Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S-8244AAPFN-CEPT2U is determined by the following critical parameters:

Core Functional Parameters:

• Battery Chemistry: Lithium Ion
• Number of Cells: 1 ~ 4
• Fault Protection Type: Over Voltage
• Operating Temperature Range: -40°C ~ 85°C (TA)

Physical & Compliance Parameters:

• Manufacturer: ABLIC Inc.
• Mounting Type: Surface Mount
• Base Product Number: S-8244
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts S-8244AAPFM-CEPT2U and S-8244AALFN-CELT2G maintain identical functional specifications and compliance certifications. Variations in supplier device package designation (8-TMSOP vs. 8-MSOP) and product status do not affect electrical equivalence within the allowed parameter set.

Parameter Comparison

Engineering Selection Recommendations

S-8244AAPFM-CEPT2U is the primary recommended substitute. This part maintains full parametric equivalence with the main part while offering Active product status, ensuring continued availability and supply chain stability. The 8-TMSOP supplier device package is functionally equivalent within the 8-MSOP case family specification.

S-8244AALFN-CELT2G is a secondary parametric equivalent. While functionally identical, this part carries Last Time Buy status identical to the main part, offering no supply advantage. Selection of this substitute should be limited to applications where specific packaging or sourcing requirements necessitate its use.

Both substitutes maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can S-8244AAPFM-CEPT2U be used as a direct replacement for S-8244AAPFN-CEPT2U?

A: Yes. Both parts share identical functional specifications for battery protection (Lithium Ion, 1-4 cells, over-voltage protection), operating temperature range (-40°C to 85°C), and compliance certifications (ROHS3). The difference in supplier device package designation (8-TMSOP vs. 8-MSOP) does not affect electrical equivalence.

Q: What is the difference between 8-MSOP and 8-TMSOP packages?

A: Both designations refer to 8-pin Micro Small Outline Package variants with 0.110" width and 2.80mm body width. The functional pinout and electrical characteristics remain equivalent. Physical footprint compatibility should be verified against PCB design specifications.

Q: Why is S-8244AAPFN-CEPT2U marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued or is discontinuing production of this specific part number. Substitute parts with Active status should be prioritized for new designs to ensure long-term supply availability.

Q: Are all three parts interchangeable in existing designs?

A: Electrical interchangeability is confirmed across all three parts. PCB layout compatibility depends on package footprint alignment. Designs using 8-MSOP footprints are compatible with both S-8244AAPFN-CEPT2U and S-8244AALFN-CELT2G. Designs requiring 8-TMSOP footprint compatibility should use S-8244AAPFM-CEPT2U.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting standard industrial manufacturing and storage requirements.
