S-82A1AAP-I6T1U Equivalent & Substitute Parts

Part Overview

The S-82A1AAP-I6T1U is a lithium-ion battery protection integrated circuit manufactured by ABLIC Inc. This PMIC (Power Management IC) is designed for single-cell lithium-ion and lithium-polymer battery applications with over-current fault protection. The device is housed in a 6-SMD flat-lead package (SNT-6A) and operates across the temperature range of -40°C to 85°C. The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same functional category, packaging specification, and environmental operating conditions. Alternative models within the S-82A1A and S-8240A series provide direct functional equivalence for applications requiring component interchangeability.

Frequently Asked Questions (FAQ)

Q: Can S-8240 series parts directly replace S-82A1A series parts in existing designs?

A: Yes. Both series maintain identical electrical specifications, operating temperature ranges, fault protection characteristics, and physical packaging (6-SMD, Flat Leads, SNT-6A). The parts are mechanically and functionally interchangeable for single-cell lithium-ion battery protection applications.

Q: What is the significance of the SNT-6A package designation?

A: SNT-6A specifies the supplier device package format: a 6-lead surface-mount package with flat leads. All substitute parts use this identical package specification, ensuring PCB footprint compatibility and assembly process equivalence.

Q: Are there any differences in moisture sensitivity between substitute parts?

A: No. All substitute parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity constraints. Parts may be stored and handled without desiccant protection or time-limited exposure windows.

Q: Does the operating temperature range vary among substitute parts?

A: No. All substitute parts operate across the identical temperature range of -40°C to 85°C (TA). No thermal performance differentiation exists between the primary part and any listed substitute.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts maintain ROHS3 compliance and REACH unaffected status. These regulatory designations are uniform across the entire substitute parts list, ensuring equivalent compliance posture for regulated applications.

Q: Are there inventory considerations when selecting among substitute parts?

A: Yes. Inventory levels vary significantly across the substitute parts list. S-8240AAZ-I6T1U provides the highest availability at 10,002 pieces. S-82A1AAC-I6T1U offers substantial inventory at 5,957 pieces. Selection may be influenced by supply chain requirements and lead-time considerations.

Q: Can parts from different base product families (S-82A1 vs. S-8240) be mixed in the same production run?

A: Yes. Both base product families maintain identical electrical performance, packaging specifications, and environmental operating parameters. Cross-family substitution does not introduce functional or compatibility constraints.

Q: What is the significance of the Tape & Reel packaging format?

A: Tape & Reel (TR) packaging indicates the parts are supplied on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly processes. All substitute parts use this identical packaging format, ensuring assembly equipment compatibility.
