AP9214L-AF-HSB-7 Equivalent & Substitute Parts

Part Overview

The AP9214L-AF-HSB-7 is a battery protection IC for single-cell lithium ion/polymer applications manufactured by Diodes Incorporated. This Surface Mount Device (SMD) in 6-UDFN packaging provides over-current, over-voltage, and short-circuit protection. The part is currently in Active product status with 780 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life, inventory constraints occur, or alternative packaging formats are required for manufacturing flexibility. The AP9214L-AF-HSB-7 has documented parametric equivalents within the Diodes Incorporated AP9214 series, as well as a manufacturer-recommended alternative from Texas Instruments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP9214L-AF-HSB-7 is determined by the following criteria:

Primary Substitution Criteria:

• 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)

Secondary Considerations:

• Packaging format (Tape & Reel vs. Cut Tape)
• Product status (Active vs. Obsolete)
• Package case type (6-UDFN vs. 6-WFDFN)

The AP9214 series variants (AP9214L-AK-HSBR-7, AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, AP9214LA-AM-HSBR-7) maintain identical electrical specifications and thermal performance. The BQ29729DSER from Texas Instruments is a manufacturer-recommended alternative that meets all functional and environmental requirements while offering Active product status.

Parameter Comparison

Engineering Selection Recommendations

For Diodes Incorporated AP9214 Series Substitution:

The AP9214L-AK-HSBR-7, AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, and AP9214LA-AM-HSBR-7 are parametric equivalents with identical electrical and thermal specifications. Selection among these variants depends on packaging requirements and product lifecycle status. While these parts are marked Obsolete, they remain functionally equivalent for applications requiring the 6-UDFN package format. Tape & Reel (TR) packaging variants (AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, AP9214LA-AM-HSBR-7) maintain the same format as the primary part.

For Texas Instruments BQ29729DSER Substitution:

The BQ29729DSER is the manufacturer-recommended alternative and maintains Active product status. This part provides identical single-cell lithium ion/polymer protection with the same operating temperature range and RoHS3 compliance. The BQ29729DSER uses a 6-WFDFN package instead of 6-UDFN, requiring PCB layout verification for pin compatibility and thermal performance. The BQ29729DSER includes under-voltage protection in addition to the standard over-current, over-voltage, and short-circuit protection.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), REACH Unaffected status, and identical ECCN and HTSUS classifications, ensuring regulatory equivalence for procurement and supply chain purposes.

Frequently Asked Questions (FAQ)

Q: Can AP9214L-AK-HSBR-7 replace AP9214L-AF-HSB-7 directly?

A: Yes, electrically and thermally. The primary difference is packaging format: AP9214L-AK-HSBR-7 uses Cut Tape (CT) while AP9214L-AF-HSB-7 uses Tape & Reel (TR). Both use identical 6-UDFN packages. Verify your assembly equipment compatibility with the packaging format before substitution.

Q: What is the difference between AP9214L and AP9214LA variants?

A: Both variants provide identical battery protection functionality and specifications. The designation difference reflects internal Diodes Incorporated product line management. Electrical performance, thermal characteristics, and package dimensions are equivalent.

Q: Can BQ29729DSER be used as a drop-in replacement?

A: BQ29729DSER is functionally equivalent but uses a different package (6-WFDFN vs. 6-UDFN). PCB layout and footprint verification is required. The BQ29729DSER includes under-voltage protection, providing enhanced functionality. Pin-to-pin compatibility must be confirmed with device datasheets before PCB redesign.

Q: Why are some AP9214 variants marked Obsolete?

A: Obsolete status indicates these parts are no longer in active production. However, existing inventory remains available. For new designs or long-term supply assurance, the Active status AP9214L-AF-HSB-7 or BQ29729DSER are preferred.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, MSL Level 1, and REACH Unaffected status, ensuring regulatory equivalence for procurement across all regions.

Q: What is the impact of packaging format on assembly?

A: Tape & Reel (TR) and Cut Tape (CT) formats affect only the supply and handling method, not the component itself. Verify your pick-and-place equipment supports the packaging format. Both formats contain identical components in identical packages.
