Substitute Part Grouping Explanation
Substitution of AP9101CK6-CITRG1 is determined by the following criteria:
All substitute parts share identical electrical and functional specifications: single-cell lithium ion/polymer battery protection with over-current and over-voltage fault protection, operating temperature range of -40°C to 85°C, SOT-23-6 package configuration, and SOT-26 supplier device package designation.
Substitutes are differentiated by two primary parameters:
-
Product Status: The main part (AP9101CK6-CITRG1) is Active. Substitute parts carry status designations of Obsolete or Not For New Designs, indicating they are available for replacement purposes but not recommended for new product designs.
-
Packaging Format: Substitutes are available in two packaging configurations: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel®. The main part uses Tape & Reel packaging.
All parts maintain ROHS3 compliance, REACH Unaffected status, and identical electrical protection characteristics. Moisture Sensitivity Level varies between MSL 1 (Unlimited) and MSL 3 (168 Hours), which affects storage and handling requirements but does not impact electrical functionality.

Engineering Selection Recommendations
For applications requiring an Active product status part, AP9101CK6-CITRG1 remains the primary selection. This part maintains full manufacturing support and is recommended for new designs.
For replacement or alternative sourcing of existing designs, AP9101CAK6-ATTRG1 carries Not For New Designs status and is suitable for legacy product support or inventory supplementation. This part is available in Tape & Reel packaging with MSL 1 rating and maintains full ROHS3 and REACH compliance.
Parts designated as Obsolete (AP9101CAK6-ABTRG1, AP9101CAK6-ANTRG1, AP9101CAK6-BVTRG1, AP9101CK6-ADTRG1, AP9101CK6-AETRG1, AP9101CK6-ANTRG1, AP9101CK6-AXTRG1, AP9101CK6-AYTRG1, AP9101CK6-BJTRG1) are available for existing product support but should not be selected for new designs. These parts are electrically equivalent and maintain identical compliance certifications.
Packaging format selection depends on manufacturing process requirements. Tape & Reel packaging is suitable for automated pick-and-place assembly. Cut Tape & Digi-Reel® packaging accommodates lower-volume or manual assembly processes.
MSL 3 (168 Hours) rating on AP9101CK6-ADTRG1 requires stricter moisture control during storage and handling compared to MSL 1 parts. This consideration applies only to supply chain and storage protocols and does not affect electrical performance.
Frequently Asked Questions (FAQ)
Q: Can AP9101CK6-CITRG1 be directly replaced with an Obsolete-status part?
A: Yes. All substitute parts listed share identical electrical specifications, fault protection characteristics, operating temperature range, and package configuration. Obsolete status indicates end-of-life manufacturing but does not affect functional compatibility. Electrical performance and protection thresholds remain unchanged.
Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?
A: Tape & Reel packaging is continuous and optimized for high-volume automated assembly. Cut Tape & Digi-Reel® packaging provides pre-cut segments suitable for lower-volume production or manual assembly processes. Both formats contain identical components in SOT-23-6 package configuration.
Q: Does MSL rating affect electrical performance?
A: No. Moisture Sensitivity Level (MSL) affects storage and handling requirements only. MSL 1 (Unlimited) allows indefinite storage under standard conditions. MSL 3 (168 Hours) requires controlled humidity storage and baking procedures before reflow soldering. Electrical functionality and protection characteristics are identical regardless of MSL rating.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All parts listed, including the main part AP9101CK6-CITRG1 and all substitutes, carry ROHS3 Compliant certification and REACH Unaffected status. Regulatory compliance is maintained across all equivalent parts.
Q: Which substitute part should be selected for new product designs?
A: AP9101CK6-CITRG1 is the only part with Active product status and is the recommended selection for new designs. Parts with Obsolete or Not For New Designs status should be reserved for legacy product support or replacement applications only.
Q: Can packaging format be changed during production?
A: Yes. Tape & Reel and Cut Tape & Digi-Reel® formats are interchangeable from an electrical and functional standpoint. Selection depends on manufacturing equipment capability and production volume requirements. Consult manufacturing process specifications to confirm compatibility with your assembly equipment.
