Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S-8211CDD-M5T1U is determined by the following critical parameters:

• Function: Battery Protection IC for single-cell applications
• Battery Chemistry: Lithium Ion/Polymer support
• Number of Cells: Single-cell (1 cell) configuration
• Fault Protection: Minimum requirement of Over Current and Short Circuit protection
• Operating Temperature: -40°C to 85°C range
• Mounting Type: Surface Mount
• Product Status: Active
• Compliance: ROHS3 Compliant, REACH Unaffected

The BQ29717DSET from Texas Instruments meets these substitution criteria. While it employs a different package format (6-WSON versus SOT-23-5), it maintains functional equivalence for single-cell Lithium Ion/Polymer battery protection with enhanced fault protection capabilities (Over Current, Over/Under Voltage, Short Circuit).

Parameter Comparison

Engineering Selection Recommendations

Both the S-8211CDD-M5T1U and BQ29717DSET are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these parts depends on package footprint constraints and PCB layout requirements. The S-8211CDD-M5T1U uses SOT-23-5 packaging, while the BQ29717DSET uses 6-WSON (1.5x1.5) packaging. The BQ29717DSET provides additional over/under voltage protection beyond the base requirements of the S-8211CDD-M5T1U. Both parts maintain identical operating temperature ranges and moisture sensitivity ratings.

Frequently Asked Questions (FAQ)

Q: Can the BQ29717DSET directly replace the S-8211CDD-M5T1U on the same PCB?

A: Direct PCB replacement is not possible due to different package formats. The S-8211CDD-M5T1U uses SOT-23-5 (5-pin) while the BQ29717DSET uses 6-WSON (1.5x1.5) (6-pin). PCB redesign is required for footprint accommodation.

Q: Are both parts suitable for the same battery chemistry applications?

A: Yes. Both parts are designed for Lithium Ion/Polymer single-cell battery protection and operate within the same temperature range (-40°C to 85°C).

Q: What is the functional difference between these parts?

A: The S-8211CDD-M5T1U provides Over Current and Short Circuit protection. The BQ29717DSET provides Over Current, Over/Under Voltage, and Short Circuit protection, offering enhanced protection capabilities.

Q: Do both parts meet current compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have MSL Rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.
