Substitute Part Grouping Explanation
All substitute parts listed are parametric equivalents manufactured by Diodes Incorporated under the AP9101 base product number. Substitution is determined by the following criteria:
- Identical battery chemistry (Lithium Ion/Polymer)
- Identical cell count (1 cell)
- 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 RoHS3 compliance and MSL rating
- Identical REACH status
Substitute parts differ only in packaging format (Tape & Reel vs. Cut Tape vs. Cut Tape & Digi-Reel) and product status. All parts maintain electrical and mechanical compatibility with the main part AP9101CAK-BETRG1.

Engineering Selection Recommendations
For direct pin-compatible substitution within the AP9101 family, all Diodes Incorporated variants maintain identical electrical and mechanical specifications. Selection among AP9101CAK-BETRG1 and its Diodes equivalents should be based on packaging format requirements:
- Tape & Reel (TR) format: AP9101CAK-BETRG1 (Active), AP9101CAK-BRTRG1 (Obsolete), AP9101CAK-CPTRG1 (Obsolete)
- Cut Tape (CT) & Digi-Reel format: AP9101CAK-ABTRG1 (Obsolete), AP9101CAK-AKTRG1 (Obsolete), AP9101CK-AHTRG1 (Obsolete)
- Cut Tape (CT) format: AP9101CAK-ANTRG1 (Obsolete), AP9101CK-AKTRG1 (Obsolete), AP9101CK-ASTRG1 (Obsolete), AP9101CK-AUTRG1 (Obsolete)
The BQ29733DSET from Texas Instruments is a manufacturer-recommended alternative with different packaging (6-WSON vs. SOT-25) and expanded fault protection (includes short circuit and under-voltage detection). This part requires PCB layout redesign and is not pin-compatible. Selection of BQ29733DSET is appropriate only when design specifications explicitly allow package and pinout changes and when the additional protection features are required.
Frequently Asked Questions (FAQ)
Q: Can AP9101CAK-BETRG1 be replaced with any of the listed AP9101 variants?
A: Yes. All AP9101 variants from Diodes Incorporated are parametric equivalents with identical electrical performance and SOT-25 packaging. Differences are limited to packaging format (Tape & Reel, Cut Tape, or Cut Tape & Digi-Reel) and product status. Selection depends on manufacturing process requirements and inventory availability.
Q: What is the difference between Tape & Reel and Cut Tape packaging?
A: Tape & Reel (TR) packaging supplies components on continuous carrier tape in reel format, suitable for high-volume automated assembly. Cut Tape (CT) provides components on cut segments of carrier tape. Cut Tape & Digi-Reel combines cut tape with a reel for intermediate volumes. All formats contain identical components; packaging format affects handling and assembly equipment compatibility only.
Q: Is BQ29733DSET a direct replacement for AP9101CAK-BETRG1?
A: No. BQ29733DSET uses 6-WSON packaging instead of SOT-25 and has different pinout. It is not pin-compatible and requires PCB redesign. BQ29733DSET is a manufacturer-recommended alternative only when design changes are acceptable and when the additional fault protection features (short circuit and under-voltage detection) are required.
Q: Why are some AP9101 variants marked as Obsolete?
A: Obsolete status indicates the manufacturer has discontinued production. These parts may still be available from inventory but are not recommended for new designs. AP9101CAK-BETRG1 (Active status) is the current production part and is recommended for new applications.
Q: Are all listed parts RoHS3 compliant?
A: Yes. All AP9101 variants and BQ29733DSET are ROHS3 Compliant with MSL rating of 1 (Unlimited moisture sensitivity level). All parts are REACH Unaffected.
Q: Can packaging format be changed during production?
A: Packaging format changes are possible if manufacturing equipment supports multiple tape formats. However, this requires process validation and may affect supply chain logistics. Consult with your manufacturing partner regarding format compatibility with existing assembly equipment.
