Substitute Part Grouping Explanation

Substitution of the CY2308SC-2 is determined by strict equivalence across the following critical parameters:

Functional Type: Fanout Buffer (Distribution) with Zero Delay Buffer capability
Frequency Rating: Maximum 133.3MHz operation
Input/Output Ratio: 1:8 configuration
PLL Presence: Integrated Phase-Locked Loop required
Signal Levels: LVCMOS/LVTTL input compatibility with LVCMOS output
Supply Voltage: 3V to 3.6V operating range
Package: 16-SOIC (0.154", 3.90mm Width) surface mount form factor
Pin Compatibility: Identical pinout and electrical interface

The CY2308SXC-2 meets all these criteria and is classified as a parametric equivalent. The primary distinction between the main part and its substitute is product status and packaging format, not electrical or mechanical performance.

Engineering Selection Recommendations

The CY2308SXC-2 is the direct parametric equivalent for the obsolete CY2308SC-2. Both parts share identical electrical specifications, frequency ratings, signal interface characteristics, and physical packaging.

The CY2308SXC-2 offers two significant advantages:

Product Status: The CY2308SXC-2 is classified as Active, ensuring ongoing availability and manufacturer support, whereas the CY2308SC-2 is Obsolete.
Regulatory Compliance: The CY2308SXC-2 is ROHS3 Compliant, meeting current environmental and hazardous substance restrictions. The CY2308SC-2 is RoHS non-compliant and may not satisfy procurement or regulatory requirements for new designs or production runs.

For applications requiring the CY2308SC-2, the CY2308SXC-2 provides full electrical and mechanical compatibility with improved compliance status and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Are the CY2308SC-2 and CY2308SXC-2 pin-compatible?
