LV51130T-TLM-E Equivalent & Substitute Parts

Part Overview

The LV51130T-TLM-E is a Battery Protection IC for Lithium Ion 2-cell applications manufactured by onsemi in an 8-MSOP package. This component provides over-current and short-circuit fault protection for battery management systems. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LV51130T-TLM-E is determined by the following critical parameters:

Core Functional Requirements:

• Battery Protection IC function
• Lithium Ion battery chemistry support
• 2-cell configuration capability
• Over-current fault protection (mandatory)
• Short-circuit fault protection (mandatory)

Environmental & Compliance Requirements:

• Operating temperature range compatibility
• RoHS3 compliance
• Surface mount technology
• REACH compliance status

Mechanical Compatibility:

• Package form factor and pin count
• Supplier device package specification

The S-8252AAL-M6T1U from ABLIC Inc. qualifies as a substitute based on matching core functional requirements (battery protection, Lithium Ion chemistry, 2-cell support, over-current protection) and compliance certifications (ROHS3, REACH Unaffected). Package differences (SOT-23-6 vs. 8-MSOP) require PCB layout redesign but do not affect electrical functionality.

Parameter Comparison

Engineering Selection Recommendations

The S-8252AAL-M6T1U is an active product with current manufacturing availability (94,820 pcs in stock), providing supply chain continuity for the obsolete LV51130T-TLM-E. Both components meet ROHS3 and REACH compliance requirements.

Substitution Considerations:

The S-8252AAL-M6T1U supports Lithium Ion/Polymer chemistry, extending compatibility beyond the LV51130T-TLM-E's Lithium Ion specification. The substitute provides over-current protection; however, the LV51130T-TLM-E includes both over-current and short-circuit protection. Applications requiring short-circuit protection must evaluate whether the S-8252AAL-M6T1U's over-current protection alone meets system safety requirements.

Operating temperature range of the S-8252AAL-M6T1U (-40°C ~ 85°C) exceeds the LV51130T-TLM-E (-30°C ~ 85°C), providing broader environmental coverage.

Package transition from 8-MSOP to SOT-23-6 requires PCB redesign and layout validation. Pin configuration and electrical interface compatibility must be verified against application schematics.

Frequently Asked Questions (FAQ)

Q: Can the S-8252AAL-M6T1U directly replace the LV51130T-TLM-E without PCB modification?

A: No. The S-8252AAL-M6T1U uses SOT-23-6 packaging versus the LV51130T-TLM-E's 8-MSOP package. PCB layout redesign is required. Pin-to-pin electrical compatibility must be verified against the application schematic.

Q: Does the S-8252AAL-M6T1U provide equivalent short-circuit protection?

A: The S-8252AAL-M6T1U provides over-current protection. The LV51130T-TLM-E provides both over-current and short-circuit protection. Applications dependent on short-circuit fault detection must evaluate whether over-current protection alone satisfies system requirements.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the LV51130T-TLM-E and S-8252AAL-M6T1U are ROHS3 compliant and REACH Unaffected.

Q: What is the operating temperature difference between these components?

A: The LV51130T-TLM-E operates from -30°C to 85°C. The S-8252AAL-M6T1U operates from -40°C to 85°C, providing 10°C additional low-temperature margin.

Q: Is the S-8252AAL-M6T1U suitable for Lithium Polymer batteries?

A: Yes. The S-8252AAL-M6T1U supports both Lithium Ion and Lithium Ion/Polymer chemistry, making it compatible with both battery types.

Q: What is the product status difference?

A: The LV51130T-TLM-E is obsolete with no ongoing manufacturing. The S-8252AAL-M6T1U is active with current production and 94,820 units in stock, ensuring supply availability.
