Key Parameters

Substitute Part Grouping Explanation

Substitution for the S-8244AACFN-CECT2G is determined by the following critical parameters:

Functional Equivalence: Battery protection function for lithium ion chemistry with 1 to 4 cell support and over voltage fault protection.

Electrical Compatibility: Operating temperature range of -40°C ~ 85°C (TA), RoHS3 compliance, and MSL rating of 1 (Unlimited).

Mechanical Compatibility: Surface mount technology with 8-pin package configuration. Package variants include 8-LSSOP and 8-MSOP formats with 0.110" (2.80mm) width specification.

Manufacturer Consistency: All substitute parts are manufactured by ABLIC Inc. within the S-8244 series base product family.

Two substitute parts meet these criteria: S-8244AACFM-CECT2U (MFR Recommended) and S-8244AALFN-CELT2G (Parametric Equivalent).

Parameter Comparison

Engineering Selection Recommendations

S-8244AACFM-CECT2U (MFR Recommended Substitute): This part is designated as the manufacturer-recommended alternative. It maintains all functional and electrical parameters identical to the main part. The primary distinction is the supplier device package designation (8-TMSOP versus 8-MSOP) and the case variant (8-WSSOP versus 8-LSSOP). The part status is Active, providing superior long-term availability compared to the Last Time Buy status of the main part. This substitute is the preferred choice for new designs and ongoing production requiring extended supply assurance.

S-8244AALFN-CELT2G (Parametric Equivalent): This part provides functional and electrical equivalence with identical package and case specifications to the main part (8-LSSOP, 8-MSOP). Both parts share the same supplier device package (8-MSOP) and Last Time Buy status. This substitute is suitable for direct replacement in existing designs where package compatibility is critical. Higher inventory availability (3938 Pcs) compared to the main part (877 Pcs) supports immediate procurement needs.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the S-8244AACFN-CECT2G?

A: Substitution is determined by matching function (battery protection), battery chemistry (lithium ion), cell count support (1 to 4 cells), fault protection type (over voltage), operating temperature range (-40°C ~ 85°C), compliance status (ROHS3), and package configuration (8-pin surface mount with 0.110" width). All three parts meet these criteria.

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

A: The MFR Recommended substitute (S-8244AACFM-CECT2U) has Active product status and uses an 8-TMSOP supplier package with 8-WSSOP case variant. The Parametric Equivalent (S-8244AALFN-CELT2G) maintains identical package specifications (8-MSOP supplier package, 8-LSSOP case) to the main part but retains Last Time Buy status. The MFR Recommended option provides better long-term availability.

Q: Are there package compatibility concerns between these substitutes?

A: The main part and S-8244AALFN-CELT2G use identical package specifications (8-LSSOP, 8-MSOP with 0.110" width). The S-8244AACFM-CECT2U uses 8-WSSOP and 8-TMSOP variants. While all are 8-pin surface mount packages with the same width specification, PCB layout and footprint compatibility should be verified for the MFR Recommended substitute if direct board-level replacement is required.

Q: Why is the main part classified as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has announced limited future availability. This classification makes identifying active substitutes essential for supply chain continuity. The MFR Recommended substitute with Active status is the preferred long-term solution.

Q: What compliance certifications apply to all three parts?

A: All three parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. The MFR Recommended substitute additionally carries REACH Unaffected status.
