Substitute Part Grouping Explanation

Substitution eligibility for the CS2300CP-CZZR is determined by strict equivalence across the following critical parameters:

Frequency specification (75MHz maximum)
Input-to-output ratio (1:2)
PLL functionality (required)
Supply voltage range (3.1V ~ 4.6V)
Package type (10-MSOP surface mount)
Input/output signal type (Clock/Clock, non-differential)
Number of circuits (1)
Divider/Multiplier capability (Yes/Yes)

The CS2300P-DZZR meets all electrical and mechanical substitution criteria. Both parts share identical functional specifications, package geometry, and electrical operating parameters. The primary distinction lies in product lifecycle status and moisture sensitivity classification.

Engineering Selection Recommendations

The CS2300P-DZZR is a direct parametric equivalent to the CS2300CP-CZZR. Both components are manufactured by Cirrus Logic Inc. and maintain identical electrical and mechanical specifications across all critical functional parameters.

The CS2300P-DZZR carries Active product status, ensuring continued availability and manufacturing support. The CS2300CP-CZZR, designated as Last Time Buy, indicates production discontinuation and limited remaining inventory.

Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for industrial and commercial applications. The CS2300P-DZZR features improved moisture sensitivity classification (MSL 2, 1 Year) compared to the CS2300CP-CZZR (MSL 3, 168 Hours), providing enhanced reliability under standard storage and handling conditions.

For new designs and ongoing procurement, the CS2300P-DZZR is the appropriate selection. For legacy system maintenance requiring the original part number, the CS2300CP-CZZR remains functionally interchangeable until inventory depletion.

Frequently Asked Questions (FAQ)

Q: Can the CS2300P-DZZR replace the CS2300CP-CZZR in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters, including frequency response, supply voltage, operating temperature range, and package configuration. Direct substitution is supported without circuit modification.

Q: What is the significance of the Last Time Buy status on the CS2300CP-CZZR?

A: Last Time Buy indicates that Cirrus Logic Inc. has discontinued production of this part number. Existing inventory is finite and will not be replenished. The CS2300P-DZZR is the active production equivalent.

Q: Are there differences in moisture sensitivity between these parts?

A: Yes. The CS2300CP-CZZR is classified as MSL 3 (168 Hours), while the CS2300P-DZZR is classified as MSL 2 (1 Year). MSL 2 provides extended protection against moisture absorption during storage and handling. Both classifications are suitable for standard manufacturing and assembly processes.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the CS2300CP-CZZR and CS2300P-DZZR are ROHS3 compliant and REACH Unaffected. Both carry the same ECCN (EAR99) and HTSUS classification (8542.39.0001).

Q: Is the 10-MSOP package identical for both parts?

A: Yes. Both parts use the same 10-MSOP surface mount package with 0.118" width and 3.00mm height. PCB footprints and assembly processes are identical.
