AP9214LA-AC-HSB-7 Equivalent & Substitute Parts

Part Overview

The AP9214LA-AC-HSB-7 is a Battery Protection IC for single-cell Lithium Ion/Polymer applications manufactured by Diodes Incorporated. This Surface Mount device in 6-UDFN Exposed Pad packaging provides over-current, over-voltage, and short-circuit protection. The part is currently Active in product status with 976 units in stock. Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when inventory constraints necessitate sourcing from alternative stock positions.

Substitute Part Grouping Explanation

Substitution eligibility for the AP9214LA-AC-HSB-7 is determined by the following parameters:

Manufacturer: All substitutes must be from Diodes Incorporated
Function: Battery Protection for single-cell Lithium Ion/Polymer chemistry
Fault Protection: Over Current, Over Voltage, Short Circuit protection capability
Package / Case: 6-UDFN Exposed Pad (U-DFN2535-6)
Operating Temperature Range: -40°C ~ 85°C (TA)
Mounting Type: Surface Mount
Compliance: ROHS3 Compliant, REACH Unaffected

Packaging format (Tape & Reel vs. Cut Tape) and product status (Active vs. Obsolete) do not restrict substitution eligibility but may affect availability and lead times. All listed substitutes share identical electrical specifications and mechanical compatibility with the main part number.

Engineering Selection Recommendations

Primary Selection: AP9214LA-AC-HSB-7 is the recommended choice as the only Active product status part in this family. It provides current availability with 976 units in stock and maintains full compliance with ROHS3 and REACH requirements.

Alternative Selections: The four substitute parts (AP9214L-AK-HSBR-7, AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, AP9214LA-AM-HSBR-7) are electrically and mechanically equivalent and carry identical compliance certifications. However, all four are classified as Obsolete. Selection among these alternatives should be based on packaging format requirements and inventory availability:

Tape & Reel (TR) Format: AP9214L-AN-HSB-7, AP9214LA-AH-HSB-7, or AP9214LA-AM-HSBR-7
Cut Tape (CT) Format: AP9214L-AK-HSBR-7

Obsolete parts may have extended lead times or limited future availability. Verify long-term supply chain requirements before committing to obsolete alternatives.

Frequently Asked Questions (FAQ)

Q: Can I substitute AP9214L-AK-HSBR-7 (Cut Tape) for AP9214LA-AC-HSB-7 (Tape & Reel)?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. Cut Tape is suitable for manual or semi-automated assembly, while Tape & Reel is optimized for automated pick-and-place equipment. Verify your assembly process requirements before substituting.

Q: Why are the substitute parts marked as Obsolete?

A: Product status reflects manufacturer lifecycle classification. Obsolete status does not indicate functional deficiency or compliance issues. These parts remain ROHS3 Compliant and REACH Unaffected. Obsolete classification typically indicates the manufacturer has discontinued active production or support.

Q: Are all substitute parts pin-compatible with the main part?

A: Yes. All parts use the 6-UDFN Exposed Pad (U-DFN2535-6) package with identical pinout and electrical characteristics. Direct PCB layout substitution is possible without design modification.

Q: What is the difference between AP9214LA-AC-HSB-7 and AP9214L-AN-HSB-7?

A: Both parts provide identical battery protection functionality for single-cell Lithium Ion/Polymer applications. The difference is in the part number suffix, which reflects internal manufacturer coding. Electrical performance, package, and compliance are equivalent.

Q: Can I mix packaging formats in the same production run?

A: Packaging format (Tape & Reel vs. Cut Tape) affects assembly process compatibility, not electrical performance. Mixing formats in a single production run is possible if your assembly equipment supports both formats. Verify with your manufacturing partner.

Q: Is inventory level a factor in substitution eligibility?

A: No. Inventory levels reflect current stock position only and do not affect electrical or mechanical compatibility. However, higher inventory parts may offer better availability and shorter lead times.
