to 28V. Application circuit design must ensure the selected part operates within its specified voltage range.
