Substitute Part Grouping Explanation

Substitution of the AP9214LA-AD-HSB-7 is determined by the following critical parameters:

Battery Chemistry: Lithium Ion/Polymer
Number of Cells: 1
Fault Protection: Over Current, Over Voltage, Short Circuit
Operating Temperature Range: -40°C ~ 85°C (TA)
Package / Case: 6-UDFN Exposed Pad
Supplier Device Package: U-DFN2535-6
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed maintain identical electrical specifications and mechanical compatibility. Variations in part numbering (suffix designations such as -AA, -AD, -AE, -AF, -AG, -AH, -AI, -AJ) represent internal configuration differences that do not affect functional equivalence for single-cell lithium battery protection applications. Packaging format differences (Tape & Reel vs. standard packaging) do not impact electrical or mechanical compatibility.

Engineering Selection Recommendations

All listed substitute parts are manufactured by Diodes Incorporated and maintain ROHS3 compliance and REACH unaffected status identical to the main part. The primary distinction is product status: the AP9214LA-AD-HSB-7 is obsolete, while all substitute variants are active products with current manufacturing support.

For new designs or production requiring long-term component availability, selection from active product variants is appropriate. AP9214L-AE-HSBR-7 offers the highest current inventory (9200 units), followed by AP9214L-AG-HSBR-7 (3195 units), providing supply continuity for volume applications. All variants are electrically and mechanically interchangeable for single-cell lithium battery protection circuits operating within the -40°C to 85°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can AP9214L-AE-HSBR-7 directly replace AP9214LA-AD-HSB-7 in existing designs?

A: Yes. Both parts share identical electrical specifications for battery protection (over-current, over-voltage, short-circuit), operate across the same temperature range (-40°C ~ 85°C), and use the same 6-UDFN Exposed Pad package. No circuit modifications are required.

Q: What is the difference between HSB and HSBR packaging designations?

A: HSB and HSBR designations indicate different packaging formats (standard vs. Tape & Reel). Both formats contain identical die and electrical performance. Selection depends on procurement and assembly requirements, not electrical compatibility.

Q: Why are there multiple part number variants with different suffix letters?

A: Suffix variations (AA, AD, AE, AF, AG, AH, AI, AJ) represent internal configuration options within the AP9214 family. All variants maintain the same core battery protection functionality and are electrically equivalent for single-cell lithium applications.

Q: Is MSL (Moisture Sensitivity Level) 1 suitable for standard PCB assembly processes?

A: Yes. MSL 1 indicates unlimited shelf life and no special moisture handling requirements, making these components suitable for standard surface-mount assembly without baking or desiccant storage.

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.
