FIN3383MTDX Equivalent & Substitute Parts

Part Overview

The FIN3383MTDX is a 2.38Gbps serializer interface IC manufactured by onsemi, designed to convert 28 LVTTL inputs to 4 LVDS outputs in a 56-TSSOP package. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system support and new design implementations. The part operates within a 3V to 3.6V supply range and supports operating temperatures from -10°C to 70°C.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FIN3383MTDX are identified based on strict alignment with the following critical parameters:

• Package Compatibility: All substitutes must use the 56-TFSOP (0.240", 6.10mm Width) package in 56-TSSOP supplier format
• Voltage Supply Range: All substitutes must operate within 3V to 3.6V
• Operating Temperature Range: All substitutes must support -10°C to 70°C
• Interface Type: All substitutes must provide LVDS output capability
• Mounting Type: All substitutes must be surface mount

The substitute parts identified are manufactured by Texas Instruments and maintain active product status, providing long-term availability and support compared to the obsolete FIN3383MTDX.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts meet the mandatory electrical and mechanical compatibility requirements for the FIN3383MTDX. The following factors should guide selection:

Product Status & Availability: The DS90CR287MTD/NOPB, DS90CR287MTDX/NOPB, SN75LVDS83ADGGR, and SN75LVDS83BDGGR are all active products from Texas Instruments, ensuring long-term availability and manufacturing support. The FIN3383MTDX is obsolete and should be replaced in new designs.

Compliance & Certifications: All Texas Instruments substitutes are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The FIN3383MTDX compliance status is not fully specified.

Moisture Sensitivity: The FIN3383MTDX carries MSL 1 (unlimited), while all substitutes carry MSL 2 (1 year). This requires standard moisture control procedures during storage and handling for substitute parts.

Inventory & Packaging Options: DS90CR287MTDX/NOPB offers the highest inventory availability (9472 pcs) in Cut Tape and Digi-Reel packaging. SN75LVDS83BDGGR provides 27300 pcs in Cut Tape and Digi-Reel packaging. DS90CR287MTD/NOPB is available in Tube packaging with 2000 pcs in stock.

Frequently Asked Questions (FAQ)

Q: Can the SN75LVDS83ADGGR or SN75LVDS83BDGGR directly replace the FIN3383MTDX?

A: These parts share the same package, voltage supply range, operating temperature range, and LVDS output capability. However, functional differences exist in driver/receiver configuration. Verify that the specific pin configuration and signal routing are compatible with your application before substitution.

Q: What is the difference between DS90CR287MTD/NOPB and DS90CR287MTDX/NOPB?

A: Both parts are functionally equivalent interface ICs in the 56-TSSOP package with identical electrical specifications. The primary difference is packaging format: DS90CR287MTD/NOPB is supplied in Tube packaging, while DS90CR287MTDX/NOPB is supplied in Cut Tape and Digi-Reel format. Select based on your assembly process requirements.

Q: Are there any moisture handling differences between the FIN3383MTDX and the substitute parts?

A: Yes. The FIN3383MTDX has MSL 1 (unlimited moisture sensitivity), while all Texas Instruments substitutes have MSL 2 (1 year). Substitute parts require standard moisture control procedures, including storage in dry conditions and baking before reflow if exposed to humidity for extended periods.

Q: Do all substitute parts support the same data rate as the FIN3383MTDX?

A: The FIN3383MTDX specifies 2.38Gbps data rate. The DS90CR287 series does not specify data rate in the provided parameters. The SN75LVDS83 series does not specify data rate in the provided parameters. Verify data rate specifications with the manufacturer datasheets for your specific application requirements.

Q: Which substitute part should I select for new designs?

A: For new designs, select from the active Texas Instruments products: DS90CR287MTDX/NOPB, DS90CR287MTD/NOPB, SN75LVDS83ADGGR, or SN75LVDS83BDGGR. All meet the mandatory electrical and mechanical requirements. Choose based on packaging preference (Cut Tape/Digi-Reel vs. Tube), inventory availability, and functional compatibility with your specific application.
