Substitute Part Grouping Explanation

Substitution of the AP9214LA-AJ-HSBR-7 is determined by strict equivalence across the following parameters:

Manufacturer: Diodes Incorporated (all substitutes from same manufacturer)
Base Product Number: AP9214 (all substitutes share this base designation)
Function: Battery Protection for single-cell Lithium Ion/Polymer
Fault Protection: Over Current, Over Voltage, Short Circuit
Package / Case: 6-UDFN Exposed Pad (U-DFN2535-6)
Operating Temperature Range: -40°C ~ 85°C (TA)
Compliance: ROHS3 Compliant, REACH Unaffected
Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts maintain identical electrical functionality and mechanical compatibility. Variations in part number suffixes (such as -AA, -AD, -AE, -AF, -AG, -AH, -AI, -AJ) represent internal design variants within the AP9214 family that do not affect interchangeability for the specified application parameters.

Engineering Selection Recommendations

The AP9214LA-AJ-HSBR-7 is classified as obsolete. Direct replacement with active equivalents from the AP9214L series is required for new production and ongoing system support. All listed substitute parts maintain identical electrical specifications, thermal operating range, and mechanical package compatibility.

Selection among active alternatives should prioritize parts with highest inventory availability and confirmed active product status. AP9214L-AE-HSBR-7 offers the highest inventory level (9200 units) while maintaining full parametric equivalence. All substitutes carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Packaging designation differences (HSB versus HSBR suffix) indicate tape and reel configuration variants. Both configurations are mechanically and electrically equivalent for PCB assembly operations.

Frequently Asked Questions (FAQ)

Q: Can AP9214L series parts directly replace the AP9214LA-AJ-HSBR-7?

A: Yes. All AP9214L variants listed maintain identical electrical function, thermal specifications, and 6-UDFN package compatibility. The suffix variations in part numbers do not affect interchangeability for single-cell Lithium Ion/Polymer battery protection applications.

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

A: Both HSB and HSBR designations refer to tape and reel packaging configurations suitable for automated PCB assembly. They are mechanically and electrically equivalent. Selection between them depends on procurement and assembly process requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory standards.

Q: Which substitute part offers the best availability?

A: AP9214L-AE-HSBR-7 maintains the highest inventory level at 9200 units while meeting all parametric equivalence requirements.

Q: Do the internal design variants (indicated by suffix letters) affect circuit performance?

A: No. All AP9214L variants provide identical over-current, over-voltage, and short-circuit protection functionality across the specified -40°C to 85°C operating temperature range. Suffix variations represent internal design iterations that do not impact system-level performance or compatibility.
