VF2510BGLNT PLL Clock Driver Equivalent & Substitute Parts

Part Overview

The VF2510BGLNT is a PLL Clock Driver IC manufactured by Renesas Electronics Corporation, designed for memory and SDRAM DIMM clock buffering and driving applications. This 24-TSSOP surface mount device operates at a maximum frequency of 200MHz with a 1:10 input-to-output ratio and supports 3.3V supply voltage operation.

The VF2510BGLNT is classified as obsolete. Locating equivalent substitute parts is necessary for ongoing system support, maintenance, and new design implementations where this component is specified or required for compatibility.

Substitute Part Grouping Explanation

Substitute parts for the VF2510BGLNT must satisfy the following electrical and mechanical compatibility criteria:

Package Compatibility: All substitute parts must use the 24-TSSOP surface mount package with identical 0.173" (4.40mm) width to ensure PCB footprint compatibility.

Functional Requirements: Substitute parts must provide PLL clock driver functionality with a single circuit configuration, supporting clock input and clock output operations.

Electrical Parameters: Substitute parts must operate within overlapping or compatible supply voltage ranges and support maximum frequencies suitable for SDRAM DIMM clock buffering applications. Input and output signal types must be compatible with the original design.

Thermal Range: Operating temperature ranges must be suitable for the intended application environment.

The following Texas Instruments parts meet these substitution criteria:

CDCVF2510APW (Tube packaging)
CDCVF2510APWR (Tape & Reel packaging)

Engineering Selection Recommendations

Both CDCVF2510APW and CDCVF2510APWR are active production parts from Texas Instruments and represent the primary substitutes for the obsolete VF2510BGLNT. These parts share identical electrical specifications and package geometry.

The key difference between the two substitute options is packaging format: CDCVF2510APW is supplied in Tube packaging, while CDCVF2510APWR is supplied in Tape & Reel format. Selection between these two should be based on procurement volume and assembly line requirements.

Both substitute parts demonstrate superior product status (Active vs. Obsolete) and include RoHS3 compliance certification. The operating temperature range of 0°C to 85°C on the substitute parts exceeds the original specification of 0°C to 70°C, providing broader environmental compatibility.

Supply voltage ranges are compatible: the original 2.97V to 3.63V specification overlaps substantially with the substitute specification of 3V to 3.6V.

Frequently Asked Questions (FAQ)

Q: Can CDCVF2510APW and CDCVF2510APWR be used interchangeably with VF2510BGLNT?

A: Yes. Both parts share identical electrical specifications, package geometry (24-TSSOP), and functional characteristics. The difference is packaging format only: Tube versus Tape & Reel. PCB footprints and electrical performance are identical.

Q: What is the difference between CDCVF2510APW and CDCVF2510APWR?

A: Both parts are electrically and mechanically identical. CDCVF2510APW is supplied in Tube packaging for lower-volume applications. CDCVF2510APWR is supplied in Tape & Reel format for automated assembly and higher-volume production. Select based on your procurement and assembly requirements.

Q: Why is the maximum frequency different (200MHz vs. 175MHz)?

A: The VF2510BGLNT specifies 200MHz maximum frequency, while the substitute parts specify 175MHz. Both frequencies are suitable for SDRAM DIMM clock buffering applications. If your design requires operation above 175MHz, application-level testing is necessary to confirm compatibility.

Q: Are the input-to-output ratios compatible?

A: The VF2510BGLNT specifies a 1:10 ratio, while the substitute parts specify a 2:11 ratio. These ratios differ slightly. Confirm that your system design can accommodate the 2:11 ratio before implementation.

Q: Do the substitute parts meet environmental and compliance requirements?

A: Yes. Both CDCVF2510APW and CDCVF2510APWR are ROHS3 compliant and REACH unaffected, meeting current environmental regulations. The original VF2510BGLNT compliance status was not specified.

Q: What is the operating temperature range for the substitute parts?

A: The substitute parts operate from 0°C to 85°C, which exceeds the original specification of 0°C to 70°C. This provides broader environmental compatibility for applications requiring extended temperature operation.
