S-812C37AMC-C2RT2G Equivalent & Substitute Parts

Part Overview

The S-812C37AMC-C2RT2G is a linear voltage regulator IC from ABLIC Inc. designed for power management applications. This device delivers a fixed 3.7V output at 50mA in a compact SOT-23-5 surface mount package. The part is classified as Not For New Designs, indicating it has been superseded in ABLIC's product roadmap. Finding equivalent or substitute parts is necessary for applications requiring continued supply, design flexibility, or alternative packaging configurations while maintaining identical electrical performance.

Substitute Part Grouping Explanation

Substitution for the S-812C37AMC-C2RT2G is determined by strict equivalence across the following critical parameters:

• Output voltage specification: 3.7V fixed
• Output current capability: 50mA
• Input voltage rating: 16V maximum
• Voltage dropout characteristics: 0.35V @ 10mA
• Quiescent current: 500 nA
• Package configuration: SOT-23-5
• Operating temperature range: -40°C to 85°C
• Compliance certifications: ROHS3, REACH Unaffected

The identified substitute maintains all electrical specifications and package requirements. The primary distinction lies in packaging format (Tape & Reel versus Cut Tape) and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The S-812C37AMC-C2RT2U serves as a direct parametric equivalent to the S-812C37AMC-C2RT2G. Both parts are manufactured by ABLIC Inc. and share identical electrical specifications, thermal characteristics, and compliance certifications.

The primary distinction is product lifecycle status: the main part is designated Not For New Designs, while the substitute is Active. This status difference reflects ABLIC's current support and availability commitment. The substitute part also offers improved inventory availability (767 units in stock versus 4850 units for the main part in the specified packaging format).

Packaging format differs between the two parts: the main part is supplied in Tape & Reel configuration, while the substitute is supplied in Cut Tape format. This distinction affects procurement and assembly processes but does not impact electrical performance or PCB-level compatibility.

Selection between these parts should be based on procurement requirements, packaging preferences, and supply chain considerations rather than technical performance criteria.

Frequently Asked Questions (FAQ)

Q: Are the S-812C37AMC-C2RT2G and S-812C37AMC-C2RT2U electrically interchangeable?

A: Yes. Both parts deliver identical electrical performance across all specified parameters, including output voltage, current capacity, dropout voltage, quiescent current, and operating temperature range. They are pin-compatible and functionally equivalent at the circuit level.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape packaging provides components on tape segments cut to specific lengths, typically used for lower-volume orders or manual assembly. Both formats contain identical components; the difference is in delivery and handling format.

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

A: This designation indicates that ABLIC has transitioned this part to end-of-life status and recommends using alternative parts for new product development. However, the part remains available for existing applications and designs already in production.

Q: Can I use the S-812C37AMC-C2RT2U as a direct replacement in existing designs?

A: Yes. The substitute part maintains full electrical and mechanical compatibility. No circuit modifications or PCB redesign is required. The only consideration is packaging format, which affects procurement and assembly processes but not circuit functionality.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the S-812C37AMC-C2RT2G and S-812C37AMC-C2RT2U are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
