Substitute Part Grouping Explanation

Substitute parts for the AP9211S-AK-HAC-7 are determined by strict equivalence across the following parameters:

Battery Chemistry: Lithium Ion
Number of Cells: 1
Fault Protection: Over Current, Over Voltage
Operating Temperature Range: -40°C ~ 85°C (TA)
Mounting Type: Surface Mount
Package / Case: 6-UDFN Exposed Pad

Engineering Selection Recommendations

For new designs and production continuity, prioritize Active status parts: AP9211S-AB-HAC-7, AP9211S-AC-HAC-7, and AP9211S-AM-HAC-7. These variants maintain full electrical and mechanical equivalence to the obsolete AP9211S-AK-HAC-7 while ensuring long-term availability and supply chain stability.

All substitute parts maintain ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements. Packaging format selection (Tape & Reel or Cut Tape) depends on assembly process requirements and does not affect functional performance.

Frequently Asked Questions (FAQ)

Q: Can AP9211S-AB-HAC-7, AP9211S-AC-HAC-7, or AP9211S-AM-HAC-7 directly replace AP9211S-AK-HAC-7?

A: Yes. All three parts are parametric equivalents sharing identical electrical specifications, operating temperature range, fault protection capabilities, and package configuration. The difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel).

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

A: Tape & Reel (TR) and Cut Tape (CT) are distribution formats that affect handling and assembly processes. Both formats contain the same component in the same 6-UDFN Exposed Pad package. Selection depends on manufacturing equipment compatibility and volume requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental regulations.

Q: Why is AP9211S-AK-HAC-7 marked as Obsolete?

A: Obsolete status indicates the part is no longer in active production. Active equivalent variants are available to support ongoing applications without functional compromise.

Q: Can I use obsolete variants like AP9211S-AD-HAC-7 or AP9211S-AF-HAC-7 as substitutes?

A: Obsolete variants are parametric equivalents but carry supply risk. Active status parts (AP9211S-AB-HAC-7, AP9211S-AC-HAC-7, AP9211S-AM-HAC-7) are recommended for new designs and production orders to ensure long-term availability.
