AL9910A-5S-13 Equivalent & Substitute Parts

Part Overview

The AL9910A-5S-13 is an LED Driver IC manufactured by Diodes Incorporated, designed for AC DC offline switching applications. This device functions as a 1-output switcher supporting both step-down (buck) and step-up (boost) topologies with analog and PWM dimming capabilities. The part is actively produced and widely used in backlight, lighting, and signage applications. Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical parameters of this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AL9910A-5S-13 are identified based on the following critical parameters that define functional equivalence within LED driver IC applications:

• Type & Topology: AC DC offline switcher with step-down (buck) and step-up (boost) capability
• Number of Outputs: Single output configuration
• Package & Mounting: 8-SOIC surface mount package with 0.154" (3.90mm) width
• Supply Voltage Range: Operating within or overlapping the 20V–500V input specification
• Dimming Capability: Support for analog and/or PWM dimming methods
• Compliance: ROHS3 compliance and active product status

The MP4068GS from Monolithic Power Systems is identified as a substitute based on matching package type, surface mount configuration, single-output topology, and AC DC offline switcher classification. Both devices support step-down and step-up topologies and are actively produced with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the AL9910A-5S-13 and MP4068GS are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. Selection between these devices depends on application-specific requirements within the defined electrical operating ranges. The AL9910A-5S-13 operates across a wider supply voltage range (20V–500V) with analog and PWM dimming support. The MP4068GS operates within a narrower supply voltage range (4.1V–5V) with triac dimming capability and specified output current of 160mA at 50V output.

Frequently Asked Questions (FAQ)

Q: Can the MP4068GS directly replace the AL9910A-5S-13 in all applications?

A: Direct replacement depends on application requirements. Both devices share the same 8-SOIC package and surface mount configuration. However, the MP4068GS operates at significantly lower supply voltages (4.1V–5V maximum) compared to the AL9910A-5S-13 (20V–500V maximum). Applications requiring high-voltage input operation cannot use the MP4068GS as a substitute.

Q: What are the key differences in dimming capability?

A: The AL9910A-5S-13 supports analog and PWM dimming methods. The MP4068GS supports triac dimming. Applications requiring specific dimming control methods must verify compatibility with the substitute device's dimming topology.

Q: Are both devices pin-compatible?

A: Both devices use the 8-SOIC package with 0.154" (3.90mm) width. The MP4068GS is specified as 8-SOIC-7A (7 leads), while the AL9910A-5S-13 uses standard 8-SO packaging. Physical package compatibility does not guarantee functional pin compatibility; circuit design verification is required.

Q: What compliance certifications apply to both parts?

A: Both the AL9910A-5S-13 and MP4068GS are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001.

Q: How do the operating frequencies compare?

A: The AL9910A-5S-13 operates at 300kHz, while the MP4068GS operates at 22kHz. This difference may affect circuit design considerations including inductor selection, capacitor ripple current ratings, and EMI characteristics.
