AP9101CK6-BATRG1 Equivalent & Substitute Parts

Part Overview

The AP9101CK6-BATRG1 is a Battery Protection IC for single-cell Lithium Ion/Polymer applications, manufactured by Diodes Incorporated. This Surface Mount device in SOT-23-6 package provides Over Current and Over Voltage fault protection. The part is currently Active and suitable for new designs. Due to the Active status of the main part and the Obsolete or Not For New Designs status of many substitute variants, identifying compatible alternatives is essential for supply chain continuity and long-term production planning.

Substitute Part Grouping Explanation

Substitution eligibility for the AP9101CK6-BATRG1 is determined by the following parameters:

Base Product Number: AP9101
Battery Chemistry: Lithium Ion/Polymer
Number of Cells: 1
Fault Protection: Over Current, Over Voltage
Package / Case: SOT-23-6
Mounting Type: Surface Mount
Operating Temperature Range: -40°C ~ 85°C (TA)
RoHS Status: ROHS3 Compliant
REACH Status: REACH Unaffected

All identified substitute parts share these core electrical and mechanical parameters. Variations exist in packaging format (Tape & Reel vs. Cut Tape & Digi-Reel), Moisture Sensitivity Level (MSL 1 vs. MSL 3), and product lifecycle status. These variations do not affect functional equivalence but may impact procurement, storage, and design phase applicability.

Engineering Selection Recommendations

For new designs, AP9101CK6-BATRG1 is the recommended choice due to its Active product status and full compliance with ROHS3 and REACH requirements.

For existing designs or legacy applications requiring substitution:

AP9101CAK6-ATTRG1 is suitable for applications where new design qualification is not required, as it maintains Tape & Reel packaging and MSL 1 specifications identical to the main part, with the exception of its Not For New Designs status.

AP9101CK6-AXTRG1 and AP9101CK6-ANTRG1 offer the highest inventory availability among Tape & Reel variants with Obsolete status. Both maintain MSL 1 and full compliance certifications.

AP9101CK6-ADTRG1 is functionally equivalent but carries MSL 3 (168 Hours) instead of MSL 1 (Unlimited). This requires controlled storage and handling procedures and is suitable only for applications where moisture sensitivity management is feasible.

Cut Tape & Digi-Reel variants (AP9101CAK6-ABTRG1, AP9101CAK6-ANTRG1, AP9101CK6-AETRG1) are suitable for lower-volume or prototype applications where reel packaging is not required.

Frequently Asked Questions (FAQ)

Q: Can I use an Obsolete part as a substitute for the Active AP9101CK6-BATRG1?

A: Functionally, yes. All substitute parts share identical electrical specifications, battery chemistry support, fault protection features, and package dimensions. However, Obsolete parts are no longer manufactured and have limited supply. Use only when the Active part is unavailable and supply chain continuity is assured.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel (TR) packaging is supplied on continuous reels suitable for high-volume automated assembly. Cut Tape & Digi-Reel packaging provides smaller quantities on tape segments, suitable for lower-volume production or prototype builds. Both formats contain identical components.

Q: Does MSL 3 (168 Hours) affect my design?

A: MSL 3 requires that the component be used within 168 hours of package opening if stored above 30°C and 60% relative humidity. If your manufacturing environment maintains controlled temperature and humidity, or if you use the component within the specified timeframe, MSL 3 is compatible. MSL 1 (Unlimited) has no such storage restrictions.

Q: Are all substitute parts ROHS3 and REACH compliant?

A: Yes. All listed substitute parts maintain ROHS3 Compliant and REACH Unaffected status, ensuring regulatory compliance across all variants.

Q: Can I mix packaging formats in production?

A: Yes, provided your assembly equipment can handle both Tape & Reel and Cut Tape & Digi-Reel formats. Verify equipment compatibility before implementation.
