Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP9214L-AI-HSB-7 is determined by the following critical parameters:

Functional Equivalence: Battery Protection function for single-cell Lithium Ion/Polymer chemistry with over-current, over-voltage, and short-circuit fault protection.

Electrical Compatibility: Operating temperature range of -40°C ~ 85°C (TA).

Mechanical Compatibility: Surface Mount mounting type with compatible package footprints (6-UDFN Exposed Pad or equivalent 6-pin packages).

Regulatory Compliance: ROHS3 Compliant, REACH Unaffected, MSL 1 (Unlimited).

Substitute parts are grouped into two categories:

Diodes Incorporated AP9214 Series (Parametric Equivalents): Parts AP9214L-AK-HSBR-7, AP9214L-AN-HSB-7, and AP9214LA-AH-HSB-7, AP9214LA-AM-HSBR-7 share identical functional specifications, electrical parameters, and regulatory compliance. Differences exist only in packaging format (Tape & Reel vs. Cut Tape) and product status (Obsolete vs. Active).

Texas Instruments BQ29706DSER (MFR Recommended Alternative): This part provides equivalent battery protection functionality for single-cell Lithium Ion/Polymer applications with identical operating temperature range and regulatory compliance. Package format differs (6-WSON vs. 6-UDFN), requiring PCB layout verification. Product status is Active with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Package): Select AP9214L-AK-HSBR-7, AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, or AP9214LA-AM-HSBR-7. All maintain identical 6-UDFN Exposed Pad footprints and electrical specifications. These parts are suitable for designs where PCB layout cannot be modified. Note that AP9214L-AK-HSBR-7, AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, and AP9214LA-AM-HSBR-7 are marked Obsolete; verify long-term availability before design commitment.

For Active Product Status with Higher Inventory: Select BQ29706DSER from Texas Instruments. This part is Active in product status with 61,600 units in stock, providing superior supply chain security. The 6-WSON package requires PCB layout verification to confirm footprint compatibility. All regulatory compliance requirements (ROHS3, REACH Unaffected, MSL 1) are met. The BQ29706DSER adds under-voltage protection in addition to over-voltage protection.

For Packaging Format Flexibility: AP9214L-AK-HSBR-7 is available in Cut Tape format if reel packaging is not required. All other Diodes Incorporated variants are available in Tape & Reel format.

Frequently Asked Questions (FAQ)

Q: Can AP9214L-AK-HSBR-7 be used as a direct replacement for AP9214L-AI-HSB-7?

A: Yes. Both parts share identical functional specifications, electrical parameters, operating temperature range, and regulatory compliance. The only differences are packaging format (Cut Tape vs. Tape & Reel) and product status (Obsolete vs. Active). PCB footprint compatibility is identical (6-UDFN Exposed Pad).

Q: What is the difference between AP9214L-AN-HSB-7 and AP9214LA-AH-HSB-7?

A: Both parts are functionally equivalent with identical electrical specifications, operating temperature range, and package footprint. The difference is in the part number designation (L vs. LA variant). Both are marked Obsolete. Verify with the manufacturer regarding any internal design differences.

Q: Can BQ29706DSER replace AP9214L-AI-HSB-7 without PCB redesign?

A: BQ29706DSER provides equivalent battery protection functionality for single-cell Lithium Ion/Polymer applications. However, the package differs (6-WSON vs. 6-UDFN Exposed Pad). PCB layout verification is required to confirm footprint compatibility. If the PCB layout cannot accommodate the 6-WSON package, use one of the Diodes Incorporated AP9214 variants instead.

Q: Why is BQ29706DSER recommended as an alternative despite the package difference?

A: BQ29706DSER is Active in product status with 61,600 units in inventory, compared to Obsolete status for most AP9214 variants. This provides superior long-term supply chain availability. The part meets all regulatory requirements (ROHS3 Compliant, REACH Unaffected, MSL 1). The additional under-voltage protection feature may provide enhanced functionality for certain applications.

Q: Are all substitute parts ROHS3 Compliant and REACH Unaffected?

A: Yes. All parts listed—AP9214L-AK-HSBR-7, AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, AP9214LA-AM-HSBR-7, and BQ29706DSER—are ROHS3 Compliant with REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts operate within -40°C ~ 85°C (TA), identical to the AP9214L-AI-HSB-7.

Q: Which substitute part has the highest inventory availability?

A: BQ29706DSER has the highest inventory with 61,600 units in stock. Among Diodes Incorporated variants, AP9214L-AK-HSBR-7 has the highest inventory at 9,600 units.
