Key Parameters

Substitute Part Grouping Explanation

Substitution for the CY2305CSXA-1HT is determined by strict equivalence across the following critical parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) — identical physical footprint required for PCB compatibility
• Frequency - Max: 133.33MHz — maximum operating frequency specification
• Ratio - Input:Output: 1:5 — signal distribution configuration
• Voltage - Supply: 3V ~ 3.6V — power supply range
• Input Type: LVCMOS, LVTTL — input signal compatibility
• Output Type: LVCMOS — output signal standard
• Operating Temperature: -40°C ~ 85°C — thermal operating range
• PLL: Yes — phase-locked loop functionality
• RoHS Status: ROHS3 Compliant — environmental compliance requirement
• Moisture Sensitivity Level (MSL): 3 (168 Hours) — handling and storage requirements

All identified substitute parts match these parameters exactly. The primary distinction among substitutes is product status and packaging format (Tape & Reel vs. other configurations).

Parameter Comparison

Engineering Selection Recommendations

CY2305CSXI-1HT is the primary substitute for CY2305CSXA-1HT. This part maintains Active product status with Infineon Technologies and carries identical electrical and mechanical specifications. The part number suffix indicates Tape & Reel packaging format, which is standard for production environments.

CY2305CSXI-1T is an alternative substitute with Active product status. This variant also maintains full parametric equivalence and is available in Tape & Reel packaging. Inventory availability is lower than CY2305CSXI-1HT.

CY23S05SXI-1T is a substitute part from the Spread Aware™ series, maintaining Active product status and full parametric equivalence. This variant is suitable for applications requiring spread spectrum clock generation capabilities. Inventory availability is limited.

All substitute parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements. Selection among substitutes should be based on availability, packaging requirements, and application-specific needs for spread spectrum functionality.

Frequently Asked Questions (FAQ)

Q: Can CY2305CSXI-1HT be used as a direct replacement for CY2305CSXA-1HT?

A: Yes. CY2305CSXI-1HT is a parametric equivalent with identical electrical specifications, frequency rating, input/output ratios, supply voltage range, operating temperature range, and package configuration. The primary difference is product status (Active vs. Obsolete) and packaging format.

Q: What is the difference between CY2305CSXI-1HT and CY2305CSXI-1T?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The difference lies in packaging format designation. Both are available in Tape & Reel format and maintain Active product status.

Q: Why is CY23S05SXI-1T listed as a substitute if it has a different base product number?

A: CY23S05SXI-1T maintains all critical electrical and mechanical parameters required for substitution: identical package, frequency, input/output ratio, supply voltage, signal types, operating temperature, and compliance certifications. The base product number difference reflects the Spread Aware™ series designation, which provides additional spread spectrum functionality without affecting core fanout buffer operation.

Q: Are all substitute parts available in the same packaging format?

A: CY2305CSXA-1HT does not specify a packaging format in the provided data. All identified substitutes are available in Tape & Reel (TR) format. Packaging format compatibility should be confirmed against specific procurement requirements.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts are ROHS3 Compliant and REACH Unaffected. Moisture Sensitivity Level is 3 (168 Hours) for all parts, requiring controlled storage and handling conditions.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All substitute parts share identical 8-SOIC (0.154", 3.90mm Width) package specifications, enabling direct PCB footprint compatibility without layout modifications.
