Parameter Comparison

Engineering Selection Recommendations

CS2100P-DZZR is the primary substitute for CS2100P-CZZR. Both parts share identical base product number (CS2100), electrical specifications, package configuration, and compliance certifications. The difference in packaging designation (CZZR vs. DZZR) reflects supplier variation. CS2100P-DZZR maintains Active product status with higher current inventory availability (1033 pcs vs. 928 pcs), providing superior supply chain continuity.

CS2000P-DZZR is a parametric equivalent substitute. This part maintains all critical electrical parameters, package dimensions, and compliance requirements. The base product number change (CS2000 vs. CS2100) indicates a different device variant within the Cirrus Logic fractional N synthesizer family. CS2000P-DZZR is in Active status with comparable inventory levels (926 pcs).

CS210005-CZZR is a parametric equivalent substitute with identical electrical and mechanical specifications. This variant carries RoHS Compliance designation rather than ROHS3 Compliant status. Inventory availability is 844 pcs. Packaging designation is not specified for this part number variant.

All three substitute parts are suitable for direct replacement in applications requiring fractional N synthesis at 75MHz with 3.1V to 4.6V supply operation. Selection should prioritize parts in Active status to ensure long-term supply availability.

Frequently Asked Questions (FAQ)

Q: Can CS2100P-DZZR directly replace CS2100P-CZZR in existing designs?

A: Yes. Both parts are identical in electrical specifications, package type (10-TFSOP, 10-MSOP), and compliance certifications. The packaging designation suffix difference (CZZR vs. DZZR) represents supplier variation only. No design modifications are required.

Q: What is the difference between CS2100P-CZZR and CS2000P-DZZR?

A: Both parts are Fractional N Synthesizer ICs with identical operating parameters: 75MHz maximum frequency, 3.1V to 4.6V supply voltage, -10°C to 70°C operating temperature, and 10-MSOP package. The base product number difference (CS2100 vs. CS2000) indicates different device variants within the Cirrus Logic product line, but they are functionally equivalent for clock/timing applications.

Q: Why is CS2100P-CZZR marked as Last Time Buy?

A: Last Time Buy status indicates that Cirrus Logic has discontinued production of this specific part number variant. Active substitute parts (CS2100P-DZZR, CS2000P-DZZR, CS210005-CZZR) are available to ensure design continuity and supply chain flexibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. CS2100P-DZZR and CS2100P-CZZR are ROHS3 Compliant. CS2000P-DZZR is ROHS3 Compliant. CS210005-CZZR is RoHS Compliant. All parts meet environmental compliance requirements for electronic component manufacturing.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All parts listed carry MSL 2 (1 Year) rating. This indicates the parts require storage in controlled humidity conditions and have a one-year shelf life from the date of manufacture when stored at specified moisture levels.

Q: Can I use these parts interchangeably in production?

A: Yes, provided the substitute part maintains the same electrical specifications, package type, and compliance certifications. All listed substitutes meet these criteria and are suitable for production use. Verify part availability and lead times with your supplier before committing to production schedules.

Q: What is the package type for these fractional N synthesizer ICs?

A: All parts use 10-TFSOP, 10-MSOP package with 0.118" width and 3.00mm body width. This is a surface mount package suitable for automated assembly processes.
