Substitute Part Grouping Explanation

Substitution eligibility for the S-816A40AMC-BAPT2G is determined by strict equivalence across the following critical parameters:

• Manufacturer: ABLIC Inc. (same manufacturer ensures design compatibility)
• Series: S-816 (same product family)
• Type: External Transistor Linear Regulator Controller (identical functional architecture)
• Number of Outputs: 1 (single output configuration)
• Voltage - Input: 16V (identical input voltage specification)
• Current - Supply: 40µA (identical quiescent current)
• Operating Temperature Range: -40°C ~ 85°C (identical thermal operating window)
• Mounting Type: Surface Mount (identical assembly method)
• Package / Case: SC-74A, SOT-753 (identical physical footprint)
• Supplier Device Package: SOT-23-5 (identical pin configuration)
• RoHS Status: ROHS3 Compliant (identical environmental compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (identical moisture handling)

Parts meeting all these criteria are considered parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The S-816A40AMC-BAPT2U is a direct parametric equivalent to the S-816A40AMC-BAPT2G across all specified electrical, mechanical, and environmental parameters. The primary distinction is product lifecycle status: the main part is designated "Not For New Designs," while the substitute carries "Active" status, indicating ongoing manufacturer support and availability.

Both parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity classification, ensuring regulatory and environmental compatibility. The substitute part demonstrates superior inventory availability (2331 units versus 1050 units), supporting supply chain continuity.

For applications currently utilizing the S-816A40AMC-BAPT2G, the S-816A40AMC-BAPT2U provides direct functional and physical interchangeability without circuit modification or re-qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can the S-816A40AMC-BAPT2U replace the S-816A40AMC-BAPT2G in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, pin configurations, and package dimensions. Direct substitution is possible without circuit redesign.

Q: Are there differences in compliance certifications between these parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1 - Unlimited). Regulatory and environmental requirements are equivalent.

Q: What is the significance of the "Not For New Designs" status on the main part?

A: This designation indicates the S-816A40AMC-BAPT2G has reached end-of-life or is being phased out by the manufacturer. The S-816A40AMC-BAPT2U, carrying "Active" status, represents the current production equivalent with ongoing manufacturer support.

Q: Are the package and pin configurations identical?

A: Yes. Both parts use SOT-23-5 supplier device packaging with SC-74A and SOT-753 case designations. Physical footprint and pin layout are identical, enabling direct PCB compatibility.

Q: Is inventory availability a factor in substitution decisions?

A: Inventory levels reflect current stock status and may influence procurement timelines. The substitute part shows higher availability (2331 units), which may support faster fulfillment for production requirements.
