CDCFR83DBQG4 Equivalent & Substitute Parts

Part Overview

The CDCFR83DBQG4 is a Memory RDRAM Clock/Frequency Generator IC manufactured by Texas Instruments, operating at 533MHz with a single output in 24-SSOP surface mount packaging. This part is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, redesign, and procurement planning. Direct manufacturer substitutes and cross-compatible alternatives from other manufacturers are available to support continued application support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDCFR83DBQG4 is determined by the following critical parameters:

• Package Compatibility: 24-SSOP surface mount package with 0.154" width (3.90mm) is mandatory for PCB layout compatibility
• Electrical Specifications: Supply voltage range 3.135V ~ 3.465V, PLL functionality, 1:1 input-to-output ratio, and single circuit configuration
• Frequency Performance: Maximum frequency of 533MHz or higher supports the original application requirements
• Application Domain: Memory RDRAM clock generation with clock input and clock output
• Compliance: RoHS3 compliance required for regulatory alignment

Substitute parts are grouped into two categories:

Category 1 - Direct Texas Instruments Substitute: CDCFR83ADBQ shares identical electrical specifications, package, and base product number with the main part, differing only in product status (Active vs. Obsolete) and packaging format (Tube).

Category 2 - Cross-Manufacturer Alternatives: Renesas Electronics 9212AF series parts (9212AF-13LF-IN0 and 9212AF-13LFT-IN0) provide functional equivalence with enhanced frequency capability (600MHz) and identical package/voltage specifications, suitable for applications where higher frequency margin is acceptable.

Parameter Comparison

Engineering Selection Recommendations

CDCFR83ADBQ is the primary substitute for direct replacement. This part maintains identical electrical specifications, package configuration, and base product number as the CDCFR83DBQG4. The only substantive differences are product status (Active vs. Obsolete) and packaging format (Tube vs. original packaging). This part is recommended for applications requiring exact specification matching and continued support from Texas Instruments.

9212AF-13LF-IN0 and 9212AF-13LFT-IN0 are cross-manufacturer alternatives suitable for applications where operating temperature range and MSL rating differences are acceptable. These Renesas parts provide higher frequency capability (600MHz vs. 533MHz), which offers additional performance margin. The reduced operating temperature range (0°C ~ 70°C vs. -40°C ~ 85°C) and improved MSL rating (1 vs. 2) must be evaluated against specific application requirements. Both parts maintain identical supply voltage, package, and core functional specifications.

Selection between the two Renesas variants depends on specific application thermal and reliability requirements, as both provide equivalent electrical performance.

Frequently Asked Questions (FAQ)

Q: Can CDCFR83ADBQ be used as a direct replacement for CDCFR83DBQG4?

A: Yes. CDCFR83ADBQ is a direct substitute with identical electrical specifications, package configuration, and functional characteristics. The primary difference is product status (Active vs. Obsolete), making CDCFR83ADBQ the preferred choice for new procurement and system maintenance.

Q: What are the key differences between Texas Instruments and Renesas alternatives?

A: The Renesas 9212AF series provides higher maximum frequency (600MHz vs. 533MHz) and superior MSL rating (1 vs. 2). However, the operating temperature range is narrower (0°C ~ 70°C vs. -40°C ~ 85°C). All parts share identical supply voltage, package, and core RDRAM clock generation functionality.

Q: Are the 9212AF-13LF-IN0 and 9212AF-13LFT-IN0 interchangeable?

A: Both parts provide identical electrical and functional specifications. Selection between them depends on application-specific thermal and reliability requirements. Consult Renesas documentation for detailed performance characteristics of each variant.

Q: Does package compatibility extend to PCB layout?

A: Yes. All substitute parts use the 24-SSOP package with 0.154" (3.90mm) width, ensuring direct PCB footprint compatibility without layout modifications.

Q: What compliance certifications apply to all substitute options?

A: All parts listed are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement and deployment.

Q: Should operating temperature range differences affect my selection?

A: Operating temperature range differences between the CDCFR83ADBQ (-40°C ~ 85°C) and Renesas alternatives (0°C ~ 70°C) must be evaluated against your specific application environment. Applications requiring extended low-temperature operation should retain the Texas Instruments option.
