SSC3S902 Equivalent & Substitute Parts

Part Overview

The SSC3S902 is an AC/DC converter integrated circuit manufactured by Sanken Electric USA Inc., classified as a Power Management (PMIC) component. This offline half-bridge topology controller operates across a switching frequency range of 32kHz to 300kHz and is designed for isolated power conversion applications. The device is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to address packaging availability, inventory requirements, and application-specific distribution channels while maintaining full electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSC3S902 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part SSC3S901 shares identical specifications with the main part across all functional and environmental criteria, including topology, voltage ratings, switching frequency range, fault protection mechanisms, package configuration, and compliance certifications. The primary distinction between these parts is packaging format: SSC3S902 is supplied in Tape & Reel (TR) format, while SSC3S901 is available in Cut Tape (CT) and Digi-Reel® format. Both parts belong to the SSC3S900 series and maintain full parametric equivalence, enabling direct substitution in applications where packaging format does not impose supply chain or assembly constraints.

Key Parameters Determining Substitution:

• Topology: Half-Bridge
• Voltage - Breakdown: 600V
• Voltage - Supply (Vcc/Vdd): 9.8V ~ 35V
• Frequency - Switching: 32kHz ~ 300kHz
• Package / Case: 18-SOIC (0.213", 5.40mm Width)
• Fault Protection: Current Limiting, Over Load, Over Temperature, Over Voltage, UVLO
• Control Features: Soft Start
• Operating Temperature: -40°C ~ 85°C (TA)

Parameter Comparison

Engineering Selection Recommendations

Both SSC3S902 and SSC3S901 are active production components manufactured by Sanken Electric USA Inc. and carry ROHS3 compliance certification. Selection between these parts should be based on packaging format requirements and supply chain logistics rather than electrical performance, as all functional parameters are identical.

SSC3S902 (Tape & Reel format) is appropriate for high-volume automated assembly operations where continuous reel feeding is standard practice.

SSC3S901 (Cut Tape & Digi-Reel® format) is appropriate for lower-volume applications, mixed-component orders, or supply chains where alternative packaging formats provide distribution advantages.

Both parts maintain identical electrical specifications, thermal performance, fault protection mechanisms, and compliance certifications. The choice between them does not affect circuit performance, reliability, or regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can SSC3S901 be used as a direct replacement for SSC3S902 in existing designs?

A: Yes. SSC3S901 is a parametric equivalent with identical electrical specifications, package configuration, and performance characteristics. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Direct substitution is valid from an engineering standpoint.

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

A: Tape & Reel (TR) format supplies components on continuous reels suitable for automated pick-and-place assembly. Cut Tape (CT) format supplies components on tape segments, typically used for lower-volume orders or mixed-component shipments. Digi-Reel® is an alternative reel format. All three formats contain the same component in the same package.

Q: Are there any electrical performance differences between SSC3S902 and SSC3S901?

A: No. Both parts share identical electrical specifications including voltage ratings, switching frequency range, fault protection features, control characteristics, and operating temperature range. Performance in circuit is equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSC3S902 and SSC3S901 are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity). Both carry the same ECCN and HTSUS classifications.

Q: Which part should be selected for new design?

A: Selection should be based on supply chain and assembly requirements. For high-volume automated assembly, Tape & Reel format (SSC3S902) is standard. For lower volumes or mixed orders, Cut Tape or Digi-Reel® format (SSC3S901) may provide logistical advantages. Electrical performance is identical.

Q: Are both parts currently in production?

A: Yes. Both SSC3S902 and SSC3S901 are active production components with current inventory availability.
