Substitute Part Grouping Explanation
Substitution eligibility for the S-8241ADVMC-GDVT2G is determined by the following critical parameters:
- Battery Chemistry: Lithium Ion/Polymer
- Number of Cells: Single-cell (1 cell)
- Fault Protection: Over Current and Over Voltage minimum
- Operating Temperature Range: -40°C ~ 85°C (TA)
- Mounting Type: Surface Mount
- RoHS Compliance: ROHS3 Compliant
Substitute parts are grouped into two categories:
Parametric Equivalents maintain identical electrical specifications and package form factors (SOT-23-5). These parts are direct pin-compatible replacements with the same protection features.
Similar Parts provide equivalent functional protection for single-cell lithium ion/polymer batteries but may differ in package type (6-UDFN, 6-WSON) or include additional fault protection features (short-circuit protection, under-voltage protection). These require PCB layout modifications but deliver equivalent or enhanced protection functionality.

Engineering Selection Recommendations
For Direct Replacement (Pin-Compatible, No Layout Changes):
S-8241ABPMC-GBPT2G and S-8241ABKMC-GBKT2G are parametric equivalents from ABLIC Inc. Both maintain SOT-23-5 packaging, identical electrical specifications, and ROHS3 compliance. Both are classified as "Not For New Designs" but remain available in production quantities. S-8241ABPMC-GBPT2G offers the highest inventory availability (23,400 pcs).
For Active Product Transition:
AP9101CAK-ACTRG1, AP9101CAK-ADTRG1, AP9101CAK-AETRG1, and AP9101CAK-AFTRG1 are active Diodes Incorporated parts with identical electrical protection specifications. These require SOT-25 package accommodation but maintain the same fault protection (over-current, over-voltage) and operating temperature range. All are ROHS3 compliant and carry "Active" product status.
For Enhanced Protection with Package Change:
AP9214LA-AB-HSBR-7 (Diodes Incorporated, 6-UDFN) and BQ29729DSER (Texas Instruments, 6-WSON) provide single-cell lithium ion/polymer protection with additional short-circuit protection. Both are active products with ROHS3 compliance. These require PCB layout redesign but deliver enhanced fault protection coverage.
Frequently Asked Questions (FAQ)
Q: Can S-8241ADVMC-GDVT2G be replaced with S-8241ABPMC-GBPT2G without PCB modifications?
A: Yes. Both parts share identical SOT-23-5 packaging, pin configuration, and electrical specifications for single-cell lithium ion/polymer battery protection. Direct substitution is possible without layout changes.
Q: What is the difference between SOT-23-5 and SOT-25 packages?
A: SOT-23-5 and SOT-25 are both five-pin surface mount packages with SC-74A case designation. The primary difference lies in lead pitch and footprint dimensions. Substitution requires PCB footprint verification and potential layout adjustment.
Q: Why do some substitute parts include short-circuit protection when the original does not?
A: AP9214LA-AB-HSBR-7 and BQ29729DSER provide enhanced protection features beyond the original specification. Short-circuit protection is an additional fault detection capability. These parts remain functionally compatible for single-cell lithium ion/polymer applications but require evaluation of whether the additional protection is beneficial or unnecessary for the specific application.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the original S-8241ADVMC-GDVT2G specification.
Q: Which substitute part has the highest inventory availability?
A: S-8241ABPMC-GBPT2G offers 23,400 pcs in stock, the highest availability among all listed alternatives.
Q: Can I use an active product substitute for a "Not For New Designs" part?
A: Yes. Active product substitutes such as the AP9101 series (Diodes Incorporated) are suitable for ongoing production and field replacement applications. Active status indicates continued manufacturer support and availability.
