CDCLVD2108RGZR Equivalent & Substitute Parts

Part Overview

The CDCLVD2108RGZR is a Clock Fanout Buffer (Distribution) IC manufactured by Texas Instruments, designed for high-speed clock distribution applications. This 1:8 differential clock buffer operates at frequencies up to 800 MHz and supports multiple input standards (LVCMOS, LVDS, LVPECL) with LVDS output. The device is housed in a 48-VFQFN package with exposed pad and is currently in active production status with ROHS3 compliance.

Substitute parts are identified when they maintain identical electrical specifications and mechanical compatibility while differing only in packaging configuration or inventory source.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDCLVD2108RGZR is determined by strict equivalence across all electrical and mechanical parameters. The primary differentiator between the main part and its substitute is the packaging configuration (bulk vs. tape & reel).

Key Parameters Governing Substitution:

• Base product number (CDCLVD2108)
• Frequency specification (800 MHz maximum)
• Input/output differential configuration (Yes/Yes)
• Supply voltage range (2.375V ~ 2.625V)
• Operating temperature range (-40°C ~ 85°C)
• Physical package type (48-VFQFN Exposed Pad, 7x7mm)
• Compliance certifications (ROHS3, REACH Unaffected)

Parts meeting all these criteria are classified as parametric equivalents and may be substituted based on availability and packaging requirements.

Parameter Comparison

Engineering Selection Recommendations

Both CDCLVD2108RGZR and CDCLVD2108RGZT are active production devices from Texas Instruments with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on procurement requirements and assembly processes.

The CDCLVD2108RGZR is supplied in bulk packaging, suitable for applications with flexible component handling requirements. The CDCLVD2108RGZT is supplied in tape & reel configuration, optimized for automated pick-and-place assembly operations and high-volume manufacturing environments.

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for commercial and industrial applications. Moisture sensitivity level 3 (168 hours) applies to both variants and requires standard handling procedures during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can CDCLVD2108RGZT be used as a direct replacement for CDCLVD2108RGZR?

A: Yes. Both parts are parametric equivalents with identical electrical performance, frequency specifications, input/output configurations, supply voltage requirements, and operating temperature ranges. The only difference is packaging format (tape & reel vs. bulk).

Q: What is the significance of the packaging difference between RGZR and RGZT?

A: The suffix indicates packaging configuration. RGZR denotes bulk packaging suitable for manual or semi-automated assembly. RGZT denotes tape & reel packaging optimized for automated surface mount assembly lines. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both parts use the same 48-VFQFN package with 7x7mm dimensions and exposed pad. PCB footprints, thermal characteristics, and electrical behavior are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CDCLVD2108RGZR and CDCLVD2108RGZT are ROHS3 compliant and REACH unaffected. Moisture sensitivity level 3 (168 hours) applies to both variants.

Q: Which part should be selected for high-volume production?

A: CDCLVD2108RGZT (tape & reel) is recommended for high-volume automated assembly due to compatibility with pick-and-place equipment and tape feeder systems.

Q: Are there inventory or lead time differences between these parts?

A: Inventory levels may vary. CDCLVD2108RGZR currently has 2805 pcs in stock, while CDCLVD2108RGZT has 1214 pcs in stock. Lead times and availability should be confirmed with your supplier.
