PI3HDX612ZLDEX Equivalent & Substitute Parts

Part Overview

The PI3HDX612ZLDEX is an active HDMI buffer and redriver manufactured by Diodes Incorporated, designed for high-speed digital signal conditioning in HDMI applications. This 4-channel device operates at 6Gbps per channel and is housed in a 40-pin TQFN package with exposed pad. The component is currently in active production status with robust inventory availability. Alternative components may be required due to supply constraints, design revisions, or specific application requirements that necessitate equivalent functionality within the same electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI3HDX612ZLDEX is determined by strict alignment across the following critical parameters:

• Data Rate Capability: 6Gbps maximum per channel
• Channel Configuration: 4-channel architecture
• Signal Interface: CML input and output
• Signal Conditioning: Input equalization functionality
• Supply Voltage: 3V to 3.6V operating range
• Package Compatibility: 40-pin TQFN (3x6) with exposed pad
• Delay Characteristics: 0.5ns delay time
• Regulatory Compliance: ROHS3 and REACH status

Only components meeting all these parameters across electrical performance, signal characteristics, and physical packaging qualify as direct substitutes. No parameter relaxation or functional compromise is acceptable in substitute selection.

Engineering Selection Recommendations

The PI3HDX612ZLDEX maintains active production status with confirmed inventory of 4191 pieces in new original condition. Selection of substitute components must be based on:

Product Status Alignment: Only active production components qualify as substitutes. Obsolete or end-of-life parts do not meet substitution criteria.

Regulatory Compliance: Both the main part and any substitute must maintain identical ROHS3 compliance and REACH unaffected status to ensure regulatory continuity in end-product applications.

Certification Consistency: Moisture sensitivity level 1 (unlimited) indicates no special handling requirements. Substitute parts must maintain this classification to avoid introducing additional supply chain or assembly process constraints.

Package Integrity: The 40-WFQFN exposed pad package with 3x6mm footprint is critical for PCB layout compatibility. No package variant substitution is permissible.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the PI3HDX612ZLDEX?

A: A valid substitute must match all electrical parameters (6Gbps data rate, 4-channel configuration, CML signaling, 0.5ns delay, input equalization), supply specifications (3V to 3.6V, 460mA max), operating temperature range (-40°C to 70°C), and physical packaging (40-TQFN 3x6 with exposed pad). Regulatory status (ROHS3, REACH) must also align identically.

Q: Can I use a different package variant of this part?

A: No. The 40-WFQFN exposed pad package is a fixed requirement. Different package types, pin counts, or footprints are not acceptable substitutes and will require PCB redesign.

Q: Are there any functional differences between the main part and its substitute?

A: No. Substitutes must be parametrically identical across all specified electrical and mechanical characteristics. Any functional difference disqualifies a component from substitution eligibility.

Q: What is the significance of the 0.5ns delay time specification?

A: The 0.5ns delay time is a critical timing parameter for HDMI signal integrity in redriver applications. Substitute components must maintain this exact specification to preserve signal timing relationships in the application circuit.

Q: Does the MSL 1 rating affect substitute selection?

A: No. MSL 1 (unlimited) indicates the component has no moisture sensitivity restrictions. Substitutes must maintain this same MSL classification to avoid introducing special storage or handling requirements.

Q: Why is CML signaling important for substitution?

A: CML (Current Mode Logic) is the specified signal interface for both input and output. This determines the signal conditioning architecture and impedance characteristics. Substitutes must use identical CML signaling to ensure circuit compatibility.
