FIN3386MTDX Equivalent & Substitute Parts

Part Overview

The FIN3386MTDX is a 2.38Gbps deserializer manufactured by onsemi, designed for high-speed serial-to-parallel data conversion in interface applications. This active product operates with LVDS inputs and LVTTL outputs, converting 4 serial input channels to 28 parallel output channels in a 56-TSSOP surface mount package. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility is required while maintaining functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FIN3386MTDX are qualified based on the following critical parameters that determine functional interchangeability:

• Package Compatibility: All substitutes must use the 56-TFSOP (0.240", 6.10mm Width) package to ensure PCB layout compatibility and mounting feasibility.
• Functional Equivalence: All substitutes must perform deserializer function with 4 LVDS inputs and 28 LVTTL outputs.
• Electrical Specifications: Supply voltage range (3V to 3.6V), input/output signal types, and channel configuration must match or exceed the main part specifications.
• Operating Temperature Range: All substitutes must support the -40°C to 85°C operating temperature range.
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status ensure regulatory alignment.

Two substitute parts meet these criteria: the DS90CR286AMTD/NOPB (National Semiconductor) and the SN65LVDS94DGGR (Texas Instruments). Both maintain identical package, channel configuration, voltage supply range, and operating temperature specifications as the FIN3386MTDX.

Parameter Comparison

Engineering Selection Recommendations

FIN3386MTDX (onsemi): Primary selection for new designs. Active product status with full ROHS3 compliance and MSL 2 rating. Highest specified data rate at 2.38Gbps. Recommended for applications requiring maximum performance margin within the 56-TSSOP interface deserializer category.

SN65LVDS94DGGR (Texas Instruments): Direct substitute with identical package, channel configuration, voltage supply, and operating temperature specifications. Active product status with ROHS3 compliance and MSL 2 rating. Data rate of 1.904Gbps is lower than the main part; suitable for applications where this performance level is sufficient. Extensive availability (3567 pcs in stock) supports supply chain flexibility.

DS90CR286AMTD/NOPB (National Semiconductor): Functional substitute with matching package, channel configuration, and voltage supply specifications. Active product status. Operating temperature range and data rate specifications not provided in available documentation. High inventory availability (3000 pcs in stock). Selection requires confirmation of operating temperature and performance specifications against application requirements.

Frequently Asked Questions (FAQ)

Q: Can the SN65LVDS94DGGR replace the FIN3386MTDX in all applications?

A: The SN65LVDS94DGGR is a functional substitute with identical package, input/output configuration, voltage supply range, and operating temperature specifications. The data rate difference (1.904Gbps vs. 2.38Gbps) must be evaluated against application bandwidth requirements. If the application operates at or below 1.904Gbps, direct substitution is valid.

Q: What are the critical parameters for deserializer substitution?

A: Package type (56-TFSOP), channel configuration (4 inputs, 28 outputs), signal types (LVDS input, LVTTL output), voltage supply range (3V to 3.6V), and operating temperature range (-40°C to 85°C) are the primary parameters determining substitution compatibility. Data rate specifications should be matched to application requirements.

Q: Are all substitute parts RoHS3 compliant?

A: The FIN3386MTDX and SN65LVDS94DGGR are confirmed ROHS3 compliant. The DS90CR286AMTD/NOPB RoHS status is not specified in available documentation and should be confirmed before selection.

Q: What is the MSL rating significance for these parts?

A: MSL 2 (1 Year) rating indicates the component can be stored for up to one year under controlled humidity conditions before soldering. Both the FIN3386MTDX and SN65LVDS94DGGR carry this rating. The DS90CR286AMTD/NOPB MSL rating is not specified.

Q: How does package compatibility affect substitution?

A: All three parts use the 56-TFSOP package with identical dimensions (0.240", 6.10mm width). This ensures PCB footprint compatibility, eliminating layout redesign requirements for direct substitution.

Q: What inventory considerations apply to these substitutes?

A: FIN3386MTDX: 1306 pcs available. SN65LVDS94DGGR: 3567 pcs available. DS90CR286AMTD/NOPB: 3000 pcs available. Substitute parts offer higher inventory levels, supporting supply chain continuity.
