Substitute Part Grouping Explanation

Substitute parts for the CSP2510DPGG are identified based on strict alignment with the following critical parameters:

Primary Substitution Criteria:

Package Type: 24-TSSOP (0.173", 4.40mm Width) - mandatory for PCB compatibility
Supply Voltage Range: 3V to 3.6V - required for circuit operation
Operating Temperature Range: 0°C to 85°C - environmental specification match
PLL Configuration: Yes with Bypass - functional requirement
Number of Circuits: 1 - functional requirement
Mounting Type: Surface Mount - assembly compatibility

Secondary Compatibility Parameters:

Maximum Frequency: 175MHz or higher - performance requirement
Input/Output Signal Type: Clock-based signals
Differential Input/Output: No/No - signal configuration

Substitute parts are grouped into two categories based on input-to-output ratio compatibility:

Group 1 - Exact Ratio Match (1:10): CDC2510CPW, CDC2510CPWG4, CDC2510CPWR - These Texas Instruments parts maintain the 1:10 ratio but operate at 125MHz maximum frequency, which is lower than the original 175MHz specification.

Group 2 - Alternative Ratio (2:11): CDCVF2510APW, CDCVF2510APWR, CDCVF2510PW, CDCVF2510PWR - These Texas Instruments parts feature a 2:11 input-to-output ratio with 175MHz maximum frequency and LVTTL signal compatibility, offering higher frequency performance with modified ratio characteristics.

Engineering Selection Recommendations

For Direct Ratio Replacement (1:10): CDC2510CPWR is the recommended substitute when maintaining the exact 1:10 input-to-output ratio is required. This part is available in Tape & Reel packaging with 16,546 units in stock, providing supply continuity. However, the maximum frequency is limited to 125MHz compared to the original 175MHz specification. The part carries "Not For New Designs" status from Texas Instruments, indicating it is in mature production phase.

For Active Product Line Selection (2:11 Ratio): CDCVF2510PWR and CDCVF2510APWR are recommended for new designs requiring active product support. Both parts maintain 175MHz maximum frequency matching the original specification and carry Active product status from Texas Instruments. CDCVF2510PWR offers the highest inventory availability at 17,883 units in Tape & Reel packaging. These parts feature LVTTL signal compatibility and operate within the same 3V to 3.6V supply range and 0°C to 85°C temperature specification.

All substitute candidates maintain identical package geometry (24-TSSOP), supply voltage range, operating temperature range, MSL rating, and mounting type, ensuring PCB-level compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can CDC2510CPWR be used as a direct replacement for CSP2510DPGG?

A: CDC2510CPWR maintains the same 1:10 input-to-output ratio, 24-TSSOP package, 3V to 3.6V supply voltage, and 0°C to 85°C operating temperature range. However, the maximum frequency is 125MHz versus 175MHz for the original part. Substitution is valid only if the application operates below 125MHz.

Q: What is the difference between CDC2510CPWR and CDCVF2510PWR?

A: CDC2510CPWR operates at 125MHz maximum with 1:10 ratio and Clock signal type. CDCVF2510PWR operates at 175MHz maximum with 2:11 ratio and LVTTL signal type. Both share identical package, voltage, and temperature specifications. The CDCVF2510PWR is the active product line choice for new designs.

Q: Why do the CDCVF2510 parts have a different input-to-output ratio (2:11 instead of 1:10)?

A: The CDCVF2510 series represents a different product variant within the Texas Instruments clock driver portfolio. While the ratio differs, the parts maintain functional compatibility in applications where the 2:11 ratio meets system requirements. The 175MHz frequency capability and active product status make these parts suitable for modern designs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All Texas Instruments substitute parts (CDC2510 and CDCVF2510 series) carry RoHS3 compliance certification. The original Renesas CSP2510DPGG RoHS status is not specified in available documentation.

Q: What packaging options are available for substitute parts?

A: CDC2510CPWR and CDCVF2510APWR are available in Tape & Reel (TR) packaging. CDC2510CPW and CDCVF2510APW are available in Tube packaging. CDCVF2510PW and CDCVF2510PWR are available in Tube and Tape & Reel options respectively. All maintain the 24-TSSOP package geometry.

Q: Which substitute part has the best inventory availability?

A: CDCVF2510PWR offers the highest inventory with 17,883 units in stock, followed by CDC2510CPWR with 16,546 units. Both are available in Tape & Reel packaging suitable for production volume requirements.

Q: Can I use CDCVF2510 parts in existing designs without circuit modification?

A: CDCVF2510 parts are pin-compatible within the 24-TSSOP package and operate at identical supply voltage and temperature ranges. However, the 2:11 input-to-output ratio differs from the original 1:10 ratio. Circuit-level validation is required to confirm the ratio change does not affect system timing specifications.
