Substitute Part Grouping Explanation

Substitution for the CSP2510DPGG8 is determined by the following critical parameters:

Primary Compatibility Criteria:

Package type: 24-TSSOP (0.173", 4.40mm Width)
Supply voltage range: 3V ~ 3.6V
Operating temperature range: 0°C ~ 85°C
PLL with bypass functionality
Single circuit configuration
Surface mount mounting type

Frequency and Ratio Considerations: The CSP2510DPGG8 operates at a maximum frequency of 175MHz with a 1:10 input-to-output ratio. Substitute parts are grouped into two categories based on frequency capability:

175MHz Capable Substitutes (CDCVF2510 series): These parts match the maximum frequency specification of the original part. However, they feature a 2:11 input-to-output ratio and LVTTL signal levels, which differ from the original 1:10 ratio and Clock signal type.
125MHz Capable Substitutes (CDC2510 series): These parts operate at a lower maximum frequency of 125MHz but maintain the 1:10 input-to-output ratio and Clock signal type matching the original part.

The selection between these groups depends on the specific frequency and ratio requirements of the target application.

Engineering Selection Recommendations

For applications requiring 1:10 ratio and Clock signal compatibility:

The CDC2510 series (CDC2510CPW, CDC2510CPWG4, CDC2510CPWR) provides direct functional compatibility with the CSP2510DPGG8 in terms of input-to-output ratio and signal type. However, these parts are limited to 125MHz operation compared to the original 175MHz specification. CDC2510CPWR offers the highest inventory availability (16,546 units) and is packaged in Tape & Reel format suitable for production environments. All CDC2510 variants are ROHS3 compliant with MSL rating of 1 (Unlimited), providing superior moisture handling compared to the original part's MSL 3 rating.

For applications requiring 175MHz frequency capability:

The CDCVF2510 series (CDCVF2510APW, CDCVF2510APWR, CDCVF2510PW, CDCVF2510PWR) matches the 175MHz maximum frequency of the original part and maintains active product status. These parts feature LVTTL signal levels and a 2:11 input-to-output ratio, which differ from the original specifications. CDCVF2510PWR provides the highest inventory (17,883 units) and is actively supported by Texas Instruments. All CDCVF2510 variants are ROHS3 compliant with MSL rating of 1 (Unlimited).

Packaging considerations:

Tape & Reel (TR) packaged variants (CDC2510CPWR, CDCVF2510APWR, CDCVF2510PWR) are recommended for production volume applications. Tube packaged variants (CDC2510CPW, CDCVF2510APW, CDCVF2510PW) are suitable for lower-volume or prototype applications.

Frequently Asked Questions (FAQ)

Q: Can CDC2510 series parts directly replace the CSP2510DPGG8?

A: CDC2510 series parts are mechanically and electrically compatible in terms of package type, supply voltage, operating temperature, and input-to-output ratio (1:10). However, they operate at a maximum frequency of 125MHz compared to the original 175MHz specification. Substitution is valid only if your application operates below 125MHz.

Q: What is the difference between CDC2510 and CDCVF2510 series?

A: The CDC2510 series maintains the 1:10 input-to-output ratio and Clock signal type of the original part but is limited to 125MHz. The CDCVF2510 series supports the full 175MHz frequency but features a 2:11 ratio and LVTTL signal levels. Selection depends on whether your application prioritizes frequency capability or ratio/signal type compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all Texas Instruments substitute parts listed (CDC2510 and CDCVF2510 series) are ROHS3 compliant. The original Renesas CSP2510DPGG8 does not specify RoHS status.

Q: What does MSL rating mean for these parts?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to moisture before soldering. The original part has MSL 3 (168 hours maximum), while all Texas Instruments substitutes have MSL 1 (unlimited storage under controlled conditions). Lower MSL ratings provide greater flexibility in manufacturing and storage environments.

Q: Which substitute part has the best availability?

A: CDCVF2510PWR offers the highest inventory at 17,883 units, followed by CDC2510CPWR at 16,546 units. Both are actively stocked and available in production-friendly Tape & Reel packaging.

Q: Can I use CDCVF2510 parts if my application requires a 1:10 ratio?

A: No. CDCVF2510 parts feature a 2:11 input-to-output ratio, which differs from the required 1:10 ratio. Use CDC2510 series parts for 1:10 ratio applications, provided your frequency requirement does not exceed 125MHz.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is suitable for lower quantities and prototype applications, typically containing 13-25 units per tube. Tape & Reel packaging is designed for automated assembly and production environments, offering better handling and integration with pick-and-place equipment. Both packaging types contain identical components.
