AP9214L-AD-HSBR-7 Equivalent & Substitute Parts

Part Overview

The AP9214L-AD-HSBR-7 is a single-cell lithium ion/polymer battery protection IC manufactured by Diodes Incorporated in the 6-UDFN package with exposed pad. This active product provides over-current, over-voltage, and short-circuit protection for single-cell battery applications. Substitute parts are necessary when the primary part reaches end-of-life status, inventory constraints occur, or alternative packaging formats are required for manufacturing flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the AP9214L-AD-HSBR-7 is determined by the following critical parameters:

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)
• Package / Case: 6-UDFN Exposed Pad or equivalent footprint
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Substitute Categories:

Category 1: Diodes Incorporated AP9214 Series (Same Manufacturer, Same Base Product) Parts AP9214L-AK-HSBR-7, AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, and AP9214LA-AM-HSBR-7 share identical electrical specifications and package footprint. Differences exist only in packaging format (Tape & Reel vs. Cut Tape) and product status. These parts are direct parametric equivalents.

Category 2: Texas Instruments BQ297xx Series (Cross-Manufacturer Alternatives) Parts BQ29703DSER and BQ29717DSET are manufacturer-recommended alternatives from Texas Instruments. While maintaining identical functional specifications (single-cell lithium ion/polymer protection with over-current, over-voltage, and short-circuit protection), these parts use the 6-WSON package instead of 6-UDFN. Both maintain the same operating temperature range and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Footprint Compatibility (6-UDFN Package): Select from the Diodes Incorporated AP9214 series substitutes (AP9214L-AK-HSBR-7, AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, AP9214LA-AM-HSBR-7). These parts maintain identical package geometry and electrical specifications. All are ROHS3 compliant with MSL rating of 1. Note that these alternatives carry obsolete product status; verify long-term availability with suppliers before design commitment.

For Cross-Manufacturer Alternatives (6-WSON Package): The Texas Instruments BQ29703DSER and BQ29717DSET are active products with higher inventory availability. Both maintain identical functional specifications and operating temperature range. PCB layout modification is required due to package footprint change from 6-UDFN to 6-WSON (1.5x1.5). Both parts include under-voltage detection in addition to the over-current, over-voltage, and short-circuit protection provided by the AP9214L-AD-HSBR-7. Both are ROHS3 compliant with MSL rating of 1.

Packaging Consideration: The AP9214L-AD-HSBR-7 is supplied in Tape & Reel format. The AP9214L-AK-HSBR-7 substitute is available in Cut Tape format, which may affect automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can AP9214L-AK-HSBR-7 be used as a direct replacement for AP9214L-AD-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 footprint (6-UDFN Exposed Pad). The primary difference is packaging format: AP9214L-AD-HSBR-7 is supplied in Tape & Reel, while AP9214L-AK-HSBR-7 is supplied in Cut Tape. Verify that your assembly equipment can accommodate Cut Tape format.

Q: What is the difference between the Diodes AP9214 series and the Texas Instruments BQ297xx series? A: Both provide single-cell lithium ion/polymer battery protection with identical operating temperature ranges and RoHS3 compliance. The key differences are: (1) Package footprint—AP9214 uses 6-UDFN while BQ297xx uses 6-WSON (1.5x1.5), requiring PCB layout changes; (2) Fault protection—BQ297xx includes under-voltage detection in addition to over-current, over-voltage, and short-circuit protection; (3) Product status—BQ297xx parts are active with higher inventory, while AP9214 alternatives are obsolete.

Q: Can I use BQ29703DSER or BQ29717DSET without modifying my PCB? A: No. The 6-WSON (1.5x1.5) package has a different footprint than the 6-UDFN Exposed Pad used by AP9214L-AD-HSBR-7. PCB layout modification is required. However, both parts maintain the same operating temperature range (-40°C ~ 85°C) and RoHS3 compliance, ensuring functional compatibility after layout adjustment.

Q: Why are some AP9214 variants listed as obsolete? A: Product status reflects manufacturer lifecycle designation. Obsolete parts may have limited future availability. For new designs, prioritize active products such as AP9214L-AD-HSBR-7 (Diodes Incorporated) or BQ29703DSER and BQ29717DSET (Texas Instruments).

Q: Are all substitute parts ROHS3 compliant? A: Yes. All parts listed—AP9214L-AD-HSBR-7, AP9214L-AK-HSBR-7, AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, AP9214LA-AM-HSBR-7, BQ29703DSER, and BQ29717DSET—are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: What is the difference between AP9214L and AP9214LA variants? A: Both variants maintain identical electrical specifications, battery chemistry, cell count, fault protection, operating temperature range, and package footprint. Differences are limited to internal design revisions or manufacturing process changes. Both are suitable substitutes for the AP9214L-AD-HSBR-7.
