Substitute Part Grouping Explanation
Substitution eligibility for the AP9101CK-AUTRG1 is determined by strict equivalence across the following critical parameters:
- Battery Chemistry: Lithium Ion/Polymer
- Number of Cells: Single cell (1)
- Fault Protection: Over Current and Over Voltage
- Operating Temperature Range: -40°C ~ 85°C
- Package / Case: SC-74A, SOT-753 (SOT-25)

Engineering Selection Recommendations
For applications currently using AP9101CK-AUTRG1, direct substitution is supported by all listed equivalent parts. Selection between active alternatives should prioritize product status and availability:
Active status parts (AP9101CAK-AATRG1, AP9101CAK-ACTRG1, AP9101CAK-ADTRG1, AP9101CAK-AETRG1, AP9101CAK-AFTRG1, AP9101CAK-AGTRG1, AP9101CAK-AHTRG1, AP9101CAK-AITRG1, AP9101CAK-AJTRG1) are recommended for new designs and ongoing production. These parts maintain full ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.
Packaging format selection depends on procurement workflow: Tape & Reel (TR) packaging suits high-volume automated assembly, while Cut Tape (CT) variants accommodate lower-volume or manual placement scenarios. Electrical and mechanical performance remains identical across packaging formats.
Frequently Asked Questions (FAQ)
Q: Can AP9101CAK-AATRG1 replace AP9101CK-AUTRG1 in existing designs?
A: Yes. Both parts are electrically and mechanically equivalent. They share identical battery chemistry (Lithium Ion/Polymer), single-cell configuration, fault protection (over-current and over-voltage), operating temperature range (-40°C ~ 85°C), and SOT-25 package specifications. The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. Cut Tape).
Q: What is the difference between Cut Tape and Tape & Reel packaging?
A: Cut Tape (CT) and Tape & Reel (TR) represent different delivery formats for the same component. Cut Tape is supplied in individual strips, suitable for lower-volume applications or manual assembly. Tape & Reel provides continuous reel format optimized for automated pick-and-place assembly in high-volume production. Electrical specifications and physical package dimensions (SOT-25) are identical.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
Q: Why is the main part AP9101CK-AUTRG1 marked as Obsolete?
A: Obsolete status indicates the part has reached end-of-life in the manufacturer's product lifecycle. Active equivalent alternatives are available to support continued design and production requirements without functional compromise.
Q: Can I mix packaging formats in the same production run?
A: Packaging format does not affect electrical or mechanical compatibility. However, procurement and assembly workflow considerations may influence practical implementation. Standardizing on a single packaging format within a production run simplifies logistics and assembly processes.
