AL9910AS-13 Equivalent & Substitute Parts

Part Overview

The AL9910AS-13 is an LED Driver IC manufactured by Diodes Incorporated, classified as a Power Management (PMIC) component. This device functions as a 1-output AC DC offline switcher with step-down (buck) and step-up (boost) topology, featuring analog and PWM dimming capabilities. The part is designed for backlight, lighting, and signage applications and maintains active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design flexibility demands evaluation of functionally equivalent alternatives from different manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AL9910AS-13 is determined by the following critical parameters:

Primary Substitution Criteria:

• AC DC offline switcher topology with single output
• Operating temperature range: -40°C to 85°C
• Package type: 8-SOIC form factor (0.154", 3.90mm width)
• Surface mount mounting type
• ROHS3 compliance and MSL 1 rating
• Voltage supply capability within or exceeding 20V to 500V range
• PWM dimming functionality

Secondary Compatibility Factors:

• Frequency range overlap (25kHz to 300kHz preferred)
• Dimming method (PWM or Analog+PWM)
• Internal switch configuration (No internal switches)
• Active product status

Substitute parts are grouped by manufacturer and packaging variant. Parts meeting all primary criteria are considered parametric equivalents. Parts with reduced voltage supply minimums (below 20V) or different topology configurations (buck-only vs. buck/boost) represent functional alternatives with design trade-offs.

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalent (Highest Compatibility): AL9910S-13 from Diodes Incorporated is the closest parametric equivalent. Both parts share identical topology (buck/boost), dimming capability (analog and PWM), frequency range (25kHz to 300kHz), and package form factor (8-SOIC). The AL9910S-13 operates at a lower minimum supply voltage (15V vs. 20V), providing broader input range compatibility. Both maintain active product status, ROHS3 compliance, and MSL 1 rating. Selection between AL9910AS-13 and AL9910S-13 depends on packaging format availability (both available in Tape & Reel) and inventory requirements.

Manufacturer-Recommended Alternatives (IXYS CPC9909 Series): CPC9909N, CPC9909NE, and CPC9909NETR from IXYS Integrated Circuits Division maintain buck/boost topology and 8-SOIC package compatibility. These parts operate across a wider voltage range (8V to 550V) and support higher maximum supply voltage. Frequency range differs (30kHz to 120kHz vs. 25kHz to 300kHz). Dimming is PWM-only, eliminating analog dimming capability. Package variants include standard 8-SOIC (CPC9909N) and exposed pad versions (CPC9909NE, CPC9909NETR). Selection among these three depends on packaging format requirements: tube packaging (CPC9909N, CPC9909NE) or tape & reel format (CPC9909NETR).

Functional Alternatives (Topology Variation): MXHV9910B, MXHV9910BE, MXHV9910BETR, and MXHV9910BTR from IXYS Integrated Circuits Division and Littelfuse represent buck-only topology alternatives. These parts eliminate boost capability, operate at fixed 64kHz frequency, and support lower maximum supply voltage (450V vs. 500V). PWM dimming is supported; analog dimming is not available. Exposed pad variants (MXHV9910BE, MXHV9910BETR) provide enhanced thermal performance. Packaging formats include tube (MXHV9910B, MXHV9910BE), tape & reel (MXHV9910BETR), and cut tape & Digi-Reel (MXHV9910BTR). These alternatives are suitable only for applications that do not require boost topology or analog dimming functionality.

All substitute parts maintain active product status, ROHS3 compliance, and MSL 1 rating, ensuring regulatory and environmental compatibility with the original AL9910AS-13 specification.

Frequently Asked Questions (FAQ)

Q: Can AL9910S-13 be used as a direct replacement for AL9910AS-13? A: AL9910S-13 is a parametric equivalent with identical topology, dimming capability, and package form factor. The primary difference is minimum supply voltage (15V vs. 20V). Direct substitution is valid for applications where the 15V minimum supply voltage is acceptable. Both parts are available in tape & reel packaging and maintain identical compliance certifications.

Q: What is the key difference between AL9910AS-13 and CPC9909NETR? A: Both parts maintain 8-SOIC package compatibility and buck/boost topology. CPC9909NETR operates across a wider voltage range (8V to 550V) and features an exposed pad for improved thermal management. Frequency range differs (30kHz to 120kHz vs. 25kHz to 300kHz). CPC9909NETR supports PWM dimming only; analog dimming is not available. CPC9909NETR is manufactured by IXYS Integrated Circuits Division and supplied in tape & reel format.

Q: Why do MXHV9910 series parts have different topology than AL9910AS-13? A: MXHV9910 series parts implement buck-only topology, eliminating step-up (boost) capability. These parts are designed for applications requiring step-down conversion only. They operate at fixed 64kHz frequency and support lower maximum supply voltage (450V). Selection of MXHV9910 variants is appropriate only when boost topology is not required by the application design.

Q: What packaging format differences exist among substitute parts? A: Substitute parts are available in multiple packaging formats: tape & reel (AL9910AS-13, AL9910S-13, CPC9909NETR, MXHV9910BETR), tube (CPC9909N, CPC9909NE, MXHV9910B, MXHV9910BE), and cut tape & Digi-Reel (MXHV9910BTR). Packaging format selection depends on manufacturing process requirements and volume handling procedures. All formats maintain identical electrical performance and compliance certifications.

Q: Are exposed pad package variants (8-SOIC-EP) compatible with standard 8-SOIC PCB layouts? A: Exposed pad variants (CPC9909NE, CPC9909NETR, MXHV9910BE, MXHV9910BETR) feature additional thermal pad on the package underside. These parts are mechanically and electrically compatible with standard 8-SOIC PCB footprints. Exposed pad utilization is optional; thermal pad connection is not required for basic functionality. Exposed pad connection improves thermal performance in high-power applications.

Q: Which substitute part offers the widest voltage supply range? A: CPC9909N, CPC9909NE, and CPC9909NETR from IXYS Integrated Circuits Division support the widest voltage supply range (8V to 550V), compared to AL9910AS-13 (20V to 500V). These parts accommodate lower minimum input voltages and higher maximum supply voltages, providing greater design flexibility for diverse power supply architectures.

Q: Do all substitute parts maintain the same operating temperature range? A: All substitute parts listed maintain identical operating temperature range (-40°C to 85°C TA) and MSL 1 rating. Temperature performance and moisture sensitivity are consistent across all alternatives, ensuring compatibility with standard industrial and commercial application requirements.
