Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP9214LA-AM-HSB-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)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Substitution Criteria:

• Package / Case: 6-UDFN Exposed Pad or equivalent mechanical footprint
• Supplier Device Package: U-DFN2535-6 or functionally equivalent
• Product Status: Active or Obsolete (both acceptable for equivalent function)

Diodes Incorporated AP9214 series variants (AP9214L-AK-HSBR-7, AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, AP9214LA-AM-HSBR-7) meet all primary and secondary criteria and are direct parametric equivalents. The Texas Instruments BQ29733DSET is a manufacturer-recommended alternative that meets all primary criteria but uses a different package format (6-WSON 1.5x1.5) and includes under-voltage protection in addition to the specified fault protections.

Parameter Comparison

Engineering Selection Recommendations

Within-Manufacturer Substitutes (Diodes Incorporated AP9214 Series):

The AP9214L-AK-HSBR-7, AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, and AP9214LA-AM-HSBR-7 are direct parametric equivalents to the AP9214LA-AM-HSB-7. All variants share identical electrical specifications, operating temperature range, fault protection capabilities, and package footprint. Selection among these variants is determined by packaging format availability and product status requirements. The AP9214L-AK-HSBR-7 is available in Cut Tape (CT) format with the highest inventory (9600 units). The AP9214LA-AM-HSBR-7 and AP9214L-AN-HSB-7 are available in Tape & Reel (TR) format. All Diodes Incorporated variants are ROHS3 compliant with MSL 1 rating.

Cross-Manufacturer Substitute (Texas Instruments BQ29733DSET):

The BQ29733DSET is a manufacturer-recommended alternative from Texas Instruments. This part maintains electrical equivalence for single-cell Lithium Ion/Polymer battery protection with identical operating temperature range (-40°C ~ 85°C) and ROHS3 compliance. The BQ29733DSET includes under-voltage protection in addition to over-current, over-voltage, and short-circuit protection. The package format differs (6-WSON 1.5x1.5 versus 6-UDFN Exposed Pad), requiring PCB layout verification for mechanical compatibility. The BQ29733DSET is currently Active in product status with 5970 units in inventory.

Product Status Considerations:

The AP9214LA-AM-HSB-7 is Active. The Diodes Incorporated variants AP9214L-AK-HSBR-7, AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, and AP9214LA-AM-HSBR-7 are marked Obsolete. The BQ29733DSET is Active. For long-term supply chain stability, Active status parts are preferred; however, Obsolete parts remain functionally equivalent and may be selected based on inventory availability and immediate project requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute AP9214LA-AM-HSB-7 with any of the Diodes Incorporated AP9214 variants?

A: Yes. All AP9214 series variants (AP9214L-AK-HSBR-7, AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, AP9214LA-AM-HSBR-7) are parametric equivalents. They share identical electrical specifications, fault protection capabilities, operating temperature range, and package footprint. Selection is based on packaging format (Tape & Reel or Cut Tape) and inventory availability.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel (TR) packaging is supplied on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) packaging is supplied as individual segments cut from the tape, suitable for lower-volume or manual assembly operations. Both formats contain identical components; the difference is in delivery and handling format only.

Q: Can I use the BQ29733DSET as a direct replacement for AP9214LA-AM-HSB-7?

A: The BQ29733DSET is electrically equivalent for single-cell Lithium Ion/Polymer battery protection with identical operating temperature range and fault protection capabilities. However, the package format differs (6-WSON 1.5x1.5 versus 6-UDFN Exposed Pad). PCB layout and footprint verification is required before substitution. The BQ29733DSET includes under-voltage protection as an additional feature.

Q: What does "Obsolete" product status mean for the AP9214 variants?

A: Obsolete status indicates the manufacturer has discontinued active production and support for that specific part number variant. However, Obsolete parts remain functionally equivalent and may be available through inventory channels. For new designs requiring long-term supply assurance, Active status parts (AP9214LA-AM-HSB-7 or BQ29733DSET) are recommended.

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, and BQ29733DSET) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What fault protections does each part provide?

A: All Diodes Incorporated AP9214 variants provide over-current, over-voltage, and short-circuit protection. The Texas Instruments BQ29733DSET provides over-current, over-voltage, under-voltage, and short-circuit protection. The additional under-voltage protection in the BQ29733DSET does not prevent substitution but represents an enhanced feature set.

Q: Which substitute part has the highest inventory availability?

A: The AP9214L-AK-HSBR-7 has the highest inventory with 9600 units in stock. The BQ29733DSET has 5970 units, AP9214LA-AH-HSB-7 has 5378 units, AP9214LA-AM-HSBR-7 has 3999 units, and AP9214L-AN-HSB-7 has 3898 units.
