Key Parameters

Substitute Part Grouping Explanation

Substitution of the S-8244AAPFN-CEPT2G is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Manufacturer: ABLIC Inc.
• Base Product Number: S-8244
• Function: Battery Protection
• Battery Chemistry: Lithium Ion
• Number of Cells: 1 ~ 4
• Fault Protection: Over Voltage
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount
• Package / Case: 8-LSSOP, 8-MSOP (0.110", 2.80mm Width)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Variable Parameters (Allowed Differences):

• Supplier Device Package designation (8-MSOP, 8-TMSOP)
• Packaging format (Tape & Reel vs. other formats)
• Product Status (Last Time Buy vs. Active)
• Inventory availability

The identified substitute parts maintain all mandatory equivalence parameters while differing only in packaging designation and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

S-8244AAPFM-CEPT2U (MFR Recommended Substitute): This part is designated as the manufacturer-recommended substitute. It maintains full parametric equivalence with the main part across all critical battery protection specifications. The primary distinction is Active product status, indicating ongoing manufacturing and availability. The supplier device package designation changes from 8-MSOP to 8-TMSOP, though both maintain the same physical package dimensions (0.110", 2.80mm Width). This part carries ROHS3 compliance and REACH Unaffected status.

S-8244AALFN-CELT2G (Parametric Equivalent): This part provides parametric equivalence across all functional and electrical parameters. It maintains the original 8-MSOP supplier device package designation. However, it shares Last Time Buy status with the main part, indicating limited future availability. Selection of this part should be based on specific package designation requirements rather than long-term procurement strategy.

For applications requiring long-term component availability and supply chain continuity, S-8244AAPFM-CEPT2U is the appropriate selection due to its Active product status.

Frequently Asked Questions (FAQ)

Q: Can S-8244AAPFM-CEPT2U be used as a direct replacement for S-8244AAPFN-CEPT2G?

A: Yes. Both parts maintain identical functional specifications for battery protection, cell count support (1-4 cells), over-voltage fault protection, operating temperature range, and compliance certifications. The supplier device package designation differs (8-TMSOP vs. 8-MSOP), but physical package dimensions remain equivalent (0.110", 2.80mm Width).

Q: What is the difference between the MFR Recommended and Parametric Equivalent substitutes?

A: S-8244AAPFM-CEPT2U is designated as manufacturer-recommended and carries Active product status, ensuring ongoing availability. S-8244AALFN-CELT2G is a parametric equivalent with Last Time Buy status, indicating limited future manufacturing. Both maintain full functional equivalence.

Q: Are there package compatibility considerations when substituting these parts?

A: All three parts use surface mount technology with 8-pin configurations and identical physical dimensions (0.110", 2.80mm Width). PCB layout and footprint compatibility is maintained across all substitutes. The supplier device package designation (8-MSOP vs. 8-TMSOP vs. 8-WSSOP) reflects internal supplier classification but does not affect physical compatibility.

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

A: Yes. All parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). S-8244AAPFM-CEPT2U additionally carries REACH Unaffected status.

Q: Which substitute should be selected for new designs?

A: S-8244AAPFM-CEPT2U is the appropriate selection for new designs due to Active product status and assured long-term availability. This part maintains full parametric equivalence while providing supply chain continuity.
