Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CY2309CZXC-1HT are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Critical Parameters for Substitution:

• Package / Case: 16-TSSOP (0.173", 4.40mm Width)
• Input Type: LVCMOS, LVTTL
• Output Type: LVCMOS
• Voltage - Supply: 3V ~ 3.6V
• Operating Temperature: 0°C ~ 70°C
• PLL: Yes with Bypass
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 3 (168 Hours)

Frequency and Ratio Considerations: The CY2309CZXC-1HT operates at a maximum frequency of 133.33MHz with a 1:9 input-to-output ratio. Substitute parts must maintain these specifications or provide equivalent performance within the same operational envelope. Parts with different ratios or frequencies may be considered only if they meet all other electrical and mechanical requirements and do not compromise system functionality.

Parameter Comparison

Engineering Selection Recommendations

CY2309ZXC-1HT is the primary substitute for CY2309CZXC-1HT. Both parts maintain identical electrical specifications including the 1:9 input-to-output ratio, 133.33MHz maximum frequency, and all voltage, temperature, and signal integrity parameters. The CY2309ZXC-1HT is currently in Active product status, ensuring long-term availability and supply chain continuity. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements. The primary difference is packaging format: CY2309ZXC-1HT is supplied in Tape & Reel (TR) format, which is standard for production environments.

CY2308ZXC-1HT is an alternative substitute with the same electrical and mechanical characteristics as the main part, with the exception of the input-to-output ratio, which is 1:8 instead of 1:9. This part is also in Active product status and meets all compliance and regulatory requirements. Selection of CY2308ZXC-1HT requires confirmation that the 1:8 ratio is functionally compatible with the target application.

Both substitute parts are manufactured by Infineon Technologies and share the same 16-TSSOP package, supply voltage range, operating temperature range, and signal interface specifications as the CY2309CZXC-1HT.

Frequently Asked Questions (FAQ)

Q: Can CY2309ZXC-1HT directly replace CY2309CZXC-1HT?

A: Yes. Both parts are electrically and mechanically equivalent. The CY2309ZXC-1HT maintains the same 1:9 input-to-output ratio, 133.33MHz maximum frequency, 3V to 3.6V supply voltage, 16-TSSOP package, and all signal interface specifications. The primary difference is packaging format: CY2309ZXC-1HT is supplied in Tape & Reel (TR) format for production use, while CY2309CZXC-1HT was supplied in bulk format. Both are ROHS3 Compliant and REACH Unaffected.

Q: What is the difference between CY2308ZXC-1HT and CY2309ZXC-1HT?

A: The primary difference is the input-to-output ratio. CY2308ZXC-1HT provides a 1:8 ratio, while CY2309ZXC-1HT provides a 1:9 ratio. All other electrical and mechanical parameters are identical, including frequency, voltage, temperature range, package type, and compliance certifications. Selection between these parts depends on the specific output channel requirements of the target application.

Q: Are the substitute parts available in the same package as the main part?

A: Yes. All three parts use the 16-TSSOP (0.173", 4.40mm Width) package. This ensures mechanical compatibility with existing PCB layouts and assembly processes. The substitute parts differ only in packaging format (Tape & Reel vs. bulk) and product status (Active vs. Obsolete).

Q: What is the significance of the product status difference?

A: The CY2309CZXC-1HT is listed as Obsolete, indicating it is no longer in active production. The substitute parts CY2308ZXC-1HT and CY2309ZXC-1HT are both in Active status, ensuring continued availability, technical support, and supply chain reliability for new designs and ongoing production requirements.

Q: Do the substitute parts meet the same compliance and regulatory requirements?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and carry the same Moisture Sensitivity Level (MSL) rating of 3 (168 Hours). They meet identical environmental and regulatory standards for industrial and commercial applications.
