CDCL1810RGZR Equivalent & Substitute Parts

Part Overview

The CDCL1810RGZR is a Clock Fanout Buffer (Distribution), Divider IC manufactured by Texas Instruments, designed for high-speed clock distribution applications. This 1:10 ratio device operates at frequencies up to 650 MHz with LVDS input and CML output, housed in a 48-VFQFN Exposed Pad package. The part is currently in active production status with 3600 units in stock. Substitute parts are identified when identical electrical specifications, package configuration, and compliance certifications are maintained across alternative manufacturing codes or tape & reel variants.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDCL1810RGZR are determined by strict equivalence across the following critical parameters:

• Base product number (CDCL1810)
• Functional type (Fanout Buffer with 1:10 distribution ratio)
• Maximum frequency specification (650 MHz)
• Input/output signal types (LVDS input, CML output)
• Supply voltage range (1.7V ~ 1.9V)
• Operating temperature range (-40°C ~ 85°C)
• Physical package (48-VFQFN Exposed Pad, 7x7mm)
• Compliance certifications (ROHS3, REACH Unaffected)
• Moisture sensitivity level (MSL 3)

The identified substitutes differ only in manufacturing code suffix, which indicates tape & reel packaging variants or production date codes assigned by Texas Instruments. These variants maintain identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CDCL1810RGZR, CDCL1810ARGZT, and CDCL1810RGZT—are active production devices from Texas Instruments with identical electrical specifications and package configurations. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation.

CDCL1810RGZT offers the highest inventory availability at 6153 units. CDCL1810RGZR maintains 3600 units in stock. CDCL1810ARGZT has limited availability at 775 units. All three parts maintain ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can CDCL1810ARGZT be used as a direct replacement for CDCL1810RGZR?

A: Yes. Both parts share identical electrical specifications, frequency performance, signal types, supply voltage requirements, operating temperature range, and physical package dimensions. The suffix difference indicates only manufacturing code or tape & reel variant assignment.

Q: Are there any differences in signal integrity or timing performance between these substitutes?

A: No. All three parts maintain the same 1:10 distribution ratio, 650 MHz maximum frequency, LVDS-to-CML signal conversion, and 1.7V to 1.9V supply voltage specification.

Q: Do all substitute parts have the same moisture sensitivity requirements?

A: Yes. All parts are classified as MSL 3 with a 168-hour floor life specification, requiring identical handling and storage protocols.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since all parts are functionally and mechanically identical, they can be used interchangeably within the same circuit design and PCB layout without modification.

Q: What is the significance of the different manufacturing codes (RGZR, ARGZT, RGZT)?

A: The manufacturing codes represent Texas Instruments' internal part numbering for tape & reel packaging variants or production date code assignments. These do not affect electrical performance or mechanical compatibility.

Q: Are all substitute parts currently in active production?

A: Yes. All three parts maintain active product status with Texas Instruments, ensuring continued availability and support.
