CDC351DWG4 Equivalent & Substitute Parts

Part Overview

The CDC351DWG4 is a Clock Fanout Buffer (Distribution) IC manufactured by Texas Instruments, designed for 1:10 clock distribution at frequencies up to 100 MHz. This device features LVTTL input and output with tri-state capability, operating from 3V to 3.6V supply voltage in a 24-SOIC surface mount package.

The CDC351DWG4 has been discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDC351DWG4 is based on strict equivalence of the following critical parameters:

• Functional Type: Fanout Buffer (Distribution) IC with identical 1:10 input-to-output ratio
• Logic Levels: LVTTL input and LVTTL tri-state output
• Maximum Frequency: 100 MHz operation capability
• Supply Voltage Range: 3V to 3.6V
• Operating Temperature Range: 0°C to 70°C
• Package Configuration: 24-SOIC (0.295", 7.50mm Width) surface mount
• Compliance Standards: ROHS3 Compliant, REACH Unaffected

The CDC351DW qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The CDC351DW is the direct substitute for the CDC351DWG4. Both parts share identical electrical and mechanical specifications, with the primary distinction being product status: the CDC351DWG4 is discontinued while the CDC351DW remains in active production.

Selection of the CDC351DW is supported by:

• Identical functional performance across all specified parameters
• Full compliance with ROHS3 and REACH requirements
• Active product status ensuring ongoing availability
• Same 24-SOIC package footprint for direct PCB compatibility
• Equivalent moisture sensitivity classification

Frequently Asked Questions (FAQ)

Q: Can the CDC351DW be used as a direct replacement for the CDC351DWG4?

A: Yes. The CDC351DW is electrically and mechanically equivalent to the CDC351DWG4. All critical parameters including logic levels, frequency rating, supply voltage, operating temperature range, and package configuration are identical.

Q: Are there any differences in the 24-SOIC package between these parts?

A: No. Both parts use the same 24-SOIC (0.295", 7.50mm Width) package specification, ensuring identical PCB footprint and mounting compatibility.

Q: What is the primary reason for substitution?

A: The CDC351DWG4 has been discontinued at DiGi Electronics. The CDC351DW provides equivalent functionality with active product status and current availability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the CDC351DWG4 and CDC351DW are ROHS3 Compliant and REACH Unaffected, with identical Moisture Sensitivity Level (MSL) classification of 1 (Unlimited).

Q: Are the supply voltage and operating temperature ranges identical?

A: Yes. Both parts operate from 3V to 3.6V supply voltage and function across the 0°C to 70°C operating temperature range.
