Equivalent & Substitute Parts for 2308-5HDCGI

Part Overview

The Renesas Electronics 2308-5HDCGI is a Multiplier, Zero Delay Buffer IC designed for clock/timing applications. This 16-SOIC surface mount device operates at a maximum frequency of 133.3MHz with a 1:8 input-to-output ratio and supports LVTTL signal levels. The device has reached obsolete product status, necessitating identification of functionally compatible alternatives for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2308-5HDCGI are identified based on the following critical parameters that determine functional compatibility:

Core Compatibility Criteria:

• Package / Case: 16-SOIC (0.154", 3.90mm Width) — identical physical footprint required for direct PCB replacement
• Mounting Type: Surface Mount — consistent assembly process
• Input Signal Level: LVTTL — compatible signal interface
• Output Signal Level: LVTTL — compatible signal interface
• Voltage - Supply: 3V ~ 3.6V — same supply voltage range
• Operating Temperature: -40°C ~ 85°C — same thermal operating range
• PLL: Yes with Bypass — functional capability match
• Number of Circuits: 1 — single circuit configuration

Frequency and Ratio Considerations: The substitute parts operate at higher maximum frequencies (200MHz versus 133.3MHz) and feature different input-to-output ratios (2:8 versus 1:8). These differences do not preclude substitution when the application requirements fall within the substitute part's operational envelope. The higher frequency capability of substitute parts provides additional design margin.

Parameter Comparison

Engineering Selection Recommendations

CDCVF25081D and CDCVF25081DR are the designated substitute parts for the obsolete 2308-5HDCGI. Both Texas Instruments alternatives maintain active product status, ensuring long-term availability and continued manufacturer support.

Compliance and Certifications: Both substitute parts carry ROHS3 compliance certification, meeting current environmental and regulatory requirements. The REACH status is unaffected for all three parts. Both substitutes maintain the same ECCN classification (EAR99) as the original part.

Packaging Differentiation: CDCVF25081D is supplied in Tube packaging, while CDCVF25081DR is supplied in Cut Tape (CT) and Digi-Reel format. Selection between these two variants depends on procurement volume and assembly line requirements. CDCVF25081DR offers higher inventory availability (6351 Pcs) compared to CDCVF25081D (1160 Pcs).

Functional Capability: The substitute parts operate at 200MHz maximum frequency, exceeding the original part's 133.3MHz specification. This provides additional operational margin for clock/timing applications. The input-to-output ratio difference (2:8 versus 1:8) must be evaluated against specific application requirements to ensure system-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can CDCVF25081D and CDCVF25081DR be used interchangeably?

A: Yes. Both parts are identical in electrical and mechanical specifications. The difference is packaging format: CDCVF25081D uses Tube packaging, while CDCVF25081DR uses Cut Tape and Digi-Reel format. Selection depends on procurement volume and assembly process requirements.

Q: What is the impact of the different input-to-output ratio (2:8 versus 1:8)?

A: The substitute parts feature a 2:8 ratio compared to the original 1:8 ratio. This difference affects the frequency multiplication factor and must be evaluated within the context of the specific application's clock distribution requirements. Applications operating within the substitute part's 200MHz maximum frequency specification can accommodate this ratio difference.

Q: Are the substitute parts pin-compatible with the 2308-5HDCGI?

A: Both substitute parts use the identical 16-SOIC (0.154", 3.90mm Width) package. Physical footprint compatibility is confirmed. Pin-level functional compatibility must be verified against the specific application schematic and signal routing.

Q: Why is the 2308-5HDCGI obsolete?

A: The 2308-5HDCGI has reached end-of-life status with Renesas Electronics. The Texas Instruments CDCVF25081 series represents the current active alternative for clock/timing multiplier and driver applications in this package class.

Q: What certifications do the substitute parts carry?

A: Both CDCVF25081D and CDCVF25081DR are ROHS3 compliant and carry EAR99 ECCN classification. Moisture Sensitivity Level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.
