CDCF2510PWRG4 Equivalent & Substitute Parts

Part Overview

The CDCF2510PWRG4 is a 3.3V PLL Clock Driver IC manufactured by Texas Instruments, designed for memory and DRAM DIMM clock buffering and driving applications. This device operates at a maximum frequency of 140MHz with a 1:10 input-to-output ratio and is packaged in a 24-TSSOP surface mount configuration.

The CDCF2510PWRG4 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this clock driver topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDCF2510PWRG4 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package / Case: 24-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• Voltage - Supply: 3V ~ 3.6V
• Number of Circuits: 1
• Operating Temperature: 0°C ~ 85°C
• Manufacturer: Texas Instruments

Secondary Compatibility Criteria:

• PLL functionality with clock driver capability
• Differential Input/Output: No/No
• RoHS3 Compliance
• MSL Level 1

The CDCVF2510APWR qualifies as a manufacturer-recommended substitute. While it operates at a higher maximum frequency (175MHz) and features a different input-to-output ratio (2:11), it maintains identical package geometry, supply voltage range, operating temperature range, and surface mount configuration. Both devices are ROHS3 compliant with MSL Level 1 ratings.

Parameter Comparison

Engineering Selection Recommendations

The CDCVF2510APWR is the manufacturer-recommended substitute for the obsolete CDCF2510PWRG4. Selection of this substitute is supported by:

• Active product status ensuring ongoing availability and supply chain support
• Identical package geometry and surface mount configuration enabling direct PCB compatibility
• Matching supply voltage range (3V ~ 3.6V) and operating temperature range (0°C ~ 85°C)
• ROHS3 compliance and MSL Level 1 rating maintaining regulatory and environmental standards
• Enhanced maximum frequency specification (175MHz vs. 140MHz) providing performance headroom

The difference in input-to-output ratio (2:11 vs. 1:10) and maximum frequency must be evaluated against specific system clock requirements to confirm functional compatibility in the target application.

Frequently Asked Questions (FAQ)

Q: Can the CDCVF2510APWR be used as a direct replacement for the CDCF2510PWRG4?

A: The CDCVF2510APWR shares identical package geometry (24-TSSOP), supply voltage range (3V ~ 3.6V), operating temperature range (0°C ~ 85°C), and surface mount configuration. However, the input-to-output ratio differs (2:11 vs. 1:10), and maximum frequency is higher (175MHz vs. 140MHz). Functional compatibility depends on whether the system clock architecture accommodates these parameter differences.

Q: What is the significance of the different input-to-output ratios?

A: The input-to-output ratio determines the frequency multiplication factor. The CDCF2510PWRG4 multiplies the input clock by 10, while the CDCVF2510APWR multiplies by 11/2 (5.5). System clock calculations must account for this difference to ensure correct output frequencies.

Q: Are both parts RoHS compliant?

A: Yes. Both the CDCF2510PWRG4 and CDCVF2510APWR are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity ratings.

Q: Why is the CDCF2510PWRG4 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The CDCVF2510APWR, classified as active, represents the current production alternative from Texas Instruments for this functional category.

Q: Are there any PCB layout considerations when substituting these parts?

A: Both devices use the 24-TSSOP package with identical pin pitch and body dimensions (0.173", 4.40mm width). PCB footprints are compatible. Pin-level functional mapping must be verified against device datasheets to ensure correct signal routing.
