Substitute Part Grouping Explanation

Substitution eligibility for the S-8204BAC-TCT1U is determined by the following critical parameters:

• Battery Chemistry: Lithium Ion
• Number of Cells: 3 ~ 4 cell configuration
• Fault Protection: Over Current and Short Circuit protection capability
• Package / Case: 16-TSSOP mechanical form factor
• Supplier Device Package: 16-TSSOP-A pinout compatibility
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount

The identified substitute part S-8204AAL-TCT1U matches all critical electrical and mechanical parameters. This part is manufactured by the same supplier (ABLIC Inc.) and maintains identical functional specifications for lithium ion battery protection in 3 to 4 cell applications.

Parameter Comparison

Engineering Selection Recommendations

The S-8204BAC-TCT1U is the preferred selection for new designs due to its Active product status. This designation indicates ongoing manufacturer support, continued availability, and compliance with current industry standards.

The S-8204AAL-TCT1U is classified as Not For New Designs. While this part maintains full electrical and mechanical compatibility with the S-8204BAC-TCT1U, its product status indicates that ABLIC Inc. does not recommend its use in new development projects. This part remains suitable for legacy system maintenance, repair operations, or applications where existing inventory must be utilized.

Both parts maintain identical RoHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Can S-8204AAL-TCT1U be used as a direct replacement for S-8204BAC-TCT1U in new designs?

A: Both parts are electrically and mechanically equivalent. However, S-8204AAL-TCT1U carries a Not For New Designs status. New product development should specify S-8204BAC-TCT1U to ensure long-term manufacturer support and availability.

Q: Are the pinout configurations identical between these parts?

A: Yes. Both parts use the 16-TSSOP-A supplier device package, ensuring identical pin assignments and PCB layout compatibility.

Q: What is the significance of the product status difference?

A: Active status indicates the manufacturer actively supports the part with ongoing production and supply commitments. Not For New Designs status signals that the manufacturer is transitioning away from this part number, though existing inventory may remain available for a limited period.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both S-8204BAC-TCT1U and S-8204AAL-TCT1U are ROHS3 Compliant, REACH Unaffected, and operate across the identical temperature range of -40°C to 85°C.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Identical package specifications (16-TSSOP, 0.173" width, 4.40mm) and pinout (16-TSSOP-A) ensure mechanical and electrical interchangeability without PCB modifications.
