Key Parameters

Substitute Part Grouping Explanation

Substitution for the FIN3384MTDX is determined by strict alignment of the following electrical and mechanical parameters:

• Function: Deserializer operation with identical input/output configuration
• Data Rate: 2.38Gbps serial data throughput
• Input/Output Interface: LVDS inputs with LVTTL outputs
• Channel Configuration: 4 inputs and 28 outputs
• Supply Voltage: 3V to 3.6V operating range
• Package: 56-TFSOP form factor for PCB compatibility
• Mounting: Surface mount technology

All substitute parts listed maintain these core parameters, ensuring functional and mechanical compatibility with the original FIN3384MTDX design.

Parameter Comparison

Engineering Selection Recommendations

FIN3386MTDX is the primary substitute from onsemi. It maintains identical electrical specifications and package form factor while offering active product status and ROHS3 compliance. The extended operating temperature range (-40°C to 85°C) provides broader environmental coverage compared to the original part. This option is recommended for designs requiring continuity with onsemi component sourcing.

DS90CR286AQMT/NOPB and DS90CR286AQMTX/NOPB are Texas Instruments alternatives that maintain the same 56-TFSOP package and 3V to 3.6V supply voltage. Both parts carry AEC-Q100 automotive qualification and ROHS3 compliance, making them suitable for automotive and industrial applications. The primary difference between these two is packaging format: DS90CR286AQMT/NOPB is supplied in Tube packaging, while DS90CR286AQMTX/NOPB is supplied in Tape & Reel format.

Selection should prioritize active product status and compliance certifications appropriate to the application environment.

Frequently Asked Questions (FAQ)

Q: Can FIN3386MTDX directly replace FIN3384MTDX in existing designs?

A: Yes. Both parts share identical function, data rate, input/output configuration, supply voltage, and package specifications. The FIN3386MTDX is the active equivalent with extended temperature range and improved compliance status.

Q: What is the difference between DS90CR286AQMT/NOPB and DS90CR286AQMTX/NOPB?

A: Both parts are functionally identical Texas Instruments alternatives. The difference is packaging format: DS90CR286AQMT/NOPB uses Tube packaging, while DS90CR286AQMTX/NOPB uses Tape & Reel format. Selection depends on production volume and assembly line requirements.

Q: Are the Texas Instruments parts suitable for automotive applications?

A: Yes. Both DS90CR286AQMT/NOPB and DS90CR286AQMTX/NOPB carry AEC-Q100 qualification, making them appropriate for automotive-grade designs.

Q: Does the extended temperature range of FIN3386MTDX affect compatibility?

A: No. The extended operating range (-40°C to 85°C versus -10°C to 70°C) represents improved capability and does not impact compatibility with designs specified for the original temperature range.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. FIN3386MTDX, DS90CR286AQMT/NOPB, and DS90CR286AQMTX/NOPB all carry ROHS3 compliance certification.

Q: What packaging options are available for these substitutes?

A: FIN3386MTDX is available in Cut Tape and Digi-Reel formats. DS90CR286AQMT/NOPB is supplied in Tube packaging. DS90CR286AQMTX/NOPB is supplied in Tape & Reel format. Selection should align with production assembly requirements.
