Key Parameters

Substitute Part Grouping Explanation

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

Primary Substitution Criteria:

• Function: Battery Protection IC
• Battery Chemistry: Lithium Ion/Polymer
• Number of Cells: Single Cell (1)
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 85°C (TA)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Acceptable Variations:

• Package / Case format (different surface mount packages permitted)
• Fault Protection scope (additional protection features acceptable)
• Supplier Device Package (alternative surface mount packages acceptable)
• Product Status (Active or Obsolete both acceptable if other parameters match)

The two qualified substitute parts meet all primary criteria while offering alternative packaging configurations suitable for different PCB layout requirements.

Parameter Comparison

Engineering Selection Recommendations

S-8211CDN-M5T1U (Primary Selection) Select this part when SOT-23-5 packaging is specified in the design. Active product status ensures long-term availability and manufacturer support. ROHS3 compliance and REACH Unaffected status meet regulatory requirements.

AP9214L-AK-HSBR-7 (Alternative - Packaging Consideration) This substitute offers 6-UDFN Exposed Pad packaging with expanded fault protection including Over Voltage detection. Product status is Obsolete; use only when existing inventory is available and long-term procurement is not required. Higher inventory (9600 units) provides short-term availability. ROHS3 compliance and REACH Unaffected status maintained.

BQ29729DSER (Recommended Alternative - Active Status) This substitute provides 6-WSON packaging with comprehensive fault protection including Over/Under Voltage detection. Active product status ensures ongoing manufacturer support and long-term availability. Inventory of 6371 units supports sustained procurement. ROHS3 compliance and REACH Unaffected status maintained. Select this part when long-term supply chain stability is prioritized.

Frequently Asked Questions (FAQ)

Q: Can AP9214L-AK-HSBR-7 be used as a direct replacement for S-8211CDN-M5T1U? A: Electrical substitution is valid based on matching battery chemistry, cell count, operating temperature, and protection function. However, package format differs (6-UDFN vs. SOT-23-5), requiring PCB layout modification. Obsolete product status limits future availability.

Q: What is the primary difference between the two substitute parts? A: AP9214L-AK-HSBR-7 uses 6-UDFN packaging with Over Voltage protection. BQ29729DSER uses 6-WSON packaging with Over/Under Voltage protection. Both are electrically qualified substitutes with identical operating temperature ranges and compliance certifications.

Q: Is BQ29729DSER preferable to AP9214L-AK-HSBR-7? A: BQ29729DSER is preferable for new designs due to Active product status, ensuring long-term availability and manufacturer support. AP9214L-AK-HSBR-7 Obsolete status makes it suitable only for existing inventory utilization.

Q: Do all three parts require identical PCB footprints? A: No. S-8211CDN-M5T1U uses SOT-23-5 footprint. AP9214L-AK-HSBR-7 requires 6-UDFN footprint. BQ29729DSER requires 6-WSON footprint. Each substitute necessitates distinct PCB layout modifications.

Q: Are all three parts ROHS3 compliant? A: Yes. All three parts are ROHS3 Compliant with REACH Unaffected status, meeting current regulatory requirements for electronic components.

Q: What protection features does each part provide? A: S-8211CDN-M5T1U provides Over Current and Short Circuit protection. AP9214L-AK-HSBR-7 adds Over Voltage protection. BQ29729DSER provides Over Current, Over/Under Voltage, and Short Circuit protection.
