CDCF2510PWG4 Equivalent & Substitute Parts

Part Overview

The CDCF2510PWG4 is a 3.3V PLL Clock Driver/Buffer IC manufactured by Texas Instruments, designed for memory and DRAM DIMM clock distribution applications. This device features a single output with a 1:10 input-to-output ratio and operates at a maximum frequency of 140MHz. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDCF2510PWG4 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Package type: 24-TSSOP form factor (0.173", 4.40mm Width)
• Supply voltage range: 3V ~ 3.6V
• Operating temperature range: 0°C ~ 85°C
• PLL functionality: Required
• Single output circuit configuration
• Surface mount mounting type
• RoHS3 compliance and MSL Level 1 rating

Functional Parameters:

• Maximum frequency capability must meet or exceed 140MHz
• Input and output signal types must be compatible with LVTTL or equivalent logic levels
• Differential input/output configuration: No/No (single-ended operation)

The CDCVF2510APW qualifies as a direct substitute based on matching all mandatory criteria while providing enhanced frequency performance (175MHz maximum) and active product status.

Engineering Selection Recommendations

The CDCVF2510APW is the designated manufacturer-recommended substitute for the obsolete CDCF2510PWG4. Selection of this alternative is supported by:

• Identical package footprint and pinout compatibility (24-TSSOP)
• Matching supply voltage specifications (3V ~ 3.6V)
• Identical operating temperature range (0°C ~ 85°C)
• Active product status with current manufacturing availability
• Full RoHS3 compliance and MSL Level 1 rating
• Enhanced maximum frequency specification (175MHz vs. 140MHz), providing performance margin for existing applications
• Bypass-capable PLL function offering additional design flexibility

The CDCVF2510APW maintains backward compatibility with existing PCB layouts and system designs while providing the advantage of active product support and extended availability.

Frequently Asked Questions (FAQ)

Q: Can the CDCVF2510APW be used as a direct replacement for the CDCF2510PWG4 on existing PCBs?

A: Yes. Both devices use the identical 24-TSSOP package with matching pinout and footprint. No PCB modifications are required for substitution.

Q: What is the significance of the different input-to-output ratios (1:10 vs. 2:11)?

A: The input-to-output ratio defines the frequency multiplication factor. The CDCVF2510APW ratio of 2:11 provides a different multiplication characteristic. System-level validation is required to confirm functional equivalence in specific clock distribution applications.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL Level 1 ratings. No compliance barriers exist for substitution.

Q: Why is the CDCF2510PWG4 classified as obsolete?

A: Obsolescence indicates the part is no longer manufactured by Texas Instruments. The CDCVF2510APW represents the active alternative for new designs and legacy system support.

Q: What is the advantage of the CDCVF2510APW's higher maximum frequency specification?

A: The 175MHz maximum frequency of the CDCVF2510APW exceeds the 140MHz specification of the CDCF2510PWG4, providing operational margin and potential support for higher-speed memory applications.

Q: Are packaging options different between these parts?

A: The CDCF2510PWG4 is supplied in standard packaging, while the CDCVF2510APW is available in tube packaging. Both maintain the identical 24-TSSOP form factor.
