AP9211S-AF-HAC-7 Equivalent & Substitute Parts

Part Overview

The AP9211S-AF-HAC-7 is a Battery Protection IC for single-cell lithium-ion applications manufactured by Diodes Incorporated. This device provides over-current and over-voltage fault protection in a 6-UDFN surface-mount package. The part is currently listed as obsolete, making equivalent substitute parts necessary for ongoing design support and production continuity. Substitute parts within the AP9211 series maintain identical electrical and mechanical specifications while offering alternative packaging formats and active product status options.

Substitute Part Grouping Explanation

Substitution within the AP9211 series is determined by strict equivalence across the following parameters:

Battery Chemistry: Lithium Ion (all variants)
Number of Cells: 1 (all variants)
Fault Protection: Over Current, Over Voltage (all variants)
Operating Temperature Range: -40°C ~ 85°C (all variants)
Mounting Type: Surface Mount (all variants)
Package / Case: 6-UDFN Exposed Pad (all variants)
Supplier Device Package: U-DFN2030-6 (Type C) (all variants)
RoHS Status: ROHS3 Compliant (all variants)
Moisture Sensitivity Level: 1 (Unlimited) (all variants)

Substitute parts differ only in packaging format (Cut Tape vs. Tape & Reel) and product status (Active vs. Obsolete). These differences do not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

For new designs or production continuation, active product status variants are preferred: AP9211S-AB-HAC-7, AP9211S-AC-HAC-7, and AP9211S-AM-HAC-7. All three maintain full electrical and mechanical equivalence to AP9211S-AF-HAC-7 while offering long-term availability assurance.

Packaging format selection depends on assembly requirements. Tape & Reel (TR) packaging is standard for high-volume automated assembly. Cut Tape (CT) packaging is suitable for lower-volume or manual assembly operations.

All substitute parts carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can AP9211S-AB-HAC-7 replace AP9211S-AF-HAC-7 directly in production?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format (Tape & Reel vs. Cut Tape) and product status (Active vs. Obsolete). Direct substitution is valid for any application using the original part.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) is supplied in individual strips suitable for manual or low-volume pick-and-place operations. Tape & Reel (TR) is supplied on continuous reels optimized for high-speed automated assembly equipment. Electrical and mechanical specifications are identical.

Q: Are all AP9211 variants compatible with single-cell lithium-ion battery protection applications?

A: Yes. All listed variants provide identical over-current and over-voltage protection for single-cell lithium-ion batteries across the -40°C to 85°C operating temperature range.

Q: Why is AP9211S-AF-HAC-7 marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. Active variants within the AP9211 series provide equivalent functionality with ongoing supply assurance.

Q: Does packaging format affect PCB layout or thermal performance?

A: No. Both Cut Tape and Tape & Reel variants use the identical 6-UDFN Exposed Pad package (U-DFN2030-6 Type C). PCB footprint, thermal characteristics, and electrical performance are unchanged.

Q: Are all variants ROHS3 compliant?

A: Yes. All listed AP9211 variants carry ROHS3 compliance and REACH unaffected status.
