AP9214LA-AD-HSBR-7 Equivalent & Substitute Parts

Part Overview

The AP9214LA-AD-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 994 units in stock.

Substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design flexibility allows for functionally equivalent alternatives from the same manufacturer.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP9214LA-AD-HSBR-7 is determined by the following criteria:

Primary Substitution Parameters:

• Function: Battery Protection
• Battery Chemistry: Lithium Ion/Polymer
• Number of Cells: 1
• Fault Protection: Over Current, Over Voltage, Short Circuit
• Package / Case: 6-UDFN Exposed Pad
• Supplier Device Package: U-DFN2535-6
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Variation Parameter:

• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) — affects supply chain and manufacturing processes but does not alter electrical or mechanical compatibility

Diodes Incorporated AP9214 series variants (AP9214L-AK-HSBR-7, AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, AP9214LA-AM-HSBR-7) meet all primary substitution criteria. The Texas Instruments BQ29717DSET is a manufacturer-recommended alternative that maintains functional equivalence with a different package format (6-WSON instead of 6-UDFN).

Parameter Comparison

Engineering Selection Recommendations

For Active Production Designs: The AP9214LA-AD-HSBR-7 remains the primary selection as an active product with ROHS3 compliance and unlimited moisture sensitivity rating. This part maintains long-term availability and supply chain stability.

For Packaging Format Flexibility: The AP9214L-AK-HSBR-7 provides identical electrical and mechanical specifications in Cut Tape format, suitable for applications requiring individual component handling or lower-volume assembly processes. Despite obsolete status, current inventory of 9600 units supports near-term production needs.

For Tape & Reel Alternatives: AP9214L-AN-HSB-7 and AP9214LA-AH-HSB-7 are functionally equivalent alternatives in Tape & Reel packaging. Both are obsolete but maintain adequate inventory levels. AP9214LA-AM-HSBR-7 offers the same specifications with 3999 units available.

For Cross-Manufacturer Substitution: BQ29717DSET from Texas Instruments is an active product that maintains functional equivalence with identical operating temperature range, single-cell lithium ion/polymer protection, and ROHS3 compliance. The 6-WFDFN package differs from the 6-UDFN format and requires PCB layout verification before implementation. This part includes under-voltage protection in addition to over-current, over-voltage, and short-circuit protection.

Frequently Asked Questions (FAQ)

Q: Can AP9214L-AK-HSBR-7 be used as a direct replacement for AP9214LA-AD-HSBR-7?

A: Yes. Both parts share identical electrical specifications, operating temperature range, fault protection capabilities, and 6-UDFN package format. The difference is packaging format: Cut Tape (CT) versus Tape & Reel (TR). PCB footprint and electrical performance are equivalent. Verify your assembly process accommodates Cut Tape format.

Q: What is the difference between AP9214LA-AH-HSB-7 and AP9214LA-AM-HSBR-7?

A: Both parts are functionally identical with matching electrical specifications, operating temperature, and 6-UDFN package. The part number suffix indicates internal manufacturing variations that do not affect performance or compatibility. Both are obsolete status with adequate inventory.

Q: Can BQ29717DSET replace AP9214LA-AD-HSBR-7 in existing designs?

A: BQ29717DSET provides equivalent battery protection functionality for single-cell lithium ion/polymer applications with identical operating temperature range and ROHS3 compliance. However, the package format differs (6-WFDFN versus 6-UDFN), requiring PCB layout redesign and footprint verification. BQ29717DSET includes under-voltage protection as an additional feature. This substitution requires design validation before implementation.

Q: Why are most AP9214 variants marked as obsolete?

A: Obsolete status indicates these parts are no longer in active production. However, current inventory levels remain substantial, supporting existing supply chains and production schedules. The AP9214LA-AD-HSBR-7 maintains active status for new designs requiring long-term availability assurance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts, including BQ29717DSET, maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), meeting environmental and regulatory requirements for current manufacturing standards.

Q: What determines whether a part can substitute for AP9214LA-AD-HSBR-7?

A: Substitution eligibility requires matching function (battery protection), battery chemistry (lithium ion/polymer), cell count (1), fault protection capabilities (over-current, over-voltage, short-circuit), operating temperature range (-40°C ~ 85°C), surface mount capability, and ROHS3 compliance. Package format variations (Tape & Reel, Cut Tape) and manufacturer differences are acceptable provided mechanical footprint compatibility is verified.
