Substitute Part Grouping Explanation

Substitute parts for the CS2100P-CZZ are determined by strict equivalence across the following critical parameters:

Fractional N Synthesizer topology with integrated PLL
Maximum frequency of 75MHz
Supply voltage range 3.1V ~ 4.6V
Operating temperature range -10°C ~ 70°C
10-MSOP surface mount package (0.118", 3.00mm Width)
Divider and multiplier functionality (2:2 input:output ratio)
Non-differential input and output configuration

All identified substitute parts maintain identical electrical and mechanical specifications. Substitution is valid based on these parameters alone. Differences in product status, packaging format (tube vs. alternative), or base product numbering do not affect functional equivalence.

Engineering Selection Recommendations

All substitute parts listed maintain full parametric equivalence to the CS2100P-CZZ. Selection among these alternatives should be based on the following factors:

Product Status Consideration: CS2000P-DZZ, CS210005-CZZ, and CS2100P-DZZ carry Active product status, indicating ongoing manufacturer support and availability. CS2100P-CZZ, CS2000CP-CZZ, and CS2100CP-CZZ are designated Last Time Buy, signaling limited future procurement windows.

Compliance Alignment: All parts maintain ROHS3 compliance or equivalent RoHS Compliant status, suitable for applications requiring environmental regulatory adherence.

Inventory Availability: CS2000CP-CZZ offers the highest current stock level (17799 Pcs), followed by CS2100CP-CZZ (4029 Pcs). Parts with Active status provide longer-term supply assurance compared to Last Time Buy designations.

Packaging Format: All parts are supplied in 10-MSOP surface mount packages with identical mechanical specifications, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can CS2000CP-CZZ be used as a direct replacement for CS2100P-CZZ?

A: Yes. Both parts are Fractional N Synthesizer ICs with identical electrical specifications: 75MHz maximum frequency, 3.1V–4.6V supply voltage, -10°C to 70°C operating temperature range, and 10-MSOP package configuration. Functional equivalence is confirmed across all critical parameters.

Q: What is the difference between the -CZZ and -DZZ suffix designations?

A: The suffix designations reflect different product status and packaging configurations within the Cirrus Logic product line. Both variants maintain identical electrical and mechanical specifications for the CS2100 and CS2000 base product numbers. Selection between them should be based on product status (Active vs. Last Time Buy) and inventory availability rather than functional differences.

Q: Is CS210005-CZZ compatible with designs using CS2100P-CZZ?

A: Yes. CS210005-CZZ maintains full parametric equivalence across all critical specifications: 75MHz frequency, 3.1V–4.6V supply voltage, -10°C to 70°C operating temperature, and 10-MSOP package. The different base product number does not affect functional compatibility.

Q: Which substitute part offers the best long-term availability?

A: CS2000P-DZZ, CS210005-CZZ, and CS2100P-DZZ carry Active product status, indicating ongoing manufacturer support. Among these, CS210005-CZZ and CS2100P-DZZ provide the most reliable long-term sourcing options compared to Last Time Buy parts.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts meet RoHS compliance requirements. CS2100P-CZZ, CS2000CP-CZZ, CS2100CP-CZZ, and CS2100P-DZZ are ROHS3 Compliant. CS2000P-DZZ and CS210005-CZZ are RoHS Compliant. Both designations satisfy environmental regulatory requirements for electronic component applications.
