SCANPSC110FSC Equivalent & Substitute Parts

Part Overview

The SCANPSC110FSC is a specialized interface IC manufactured by onsemi, packaged in 28-SOIC form factor with IEEE 1149.1 compliance. This component operates within the 4.5V to 5.5V supply voltage range and is classified as an obsolete product. Due to its obsolete status, identifying functionally equivalent substitute components is essential for system redesign, legacy system maintenance, and continued product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCANPSC110FSC is determined by the following critical parameters:

• Interface Standard: IEEE 1149.1 compliance is mandatory for functional equivalence
• Voltage Supply Range: 4.5V ~ 5.5V operating range must be maintained
• Category: Specialized interface IC functionality
• Surface Mount Compatibility: Required for PCB integration

The identified substitute CA91C142D-33CE meets the core electrical requirements (IEEE 1149.1 interface, 4.5V ~ 5.5V supply voltage) and maintains surface mount compatibility. However, packaging differs significantly: the substitute uses 313-PBGA form factor versus the original 28-SOIC, requiring PCB layout redesign.

Engineering Selection Recommendations

SCANPSC110FSC (Original Component)

• Product Status: Obsolete
• Suitable for: Legacy system maintenance where existing inventory is available
• Limitation: No new production; long-term sourcing unavailable

CA91C142D-33CE (Substitute)

• Product Status: Active
• Electrical Compatibility: Meets IEEE 1149.1 and 4.5V ~ 5.5V requirements
• Design Consideration: Package change from 28-SOIC to 313-PBGA requires PCB redesign
• Compliance: REACH Unaffected status maintained
• Availability: Active production status ensures continued supply

Selection between these components depends on design flexibility. If PCB layout modification is feasible, CA91C142D-33CE provides an active, supported alternative. If package footprint must remain unchanged, alternative 28-SOIC interface components meeting IEEE 1149.1 specification should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can CA91C142D-33CE be used as a direct drop-in replacement for SCANPSC110FSC? A: No. While both components meet the IEEE 1149.1 interface standard and 4.5V ~ 5.5V supply voltage requirements, the package change from 28-SOIC to 313-PBGA (35x35) requires PCB layout redesign. Direct socket substitution is not possible.

Q: What are the key compatibility criteria for substituting SCANPSC110FSC? A: Substitute components must satisfy: IEEE 1149.1 interface compliance, 4.5V ~ 5.5V supply voltage range, surface mount capability, and functional equivalence as a specialized interface IC. Package form factor is secondary to electrical compatibility but impacts PCB integration.

Q: Why is the SCANPSC110FSC obsolete? A: The component is classified as obsolete by the manufacturer, indicating end-of-life status and discontinued production. New designs should transition to active alternatives such as CA91C142D-33CE.

Q: What is the impact of MSL rating difference between the two components? A: SCANPSC110FSC has MSL 1 (unlimited moisture exposure tolerance), while CA91C142D-33CE has MSL 3 (168-hour limit). This affects storage and handling procedures; CA91C142D-33CE requires more controlled moisture conditions during storage and assembly.

Q: Are both components REACH compliant? A: Both components carry REACH Unaffected status, indicating compliance with REACH regulations. No additional regulatory barriers exist for substitution from this perspective.
