S-816A42AMC-BART2G Equivalent & Substitute Parts

Part Overview

The S-816A42AMC-BART2G is a linear regulator controller IC manufactured by ABLIC Inc., designed for external transistor applications with a single output configuration. This device operates at 4.2V output with 1A current capability in a compact SOT-23-5 surface mount package.

The main part carries a "Not For New Designs" product status, which necessitates identification of active equivalent alternatives for ongoing production and new design implementations. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S-816A42AMC-BART2G is determined by strict equivalence across the following critical parameters:

• Output voltage specification (4.2V)
• Output current rating (1A)
• Supply current consumption (40µA)
• Input voltage maximum rating (16V)
• Operating temperature range (-40°C to 85°C)
• Package configuration (SOT-23-5)
• Regulator architecture (External Transistor, Single Output)
• Mounting technology (Surface Mount)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The S-816A42AMC-BART2U satisfies all substitution requirements and is the identified equivalent for this product line.

Parameter Comparison

Engineering Selection Recommendations

The S-816A42AMC-BART2U is the direct parametric equivalent for applications currently using the S-816A42AMC-BART2G. Both parts maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product lifecycle status: the S-816A42AMC-BART2G carries "Not For New Designs" designation, while the S-816A42AMC-BART2U maintains "Active" status. This distinction is significant for long-term supply chain planning and new product development initiatives.

Both parts satisfy identical compliance requirements: ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Moisture sensitivity level (MSL 1) indicates unlimited shelf life under standard storage conditions.

For applications requiring the S-816A42AMC-BART2G, direct substitution with the S-816A42AMC-BART2U is supported without circuit modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the S-816A42AMC-BART2U directly replace the S-816A42AMC-BART2G in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage (4.2V), current ratings (1A output, 40µA supply), temperature range (-40°C to 85°C), and SOT-23-5 package configuration. Direct substitution is supported without circuit modification.

Q: What is the significance of the "Not For New Designs" status on the S-816A42AMC-BART2G?

A: This designation indicates the part is in mature or end-of-life phase and should not be selected for new product development. The S-816A42AMC-BART2U, with "Active" status, is the recommended choice for new designs requiring this functionality.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use identical SOT-23-5 packaging (SC-74A, SOT-753 case designations) with identical pinout and mounting requirements. PCB layout and footprints are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, classified as EAR99 for export purposes, and carry MSL 1 moisture sensitivity rating. Compliance profiles are identical.

Q: What is the supply current specification, and why is it relevant?

A: Both parts consume 40µA supply current. This specification is critical for battery-powered or low-power applications where quiescent current directly impacts system power consumption and battery life.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts operate across the identical temperature range of -40°C to 85°C (TA). Applications within this range require no thermal re-qualification when substituting between these parts.
