Key Parameters

Substitute Part Grouping Explanation

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

Core Functional 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)

Physical & Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Mounting Type: Surface Mount

Substitute parts are grouped into two categories:

Category 1: Parametric Equivalents (Diodes Incorporated AP9214 Series) These parts share identical functional specifications, battery chemistry, cell count, and fault protection capabilities. They differ only in packaging format (Tape & Reel vs. Cut Tape) or product status (Obsolete vs. Active). All maintain the same 6-UDFN Exposed Pad package footprint and electrical performance.

Category 2: Manufacturer Recommended Alternatives (Texas Instruments BQ Series) These parts provide equivalent battery protection functionality for single-cell Lithium Ion/Polymer applications with identical operating temperature ranges and compliance certifications. They utilize a different package format (6-WSON 1.5x1.5) but maintain functional compatibility through equivalent fault protection mechanisms.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Status Requirement: Select AP9214L-AJ-HSB-7 (primary) or transition to BQ29703DSER or BQ29717DSET for long-term supply assurance. All three parts maintain Active product status with ROHS3 compliance and unlimited moisture sensitivity rating.

For Diodes Incorporated AP9214 Series Continuity: AP9214L-AJ-HSB-7 is the recommended primary selection. All parametric equivalents (AP9214L-AK-HSBR-7, AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, AP9214LA-AM-HSBR-7) provide identical electrical and functional performance. Selection among these should be based on packaging format availability (Tape & Reel vs. Cut Tape) and inventory requirements.

For Cross-Manufacturer Substitution: BQ29703DSER and BQ29717DSET from Texas Instruments provide equivalent battery protection functionality with identical operating temperature ranges and compliance certifications. These parts utilize 6-WSON packaging instead of 6-UDFN, requiring PCB layout verification for footprint compatibility. Both maintain Active product status with superior inventory availability (18025 and 1854 units respectively).

For Supply Chain Optimization: BQ29703DSER offers the highest inventory level (18025 units) among all qualified substitutes, supporting extended production runs and reducing supply chain risk.

Frequently Asked Questions (FAQ)

Q: Can AP9214L-AJ-HSB-7 be directly replaced with AP9214L-AK-HSBR-7? A: Yes. Both parts share identical electrical specifications, battery chemistry, fault protection capabilities, and operating temperature ranges. The difference is packaging format: AP9214L-AJ-HSB-7 is supplied in Tape & Reel format while AP9214L-AK-HSBR-7 is Cut Tape. PCB footprint and electrical performance are equivalent.

Q: What is the difference between Diodes Incorporated AP9214 series and Texas Instruments BQ29703/BQ29717? A: Both provide single-cell Lithium Ion/Polymer battery protection with identical operating temperature ranges (-40°C to 85°C) and fault protection mechanisms. The primary difference is package format: AP9214 uses 6-UDFN Exposed Pad while BQ series uses 6-WSON (1.5x1.5). PCB layout and component placement must be verified for cross-manufacturer substitution.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts (AP9214L-AK-HSBR-7, AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, AP9214LA-AM-HSBR-7, BQ29703DSER, BQ29717DSET) maintain ROHS3 compliance with Moisture Sensitivity Level 1 (Unlimited).

Q: Which substitute parts have Active product status? A: AP9214L-AJ-HSB-7 (primary), BQ29703DSER, and BQ29717DSET maintain Active status. All other Diodes Incorporated AP9214 variants are Obsolete.

Q: Can I use BQ29703DSER or BQ29717DSET as direct drop-in replacements? A: Electrical functionality is equivalent for single-cell Lithium Ion/Polymer battery protection. However, package format differs (6-WSON vs. 6-UDFN), requiring PCB layout verification and potential redesign of component placement and routing.

Q: What is the difference between BQ29703DSER and BQ29717DSET? A: Both parts provide equivalent battery protection functionality with identical operating temperature ranges and compliance certifications. Selection should be based on inventory availability and specific application requirements. BQ29703DSER has higher inventory (18025 units vs. 1854 units).
