Substitute Part Grouping Explanation

Substitute parts for the AL9910-5SP-13 are grouped into three categories based on parametric equivalence and manufacturer recommendations:

Parametric Equivalents (Same Manufacturer - Diodes Incorporated): AL9910ASP-13 and AL9910SP-13 share identical topology, dimming capabilities, package type, and compliance certifications. These parts differ only in packaging format (Cut Tape vs. Tape & Reel) and minimum supply voltage specification (20V vs. 15V for AL9910ASP-13). Both maintain the same 8-SOIC exposed pad package and frequency range.

Manufacturer Recommended Alternatives (IXYS & Microchip): CPC9909 series (CPC9909N, CPC9909NE, CPC9909NETR) and HV9910 series (HV9910CLG-G, HV9910CSG-G) are functionally equivalent AC DC offline switchers with PWM dimming. These parts operate within compatible voltage ranges (8V-550V for CPC9909; 15V-450V for HV9910) and maintain surface mount 8-SOIC packaging. Frequency ranges differ (30kHz-120kHz for CPC9909; 25kHz/100kHz for HV9910).

Cross-Topology Alternatives: HV9921N3-G (Microchip) and MP4068GS-Z (Monolithic Power Systems) represent alternative topologies. HV9921N3-G uses through-hole TO-92-3 packaging with triac dimming and 20mA output current. MP4068GS-Z operates at lower voltage ranges (4.1V-5V) with triac dimming and 160mA output current, suitable for different application requirements.

Engineering Selection Recommendations

Direct Parametric Equivalents: AL9910SP-13 is the primary equivalent, maintaining identical electrical specifications, topology, dimming modes, and temperature range while differing only in packaging format (Tape & Reel). AL9910ASP-13 is functionally equivalent with a higher minimum supply voltage specification (20V vs. 15V), suitable for applications where input voltage exceeds 20V.

Manufacturer Recommended Alternatives: CPC9909NETR (IXYS) and HV9910CSG-G (Microchip) are qualified substitutes for applications requiring AC DC offline switching with PWM dimming. CPC9909NETR extends the maximum supply voltage to 550V and operates at lower minimum voltage (8V). HV9910CSG-G operates as a DC DC controller with extended temperature range (-40°C to 125°C) and supports both analog and PWM dimming. Both maintain 8-SOIC surface mount packaging and ROHS3 compliance.

Cross-Topology Alternatives: HV9921N3-G is suitable only for applications requiring through-hole mounting and triac dimming with 20mA output current specification. MP4068GS-Z operates at significantly lower voltage ranges (4.1V-5V output, 50V specified) and is applicable only to low-voltage lighting applications with triac dimming requirements. All substitute parts maintain ROHS3 compliance and MSL 1 rating except MP4068GS-Z (MSL 2).

Frequently Asked Questions (FAQ)

Q: Can AL9910SP-13 replace AL9910-5SP-13 directly? A: Yes. AL9910SP-13 is a parametric equivalent with identical electrical specifications, topology, dimming capabilities, and temperature range. The only difference is packaging format (Tape & Reel vs. the original Tape & Reel designation). Both use 8-SOIC exposed pad surface mount packages.

Q: What is the key difference between AL9910ASP-13 and AL9910-5SP-13? A: AL9910ASP-13 specifies a minimum supply voltage of 20V compared to 15V for AL9910-5SP-13. This part is suitable for applications where input voltage is guaranteed to exceed 20V. Packaging differs (Cut Tape & Digi-Reel vs. Tape & Reel).

Q: Are CPC9909 series parts compatible with AL9910-5SP-13? A: CPC9909 series parts (CPC9909N, CPC9909NE, CPC9909NETR) are functionally compatible AC DC offline switchers with similar topology and surface mount 8-SOIC packaging. Key differences include lower minimum supply voltage (8V vs. 15V), higher maximum supply voltage (550V vs. 500V), and PWM-only dimming (no analog dimming). Operating temperature range is -40°C to 85°C.

Q: What are the limitations of HV9910CSG-G as a substitute? A: HV9910CSG-G operates as a DC DC controller rather than an AC DC offline switcher, limiting its application scope. Maximum supply voltage is 450V (vs. 500V). However, it offers extended operating temperature range (-40°C to 125°C) and supports both analog and PWM dimming.

Q: When should HV9921N3-G be considered? A: HV9921N3-G is applicable only to applications requiring through-hole mounting (TO-92-3 package) and triac dimming with 20mA output current specification. It is not suitable for surface mount applications or designs requiring analog dimming.

Q: Is MP4068GS-Z a suitable substitute? A: MP4068GS-Z is applicable only to low-voltage lighting applications with supply voltage range of 4.1V to 5V and 50V output specification. It is not suitable for high-voltage offline switching applications. Triac dimming and 160mA output current are specified. MSL rating is 2 (1 Year) vs. MSL 1 for the primary part.

Q: What packaging options are available for AL9910-5SP-13 equivalents? A: Diodes Incorporated offers AL9910-5SP-13 in Tape & Reel (TR) packaging and AL9910ASP-13 in Cut Tape (CT) & Digi-Reel format. Both use 8-SOIC (0.154", 3.90mm Width) exposed pad surface mount packages. IXYS and Microchip alternatives also use 8-SOIC surface mount packages in various packaging formats (Tube, Tape & Reel, Cut Tape).

Q: Are all substitute parts ROHS3 compliant? A: Yes, all listed substitute parts maintain ROHS3 compliance. MP4068GS-Z has MSL 2 (1 Year) rating vs. MSL 1 (Unlimited) for other parts, which may affect storage and handling requirements.
