Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP3302AW6-7 is determined by alignment of the following critical parameters:

Functional Equivalence Criteria:

• Manufacturer: Diodes Incorporated (same manufacturer ensures design continuity)
• Category: Power Management (PMIC)
• Topology: Flyback converter architecture
• Output Isolation: Isolated configuration
• Voltage - Supply Range: 10V ~ 28V compatibility
• Switching Frequency: 120kHz operation
• Fault Protection: Current Limiting, Overload, Overvoltage, Overtemperature protection
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount
• Compliance: RoHS and REACH status alignment

The AP3303S9-13 qualifies as a substitute based on shared manufacturer origin, identical supply voltage range, matching operating temperature specifications, surface mount configuration, and equivalent compliance certifications. Both devices are designed for AC-DC power conversion applications with integrated protection mechanisms.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The AP3302AW6-7 is classified as obsolete, making the AP3303S9-13 the appropriate selection for new designs and production continuity. The AP3303S9-13 maintains active product status with Diodes Incorporated, ensuring long-term availability and supply chain stability.

Compliance Alignment: Both devices maintain REACH Unaffected status and RoHS compliance certifications. The AP3303S9-13 carries ROHS3 Compliant designation, representing current regulatory alignment. Both parts are classified under identical HTSUS and ECCN codes (8542.39.0001 and EAR99 respectively), confirming regulatory equivalence.

Electrical Parameter Alignment: The substitute part maintains identical supply voltage specifications (10V ~ 28V) and operating temperature range (-40°C ~ 85°C TA), ensuring functional compatibility in equivalent circuit topologies. Both devices are designed for AC-DC power conversion applications with integrated protection mechanisms.

Package Consideration: The AP3302AW6-7 uses SOT-26 packaging while the AP3303S9-13 uses 9-SSOP packaging. PCB layout modifications are required to accommodate the different package footprints and pin configurations. Pin-to-pin functional mapping must be verified during design transition.

Frequently Asked Questions (FAQ)

Q: Can the AP3303S9-13 directly replace the AP3302AW6-7 without circuit modifications?

A: The AP3303S9-13 provides electrical functional equivalence in terms of supply voltage range, operating temperature, and protection features. However, package differences (SOT-26 versus 9-SSOP) require PCB layout redesign and pin configuration verification. Schematic review is necessary to confirm pin-to-pin compatibility.

Q: What is the significance of the obsolete status for the AP3302AW6-7?

A: Obsolete classification indicates that Diodes Incorporated has discontinued production and support for this device. The AP3303S9-13, with active product status, ensures continued availability, technical support, and supply chain access for new production runs and design implementations.

Q: Are there compliance differences between the two parts?

A: Both parts maintain REACH Unaffected status and RoHS compliance. The AP3303S9-13 carries ROHS3 Compliant designation, representing alignment with current regulatory standards. Both devices share identical HTSUS and ECCN classifications, confirming regulatory equivalence for import and export purposes.

Q: What is the impact of different Moisture Sensitivity Levels (MSL)?

A: The AP3302AW6-7 has MSL 1 (Unlimited), while the AP3303S9-13 has MSL 3 (168 Hours). MSL 3 requires controlled storage conditions and limits shelf life to 168 hours after moisture exposure. Handling procedures and storage protocols must be adjusted accordingly for the substitute part.

Q: How do the package differences affect component selection?

A: The AP3302AW6-7 uses SOT-26 (6-lead) packaging while the AP3303S9-13 uses 9-SSOP (9-lead) packaging. These different form factors require distinct PCB footprints, trace routing, and assembly processes. Design teams must verify pin functionality mapping and validate thermal management characteristics for the new package configuration.

Q: Are both parts suitable for the same application categories?

A: Both devices are designed for AC-DC power conversion applications, including switching adapters and charger circuits. The AP3303S9-13 is specifically documented for AC-DC adapter and charger applications. Functional equivalence in topology and electrical specifications supports application compatibility, subject to circuit-level validation.
