Substitute Part Grouping Explanation
Substitution of the AP9101CK-AATRG1 is determined by the following critical parameters:
Function, Battery Chemistry, Number of Cells, Fault Protection, Operating Temperature Range, Mounting Type, Package/Case, and Supplier Device Package must remain identical across all substitute parts. These parameters define the electrical and mechanical compatibility required for direct substitution in single-cell lithium battery protection applications.
Packaging format (Tape & Reel, Cut Tape, or Cut Tape & Digi-Reel) may vary based on manufacturing and procurement requirements, as these represent different distribution methods for the same component. Product Status may differ between Active and Obsolete designations; however, Obsolete parts remain functionally equivalent and electrically identical.
The AP9101 base product number identifies the core device family. All substitute parts listed share this base designation with varying suffix codes that indicate packaging and distribution channel differences only.

Engineering Selection Recommendations
For new designs and active production, AP9101CK-AATRG1 is the recommended primary selection due to its Active product status. This part maintains full ROHS3 compliance, REACH Unaffected status, and unlimited moisture sensitivity rating (MSL 1).
When AP9101CK-AATRG1 becomes unavailable, direct substitutes from the Diodes Incorporated AP9101 family are electrically and mechanically equivalent. Selection among AP9101CAK-ABTRG1, AP9101CAK-AKTRG1, AP9101CAK-ANTRG1, AP9101CAK-BRTRG1, AP9101CAK-CPTRG1, AP9101CK-AHTRG1, AP9101CK-AKTRG1, AP9101CK-ASTRG1, and AP9101CK-AUTRG1 should be based on packaging format requirements and inventory availability. All maintain identical electrical specifications, operating temperature range, and compliance certifications.
The S-8241ABKMC-GBKT2G from ABLIC Inc. is functionally equivalent but uses SOT-23-5 package format instead of SOT-25. This part carries "Not For New Designs" status and should be used only when SOT-23-5 package compatibility is confirmed and AP9101 family parts are unavailable.
Frequently Asked Questions (FAQ)
Q: Can AP9101CAK-ABTRG1 replace AP9101CK-AATRG1 directly?
A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: AP9101CK-AATRG1 is supplied in Tape & Reel format, while AP9101CAK-ABTRG1 is supplied in Cut Tape & Digi-Reel format. Verify your assembly equipment can process the alternative packaging format.
Q: What is the difference between Cut Tape (CT), Cut Tape & Digi-Reel, and Tape & Reel (TR)?
A: These are distribution and packaging methods only. Cut Tape provides individual component strips for manual or semi-automated placement. Digi-Reel is a reusable reel format. Tape & Reel is the standard continuous reel format for automated pick-and-place equipment. All three formats contain identical components with identical electrical performance.
Q: Why is AP9101CAK-ABTRG1 marked Obsolete if it is equivalent?
A: Product Status reflects manufacturing and distribution status, not functional capability. Obsolete parts remain electrically and mechanically identical to Active parts. Obsolete designation indicates the manufacturer is not producing new stock, though existing inventory may be available. For long-term production, prioritize Active status parts.
Q: Can S-8241ABKMC-GBKT2G be used as a substitute?
A: S-8241ABKMC-GBKT2G is functionally equivalent but uses SOT-23-5 package instead of SOT-25. Direct PCB substitution is not possible without layout modification. This part is marked "Not For New Designs" and should be considered only when SOT-23-5 compatibility is confirmed and all AP9101 variants are unavailable.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the primary part's regulatory certifications.
Q: What is the operating temperature range for all these parts?
A: All substitute parts operate across -40°C to 85°C (TA), identical to the AP9101CK-AATRG1 primary part.
