Key Parameters

Substitute Part Grouping Explanation

Substitution of the CY2308SC-3 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Maximum frequency: 133.3MHz
• Input-to-output ratio: 1:8
• Input signal types: LVCMOS, LVTTL
• Output signal type: LVCMOS
• Supply voltage range: 3V ~ 3.6V
• Operating temperature range: 0°C ~ 70°C
• PLL functionality: Present
• Multiplier capability: Yes

Mechanical Compatibility Parameters:

• Package type: 16-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Number of circuits: 1

Regulatory & Compliance Parameters:

• Moisture Sensitivity Level: 3 (168 Hours)
• ECCN classification: EAR99
• HTSUS code: 8542.39.0001

The CY2308SXC-4 meets all electrical and mechanical equivalence criteria and is therefore classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The CY2308SXC-4 is a direct parametric equivalent to the CY2308SC-3 across all electrical and mechanical specifications. Both devices share identical functional characteristics, signal compatibility, frequency performance, and package form factor.

Product Status Consideration: The CY2308SC-3 is classified as Obsolete, while the CY2308SXC-4 is classified as Last Time Buy. This status difference indicates that the CY2308SXC-4 remains available for procurement but with limited future availability.

Compliance Difference: The CY2308SXC-4 is ROHS3 Compliant, whereas the CY2308SC-3 is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulatory requirements.

Packaging: The CY2308SXC-4 is supplied in Tube packaging, which may differ from the original part's packaging configuration.

For applications requiring RoHS compliance or where component availability is a concern, the CY2308SXC-4 is the appropriate selection. For legacy systems where RoHS compliance is not mandated, both parts are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Are the CY2308SC-3 and CY2308SXC-4 pin-compatible?

A: Yes. Both devices use the 16-SOIC (0.154", 3.90mm Width) package with identical pin configurations. They are direct pin-for-pin replacements.

Q: Can the CY2308SXC-4 operate at the same frequency as the CY2308SC-3?

A: Yes. Both parts support a maximum frequency of 133.3MHz with identical 1:8 input-to-output ratio and PLL functionality.

Q: What is the difference in RoHS compliance between these parts?

A: The CY2308SC-3 is RoHS non-compliant, while the CY2308SXC-4 is ROHS3 Compliant. Applications subject to RoHS regulations must use the CY2308SXC-4.

Q: Are the supply voltage requirements identical?

A: Yes. Both parts operate within the 3V ~ 3.6V supply voltage range and share identical operating temperature specifications of 0°C ~ 70°C.

Q: What does "Last Time Buy" status mean for the CY2308SXC-4?

A: Last Time Buy indicates that the manufacturer has announced end-of-life for this part. Existing inventory is available for purchase, but no future production is planned. Procurement should account for this limited availability window.

Q: Are there any signal integrity differences between these substitutes?

A: No. Both parts support identical input types (LVCMOS, LVTTL) and output type (LVCMOS), with equivalent MSL ratings of 3 (168 Hours).
