Key Parameters

Substitute Part Grouping Explanation

Substitution of the CY2305CSXC-1HT is determined by strict equivalence across the following critical parameters:

• Frequency capability (133.33MHz maximum)
• Input-to-output ratio (1:5)
• Supply voltage range (3V ~ 3.6V)
• Package type (8-SOIC with 0.154" width, 3.90mm)
• Input/output signal types (LVCMOS/LVTTL input, LVCMOS output)
• PLL functionality (required)
• Mounting type (Surface Mount)

The CY23S05SXC-1HT meets all these criteria and is classified as a parametric equivalent. The primary distinction between the main part and its substitute is the packaging format (Cut Tape vs. Tape & Reel) and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The CY23S05SXC-1HT is a direct parametric equivalent to the CY2305CSXC-1HT. Both devices are ROHS3 compliant and carry identical MSL ratings, ensuring compatibility in regulated and moisture-sensitive applications. The CY23S05SXC-1HT is currently in Active product status, providing extended availability compared to the Last Time Buy status of the CY2305CSXC-1HT. Selection between these parts should be based on packaging requirements: the CY2305CSXC-1HT is available in Cut Tape format, while the CY23S05SXC-1HT is supplied in Tape & Reel format. Both are suitable for surface mount assembly with identical thermal and electrical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the CY23S05SXC-1HT replace the CY2305CSXC-1HT in existing designs?

A: Yes. Both devices are parametrically equivalent across all critical electrical and mechanical specifications, including frequency, voltage supply, package dimensions, and signal types. The primary difference is packaging format and product lifecycle status.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging provides individual component strips cut to specified lengths, suitable for smaller volume orders. Tape & Reel (TR) packaging supplies components on continuous reels, optimized for high-volume automated assembly. Both formats contain identical components in the same 8-SOIC package.

Q: Are there any compliance differences between these parts?

A: No. Both the CY2305CSXC-1HT and CY23S05SXC-1HT carry identical ROHS3 compliance, REACH status, and MSL ratings. They are functionally equivalent for regulatory and environmental requirements.

Q: Why is the CY2305CSXC-1HT marked as Last Time Buy?

A: Last Time Buy status indicates that Infineon Technologies is discontinuing this specific part number. The CY23S05SXC-1HT, which is in Active status, represents the recommended path forward for new designs and ongoing procurement.

Q: Do these parts require different PCB layouts or assembly procedures?

A: No. Both devices use the identical 8-SOIC package with matching pin configurations and dimensions. PCB layouts and assembly procedures are interchangeable.
