FIN1048MTC LVDS Receiver 0/4 Equivalent & Substitute Parts

Part Overview

The FIN1048MTC is a 0/4 LVDS receiver interface IC manufactured by onsemi in a 16-TSSOP surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. The FIN1048MTC operates at 400 Mbps data rate with 3V to 3.6V supply voltage across an operating temperature range of -40°C to 85°C. Substitute parts must maintain functional equivalence in LVDS receiver topology, electrical performance parameters, and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the FIN1048MTC are grouped based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Critical Parameters for Substitution:

Protocol: LVDS (Low-Voltage Differential Signaling)
Number of Drivers/Receivers: 0/4 configuration
Package / Case: 16-TSSOP (0.173", 4.40mm Width)
Voltage - Supply: 3V ~ 3.6V
Mounting Type: Surface Mount
Moisture Sensitivity Level: 1 (Unlimited)

Secondary Parameters Affecting Compatibility:

Data Rate: 400 Mbps (minimum requirement; higher rates are acceptable)
Operating Temperature: -40°C ~ 85°C (minimum requirement; wider ranges are acceptable)

Substitute parts are classified as direct equivalents when all critical parameters match exactly. Parts with higher data rates or extended temperature ranges remain functionally compatible for applications requiring the FIN1048MTC specifications.

Engineering Selection Recommendations

Direct Equivalents (Recommended Primary Substitutes):

FIN1048MTCX, ADN4668ARUZ-REEL7, SN65LVDS048APW, and SN65LVDS048APWR are direct functional equivalents to the FIN1048MTC. These parts maintain identical electrical specifications (400 Mbps data rate, -40°C to 85°C operating temperature) and mechanical compatibility (16-TSSOP package). All substitute parts listed carry active product status with RoHS3 compliance and REACH unaffected certification, ensuring long-term availability and regulatory compliance.

Compatible Alternatives (Extended Performance):

MAX9122EUE+ operates at 500 Mbps, exceeding the FIN1048MTC specification while maintaining all other critical parameters. This part is suitable for applications where higher data rate capability provides design margin.

Reduced Performance Alternatives (Lower Data Rate):

SN65LVDS390PW, SN65LVDS390PWR, SN65LVDT390PWR, SN75LVDS390PW, and SN75LVDS390PWR operate at 200 Mbps. These parts are suitable only for applications where the system data rate requirement does not exceed 200 Mbps. SN75LVDS390PW and SN75LVDS390PWR operate across 0°C to 70°C, which is narrower than the FIN1048MTC range and unsuitable for applications requiring -40°C operation.

Packaging Considerations:

Packaging variants (Tube, Cut Tape & Digi-Reel, Tape & Reel) do not affect electrical or mechanical compatibility. Selection should align with procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can FIN1048MTCX directly replace FIN1048MTC?

A: Yes. FIN1048MTCX is a direct equivalent with identical electrical and mechanical specifications. The primary difference is product status (active versus obsolete) and packaging format availability.

Q: Is MAX9122EUE+ compatible with FIN1048MTC applications?

A: MAX9122EUE+ is electrically compatible for applications designed for FIN1048MTC. The 500 Mbps data rate exceeds the 400 Mbps requirement, providing additional performance margin. All other parameters match the FIN1048MTC specification.

Q: Can SN65LVDS390PW replace FIN1048MTC?

A: SN65LVDS390PW is mechanically and electrically compatible only for applications where system data rate does not exceed 200 Mbps. The reduced data rate specification makes this part unsuitable for systems requiring 400 Mbps operation.

Q: What is the difference between SN65LVDS048APW and SN65LVDS048APWR?

A: Both parts are electrically identical with matching specifications. The difference is packaging format: SN65LVDS048APW is supplied in Tube packaging, while SN65LVDS048APWR is supplied in Cut Tape & Digi-Reel format. Selection depends on procurement and assembly process requirements.

Q: Are SN75LVDS390PW and SN75LVDS390PWR suitable for -40°C operation?

A: No. Both parts operate across 0°C to 70°C, which does not meet the FIN1048MTC requirement of -40°C to 85°C. These parts are unsuitable for applications requiring operation below 0°C.

Q: Do all substitute parts meet RoHS and REACH compliance?

A: All substitute parts listed carry RoHS3 compliance and REACH unaffected certification, matching the regulatory status of the FIN1048MTC.
