PI2EQX6874ZFE Equivalent & Substitute Parts

Part Overview

The PI2EQX6874ZFE is an 8-channel buffer and ReDriver interface component manufactured by Diodes Incorporated, designed for high-speed serial data applications including SAS2, SATA, and XAUI protocols. This component operates at data rates up to 6.5Gbps and provides input equalization and output pre-emphasis signal conditioning capabilities. The product is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI2EQX6874ZFE requires strict alignment across the following critical parameters:

Electrical Compatibility Parameters:

• Number of channels: 8 channels
• Data rate capability: 6.5Gbps maximum
• Input/output signal type: CML (Current Mode Logic)
• Signal conditioning features: Input equalization and output pre-emphasis
• Supply voltage: 1.2V
• Supply current: 800mA
• Propagation delay: 750ps

Physical & Environmental Parameters:

• Package type: 56-WFQFN with exposed pad
• Mounting type: Surface mount
• Operating temperature range: -40°C to 85°C
• Moisture sensitivity level: MSL 1

Compliance Parameters:

• RoHS3 compliance
• REACH unaffected status

Substitute parts must match all electrical parameters, maintain package compatibility, and satisfy compliance requirements. No parameter deviation is acceptable for direct substitution in existing designs.

Engineering Selection Recommendations

The PI2EQX6874ZFE is classified as an obsolete product. When sourcing replacement units or equivalent components, the following criteria apply:

Product Status Consideration: Obsolete status indicates limited or no ongoing manufacturing. Existing inventory may be available through authorized distributors, but long-term availability cannot be assured.

Compliance Verification: Any substitute part must maintain ROHS3 compliance and REACH unaffected status to satisfy current regulatory requirements for electronic components in regulated markets.

Parametric Matching: Direct substitution requires exact alignment of all electrical parameters, including 8-channel configuration, 6.5Gbps data rate capability, CML signal type, and integrated signal conditioning features. Package compatibility (56-WFQFN with exposed pad) and thermal operating range (-40°C to 85°C) must be preserved.

Supply Chain Strategy: For designs currently using the PI2EQX6874ZFE, evaluate long-term component availability through authorized Diodes Incorporated distributors. If obsolescence creates supply constraints, engage with the manufacturer or authorized representatives to identify current-generation ReDriver products that meet the same functional and electrical requirements.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the PI2EQX6874ZFE?

A: A valid substitute must match all electrical parameters: 8 channels, 6.5Gbps maximum data rate, CML input/output, input equalization and output pre-emphasis signal conditioning, 1.2V supply voltage, 800mA supply current, and 750ps delay time. The package must be 56-WFQFN with exposed pad, and compliance certifications (ROHS3, REACH unaffected) must be maintained.

Q: Can I use a different package type if the electrical specifications match?

A: No. Package compatibility is a mandatory substitution criterion. The 56-WFQFN with exposed pad is required for PCB layout, thermal management, and mechanical fit. Different package types are not acceptable substitutes.

Q: Is the PI2EQX6874ZFE still in production?

A: No. The product is classified as obsolete. Availability is limited to existing inventory from authorized distributors. Contact Diodes Incorporated or authorized representatives for current sourcing options.

Q: What should I do if I cannot find the PI2EQX6874ZFE?

A: Evaluate current-generation ReDriver products from Diodes Incorporated that meet the same functional requirements: 8-channel configuration, 6.5Gbps data rate, CML signaling, and integrated signal conditioning. Verify electrical and package compatibility before design implementation.

Q: Are there any parameter deviations I can accept in a substitute part?

A: No. All parameters listed in the Key Parameters table must match exactly. Any deviation in channel count, data rate, signal type, supply voltage, or package type disqualifies a component as a direct substitute.

Q: What is the significance of the 56-TQFN (11x5) package designation?

A: This specifies the physical dimensions and pin configuration of the component. The 11x5 millimeter footprint and 56-pin TQFN (Thin Quad Flat No-Lead) package are critical for PCB design, assembly, and thermal performance. Substitute parts must use identical package specifications.
