Engineering Selection Recommendations

CS2000P-DZZR: This part is an active product with identical electrical and mechanical specifications to the main part. It features improved moisture sensitivity (MSL 2 versus MSL 3), providing superior reliability in humid storage and operational environments. Tape & Reel packaging is available.

CS210005-CZZR: This part is an active product with identical electrical specifications. It maintains RoHS compliance and offers MSL 2 moisture sensitivity. Packaging format differs from the main part specification.

CS2100P-DZZR: This part is an active product with identical electrical and mechanical specifications. It features improved moisture sensitivity (MSL 2 versus MSL 3) and maintains ROHS3 compliance. Tape & Reel packaging is available, matching the main part's packaging format.

All substitute parts are manufactured by Cirrus Logic Inc. and maintain compliance with REACH and EAR99 export control classifications. Selection should prioritize active products to ensure long-term supply availability and support.

Frequently Asked Questions (FAQ)

Q: Can CS2000P-DZZR replace CS2100CP-CZZR in existing designs? A: Yes. Both parts share identical electrical parameters (75MHz maximum frequency, 3.1V–4.6V supply, -10°C to 70°C operating range) and mechanical specifications (10-TFSOP, 10-MSOP package). The CS2000P-DZZR offers improved moisture sensitivity (MSL 2 versus MSL 3), making it suitable for direct substitution.

Q: What is the significance of MSL (Moisture Sensitivity Level) differences? A: MSL indicates the maximum time a component can be exposed to moisture before soldering. CS2100CP-CZZR has MSL 3 (168 hours), while substitute parts have MSL 2 (1 year). Lower MSL values provide extended shelf life and greater tolerance to humid storage conditions.

Q: Are all substitute parts available in Tape & Reel packaging? A: CS2000P-DZZR and CS2100P-DZZR are available in Tape & Reel (TR) packaging. CS210005-CZZR packaging format is not specified in the provided data.

Q: Why is the main part marked as Last Time Buy? A: Last Time Buy status indicates the manufacturer has discontinued production. Substitute parts with Active status ensure continued availability and long-term supply chain reliability.

Q: Do all parts meet the same environmental compliance standards? A: Yes. All parts are ROHS3 compliant (or RoHS compliant) and REACH unaffected, meeting current environmental regulations for electronic components.
