Substitute Part Grouping Explanation
Substitution of AP9101CAK-BATRG1 is determined by strict equivalence across the following parameters:
- Manufacturer: Diodes Incorporated (primary equivalents) or ABLIC Inc. (cross-manufacturer alternative)
- Base Product Number: AP9101 or S-8241
- Function: Battery Protection for single-cell lithium ion/polymer
- Fault Protection: Over Current and Over Voltage
- Operating Temperature: -40°C ~ 85°C (TA)
- Mounting Type: Surface Mount

Engineering Selection Recommendations
For Active Production Designs: AP9101CAK-BATRG1 remains the primary selection as the only Active status part in this equivalence group. It is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.
For Obsolete Part Replacement: All Diodes Incorporated AP9101 variants (AP9101CAK-ABTRG1, AP9101CAK-AKTRG1, AP9101CAK-ANTRG1, AP9101CAK-BRTRG1, AP9101CAK-CPTRG1, AP9101CK-AHTRG1, AP9101CK-AKTRG1, AP9101CK-ASTRG1, AP9101CK-AUTRG1) are direct electrical and functional equivalents. Selection among these variants depends on packaging requirements: Tape & Reel (TR) for automated assembly, or Cut Tape (CT) for manual or lower-volume applications.
For Cross-Manufacturer Substitution: The ABLIC Inc. S-8241ABKMC-GBKT2G provides equivalent battery protection functionality with identical electrical specifications and compliance certifications. However, this part carries "Not For New Designs" status and uses SOT-23-5 packaging instead of SOT-25, requiring PCB layout modification.
Frequently Asked Questions (FAQ)
Q: Can AP9101CAK-BATRG1 be replaced with any of the obsolete AP9101 variants?
A: Yes. All Diodes Incorporated AP9101 variants listed are parametric equivalents with identical electrical function, battery chemistry support, fault protection, operating temperature range, and compliance status. Selection is based on packaging format availability and assembly process requirements.
Q: What is the difference between Tape & Reel and Cut Tape packaging?
A: Tape & Reel (TR) packaging is used for high-speed automated pick-and-place assembly. Cut Tape (CT) is supplied in individual tape segments and is suitable for manual assembly or lower-volume production. Both formats contain the same component in the same SOT-25 package.
Q: Can the ABLIC S-8241ABKMC-GBKT2G replace AP9101CAK-BATRG1?
A: The S-8241ABKMC-GBKT2G provides equivalent battery protection functionality and meets the same compliance requirements. However, it uses SOT-23-5 packaging instead of SOT-25, which requires PCB layout changes. Additionally, this part is marked "Not For New Designs," limiting its suitability for new product development.
Q: Are all listed parts ROHS3 compliant?
A: Yes. All parts in this equivalence group are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
Q: Which variant has the highest inventory availability?
A: AP9101CK-AHTRG1 has the highest inventory at 14,500 pieces, followed by AP9101CK-ASTRG1 at 9,400 pieces and AP9101CAK-ANTRG1 at 9,300 pieces.
