Substitute Part Grouping Explanation

Substitution of the S-817B32AMC-CWVT2G is determined by strict equivalence across the following critical parameters:

• Output voltage specification: 3.2V fixed
• Maximum output current: 50mA
• Maximum input voltage: 10V
• Voltage dropout characteristics: 0.41V @ 10mA
• Package type: SOT-23-5 (SC-74A, SOT-753)
• Operating temperature range: -40°C ~ 85°C
• Quiescent current: 2.5 µA
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The S-817B32AMC-CWVT2U qualifies as a parametric equivalent based on identical electrical specifications and package configuration. The primary distinction is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) format. Both parts maintain identical functional and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The S-817B32AMC-CWVT2U is a direct parametric equivalent suitable for applications currently using the S-817B32AMC-CWVT2G. Both parts are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements. The S-817B32AMC-CWVT2U carries Active product status, providing assurance of continued availability and manufacturing support, whereas the main part is designated Not For New Designs. For production continuity and long-term supply chain stability, the S-817B32AMC-CWVT2U is the preferred selection. Packaging format differences (Tape & Reel versus Cut Tape) do not affect electrical performance or functional compatibility; selection between formats depends on assembly process requirements and volume considerations.

Frequently Asked Questions (FAQ)

Q: Can the S-817B32AMC-CWVT2U directly replace the S-817B32AMC-CWVT2G in existing designs?

A: Yes. Both parts are parametrically identical across all electrical specifications, output voltage, current ratings, temperature range, and package configuration. Direct substitution is supported without circuit modification.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) packaging provides components on cut segments of carrier tape, typically used for lower volumes or manual assembly processes. Electrical and functional performance is identical between formats.

Q: Why is the main part marked "Not For New Designs"?

A: This designation indicates the part is in mature or end-of-life status. ABLIC Inc. recommends using the S-817B32AMC-CWVT2U (Active status) for new design implementations to ensure long-term supply availability and manufacturing continuity.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance and REACH unaffected status. Regulatory and environmental certifications are equivalent.

Q: What inventory considerations apply to these parts?

A: The S-817B32AMC-CWVT2G has 1031 pieces in stock; the S-817B32AMC-CWVT2U has 1065 pieces in stock. Both are available as new original components. Inventory levels may vary based on current demand and supply conditions.
