FIN1019M LVDS Transceiver - Equivalent & Substitute Parts

Part Overview

The FIN1019M is a 1/1 full-duplex LVDS transceiver manufactured by onsemi, housed in a 14-SOIC 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 FIN1019M is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, design updates, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FIN1019M is determined by strict alignment of the following critical parameters:

• Protocol compatibility: LVDS transceiver architecture
• Channel configuration: 1/1 driver/receiver pair
• Duplex operation: Full-duplex capability
• Package form factor: 14-SOIC surface mount housing
• Operating temperature range: -40°C to 85°C minimum
• Moisture sensitivity classification: MSL 1 or equivalent

The DS90LV019TM/NOPB from Texas Instruments meets all substitution criteria. While the substitute part supports a wider supply voltage range (3V to 5.5V) and lower maximum data rate (100 Mbps), these parameters remain within acceptable operational boundaries for the FIN1019M application space. The identical package footprint, channel configuration, and temperature rating ensure mechanical and functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DS90LV019TM/NOPB is the designated substitute for the obsolete FIN1019M. Selection of this alternative is supported by the following factors:

• Active product status ensures long-term availability and supply chain continuity
• Identical package footprint (14-SOIC) permits direct board-level replacement without layout modification
• Matching channel configuration (1/1 full-duplex) maintains functional equivalence
• Identical operating temperature range (-40°C to 85°C) satisfies thermal requirements
• MSL 1 classification matches moisture sensitivity specifications
• ROHS3 compliance and REACH unaffected status align with regulatory requirements
• Wider supply voltage tolerance (3V to 5.5V) provides operational flexibility

Frequently Asked Questions (FAQ)

Q: Can the DS90LV019TM/NOPB directly replace the FIN1019M on existing PCBs?

A: Yes. Both components use identical 14-SOIC packaging with matching pin configurations. No PCB layout modifications are required for mechanical substitution.

Q: What is the impact of the lower data rate specification on the DS90LV019TM/NOPB?

A: The substitute part specifies 100 Mbps maximum data rate compared to the FIN1019M's 400 Mbps. Applications operating below 100 Mbps experience no functional impact. Systems requiring data rates above 100 Mbps must evaluate alternative solutions.

Q: Are there supply voltage compatibility concerns?

A: The FIN1019M operates within 3V to 3.6V. The DS90LV019TM/NOPB accepts 3V to 5.5V. When the substitute is powered within the FIN1019M's original voltage range (3V to 3.6V), no compatibility issues arise.

Q: What certifications apply to the substitute part?

A: The DS90LV019TM/NOPB carries ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original component.

Q: Is the FIN1019M available from current inventory?

A: The FIN1019M is classified as obsolete. The DS90LV019TM/NOPB is an active product with current manufacturing and distribution support.
