Substitute Part Grouping Explanation

Substitute parts for the AP9214LA-AB-HSB-7 are qualified based on the following criteria:

Electrical Equivalence: All substitute parts maintain identical function (Battery Protection), battery chemistry (Lithium Ion/Polymer), single-cell configuration, and fault protection capabilities (Over Current, Over Voltage, Short Circuit).

Thermal Compatibility: All substitutes operate within the same temperature range (-40°C ~ 85°C TA).

Mechanical Compatibility: All substitutes use the identical 6-UDFN Exposed Pad package (U-DFN2535-6) with surface-mount configuration, ensuring PCB layout compatibility without redesign.

Regulatory Compliance: All substitutes maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating.

Product Status Distinction: The main part (AP9214LA-AB-HSB-7) is obsolete. All listed substitutes are active products, providing long-term availability for production and design continuity.

Packaging Format: The main part uses standard packaging; substitutes are available in Tape & Reel (TR) format, which is standard for production environments.

Engineering Selection Recommendations

All listed substitute parts are direct functional equivalents to the AP9214LA-AB-HSB-7. Selection should prioritize active product status and inventory availability:

AP9214L-AE-HSBR-7 offers the highest inventory level (9200 units), providing optimal supply chain security for production environments requiring single-cell lithium battery protection with identical electrical and mechanical specifications.

AP9214L-AG-HSBR-7 (3195 units) and AP9214L-AD-HSBR-7 (1103 units) provide secondary options with substantial inventory depth.

All substitutes maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the original part. The 6-UDFN Exposed Pad package ensures direct PCB compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can AP9214L series parts directly replace AP9214LA series parts?

A: Yes. Both series share identical electrical function (single-cell lithium battery protection with over-current, over-voltage, and short-circuit protection), thermal specifications (-40°C to 85°C), and mechanical packaging (6-UDFN Exposed Pad). The suffix variations indicate different internal protection thresholds or timing parameters, but all maintain the same package footprint and pin configuration.

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

A: HSB indicates standard packaging format; HSBR indicates Tape & Reel format. Both use the identical 6-UDFN Exposed Pad package (U-DFN2535-6). HSBR is standard for high-volume production. The physical component and PCB footprint are identical.

Q: Why is the original part (AP9214LA-AB-HSB-7) listed as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. Active equivalent parts from the same AP9214 family provide identical functionality and are recommended for new designs and production continuity.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitutes maintain ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original part.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes. All substitute parts use the identical 6-UDFN Exposed Pad package with the same pin configuration and footprint. No PCB redesign is required for substitution.
