SSC3S901 Equivalent & Substitute Parts

Part Overview

The SSC3S901 is an AC/DC converter controller integrated circuit manufactured by Sanken Electric USA Inc., designed for offline half-bridge topology power management applications. This Power Management (PMIC) device operates across a switching frequency range of 32kHz to 300kHz and is housed in an 18-SOIC surface mount package. The SSC3S901 is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Alternative part numbers within the SSC3S900 series are available to accommodate different packaging and inventory requirements while maintaining identical electrical and functional specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the SSC3S900 series is determined by electrical and mechanical parameter equivalence. The SSC3S901 and SSC3S902 are parametrically equivalent AC/DC converter controller ICs with identical electrical specifications across all critical parameters: breakdown voltage (600V), supply voltage range (9.8V ~ 35V), switching frequency range (32kHz ~ 300kHz), fault protection features, control characteristics, operating temperature range, and package form factor (18-SOIC).

The primary distinction between substitute parts is packaging configuration. The SSC3S901 is supplied in Cut Tape (CT) and Digi-Reel® packaging, while the SSC3S902 is supplied in Tape & Reel (TR) packaging. Both variants maintain identical electrical performance and are housed in the same 18-SOP supplier device package. Selection between these substitutes is based solely on packaging and inventory availability requirements, not on functional or electrical differences.

Parameter Comparison

Engineering Selection Recommendations

Both SSC3S901 and SSC3S902 are active products with full ROHS3 compliance and identical electrical specifications. Selection between these parts is determined by packaging requirements and supply chain considerations.

The SSC3S901, supplied in Cut Tape and Digi-Reel® packaging with 20,300 pieces in stock, is suitable for applications requiring flexible packaging options or lower volume procurement. The SSC3S902, supplied in Tape & Reel format with 1,036 pieces in stock, is appropriate for high-volume automated assembly processes that utilize standard reel-based component handling systems.

Both parts are classified under ECCN EAR99 and HTSUS 8542.39.0001, indicating identical regulatory and trade classification status. The choice between SSC3S901 and SSC3S902 does not affect electrical performance, thermal characteristics, or functional behavior in the target application. PCB layout, thermal management, and circuit design considerations remain identical regardless of which part number is selected.

Frequently Asked Questions (FAQ)

Q: Are SSC3S901 and SSC3S902 electrically interchangeable?

A: Yes. Both parts are parametrically equivalent AC/DC converter controller ICs with identical electrical specifications, including breakdown voltage, supply voltage range, switching frequency, fault protection, and operating temperature range. They perform identically in circuit applications.

Q: What is the difference between SSC3S901 and SSC3S902?

A: The primary difference is packaging format. The SSC3S901 is supplied in Cut Tape (CT) and Digi-Reel® packaging, while the SSC3S902 is supplied in Tape & Reel (TR) packaging. Both use the same 18-SOP supplier device package and 18-SOIC case form factor.

Q: Can I substitute SSC3S902 for SSC3S901 on an existing PCB design?

A: Yes. Both parts use identical 18-SOIC surface mount packages with the same pin configuration, pitch, and mechanical dimensions (0.213" width, 5.40mm). No PCB layout modifications are required.

Q: Which part should I select for high-volume production?

A: The SSC3S902 in Tape & Reel packaging is optimized for high-volume automated assembly processes. Standard reel-based component handling systems are designed for TR packaging formats.

Q: Which part should I select for prototyping or low-volume applications?

A: The SSC3S901 in Cut Tape and Digi-Reel® packaging provides flexibility for prototyping, small-batch production, and applications with variable volume requirements.

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

A: No. Both SSC3S901 and SSC3S902 carry identical RoHS3 compliance status, ECCN classification (EAR99), and HTSUS code (8542.39.0001). Regulatory and environmental compliance is equivalent.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I mix SSC3S901 and SSC3S902 parts in the same production run?

A: Yes. Since both parts are electrically and functionally identical, they can be used interchangeably within the same design and production environment. Packaging format differences do not affect circuit performance or reliability.
