Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AL9910-5S-13 are grouped based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) form factor
• Number of Outputs: 1 output configuration
• Dimming Control: Analog and/or PWM capability
• Voltage Supply Range: Minimum 15V to maximum 450V or higher
• Frequency Range: Operating within or overlapping 25kHz to 300kHz
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant
• Product Status: Active or equivalent lifecycle status

Substitution Categories:

Parametric Equivalent (Same Manufacturer): AL9910S-13 differs only in packaging format (Tape & Reel vs. Cut Tape), maintaining identical electrical specifications and topology.

Manufacturer Recommended Equivalents (IXYS): CPC9909N, CPC9909NE, and CPC9909NETR share the same 8-SOIC package, AC DC offline switcher topology, and PWM dimming capability. Voltage supply range extends to 550V maximum. Frequency range is 30kHz to 120kHz. These parts are suitable where the narrower frequency range and extended voltage ceiling are compatible with application requirements.

Manufacturer Recommended Equivalents (Microchip): HV9910CLG-G and HV9910CSG-G operate as DC DC controllers with step-down (buck) topology only, supporting both analog and PWM dimming. Voltage supply range is 15V to 450V. Frequency options are 25kHz or 100kHz. These parts are applicable where boost topology is not required.

Limited Compatibility Substitute (Texas Instruments): TPS92002D is an AC DC offline switcher with flyback and step-down topologies, supporting triac dimming only. Maximum supply voltage is 21V with fixed 5V output. This part has restricted applicability due to different dimming method and lower voltage rating. Product status is Last Time Buy.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Highest Compatibility): AL9910S-13 is the primary substitute, offering identical electrical and functional specifications. The only difference is packaging format (Tape & Reel vs. Cut Tape). Both parts are Active status and ROHS3 compliant. Selection between these two depends solely on procurement and assembly requirements.

Cross-Manufacturer Substitutes (Conditional): CPC9909NETR (IXYS) and HV9910CSG-G (Microchip) are suitable substitutes when the following conditions are met:

• Application does not require the full 25kHz to 300kHz frequency range; narrower ranges (30kHz-120kHz or 25kHz/100kHz fixed) are acceptable
• For CPC9909NETR: Boost topology is required; analog dimming is not required (PWM only)
• For HV9910CSG-G: Boost topology is not required; step-down (buck) control is sufficient
• Supply voltage requirements fall within the specified ranges (8V-550V for CPC9909NETR; 15V-450V for HV9910CSG-G)

All three cross-manufacturer options are Active status and ROHS3 compliant.

Limited Use Substitute: TPS92002D (Texas Instruments) is not recommended as a primary substitute due to Last Time Buy status, restricted voltage range (maximum 21V), fixed 5V output, and triac-only dimming incompatibility with analog/PWM requirements. Use only when application-specific constraints mandate this topology and dimming method.

Frequently Asked Questions (FAQ)

Q: Can AL9910S-13 be used as a direct replacement for AL9910-5S-13? A: Yes. Both parts are manufactured by Diodes Incorporated with identical electrical specifications, topology, and functional capabilities. The difference is packaging format: AL9910-5S-13 is supplied in Cut Tape (CT) & Digi-Reel format, while AL9910S-13 is supplied in Tape & Reel (TR) format. Selection depends on assembly line requirements and procurement preferences.

Q: What are the key differences between the Diodes AL9910 series and the IXYS CPC9909 series? A: Both are AC DC offline switchers with buck and boost topologies in 8-SOIC packages. Key differences: CPC9909 series has a lower minimum supply voltage (8V vs. 15V), higher maximum supply voltage (550V vs. 500V), narrower frequency range (30kHz-120kHz vs. 25kHz-300kHz), and PWM-only dimming (no analog dimming). CPC9909 series is suitable for applications not requiring analog dimming and operating within the specified frequency range.

Q: Can HV9910CSG-G replace AL9910-5S-13 in all applications? A: No. HV9910CSG-G is a DC DC controller with step-down (buck) topology only, lacking the boost capability of AL9910-5S-13. It is suitable only for applications requiring buck topology. Both support analog and PWM dimming and operate within overlapping voltage ranges (15V-450V). Operating temperature range is higher for HV9910CSG-G (-40°C to 125°C junction temperature vs. -40°C to 85°C ambient for AL9910-5S-13).

Q: Why is TPS92002D listed as a substitute if it has significant differences? A: TPS92002D is included as a limited-compatibility option for specific applications requiring triac dimming control and operating at supply voltages below 21V with 5V output. It is not a general-purpose substitute. The Last Time Buy status indicates this part is being discontinued and should not be selected for new designs unless legacy compatibility is required.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All parts listed—AL9910S-13, CPC9909NETR, HV9910CSG-G, and TPS92002D—are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level and REACH Unaffected status.

Q: What is the significance of the exposed pad (EP) in CPC9909NE and HV9910CSG-G packages? A: The exposed pad variant (8-SOIC-EP) provides enhanced thermal dissipation compared to standard 8-SOIC packages. This is beneficial in high-power applications where heat management is critical. Pin compatibility remains identical; PCB layout must accommodate the exposed pad for thermal performance benefits.

Q: Can frequency range differences affect application performance? A: Yes. AL9910-5S-13 operates across 25kHz to 300kHz, providing flexibility for various EMI filtering and transformer design requirements. CPC9909NETR is limited to 30kHz-120kHz, and HV9910CSG-G offers fixed frequencies (25kHz or 100kHz). Application-specific frequency requirements must be verified before substitution to ensure compatibility with power supply design and EMI specifications.
