Substitute Part Grouping Explanation
Substitution of the AP9101CAK-AETRG1 is determined by the following criteria:
Primary Substitution Criteria:
- Identical manufacturer (Diodes Incorporated)
- Identical base product number (AP9101)
- Identical function (Battery Protection)
- Identical battery chemistry (Lithium Ion/Polymer)
- Identical number of cells (1)
- Identical fault protection capabilities (Over Current, Over Voltage)
- Identical operating temperature range (-40°C ~ 85°C)
- Identical mounting type (Surface Mount)
- Identical package type (SOT-25 / SC-74A, SOT-753)
- Identical compliance certifications (ROHS3, REACH Unaffected)
Packaging Variants: Substitute parts differ only in packaging format (Tape & Reel, Cut Tape, or Cut Tape & Digi-Reel®), which affects handling and supply chain logistics but not electrical or mechanical performance.
Cross-Manufacturer Substitution: The S-8241ABKMC-GBKT2G from ABLIC Inc. is a parametric equivalent with identical electrical specifications and operating characteristics, though it uses SOT-23-5 packaging instead of SOT-25.

Engineering Selection Recommendations
Diodes Incorporated AP9101 Series (Same Manufacturer): All AP9101 variants from Diodes Incorporated are electrically and mechanically equivalent to the AP9101CAK-AETRG1. Selection among these parts should be based on packaging availability and supply chain requirements. The primary part (AP9101CAK-AETRG1) maintains Active product status, making it the preferred choice for new designs. Obsolete variants remain functionally compatible but should be used only when the Active part is unavailable.
Cross-Manufacturer Alternative (ABLIC Inc.): The S-8241ABKMC-GBKT2G provides parametric equivalence with identical electrical specifications and operating characteristics. However, this part carries "Not For New Designs" status and uses SOT-23-5 packaging instead of SOT-25. PCB layout modifications are required to accommodate the different package footprint. This option is suitable only for legacy designs or when Diodes Incorporated parts are unavailable.
Compliance Considerations: All listed substitutes maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility across all options.
Frequently Asked Questions (FAQ)
Q: Can I substitute AP9101CAK-AETRG1 with any other AP9101 variant? A: Yes. All AP9101 variants share identical electrical specifications, battery chemistry support, fault protection capabilities, and operating temperature range. Differences exist only in packaging format (Tape & Reel, Cut Tape, or Digi-Reel®), which affects supply chain handling but not device performance.
Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel (TR) packaging supplies components on continuous tape suitable for automated pick-and-place assembly. Cut Tape (CT) provides individual tape segments. Digi-Reel® is a proprietary format combining benefits of both. All formats contain identical components; packaging choice depends on assembly equipment and volume requirements.
Q: Can I use S-8241ABKMC-GBKT2G as a direct replacement? A: The S-8241ABKMC-GBKT2G is a parametric equivalent with identical electrical and protection specifications. However, it uses SOT-23-5 packaging instead of SOT-25, requiring PCB footprint changes. Additionally, this part carries "Not For New Designs" status. Use only when AP9101 parts are unavailable and PCB redesign is feasible.
Q: Are all substitutes ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility for applications requiring these certifications.
Q: Why are some AP9101 variants marked as Obsolete? A: Obsolete status indicates that Diodes Incorporated has discontinued active production of those specific packaging variants. The AP9101CAK-AETRG1 (Active status) remains the current production part. Obsolete variants may still be available from inventory but should not be selected for new designs.
