AP9101CAK-AITRG1 Equivalent & Substitute Parts

Part Overview

The AP9101CAK-AITRG1 is a battery protection IC for single-cell lithium ion/polymer applications, manufactured by Diodes Incorporated. This Surface Mount device in SOT-25 packaging provides over-current and over-voltage fault protection. The part is currently Active in product status. Substitute parts are necessary when the primary part becomes unavailable due to inventory constraints, supply chain disruptions, or when alternative packaging formats are required for manufacturing flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AP9101CAK-AITRG1 is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Battery Chemistry: Lithium Ion/Polymer
• Number of Cells: 1
• Fault Protection: Over Current, Over Voltage
• Operating Temperature Range: -40°C ~ 85°C (TA)

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: SC-74A, SOT-753
• Supplier Device Package: SOT-25

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed maintain identical electrical function and mechanical compatibility. Differences exist only in packaging format (Tape & Reel vs. Cut Tape) and product status. The primary part (AP9101CAK-AITRG1) is Active status; substitute parts from Diodes Incorporated are Obsolete status but remain electrically and mechanically equivalent.

Parameter Comparison

Engineering Selection Recommendations

Diodes Incorporated AP9101 Series (Recommended for Active Designs): The AP9101CAK-AITRG1 is the primary selection for new designs due to Active product status. All Diodes Incorporated AP9101 variants maintain identical electrical and mechanical specifications, differing only in packaging format. Selection among Diodes variants should be based on manufacturing assembly requirements: Tape & Reel (TR) packaging for automated pick-and-place equipment, or Cut Tape (CT) for manual assembly or lower-volume production.

Obsolete Diodes Incorporated Variants: AP9101CAK-ABTRG1, AP9101CAK-AKTRG1, AP9101CAK-ANTRG1, AP9101CAK-BRTRG1, AP9101CAK-CPTRG1, AP9101CK-AHTRG1, AP9101CK-AKTRG1, AP9101CK-ASTRG1, and AP9101CK-AUTRG1 are electrically and mechanically equivalent but carry Obsolete product status. These parts are suitable only for legacy system maintenance or repair applications where the original part number must be maintained.

Cross-Manufacturer Alternative: The S-8241ABKMC-GBKT2G from ABLIC Inc. meets all electrical and mechanical parameters but carries Not For New Designs status. This part is not recommended for new product development.

Frequently Asked Questions (FAQ)

Q: Can I substitute AP9101CAK-AITRG1 with any of the listed Diodes Incorporated variants? A: Yes. All Diodes Incorporated AP9101 variants are electrically and mechanically equivalent. Substitution is valid based on identical battery chemistry (Lithium Ion/Polymer), single-cell configuration, fault protection (Over Current, Over Voltage), operating temperature range (-40°C ~ 85°C), and package specifications (SOT-25, SC-74A, SOT-753). Differences exist only in packaging format and product status.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging? A: Tape & Reel packaging is supplied on continuous tape wound on reels, suitable for high-speed automated assembly equipment. Cut Tape packaging is supplied in individual tape segments, typically used for manual assembly, lower-volume production, or when specific quantities are required. Both formats contain identical components.

Q: Why are most substitute parts marked as Obsolete? A: Obsolete status indicates the manufacturer has discontinued active production and support for these part numbers. However, they remain electrically and mechanically equivalent to the Active part. Obsolete variants are available from existing inventory but are not recommended for new product designs.

Q: Is the ABLIC S-8241ABKMC-GBKT2G a suitable substitute? A: The S-8241ABKMC-GBKT2G meets all electrical and mechanical parameters but carries Not For New Designs status. It is not recommended for new product development. Use only for legacy system maintenance where cross-manufacturer substitution is unavoidable.

Q: Are all listed parts ROHS3 compliant? A: Yes. All parts listed, including the primary AP9101CAK-AITRG1 and all substitutes, are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can I mix packaging formats in the same production run? A: Mixing packaging formats (Tape & Reel vs. Cut Tape) is not recommended within a single production run due to different handling and assembly requirements. Select one packaging format per manufacturing batch to maintain process consistency and traceability.
