AP9214L-AL-HSBR-7 Equivalent & Substitute Parts

Part Overview

The AP9214L-AL-HSBR-7 is a battery protection IC for single-cell lithium ion/polymer applications manufactured by Diodes Incorporated. This active product provides over-current, over-voltage, and short-circuit protection in a 6-UDFN exposed pad surface mount package. The part is currently in active production status with 1147 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for supply chain optimization, or when design flexibility demands selection from multiple qualified sources within the same functional category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following 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)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parts are grouped into two categories:

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

Texas Instruments BQ29729DSER (Manufacturer-Recommended Alternative): This part meets all core electrical and functional requirements but uses a different package type (6-WSON versus 6-UDFN) and includes under-voltage protection in addition to the specified fault protections. This represents a cross-manufacturer substitute with enhanced protection capabilities.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Status Requirement: Select AP9214L-AL-HSBR-7 (primary) or BQ29729DSER (alternative). Both parts maintain active production status and full manufacturer support.

For Diodes Incorporated Ecosystem: AP9214L-AL-HSBR-7 is the preferred choice. All AP9214 series variants are functionally equivalent and share identical electrical specifications. Selection among AP9214L-AK-HSBR-7, AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, and AP9214LA-AM-HSBR-7 depends on packaging format availability and acceptance of obsolete product status.

For Cross-Manufacturer Substitution: BQ29729DSER from Texas Instruments meets all core functional requirements with active product status. This part includes under-voltage protection as an additional feature. Package geometry differs (6-WSON versus 6-UDFN), requiring PCB layout verification for pin-to-pin compatibility.

For Compliance and Certifications: All listed parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings. No compliance restrictions apply to any substitute selection.

Frequently Asked Questions (FAQ)

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

A: Yes, from an electrical and functional standpoint. Both parts share identical specifications for battery chemistry, cell count, fault protection, operating temperature, and package type (6-UDFN). The difference is packaging format (Cut Tape versus Tape & Reel) and product status (Obsolete versus Active). Verify that your assembly process accepts Cut Tape format and that obsolete product status aligns with your supply chain requirements.

Q: What is the difference between the AP9214 variants (AL, AK, AN, LA-AH, LA-AM)?

A: All variants are functionally identical single-cell lithium ion/polymer battery protection ICs with the same electrical specifications. Differences are limited to packaging format (Tape & Reel or Cut Tape) and product lifecycle status (Active or Obsolete). The suffix designations reflect internal Diodes Incorporated product line management and do not indicate functional differences.

Q: Can BQ29729DSER replace AP9214L-AL-HSBR-7 in my design?

A: Electrical and functional compatibility exists. Both parts protect single-cell lithium ion/polymer batteries with over-current, over-voltage, and short-circuit protection across the same operating temperature range. BQ29729DSER adds under-voltage protection. The critical difference is package type: BQ29729DSER uses 6-WSON (1.5x1.5mm) while AP9214L-AL-HSBR-7 uses 6-UDFN. PCB layout and pin assignment must be verified for mechanical and electrical compatibility before design substitution.

Q: Are all these parts RoHS compliant?

A: Yes. All listed parts carry ROHS3 compliance certification and are REACH unaffected. No environmental or regulatory restrictions apply to any substitute selection.

Q: What does MSL 1 (Unlimited) mean for these parts?

A: MSL 1 indicates the lowest moisture sensitivity level. These parts have unlimited shelf life and do not require special moisture control during storage or handling. Standard ESD precautions apply, but no baking or desiccant storage is required.

Q: Which part should I select for a new design?

A: AP9214L-AL-HSBR-7 is the recommended choice for new designs. It maintains active product status with full manufacturer support and adequate inventory. If cross-manufacturer flexibility is required, BQ29729DSER from Texas Instruments is an active alternative with equivalent functional capability.
