Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following parameters:

Battery Chemistry: Lithium Ion/Polymer
Number of Cells: 1
Fault Protection: Over Current, Short Circuit (minimum)
Package / Case: SOT-23-6
Mounting Type: Surface Mount
Operating Temperature Range: -40°C ~ 85°C (TA)

Product Status: Active

Parametric equivalents maintain all core electrical and mechanical specifications. The S-8261ACAMD-G4AT2G has four parametric equivalents within the ABLIC Inc. product line that differ only in packaging format (Tape & Reel vs. Cut Tape) or base series designation. The BQ29706DSER from Texas Instruments is classified as a similar part due to package case differences (6-WSON vs. SOT-23-6) while maintaining equivalent electrical function and fault protection capabilities.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, confirming suitability for current production environments. The four ABLIC Inc. parametric equivalents (S-8261AAJMD-G2JT2G, S-8261AAJMD-G2JT2U, S-8240ACS-M6T1U, S-8240ADZ-M6T1U) are direct functional replacements with identical electrical specifications and SOT-23-6 packaging. Selection between these parts is determined by packaging format requirements: Cut Tape (CT) for lower-volume applications or Tape & Reel (TR) for automated assembly processes.

The BQ29706DSER from Texas Instruments provides equivalent single-cell Lithium Ion/Polymer protection with additional Over/Under Voltage fault detection. The 6-WSON package differs from SOT-23-6, requiring PCB layout and footprint modifications. This part is suitable only when design specifications accommodate the alternative package geometry and when the enhanced voltage protection feature is required.

Frequently Asked Questions (FAQ)

Q: Can S-8261AAJMD-G2JT2G replace S-8261ACAMD-G4AT2G directly?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, operating temperature range, and SOT-23-6 packaging. The difference is packaging format: S-8261AAJMD-G2JT2G is supplied in Cut Tape (CT) while S-8261ACAMD-G4AT2G is Tape & Reel (TR). Selection depends on assembly process requirements.

Q: What is the difference between S-8240 and S-8261 series parts?

A: Both series provide single-cell Lithium Ion/Polymer battery protection with identical fault protection (Over Current, Short Circuit), operating temperature, and SOT-23-6 packaging. They are functionally equivalent and interchangeable based on the parameters provided.

Q: Can BQ29706DSER be used as a drop-in replacement?

A: BQ29706DSER is functionally equivalent for battery protection but uses 6-WSON packaging instead of SOT-23-6. This requires PCB footprint redesign and is not a direct drop-in replacement. Additionally, BQ29706DSER includes Over/Under Voltage protection, which may or may not be required for your application.

Q: Which substitute part has the highest inventory availability?

A: S-8261AAJMD-G2JT2G has 13,700 pieces in stock, providing the highest availability among all listed equivalents.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and Active product status, confirming regulatory compliance for current production designs.
