CY2545QC010 Equivalent & Substitute Parts

Part Overview

The CY2545QC010 is a Fanout Distribution, Fractional N Synthesizer, Multiplexer, and Spread Spectrum Clock Generator IC manufactured by Infineon Technologies. This device operates at a maximum frequency of 166MHz and integrates a Phase-Locked Loop (PLL) with bypass capability, supporting both clock and crystal inputs. The component is housed in a 24-UFQFN exposed pad package and is currently in active production status. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same product family, ensuring direct functional replacement without circuit redesign.

Substitute Part Grouping Explanation

The CY2545QC010 belongs to the Infineon CY2545 base product family. Substitute parts within this family maintain identical electrical and mechanical specifications across all critical parameters that determine functional compatibility. Substitution is valid when the following parameters remain constant:

Maximum frequency: 166MHz
Number of circuits: 4
Input:Output ratio: 2:8
Supply voltage range: 2.25V ~ 3.6V
Operating temperature range: 0°C ~ 70°C
Package type: 24-UFQFN Exposed Pad
PLL configuration: Yes with Bypass
Input and output types: Clock, Crystal / Clock

Parts meeting these criteria are electrically and mechanically interchangeable without modification to the host circuit.

Engineering Selection Recommendations

Both the CY2545QC010 and CY2545QC022 are active production parts from Infineon Technologies with identical electrical and mechanical specifications. Both components are ROHS3 compliant and carry the same moisture sensitivity level classification. Selection between these parts may be based on inventory availability and procurement lead times, as no functional differentiation exists between the two variants. Both parts are suitable for applications requiring fanout distribution and clock generation within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can CY2545QC022 directly replace CY2545QC010 in an existing circuit?

A: Yes. Both parts share identical electrical specifications, including frequency range, supply voltage, operating temperature, and circuit configuration. The 24-UFQFN package pinout and functionality are equivalent, enabling direct substitution without circuit modification.

Q: Are there any differences in compliance or certification between these parts?

A: No. Both CY2545QC010 and CY2545QC022 carry identical RoHS3 compliance status and moisture sensitivity level (MSL 3, 168 hours). Both are REACH unaffected and classified under the same ECCN and HTSUS codes.

Q: What determines if a part is a valid substitute for the CY2545QC010?

A: Valid substitutes must maintain the following parameters: 166MHz maximum frequency, 4 circuits, 2:8 input:output ratio, 2.25V to 3.6V supply voltage, 0°C to 70°C operating temperature range, 24-UFQFN exposed pad package, and PLL with bypass configuration. Any deviation from these specifications disqualifies a part as a direct substitute.

Q: Is the 24-UFQFN package critical for substitution?

A: Yes. The package type is a critical mechanical parameter. Substitutes must use the identical 24-UFQFN exposed pad package to ensure PCB footprint compatibility and proper thermal management. Alternative packages are not interchangeable.

Q: Can these parts be used in applications requiring extended temperature ranges?

A: No. Both CY2545QC010 and CY2545QC022 are specified for 0°C to 70°C operating temperature. Applications requiring extended temperature ranges require alternative part selection outside this family.
