HXT4101A-DNT Equivalent & Substitute Parts

Part Overview

The HXT4101A-DNT is a 1/0 Driver Fibre Channel die manufactured by Renesas Electronics Corporation, designed for high-speed serial interface applications. This component operates at 14 Gbps and is classified as obsolete, making identification of suitable alternatives essential for ongoing system support and new design implementations. The obsolete status necessitates evaluation of active substitute components that maintain functional compatibility within the Fibre Channel protocol ecosystem.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HXT4101A-DNT is determined by the following critical parameters:

• Protocol Compatibility: Both main and substitute parts must support Fibre Channel protocol
• Driver/Receiver Configuration: 1/0 driver/receiver count must be maintained
• Package Type: Die package format required for direct functional replacement
• Mounting Type: Surface mount technology consistency
• Manufacturer: Renesas Electronics Corporation maintains design continuity
• RoHS Compliance: ROHS3 compliance required for regulatory alignment
• Moisture Sensitivity: MSL 1 rating ensures equivalent handling requirements

The HXT6101-DNT qualifies as a substitute based on these parameters. While the data rate increases from 14 Gbps to 16 Gbps, this represents enhanced capability within the same protocol family and does not preclude substitution in applications designed for the original component.

Parameter Comparison

Engineering Selection Recommendations

The HXT6101-DNT is the designated substitute for the obsolete HXT4101A-DNT. Selection of this alternative is supported by the following factors:

• Product Status: The HXT6101-DNT maintains active production status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both components meet ROHS3 compliance requirements, maintaining environmental and regulatory alignment
• Functional Equivalence: Identical driver/receiver configuration (1/0) and die package format enable direct functional replacement
• Protocol Support: The HXT6101-DNT extends protocol support to include IEEE 802.3 in addition to Fibre Channel, providing enhanced compatibility
• Data Rate Enhancement: The increased data rate (16 Gbps versus 14 Gbps) represents backward-compatible capability improvement

Frequently Asked Questions (FAQ)

Q: Can the HXT6101-DNT directly replace the HXT4101A-DNT in existing designs?

A: Yes. Both components share identical driver/receiver configuration, die package format, surface mount technology, and RoHS3 compliance. The higher data rate of the HXT6101-DNT is compatible with applications designed for the original 14 Gbps specification.

Q: What is the significance of the data rate difference between these components?

A: The HXT6101-DNT operates at 16 Gbps compared to the HXT4101A-DNT at 14 Gbps. This represents enhanced performance capability and does not create compatibility issues in substitution scenarios, as the substitute component exceeds the original specification.

Q: Are there packaging differences between these components?

A: Both components are supplied in die package format. The HXT4101A-DNT was supplied without specified packaging, while the HXT6101-DNT is supplied in tray packaging. The die itself maintains identical form factor for integration purposes.

Q: Why is the HXT4101A-DNT classified as obsolete?

A: Obsolete status indicates that the component is no longer in active production. The HXT6101-DNT represents the current active alternative within the Renesas product line for this functional category.

Q: Are moisture sensitivity requirements equivalent between these components?

A: Yes. Both components carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity classification and handling requirements throughout the supply chain and assembly process.
