FIN1019MTC LVDS Transceiver Equivalent & Substitute Parts

Part Overview

The FIN1019MTC is a 1/1 full-duplex LVDS transceiver manufactured by onsemi, housed in a 14-TSSOP surface mount package. This component operates at 400 Mbps data rate with a 3V to 3.6V supply voltage range and supports industrial temperature ranges from -40°C to 85°C. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FIN1019MTC is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Protocol: LVDS
• Configuration: 1/1 (1 Driver / 1 Receiver)
• Duplex Mode: Full
• Package Type: 14-TSSOP
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C to 85°C

Allowable Parameter Variations:

• Data Rate: Substitute parts may exceed the 400 Mbps specification of the main part
• Supply Voltage: Substitute parts may have wider voltage ranges that encompass the 3V to 3.6V requirement

The identified substitute parts meet all mandatory matching criteria while maintaining or exceeding performance specifications.

Parameter Comparison

Engineering Selection Recommendations

FIN1019MTCX (Fairchild Semiconductor) is the primary substitute for the FIN1019MTC. This part maintains identical electrical specifications (400 Mbps data rate, 3V to 3.6V supply voltage) and physical packaging. The FIN1019MTCX holds active product status and carries ROHS3 compliance certification, making it suitable for new designs and legacy system replacements where the original onsemi part is unavailable.

DS90LV019TMTC/NOPB (Texas Instruments) is a secondary substitute option. While this part meets all mandatory package and functional requirements, it operates at a reduced maximum data rate of 100 Mbps compared to the 400 Mbps specification of the FIN1019MTC. The DS90LV019TMTC/NOPB features an extended supply voltage range (3V to 5.5V) and maintains active product status with ROHS3 compliance. This part is suitable for applications where the lower data rate is acceptable within system bandwidth requirements.

Frequently Asked Questions (FAQ)

Q: Can the FIN1019MTCX directly replace the FIN1019MTC in existing designs?

A: Yes. The FIN1019MTCX maintains identical electrical and physical specifications, including the same 14-TSSOP package footprint, supply voltage range, operating temperature range, and 400 Mbps data rate. No circuit modifications are required.

Q: What is the key difference between the FIN1019MTCX and DS90LV019TMTC/NOPB?

A: The primary difference is data rate capability. The FIN1019MTCX supports 400 Mbps, matching the original FIN1019MTC specification. The DS90LV019TMTC/NOPB operates at a maximum of 100 Mbps. Both parts share identical package geometry and operating temperature range. Selection depends on whether your application requires the higher bandwidth.

Q: Are all substitute parts RoHS compliant?

A: Yes. Both the FIN1019MTCX and DS90LV019TMTC/NOPB carry ROHS3 compliance certification. The original FIN1019MTC does not list RoHS status in available documentation.

Q: Can I use the DS90LV019TMTC/NOPB in a 400 Mbps application?

A: No. The DS90LV019TMTC/NOPB is rated for a maximum of 100 Mbps. Using this part in a 400 Mbps application would exceed its specified operating parameters and is not recommended.

Q: Are there any packaging differences between these parts?

A: No. All three parts use the identical 14-TSSOP (0.173", 4.40mm Width) surface mount package. PCB footprints and assembly processes remain unchanged.

Q: Why is the FIN1019MTC classified as obsolete?

A: The FIN1019MTC is no longer manufactured by onsemi. The FIN1019MTCX variant from Fairchild Semiconductor provides equivalent functionality and remains in active production.
