PI6C20400BLE Equivalent & Substitute Parts

Part Overview

The PI6C20400BLE is a PCI Express (PCIe) clock buffer IC manufactured by Diodes Incorporated, designed to distribute 400MHz clock signals with a 1:4 input-to-output ratio. This device features HCSL (High-Speed Current Steering Logic) differential inputs and outputs, making it suitable for PCIe timing applications requiring precise clock distribution.

The PI6C20400BLE is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this clock buffer architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PI6C20400BLE are identified based on strict electrical and mechanical parameter matching within the clock buffer IC category. The substitution criteria are:

• Manufacturer: Diodes Incorporated (same manufacturer ensures design compatibility)
• Main Purpose: PCI Express (PCIe) clock distribution
• Frequency Specification: 400MHz maximum operating frequency
• Input/Output Configuration: 1:4 ratio with HCSL differential signaling on both input and output
• Supply Voltage: 3.135V ~ 3.465V operating range
• Temperature Range: -40°C ~ 85°C
• Package: 28-TSSOP surface mount package
• Compliance: ROHS3 compliant, MSL Level 1

Parts meeting all these parameters are classified as direct substitutes. Product status (active vs. obsolete) does not affect electrical substitutability but influences availability and long-term support considerations.

Parameter Comparison

Engineering Selection Recommendations

The PI6C20400BLEX is a direct electrical and mechanical substitute for the PI6C20400BLE. Both parts share identical electrical specifications, package geometry, and compliance certifications. The primary distinction is product status: the PI6C20400BLE is obsolete, while the PI6C20400BLEX is active.

For new designs or ongoing production requiring PCIe clock buffer functionality at 400MHz with 1:4 distribution, the PI6C20400BLEX is the appropriate selection. This part maintains full compatibility with existing PCB layouts and circuit designs developed for the PI6C20400BLE while ensuring continued availability and manufacturer support.

Both parts are ROHS3 compliant and carry MSL Level 1 rating, indicating no moisture sensitivity constraints during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can PI6C20400BLEX be used as a direct replacement for PI6C20400BLE in existing designs?

A: Yes. The PI6C20400BLEX is electrically and mechanically identical to the PI6C20400BLE. No circuit modifications, PCB layout changes, or firmware updates are required. The parts are pin-compatible and functionally equivalent.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: Product status reflects manufacturer support and supply availability. The PI6C20400BLE (obsolete) may have limited inventory and no ongoing technical support. The PI6C20400BLEX (active) is currently manufactured and supported by Diodes Incorporated, ensuring reliable supply and access to technical documentation.

Q: Are there any packaging differences between these parts?

A: Both parts use the 28-TSSOP surface mount package with identical dimensions (0.173" width, 4.40mm). Packaging options differ only in distribution format: PI6C20400BLE is supplied in standard packaging, while PI6C20400BLEX is available in Cut Tape (CT) and Digi-Reel® formats. These distribution formats do not affect component functionality or PCB assembly compatibility.

Q: What are the critical parameters for substitution in PCIe clock buffer applications?

A: The critical parameters are frequency specification (400MHz), input/output ratio (1:4), signal type (HCSL differential), supply voltage range (3.135V ~ 3.465V), and package type (28-TSSOP). Any deviation in these parameters would require circuit re-evaluation and potential design modifications.

Q: Are both parts compliant with environmental and regulatory standards?

A: Yes. Both PI6C20400BLE and PI6C20400BLEX are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry MSL Level 1 rating, indicating no moisture sensitivity limitations.
