CS2100P-DZZ Equivalent & Substitute Parts
Part Overview
The CS2100P-DZZ is a Fractional N Synthesizer IC manufactured by Cirrus Logic Inc., designed for clock and timing applications. This device operates at a maximum frequency of 75MHz and is housed in a 10-MSOP surface mount package. The part is currently in Active product status with 662 units in stock.
Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design flexibility is required across manufacturing batches. The CS2000CP-CZZ and CS2100CP-CZZ are available as parametric equivalents with identical electrical and mechanical specifications.

Substitute Part Grouping Explanation
Substitution eligibility for the CS2100P-DZZ is determined by the following critical parameters:
- Fractional N Synthesizer type with integrated PLL functionality
- Maximum frequency rating of 75MHz
- Supply voltage range of 3.1V ~ 4.6V
- Operating temperature range of -10°C ~ 70°C
- 10-MSOP surface mount package with 0.118" width (3.00mm)
- Divider and multiplier capability (Yes/Yes)
- ROHS3 compliance and MSL Level 2 rating
The CS2000CP-CZZ and CS2100CP-CZZ meet all these electrical and mechanical requirements and are therefore direct parametric equivalents. Both substitute parts maintain identical functional specifications and package dimensions, enabling direct board-level replacement.

Engineering Selection Recommendations
The CS2100P-DZZ is the primary selection for new designs due to its Active product status and continuous manufacturing availability. Both substitute parts—CS2000CP-CZZ and CS2100CP-CZZ—carry Last Time Buy status, indicating limited future availability.
All three parts maintain identical electrical performance, package specifications, and compliance certifications (ROHS3, REACH Unaffected, MSL Level 2). Selection between the three parts should be based on inventory requirements and supply chain planning rather than technical performance differences.
The CS2000CP-CZZ offers the highest inventory level at 17,799 units, making it suitable for high-volume production requirements. The CS2100CP-CZZ provides an intermediate inventory option with 4,029 units available.
Frequently Asked Questions (FAQ)
Q: Can CS2000CP-CZZ and CS2100CP-CZZ be used interchangeably with CS2100P-DZZ?
A: Yes. All three parts are parametric equivalents with identical electrical specifications, frequency ratings, supply voltage requirements, operating temperature ranges, and 10-MSOP package dimensions. Direct board-level substitution is supported without design modification.
Q: What is the significance of the Last Time Buy status on substitute parts?
A: Last Time Buy status indicates that CS2000CP-CZZ and CS2100CP-CZZ are in their final production phase. Inventory will not be replenished after current stock is depleted. For long-term supply assurance, CS2100P-DZZ (Active status) is the recommended selection.
Q: Are there any package or pinout differences between these parts?
A: No. All three parts use the identical 10-MSOP surface mount package with 0.118" width (3.00mm). Pinout and mechanical dimensions are identical, enabling direct PCB-level replacement without layout modifications.
Q: Do all parts meet the same compliance requirements?
A: Yes. CS2100P-DZZ, CS2000CP-CZZ, and CS2100CP-CZZ are all ROHS3 compliant, REACH unaffected, and carry MSL Level 2 (1 Year) moisture sensitivity ratings. Compliance certifications are identical across all three parts.
Q: Which part should be selected for new production designs?
A: CS2100P-DZZ is the recommended selection for new designs due to Active product status and assured long-term availability. Substitute parts should be reserved for legacy design support or high-volume scenarios where inventory levels justify their selection.
