PCK2001MDB,118 Equivalent & Substitute Parts

Part Overview

The PCK2001MDB,118 is a Clock Fanout Buffer (Distribution) IC manufactured by NXP USA Inc., designed for 1:10 clock distribution applications with a maximum frequency of 150 MHz. This component features LVTTL input and output logic levels, operates across a supply voltage range of 3.135V to 3.465V, and is housed in a 28-SSOP surface mount package.

The PCK2001MDB,118 is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing system maintenance, design updates, and procurement requirements where original inventory is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCK2001MDB,118 are identified based on the following critical parameters that determine functional compatibility:

• 1:10 Clock Distribution Ratio: The substitute must provide identical input-to-output distribution capability
• LVTTL Logic Levels: Both input and output must support LVTTL signaling for direct interface compatibility
• Supply Voltage Range: 3.135V ~ 3.465V compatibility ensures operation within the same power delivery architecture
• Operating Temperature Range: 0°C ~ 70°C operational envelope must be maintained
• 28-SSOP Package: Physical and electrical footprint compatibility for PCB integration
• Surface Mount Technology: Mounting method must remain consistent with existing assembly processes

The CDC319DBR from Texas Instruments qualifies as a substitute based on these parameters. While the CDC319DBR operates at a maximum frequency of 100 MHz (compared to the PCK2001MDB,118 at 150 MHz), it meets all other critical substitution criteria and maintains full functional compatibility for applications operating within the 100 MHz frequency ceiling.

Parameter Comparison

Engineering Selection Recommendations

The CDC319DBR is the designated substitute for the obsolete PCK2001MDB,118. Selection of this substitute is supported by the following factors:

Product Status: The CDC319DBR maintains active product status with Texas Instruments, ensuring ongoing availability, technical support, and supply chain continuity. The PCK2001MDB,118 is obsolete, making the CDC319DBR the appropriate alternative for new procurement and system maintenance.

Compliance and Certifications: Both components are ROHS3 compliant and carry identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), ensuring equivalent environmental and regulatory compliance across applications.

Functional Compatibility: The CDC319DBR provides 1:10 clock distribution with LVTTL input and output logic levels, matching the core functional requirements of the PCK2001MDB,118. Both components operate within the identical supply voltage range (3.135V ~ 3.465V) and temperature envelope (0°C ~ 70°C), enabling direct substitution in existing circuit designs.

Package Compatibility: The 28-SSOP surface mount package is identical between both components, allowing direct PCB footprint compatibility without layout modifications.

Frequency Consideration: The CDC319DBR operates at a maximum frequency of 100 MHz, which is lower than the PCK2001MDB,118 specification of 150 MHz. Substitution is appropriate for applications operating at or below 100 MHz. Applications requiring operation above 100 MHz require alternative component selection.

Frequently Asked Questions (FAQ)

Q: Can the CDC319DBR directly replace the PCK2001MDB,118 in all applications?

A: The CDC319DBR is a direct substitute for applications operating at clock frequencies of 100 MHz or below. The maximum frequency specification of the CDC319DBR (100 MHz) is lower than the PCK2001MDB,118 (150 MHz). Applications requiring operation above 100 MHz must identify alternative components.

Q: Are the package footprints identical between these components?

A: Yes. Both the PCK2001MDB,118 and CDC319DBR use the 28-SSOP (0.209", 5.30mm Width) surface mount package. No PCB layout modifications are required for physical substitution.

Q: Do the supply voltage requirements differ between these components?

A: No. Both components operate within the identical supply voltage range of 3.135V to 3.465V. Power delivery architecture modifications are not necessary.

Q: What is the significance of the CDC319DBR supporting both LVTTL and TTL output levels?

A: The CDC319DBR output stage supports both LVTTL and TTL logic levels, providing additional interface flexibility compared to the PCK2001MDB,118, which supports LVTTL output only. This expanded output capability does not affect substitution compatibility and may provide additional design flexibility in new applications.

Q: Are there compliance or regulatory differences between these components?

A: No. Both components are ROHS3 compliant with identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited). Regulatory and environmental compliance requirements are equivalent.

Q: Why is the CDC319DBR classified as active while the PCK2001MDB,118 is obsolete?

A: The PCK2001MDB,118 has been discontinued by NXP USA Inc. and is no longer in active production. The CDC319DBR remains in active production by Texas Instruments, ensuring ongoing availability and technical support for new designs and system maintenance.
